I agree it is probably not a good idea to run proxies or relays on a network only connected via tunnels. That would pose a load on AMPRGW. In that case it would be better to run them there.

The C program was written to mimic the Java version closely but in a more efficient way, both because it is in C and because a single instance can run multiple proxies. Later I received the C source of the relay program from EchoLink and merged its functions with the proxy program so these can both run on the same system. This is in full agreement with EchoLink, and they very much welcome the hosting of proxies and relays around the world to help users that are on limited internet connections or are not proficient in configuring port forwarding on their routers. Fortunately in our circles we have people who understand the internet and its protocols. (vs the applications that are now called "the internet") Rob

As you know, I don't agree with that. We should not segregate our addresses into different classes and force everyone into some class depending on what they want to do. It is a stopgap measure that will lead to endless changes and work, and it isn't even clear what "internet based amateur radio services" are exactly. For example, our repeaters are on Echolink on their AMPRnet address, they would be such services, we would have to route part of that space deeply into our network to get "special" addresses all the way there. Not going to happen! At the moment I am in contact with the Jonathan from Echolink and he is interested in setting up more relays as his existing relays in the US are getting overloaded. (he has temporarily moved some US users to our relays in Amsterdam) I think now that this is under change we could suggest moving everything to AMPRnet and it should solve the NAT problem there is now. Maybe the directory server could have both an AMPRnet and a public address to resolve remaining issues. Rob

New Mikrotik Vulnerability

by Nigel Vander Houwen

Hello All, We’ve (HamWAN) become aware of a new vulnerability on the Mikrotik devices that could allow an attacker to grab passwords off of the devices. If you block WinBox access you should be safe, but I’d recommend upgrading as soon as possible as well. More information about this vulnerability, as well as what versions are impacted, and what the patched version numbers are, are available from Mikrotik here: https://forum.mikrotik.com/viewtopic.php?f=21&t=133533 <https://forum.mikrotik.com/viewtopic.php?f=21&t=133533> Thanks, Nigel

Re: [44net] Echolink proxy/relay hosting

by Rob Janssen

> I found your C program in your follow up emails so seemed like I > should have everything I need. Sorry for the confusion, initially I > thought i needed to contact you for the C program. It probably wasn't clear in my first message... there is no need to contact me to deploy Echolink PROXY servers, the C program has been on my server for a long time (others are using it as well) and it can be installed on AMPRnet or commercial IP addresses alike. However, there are already quite some proxy servers and there is no immediate need for new ones, although they are always welcome. The call was mainly to get a number of new RELAY hosting sites, as there are currently not enough of them. Running PROXY servers is a good way to get some experience using the program, making sure it is started automatically and remains running, arranging for the extra addresses on the system (I do that using a script that does "ip addr add 44.137.75.$i dev eth0" in a loop, but it can be handled via the native network management of the distribution just as well. just don't create an extra interface for each) Once that is all clear and comfortable, RELAY servers can be configured (about 10, but in such areas as the US west coast maybe 5 is better as there are several volunteers now) and then you can contact me or K1RFD with the IP addresses so that they are going to get registered so they are really used. This is not required for PROXY servers, these register themselves automatically. Rob

Note it isn't really a beginner project, it assumes you are familiar with running a Linux system and compiling your own software on it. As a baseline, you are supposed to know what to do when you find a .tar.gz file and seeing that it contains a README, a .c file, a Makefile and an example configuration file.

Echolink proxy/relay hosting

by Rob Janssen

For some time we have been hosting Echolink proxies and relays on the system that is the gateway for 44.137.0.0/16 (BGP routed) in Amsterdam, Netherlands. We use a /24 subnet for that. Such proxies and relays facilitate the use if Echolink by users and repeaters that are behind NAT or are otherwise firewalled. About 100 repeaters around the world use our proxies, and over 600 users of the mobile app use our relays. Each Echolink proxy and relay requires a different IPv4 address. This can be a static address on internet, but often people have no /24 to spare for such things. AMPRnet provides the required address space. (unfortunately with an unintended side-effect, but in general it works well) For performance of the Echolink system it would be best when there are more places with a similar setup, distributed around the globe. Are there other BGP-routed sites outside Europe where such a service could be run? I have written a C program for this, that uses considerably less resources than the original Java software. On a 2.67GHz XEON server it causes a load around 0.05 for our 200 proxies and 10 relays. Of course it makes some network traffic, about 3 GB/day for the relays and similar for the proxies. When you have your gateway located in a suitable datacenter and are interested in such a setup to facilitate Echolink, please send me an e-mail and I can provide more info. Maybe we could even get the whole echolink.org infra hosted on AMPRnet space, which would solve the problem there now is with partially connected AMPRnet networks. (when the directory server is on AMPRnet, the problem with NAT between HAMNET and internet disappears) Rob

IMHO the preferred solution for this is to setup regional routing points where IPIP (and preferably BGP announcement) is possible, and where those users that have limited internet connections can connect via a VPN technology that still works for them. This way, their HAMNET traffic can be forwarded untranslated. It is the method that we use, and various others do it as well. As was shown before on this thread, VM/VPS services that can be used for this are widely available. And those do not suffer from having CGNAT or dynamic addresses. At least not yet. Rob

Of course for directly connected networks there will be no NAT, but there are those networks that are connected to internet via consumer internet connections (and no IPIP tunneling) and the traffic from those networks to the 44.190 space will pass through NAT routers.

I could ask about getting a /24 BGP > announced, so I could participate. That would be great! You can start getting a /24 (from your country network or from that 44.190 network, that does not really matter when you are not close to another network like Germany) and setup your system to be on the tunnel mesh. Then you can experiment with the software. In parallel you can get your BGP announcement fixed. > One thing I am not seeing addressed by this proposal is what happens > with the nodes themselves, which are the the most problematic part of > Echolink (and IRLP) due to their incompatibility with NAT (requiring > port forwarding to work at all). That is what the whole proxy/relay thing is about. A proxy lives on a system with unlimited UDP access from/to internet (port 5198/5199) and it also listens on port 8100 (default) for TCP connections from a repeater, link or user who is behind NAT. When a user connects it relays the UDP traffic from those ports to the TCP connection, and vice-versa. So it solves the NAT problem for that specific user, while preserving full functionality (the user behind the proxy can connect to several other stations and accept connections from other stations all at the same time). But a proxy can be used only by one user at the same time, that is why you want like 200 proxies. Proxies register themselves at Echolink.org, and a user wanting to use one can retrieve a list from the server and select one, some clients can automatically pick a non-busy proxy from that list. The Echolinks server sorts the list by geolocation distance to the requester, so your own proxies will appear at the top of the list. At least, when you have setup geolocation properly for your subnet. When you carve your subnet out of a country network this will work automatically when your coordinator has properly registered the country network. When he/she hasn't, your subnet will likely appear as located in San Diego, California. But you can fix that by sending a couple of registration requests to the most important geolocation providers, easlily found by googling for IP geolocation. This is another disaddvantage of the 44.190 space: you will certainly have to solve this problem yourself. A relay is a bit different. It allows only limited functionality: only outgoing connections, only a single destination at a time. It is used by default by the phone apps. A relay can serve multiple users at the same time, but the group of users can only connect to different destinations. When a user of a relay wants to connect to a destination (e.g. a popular repeater) that has already been connected by another user, the relay will refuse the connection and the app will have to hop over to another relay to try it there. That is why it is suggested to run 10 relays at each site. Relays are not automatically registered. They need to be manually registered at Echolink, who will put them in a geo DNS so users will get their address when querying relay.echolink.org and being closest to your relay. Try a dig -t a relay.echolink.org to see what it returns for you (most likely it will return our relays at 44.137.75.x in Amsterdam, not really close for you :-) That is what we are trying to solve by getting some more relays deployed. But first you can experiment with proxies, you can turn them on or off at your own will. Once you have started to run relays you need to take care that they remain running or when you want to quit, to tell that to the Echolink people so they can take them out of the pool, so users will not have to try to reach them in vain (until they try one that still works).

It requires network skills, and access to telecom operator > data centers. I think end-users or teams should not try to use eBGP unless they want to do it as another learning project as part of their AMPRnet gateway. Announcing your AMPRnet allocation on internet is simply a matter of telling your colocation/VPS hosting company that you have portable address space that you want to announce on internet and route that to your server or router. That is a standard change in their portfolio, they do that for lots of other customers and for them it is a simple matter of configuration in their existing network. They know how to do it and they already monitor it. When you do it yourself, you will have to get an AS, peering, setup your router, cope with the vast amount of routes and the processing and storage they require, etc. Not something to embark on lightly, and usually not necessary at all.

I wonder if it would be beneficial for those three to > pool their resources in some way? I agree that is not an optimal situation. It would be better to cooperate and maybe setup 3 or 5 relays each, and some proxies. It can be good to have some redundancy but it makes little sense to have 30 relays and 600 proxies all in the same state. I wasn't aware that this is the case, the USA is big and relays in California, New York and Texas would have been fine :-) Rob

by Rob Janssen

> I just applied for a /24 out of 44.190/16, to help with this endeavor. > I’ll be announcing the prefix out of a commercial datacenter in Fremont, CA under ASN 7247. I advise you (like is best for everyone who announces 44Net space on BGP) to make the system part of the IPIP tunnel mesh as well. I.e. make a tunl0 interface and run ampr-ripd on it, register it as a gateway using an extra IP address outside the /24 subnet. Add only the routes received over RIP, not a default route to ampr-gw. Of course you have a default route to your BGP router. This ensures that you are reachable for all AMPRnet hosts as well as normal internet systems, even when they cannot route their traffic transparently over internet themselves. It looks like we have 3 interested parties in the US and Canada, which would certainly help out for now. It would be nice if someone in the far east or Australia could join in. We always have a large number of users from Thailand, for example. Rob

Of > course, this will raise compatibility issues and routing problems. But > that's our job to find solutions :-) In general I think that is true. But in this particular case, that experiment is just there to work around unfortunate decisions made in the past. I can understand that it is now a lot of work to re-work the German HAMNET to make it compatible with a plain routed address space, but I do not see it as my responsibility to jump through hoops instead. When it would be a simple change, I would not have a problem. But as it is now, it is just as much work for us to cover their irregularities than it is for them to adapt their network. In that case I favor the "clean solution". > Here, in Corsica, we'll try to adapt our home-made system (OpenVPN > tunnels to two central gateways, and OSPF routing through 10.0.0.0/8 > private addressing) to AMPR addressing.

All the specific > routing and firewalling has to be tone only there. That is very similar to what we do here on the 44.137.0.0/16 network and you will not encounter the difficulties of NAT when you do it that way. All traffic internal and outside of your network is just plain routed. We use OpenVPN only for end-users that connect to our gateway and get 44Net space but only over the tunnels. However, that is the "novice class" of AMPRnet, we really do not want users to connect that way forever. They should use radio links, and when no access point is available they should get together and establish one. And that is developing rapidly. Of course access points would ideally be linked to other access points via radio, but until their density is sufficient to make that possible we also allow a VPN connection to a central router located in the datacenter, either GRE or L2TP/IPsec, and we run BGP over that connection so it can be used for the connectivity to AMPRnet or as a backup in case their are problems with the radio link. Radio links have preference in the recommended BGP setup. In this network we have untranslated internet access for every station because we do not directly send traffic on a user's internet connection (only the tunneled traffic to the central router that forwards the encapsulated 44Net packets to internet). In my opinion that is the correct way to do it. Of course if you want to setup many gateways like that across a larger country, the practical difficulty is that you need to negotiate BGP routing in many places. It is so much easier to just give in on that and go out via NAT over some local amateur's internet connection. But it causes the problems that Jann is now facing. Rob

Fwd: Massive IP blockings in Russia

[This has been forwarded to a number of mailing lists, but in case you haven't already seen it, you may find it of interest. This copy was received from the NANOG list. - Brian] Begin forwarded message: From: Alexander Isavnin <isavnin(a)gmail.com> Subject: [cooperation-wg] Massive IP blockings in Russia Date: April 17, 2018 at 1:36:33 PM EDT To: cooperation-wg(a)ripe.net Dear colleagues! I'm not pleased to inform you that RosComNadzor, a Russian Communication supervisory body, has started blocking huge ranges of IPs belonging to different cloud infrastructures, mostly Amazon and Google Cloud. Those ranges include: 13.52.0.0/14, 13.56.0.0/14, 18.184.0.0/15, 18.194.0.0/15, 18.196.0.0/15, 34.192.0.0/10, 34.240.0.0/13, 34.248.0.0/13, 35.156.0.0/14, 35.160.0.0/13, 35.176.0.0/15, 52.0.0.0/11, 52.192.0.0/11, 52.208.0.0/13, 52.28.0.0/15, 52.58.0.0/15, 54.144.0.0/12, 54.160.0.0/12, 54.228.0.0/15, 54.72.0.0/15, 54.88.0.0/16. Russian ISPs MUST fully block all traffic to such networks. The list is frequently updated and gets automatically propagated to ISP every once in a while, failure to block any address may result in 1500eur fine. The infrastructure listed above is being added to the blocklist under 'counter-terrorist and counter-extremist' order of the General Prosecutor Office, #27-31-2015/Id4082-15, issued in 2015 and often used for blocking an arbitrary unwanted content. The real reason for such blocking is an attempt to cut access to Telegram messenger, which refused to provide end-to-end encryption keys to the Federal Security Service (previously known as KGB). This is a case similar to San-Bernardino shooter's, where the FBI was denied access to the shooter's iPhone, but courts in Russia have made completely opposite decision. Telegram's infrastructure is being blocked by a different decision by RosKomNadzor, #2-1779/2018. Cloud infrastructures are being blocked for massive proxy and VPN hosting used to dodge messenger blocking. It is said, that more Apple and Google networks may be blocked soon for apps updates and push notifications delivery for Telegram. We hope to still have the global IP connectivity to keep you informed about how the situation develops. Do not be surprised if some of your services placed in cloud infrastructures will miss Russian customers. You can monitor the number of IP addresses, domains and URLs to be blocked in Russia at the https://2018.schors.spb.ru/ page (run by the famous ENOG community member Phil Kulin).

Different networks prefer and use different solutions. Some use an independent domain, some use sub-delegated subdomains, others are directly under ampr.org. Each of them of course has advantages and disadvantages and each sees it in a different way. On the Dutch network we put our addresses directly under .ampr.org and use the main DNS servers. For updating, I am using a script that automatically sends the updates to the server based on a local hosts file I update with newly assigned addresses. Whenever I run the script, which automatically happens once a day, the diff between the current and previous version is made and all changes are sent to the robot by mail, and appear in the global DNS some minutes later. I also download the zone file and keep it locally for use when the internet connection fails. Systems using our local resolvers (44.137.0.1 and 44.137.0.2) still have .ampr.org resolution, for those addresses not sub-delegated. This way I don't have to worry about providing DNS service on internet (which is a can of worms...) and still everyone has access to our names. Reverse also works, which is usually a problem on the independent networks. Rob

Re: [44net] New Global DNS server

by Rob Janssen

> Tell that to Cisco that uses 1.1.1.1 as part of their default config for the wireless access points. It appears that Cisco is well aware of the mistake that they made, and the default has been changed to 192.0.2.1 which is a properly reserved address for this. I see recommendations to change this address dating back to 2010, so by now it should have been changed by most active admins, and if not it will not really break anything unless users are using hardwired DNS settings and use the new 1.1.1.1 service. However, in wireless systems like this, users will likely use DHCP to set their DNS resolvers, and it will work at least until the admin changes the DNS advertised via DHCP and does not realize that 1.1.1.1 is already in use in their own system. I tried reaching the 1.1.1.1 DNS service via 4 different ISPs here in the Netherlands and it works OK on all of them. Apparently the use of 1.1.1.1 in routers is not too big of an issue. Rob

Bill; A few years back I went to configure my 44.44/16 local net so it included 44.44.44.44. The second it became live, my circuit lost link to it's tiedown due to excessive botnet flood traffic. It seems as if they like to use 44.44.44.44 as a test IP of sorts not knowing it's hitting UCSD. ... just an FYI for ya.

Re: [44net] MikroTik worm - please check your RouterOS version!

by Rob Janssen

> I recommend disabling the access to unneeded management services and to > the remaining ones, restricting the access to them from the networks > used by the administrators. Of course. And we had that already in place on the routers inside our own part of the network (which was deployed to facilitate our co-channel diversity repeater network). However, above I was discussing the settings on our internet gateway. I cannot control what all the individual amateurs, with varying networking skills, do on their routers at home, but by filtering inbound connects to port 8291 I can protect them from the current problem. There now are 430.000 addresses in the scan I did last night. only net-44 addresses: 44.140.129.12 44-25-128-124.ip.hamwan.net[44.25.128.124] 44.34.131.144 But of course, when people start filtering outbound 8291 connections, it is not a complete picture.

Re: [44net] MikroTik worm - please check your RouterOS version!

by Rob Janssen

> it is not wise to block port 8291, because the exploitable service is > on http port 80 tcp. The worm uses port 8291 to identify possible victims (when it can connect to port 8291 it assumes there is a MikroTik router on that address), then attacks it on port 80 and some other ports that people may likely have set as an alternative for HTTP access to the router (8080 etc). So blocking port 8291 effectively blocks the worm in its current version, while not destroying the useful port 80. Of course experience with earlier events like this shows that such a worm typically evolves and may skip the port 8291 scan later, rendering this block ineffective. For now, I have blocked access to port 8291 from addresses outside AMPRnet on our gateway. Of course this restriction will be lifted when/if this worm stops operation. It appears to be controlled via a peer-to-peer network and it looks like it is a version of an existing worm that has been active on network cameras/recorders, routers from other manufacturers, etc, all running embedded Linux.

MikroTik worm - please check your RouterOS version!

by Rob Janssen

> All these should be good now, I've check the upgrade and it's on the newest > code. Please let me know if you see anything else. I'll run another scan (actually: a trace) tonight. It has to run for about 8-10 hours to catch everything, it appears. I just trace for SYN to port 8291 and get the source addresses. Unfortunately it cannot be done using a simple tshark -i eth0 -f "tcp dst port 8291" because tshark collects session state information and its memory use balloons under the millions of session open attempts it sees. So I use: while true do tshark -i eth0 -f "tcp dst port 8291" -c 20000 | fgrep '[SYN]' | sed -e 's/ ->.*//' -e 's/.* //' >>/tmp/syn8291 done Of course it would also be possible to limit it to AMPRnet: tshark -i eth0 -f "tcp dst port 8291 and src net 44.0.0.0/8" Rob

In the message I used the word "router" a couple of times, but it does not matter if it is a router or WiFi device, they all run the same software. When your device is on the above list, it has already been compromised. (probably at least one device on AMPRnet has been infected from internet and now it is infecting other devices inside AMPRnet, so you can be affected even when you have no internet access at all) However, the good news is that it appears that updating the RouterOS to 6.40.6 (bugfix) or 6.41.3 (current) is going to render the worm ineffective, it appears there is no real need to netinstall. When you have internet access, updating is a simple matter of clicking "check for updates" in the system->packages menu, select "current" or "bugfix" channel and click "download&install". Of course this does not work when you have no internet access, but then you can still download the desired npk files from mikrotik.com, upload them in the device and reboot. Rob

MikroTik worm - please check your RouterOS version!

by Rob Janssen

Likely unrelated to the issue with the rogue gateway servers, please note that this weekend an exploit was launched that affects MikroTik routers running RouterOS older than 6.38.5 and that has its webservice (WebFig) open to the outside network. These get infected via the webservice and start a worm that scans for other routers to infect. Once it is inside your network it may propagate to other devices. It will scan for the usual MikroTik configuration interfaces, of which port 8291 (winbox) is most easily identified. (the others, 23, 80 etc are already scanned so often that it is difficult to identify the source) I did a trace of about 10 hours on the 44.137.0.0/16 network and over that period it was scanned by over 345.000 unique IP addresses on the internet, and randomly connecting back to a few of them returns an old version RouterOS every time... Disturbingly, there are also a couple of AMPRnet IP addresses on that list! They are mainly in two different networks. Unfortunately they do not appear in ampr.org reverse-DNS. wlan1.w7hr-sunnyslope.hamwan.net[44.24.240.110] wlan.kd7tqn.hamwan.net[44.24.240.221] wlan1.baldi.we7x.hamwan.net[44.24.240.222] poe.haystack.hamwan.net[44.24.241.41] 44-25-128-124.ip.hamwan.net[44.25.128.124] r1.crystal.hamwan.net[44.25.128.169] lan.r1.beacon.hamwan.net[44.25.64.65] ether1.ap.beacon.hamwan.net[44.25.64.73] 44.34.128.100 44.34.128.101 vrrp.hil.memhamwan.net[44.34.128.102] 44.34.128.103 ptpsco.leb.memhamwan.net[44.34.128.163] ptpazo.leb.memhamwan.net[44.34.128.184] 44.34.128.34 44.34.128.35 44.34.128.36 44.34.128.39 44.34.128.62 44.34.128.94 44.34.128.99 44.34.129.114 44.34.129.117 r2.mno.memhamwan.net[44.34.129.35] ptphil.mno.memhamwan.net[44.34.129.38] sec1.mno.memhamwan.net[44.34.129.40] sec2.mno.memhamwan.net[44.34.129.41] 44.34.129.42 44.34.129.66 44.34.129.67 44.34.129.73 44.34.131.144 AP-120.StPete.flscg.org[44.98.249.67] AP-240.StPete.flscg.org[44.98.249.68] AP-A-250.tampa.flscg.org[44.98.249.7] W9CR-Mgmt.StPete.flscg.org[44.98.249.76] AP-B-330.tampa.flscg.org[44.98.249.8] AP-C-110.tampa.flscg.org[44.98.249.9] 44.103.35.26 44.140.129.12 When you know who owns one of the above systems, please advise them that their router is compromised and that they have to update it.

When you run a MikroTik router and have not updated RouterOS, please update it to at least 6.40.6 (select bugfix-only in the updater) or the current version 6.41.3. In the latter case, be aware of the issues around updating from 6.40 to 6.41 in complicated switched configurations. And of course, always configure a firewall that disallows access to the configuration interfaces from the internet, as always for devices like this. Rob

Re: [44net] gateways without subnets

by Rob Janssen

.> That is correct - there are plenty of gateways in the portal that have no subnets attached to them, but they are filtered out of the encap list. Ok, then apparently these "rogue gateways" (they happen to be all from Poland) are using some method to use the encap file to load tunnel interfaces and static routes. I had expected them to use the script that Marius wrote for MikroTik, but in that case they would not receive the RIP broadcasts and so would not be able to build all those tunnels (and send MikroTik neighbor discovery on them). I suspect there has been some "how to setup an AMPRnet gateway" doc going around in Poland... Tom SP2L is already looking at it. Maybe you can just remove all gateways that have had no subnets for some time. Although that will likely not fix anything... Rob

gateways without subnets

by Rob Janssen

Lately I see a number of gateways that are registered without subnets, but still they send traffic. When tracing it, it appears to be usually traffic like MikroTik neighbor discovery. It gets logged in our firewall because it is IP-encap traffic coming from an address that is not in the IP-encap routing table. And it isn't in the IP-encap routing table because that gateway does not have subnets. Would it be an idea to not send the RIP announcements to gateways without a registered subnet? It would not be useful to them anyway, I think. Rob

Re: [44net] gateways without subnets

by Rob Janssen

> The RIP sender sends RIP only to gateways listed in the encap table, > unless a bug has surfaced that I wasn't aware of. That code has been > stable for several years, so I doubt it. Does that table contain only gateways that actually have routes to them? Or is there also a listing for those that only are registered in the portal but with "No subnets"? I wonder how those gateways know the route to us to transmit tunnel data when they do not actually route anything themselves? They appear to be MikroTiks so most likely running the script by Marius YO2LOJ and that would have to receive the RIP data to bring up the tunnels. Rob

I don't see anything wrong with that, this is just a single host on the tunnel network. What I am wondering about is the gateways that do not have anything routed to them at all. Look in the portal and view in subnet mode, there are many gateways that show nothing there. Rob

Script to transfer routes to HSMM OLSR

by lleachii＠aol.com

Hey all, We're still working in the Washington, DC area on our HSMM Mesh network. At this point, I've been solving an issue when - those who have gateways and routes to AMPR will properly route. The only solution thus far is - those in the area with direct interconnections to AMPR as well as the Internet, will have to route them (lol). This requires announcing specific routes on the network. Mesh uses OLSR. My plan: - I'll make an Ethernet interface that is on the Mesh, we plan to get an allocation from AMPRNet (soon) for this - I'll run OLSR on this interface The script: - The current dynamic firewall script that now runs (see Wiki), will take the 44 networks and announce them in HNA I need assistance with developing that new portion of the script. I'm currently working on setting up a test to an adjacent HSMM node. Why can't the Mesh speak RIP44? - It will, we plan to setup another service with public keys that will change our DDNS name to the main router, it will start an election for if an Operator looses a good route via their Internet to AMPRGW. - While we plan to run the Mesh's tunnel with BGP eventually, the network will be configured to assume that the route to 0.0.0.0/0 is general on OLSR, and there are multiple gateways, others authorized to announce the Internet will use more specific routes like 0.0.0.0/1 and 128.0.0.0/1...etc...the main router will announce the Internet to the mesh by 255 /8 networks. - This network will be hybrid, unless you connection track the packet, it can return any direction - Masquerade when necessary, lol 73, - Lynwood KB3VWG

44.103/16 Coordinator Request

by Fredric Moses

Hello, I am wondering if there is a way we can take over as the coordinator for the 44.103/16 Michigan2 Block. Currently all the allocations in this /16 are to our microwave projects here in Michigan and it seems there is an issue with requesting a /24 that will be BGP announced from a separate location then our current allocations. I made a request on 2018-02-07 the coordinator requested I submit a utilization for one of our /19’s. We currently have a /19 /21 /23 /24 in our project now but I responded with the /19’s utilization report as requested. On 2018-02-14 the coordinator responded with : Fred, Your request will be ready RSN (Real Soon Now) I said thanks. On 2018-03-01 I asked for a status update. 2018-03-03 the coordinator responded: I expect next week. That week has now come and gone with no response or allocation. If a coordinator can not be changed out we would be willing to re-ip into a new /16 block that we can issue requests for IP’s in a more timely matter like our HamWAN brothers do out in the western US area. -- Fredric Moses - W8FSM - WQOG498 fred(a)moses.bz

Re: [44net] TNC for Raspberry pi that support 9600 Baud ?

by Rob Janssen

> At minimum, just a USB sound card ($5 US) and some way to key up your > radio. The Direwolf UserGuide details all this for you. On a Raspberry > Pi, a simple transistor circuit and a GPIO pin off the Pi is all you need. For software guys, it is now possible to make receive-only installations with even less hardware. On our co-channel diversity repeater system we have sites where an RTL DVB-T stick is used with SVXlink "remotetrx" configured to provide a number of virtual NBFM receivers where some of them are connected to the SVXlink master site to receive voice to be transmitted over the repeater, and other virtual receivers are connected via a loopback audio device to a direwolf process used to gateway the received APRS packets to the aprs2.net As the APRS frequency on 70cm is in the process of being changed, we receive on both the old and new frequency and also on 2 different repeater input frequencies, all with a single stick (and a bandpass in front of it, of course). I have even tested an SSB input to the repeater, which worked fine too. It is possible to add receivers and connect them to some application without touching the soldering iron, without even going to the site. It is really wonderful what software can do today... Rob

White space radio

by Steve L

This radio will be field tested soon at an area school. I look forward to hearing more and will report back when I do: http://www.metricsystems.com/ I figured I'd point it out to the list enough though I suspect the price point is not for the typical radio amateur. It would seem a company making such a thing would have a limited market, so if it could be unlocked to cover ham freq's that might provide a small secondary market. Either way, hams looking to move data might also want to research white space radios as I suspect this sort of thing will be more common. PS: I see the dunderheads in Newington have proposed some changes to the hobby. Sadly anything to do with data/bandwidth isn't part of it.

DMR trafic behave on AmprNet

by R P

About a year and a half ago I have asked how good will be the AmprNet to use to connect DMR repeaters So finaly i have made a HotSpot and connected it to the AmprNet and it connect to our Server via the AmprNet I use tunnel to UCSD and not BGP so traffic travel to UCSD The results are impressive No problem at all although the latency is big no words loose or packet loss The only thing i see is a bit delay until the Hotspot start to transmit and this is (probably ) because the latency so the PTT command delay a bit It is a high power hotspot consist of a 25 Watt radio connected to a MMDVM system so users use it and i didnt get any complain of any disconnection or any issue of networking or service so far If you are interested the statistic of the MikroTik Router that handle the AmprNet traffic show about 12Kbit/Sec UDP when the data flow from the hotspot to the server Ronen - 4Z4ZQ http://www.ronen.org Ronen Pinchooks (4Z4ZQ) WebSite<http://www.ronen.org/> www.ronen.org ronen.org (Ronen Pinchooks (4Z4ZQ) WebSite) is hosted by domainavenue.com

Routing of 44.0.0.0/8 how are routes announced to users?

by Benoit Panizzon

Dear List I'm pretty newly connected to hamnet, and also work at an ISP. I always assumed 44.0.0.0/8 would not be announced to the internet, but only routed privately on hamnet. Now I see routing issues I don't quite understand as for me this looks like routing is completely broken... On the internet core router I see that 44.0.0.0/8 is being announced by AS7377 (UCSD). But IP Addresses from the swiss HamNet range are not reachable via AS7377. So what is the point announcing the whole range to the internet? There is no 'more specific' route to 44.142.200.1 On the other hand I cannot reach parts of hamnet via hamnet. Take for example the Primary DNS of ampr.org: ampr.org. 3600 IN SOA ampr.org. ampr.org has address 44.0.0.1 1 gateway (157.161.57.65) 2.947 ms 2.887 ms 2.847 ms 2 mikrotik-hamnet.woody.ch (192.168.57.243) 4.937 ms 4.920 ms 4.887 ms 3 rf0.am-32.hb9am.ch.ampr.org (44.142.162.97) 21.810 ms 24.858 ms 29.860 ms 4 bb-hb9am-30.db0wbd.ch.ampr.org (44.224.90.81) 29.847 ms 32.792 ms 32.771 ms 5 wan-db0wbd.hc.r1.ampr.org (44.148.240.45) 78.907 ms 81.925 ms 84.438 ms 6 dc1-dc2.hc.r1.ampr.org (44.148.255.253) 97.808 ms 98.107 ms 113.973 ms 7 wan-db0gw.db0fhn.ch.ampr.org (44.224.122.2) 113.986 ms 113.149 ms 118.384 ms 8 db0fhn.ch.ampr.org (44.130.60.100) 126.890 ms 118.628 ms 137.776 ms 9 * * * My Gateway has a default route to the internet and a static route for 44.0.0.0/8 pointing to my WLAN Link to a 'public' Hamnet AP. So what is the point of having sort of a split-brain situation on the 44.0.0.0/8 hamnet ip range? I 'see' ospf packets on the WLAN link, but they only seem announce the local routes withing the swiss part of hamnet, not the global routes. Sort of makes sense, as you probably would run bgp to interconnect the different hamnet as numbers. So do I need to get an own hamnet as number? As a User?!? Or what mechanism is there supposed to be to tell a user which hamnet ip ranges are reachable via internet and which ones are reachable via hamnet. 73 -Benoit- / HB9EUE

Anyone running an open AMPR VPN willing to share?

by David Ranch

Hello Everyone, I'm helping out a local HAM getting an IPIP AMPR setup working but his current AT&T Uverse / Pace s 5862ac unit doesn't seem to be playing nicely. Yeah.. I know.. Shocking! Anyway, touter/NAT mode seems to *only* want to forward TCP/UDP protocols (typical) and it's DMZPlus feature mode seems to be breaking his Wifi network. As we maybe hack with the DMZplus feature tomorrow, I was curious if there is anyone willing to offer up a VPN connection to his Raspberry Pi as a Plab-B: Looking through the archives, there was http://wiki.ampr.org/index.php/AMPRNet_VPN but that link is 404. I know there is also the http://wiki.ampr.org/wiki/AMPRNet_VPN link but I know other HAMs are/were offering less complicated setups. I can help him setup any offering be it IPSEC, SSL-VPN, etc. He's not looking for any sort of performance.. just general IPIP access to play around, etc. at the moment. If already hosting or you're willing to host a solution, let me know. Thanks! --David KI6ZHD

Mikrotik RouterOS script update

by Marius Petrescu

Hello, Mikrotik released its new RouterOS version 6.41, with some changes affecting the gateway script. I released an updated script version to address this issue. For those using pre-6.41 ROS, the update is not necessary. If you want to correct the script manually, just delete the line referring to neighbor discovery disabling in the 'add new tunnel' section of the ampr_gw script whic states: /ip neighbor discovery set $gw discover=no As usual, download at: http://www.yo2loj.ro/hamprojects/ http://yo2tm.ampr.org/hamprojects/ Marius, YO2LOJ

Gateway inside of pfSense DMZ: It WORKS!

by Tom C

Currently running on a Raspberry Pi in a pfSense DMZ on residential Dynamic IP. Marius’ ampr-ripd compiled with no issue, the scripts from my linux gateway that I worked on with Lynwood work perfectly with no modification. Need to do a little tweaking with iptables firewall as my network implementation is different from what it was when I was running one box. Diagram: (Internet)===<pfSense>==(DMZ)==<Raspberry Pi>==(44.98.63.0/29) - I’m NAT forwarding ipip traffic that hits the pfSense external interface to the DMZ (usb NIC) interface on the Pi. - tunnel script and ampr-ripd run on the pi creating tunl0 on the pi - local AMPR segment on the Pi native interface. - pfSense NATs outbound encapsulated traffic making it appear as if it comes from the pfSense box. - My gateways appears on Marius map. Working on documentation for the wiki and will post by weeks end. —tom -- 73 de N2XU/Tom Cardinal/MSgt USAF (Ret)/BSCS/Security+/IPv6 Certified

Re: [44net] Changes afoot on my gateway (Tom Cardinal)

by Luzemário Dantas

Hi Tom, Some tome ago I was fiddling with pfSense to make it my gateway. I abandoned this idea because there was a couple of key issues for me: - BSD needs a device for each IPIP tunnel, this gets the things much more harder to setup; - PfSense does not have the protocols used enabled by default, needing manual edit of the web interface after each update. You have to do it by yourself every time; - Linux has ready made scripts to get the job done. These scripts were made by good hams here and tested by several other people. It is easier to create a small virtual machine and put a 256MB RAM Devuan working than creating a gateway using BSD. - PfSense team is minded to get the commercial way of pfSense as a product, so do not expect any support to get the things working. Their support forum is getting more unconcerned every day. If you are still inclined to use some type of BSD firewall as an AMPRNet gateway, I suggest using OPNSense to start. It was a project forked from pfSense, but today have only 10% of original code and have open source as priority yet. Their forum is much more friendly and responsive. OPNSense has all protocols listed in the web interface, so passing IPIP traffic back and forth is more intuitive (I still would not use it as a gateway anyway). Hope this helps, 73 de PT2LDR Luzemario www.luzehost.com.br Em 06-01-2018 18:00, 44net-request(a)mailman.ampr.org escreveu: > Greetings, > I was working with Dan Cooper last spring to turn my pfSense box into > an ampr gateway.

Changes afoot on my gateway

by Tom Cardinal

Greetings, I was working with Dan Cooper last spring to turn my pfSense box into an ampr gateway. At the time I was trying to learn how IPIP worked AND how BSD (pfSense) worked. I'm pretty well versed in linux... BSD... not so much. At the time I moved to Linux and Lynwood helped me get my head around how the IPIP tunneling works. After seeing the volume of traffic that tries to crack into my residential ISP connection (even though it fails) I've decided to put my ampr gateway into a DMZ. I'm currently in the process of moving my AMPR gateway into a pfSense DMZ. I work in a loosely security related position at work and I'm doing this as a security measure to knock down some of the noise my Linux gateway/Router/Firewall/AMPRgateway was seeing, mostly from Russia, China and other places that I didn't research. My new AMPR gateway will still be on Linux, actually Raspbian on a Raspberry Pi, but the only traffic it'll ever see is encapsulated traffic and traffic from my network because all of the other noise will be filtered by the pfSense box and won't exist in my DMZ. Out of the box the pfSense user interface doesn't have support for ipencap or AX25. I did a little bit of research (google) and found an older post on the pfsense forum about which files to edit to add ipencap and ax25 to the UI. Also, I just asked on the pfSense subreddit to see if there are any other places within the pfSense UI to edit which protocols are available for use. Is anyone else using this method to NAT forward IPIP traffic to an internal gateway (in my case using pfSense). I'm looking to find out if I've missed anything with the port forwarding before I move forward. I know Brian (N1URO) was working with IPIP tunneling behind a NAT and I think (THINK) this might work. So... here's what I've done. pfSense version is 2.4.2p1. File edits follow... In file: /usr/local/www/firewall_nat_edit.php On line 708, change: $protocols = "TCP UDP TCP/UDP ICMP ESP AH GRE IPV6 IGMP PIM OSPF"; To: $protocols = "TCP UDP TCP/UDP ICMP ESP AH GRE IPV6 IGMP PIM OSPF IPENCAP AX25"; In file: /usr/local/www/firewall_nat_out_edit.php On line 510, change: $protocols = "any TCP UDP TCP/UDP ICMP ESP AH GRE IPV6 IGMP carp pfsync"; To: $protocols = "any TCP UDP TCP/UDP ICMP ESP AH GRE IPV6 IGMP carp pfsync IPENCAP AX25"; In file: /usr/local/www/firewall_rules_edit.php Insert as line 1315 and 1316: 'ipencap' => 'IPENCAP', 'ax25' => 'AX25', -- Tom / n2xu / MSgt USAF (Ret) / BSCS, CASP

Re: [44net] Mikrotik RouterOS script update

by Rob Janssen

> You can, but please do not. > It will enable neighbor discovery on new tunnels, which is not desired > and creates useless traffic. > There are no functional changes except this. > Marius, YO2LOJ When researching this matter (I wanted to enable neighbor discover on new L2TP tunnels internal to our network) I found that this command line can disable it by default: /ip neighbor discovery settings set default=no default-for-dynamic=no The "default" is for manually created interfaces like IPIP tunnels, the "default-for-dynamic" is for dynamic interfaces like the server-side of L2TP tunnels. With this command issued once, the discovery should be off on new tunnels on versions < 6.41 However, this command no longer exists in 6.41 ! Now, setting of discovery is done using an interface list with the members of the list participating in discovery (or the non-members, there is an inversion operator) So look in the "ip neighbor" discovery settings to see how the interfaces are now set, there can be an interface list "discover" (the new default) or there can be something like "!dynamic" which results in discovery on all non-dynamic interfaces (the old default). When it says "!dynamic" it is better to change that to "discover" and put only your local interfaces in that list. Rob

retirement

by Brian Kantor

I am retiring from UCSD, after 47 years on campus. My new mailbox is brian _AT_ bkantor.net. Future emails from me will usually come from there, although some may come from my @ucsd.edu address for the next few weeks as I transition various functions to the new mailbox. The old UCSD address will forward to it for a while. I will continue to use the @ampr.org address for some AMPRNet and ARDC business. Amprgw (gw.ampr.org) will continue to operate as it has for some time as part of the CAIDA research group continuing measurement and analysis of dark networks project. No changes in its operation are planned. I will still be managing the amprnet-related portions of the amprgw system, and AMPRNet in general, as before. This mailing list will not be affected, as it is not hosted at UCSD. - Brian

GW Setup Problem

by Barış DİNÇ

Hi All, I am sure that this question is asked by many newbies but I have to ask it to bring up my gateway... :) I set up a gateway and coordinated the ip allocation with my regional IP coordinator. But, however, testing behind NAT or without NAT (directly machine connected to internet (a server on a colaction ISP)) didn't have success.. using ampr-ripd with compiled DEBUG options I cant get and response from the 44.0.0.1 For testting I just did # ifconfig tunl0 up 44.176.200.1 netmask 255.255.255.255 and tried #./ampr-ripd -d -v -i tunl0 the result is as follows but no success even if I wait for 2 hours... IS THERE A WAY TO TEST THIS RIPD CONNECTION ? (a tool or sniffing with tcpdump..) HOW CAN I BE SURE THAT I AM DOING EVERTHING RIGHT ?

CalAmp Viper SC+

by Michael Fox - N6MEF

All, I've been looking for a way to get fast enough speed over RF to be able to use some more modern protocols, such as SMTP & POP3 for email with attachments. I had high hopes for some guys in the NW US, but . <sigh>. So, I started looking elsewhere and someone else here mentioned the DataRadio -> CalAmp Gemini. That particular radio was recently discontinued. But I found the CalAmp Viper SC+. There are several models. It can achieve up to 256 kbps, depending on band, channel configuration, etc. We would probably use the radio in the 70 cm band. My assumption was that any emission designators that they might use would most likely not be allowed in FCC Part 97. But they use emission designators .F1D. And what does FCC Part 97 say? 97.305(c): For the 70 cm band, it references 97.309(f)(6) and 97.309(f)(8). 97.309(f)(8): "A RTTY or data emission having designators with A, B, C, D, E, F, G, H, J or R as the first symbol; 1, 2, 7, 9 or X as the second symbol; and D or W as the third symbol is also authorized." How about that!? ...F1D fits that bill. Baud rate is also within FCC limits. So this looks like a real possibility. Price is steep: about $1400 list. But for our purposes, it fills a gap between 1200/9600 packet and WiFi, allowing for field deployment with a simple roll-up J-pole. And provides locations some basic IP connectivity even if they don't have line of sight for WiFi. If you're interested, check it out! BTW, for you non-US guys, they have international certifications. Check out the details via a local distributor. http://www.calamp.com/products/cellular-communication-devices-routers/router s/viper-sc-0 http://www.calamp.com/system/files/resources/hardware-spec-sheets/viperscplu sdatasheet.pdf http://www.calamp.com/references/manuals/Viper_SC_User_Manual.pdf Michael N6MEF

Master DNS server for AMPR.ORG and 44.IN-ADDR.ARPA upgraded

The master DNS server for AMPR.ORG and 44.IN-ADDR.ARPA on gw.ampr.org has been upgraded from ISC bind9.10 to bind9.11. (FreeBSD maintenance of 9.10 is ending in a few months.) This should not affect anyone. Let me know if you suddenly encounter any host or address lookup problems from today on. - Brian

misconfigured gateways

by Brian Kantor

There are two gateway systems with misconfigured routing tables that are attempting to route all of net44 through amprgw instead of using mesh connections. These may have a default route instead of using the correct routing table. Whatever the case, they aren't going to have much luck reaching other net44 hosts. Those gateway operators should check their configurations. - Brian Last update at Sun Oct 22 06:30:01 2017 PDT [-0700] gateway inner src #errs indx error type ---------------- ---------------- ----- ---- ------------------------------- 79.0.254.164 44.134.96.1 5408 [ 8] dropped: encap to encap 173.230.244.130 44.68.41.1 1349 [ 8] dropped: encap to encap

44net gateway downstream routing

by Pedro Ribeiro

Hello, I've mapped 2 blocks ( 44.158.128.0/20 & 44.158.158.0/23 ) in the AMPR portal, to the gateway 193.137.237.9 Both blocks have the "Tunnel" checkbox active. When I generate traffic from the Internet to the IP 44.158.128.1 I can see some encapsulated (IPoIP porto 4) arriving but when the target is 44.158.158.1 (or any other IP from the 2nd IP block) no traffic arrives.

AMPRnet Allocation for a Club?

by Michael Casadevall

Greetings all, I'm working on helping renovating a repeater system for the Southern Catskill Amateur Radio Society (KC2AXO - http://wireless2.fcc.gov/UlsApp/UlsSearch/license.jsp?licKey=421389), and was interested in figuring out the rules for getting an AMPRnet assignment for the club. I'd like to get a /24 though we could probably work with smaller as long as it's a large enough allocation to subnet it. Right now, we have a simple 2m repeater, but we're building two 33cm links up to the repeater shack to get connectivity up there. Right now, we're interested in setting up EchoLink/IRLP/AllStar for the repeater, and pending a second antenna/additional equipment, possibly a digipeater, APRS gateway, and packet BBS. Right now, we've got three sites (the primary repeater, a fill-in site, and the base station in town). The rough plan right now is as follows: - svxlink up at the shack for repeater control - 33cm downlinks to the fill-in repeater/club station - svxlink instance in the club which terminates traffic going to the internet (this acts as a Link Station, and keeps us within Part 97 compliance w.r.t Internet traffic and RF links) - aprsd running on the repeater, direct connection to APRS-IS (since this is all ham-to-ham traffic with callsigns, this should be legal per Part 97). - As resources allow, RF link to AMPRnet in general We'll have to get gateways to the other AMPR networks like HamWAN and such for 44net traffic to be reachable elsewhere. What I'd like to do is use an AMPRnet allocation from our base station, and then pipe service up to the repeater via a second fill-in site we have. AMPRnet seems like a logical way to do this, and as we expand the club, also allow folks to play with packet radio. I looked through the archives and the wiki and saw nothing about club allocations for AMPRnet so I figured I'd try here before filling out the application form as well as getting suggestions from the 44net community. I'm not the trustee (N2TDX) for the club sign, but I'm acting w/ his permission and can have him do the registration process if need be. Just trying to figure out the process and get our feet wet with AMPRnet. 72 de KD2JRT

[44-announce] amprgw OS upgrade Sunday

by Brian Kantor via 44-announce

I'm currently planning to upgrade the operating system and packages on amprgw (aka gw.ampr.org) Sunday morning Pacific time. This will take the system from FreeBSD 10.3-RELEASE to 11.1-RELEASE, since the 10.3 version will be going end-of-life in early 2018. There will be a few times where the system will be out of service while it reboots. Each time, you may notice that packet forwarding is briefly not working. - Brian -- 44-announce mailing list 44-announce(a)mailman.ampr.org https://mailman.ampr.org/mailman/listinfo/44-announce

Wireless security flaw revealed

by Brian Kantor

This appears to be somewhat serious; it will probably require people to reflash the firmware in some or all of their wireless devices when fixes become available. How one reflashes IoT devices is problematic. - Brian From ARSTechnica: "The proof-of-concept exploit is called KRACK, short for Key Reinstallation Attacks. The research has been a closely guarded secret for weeks ahead of a coordinated disclosure that's scheduled for 8 a.m. Monday, east coast time. An advisory the US CERT recently distributed to about 100 organizations described the research this way: "US-CERT has become aware of several key management vulnerabilities in the 4-way handshake of the Wi-Fi Protected Access II (WPA2) security protocol. The impact of exploiting these vulnerabilities includes decryption, packet replay, TCP connection hijacking, HTTP content injection, and others. Note that as protocol-level issues, most or all correct implementations of the standard will be affected. The CERT/CC and the reporting researcher KU Leuven, will be publicly disclosing these vulnerabilities on 16 October 2017." https://arstechnica.com/information-technology/2017/10/severe-flaw-in-wpa2-…

Re: [44net] Firewall logs settings recommendations

by Rob Janssen

> I get a screen ful of garbadge because most of it are fail login attempt and then i can not see any usefull info because the garbadge is so big it cover the few line of real info i want to see It is not a good idea to have the admin interface of your router open to the entire internet. Fix that using the input chain of the firewall, and the messages will be far fewer. Of course you may also want to limit what the router forwards to systems behind it, depending on your network config. Rob

Firewall logs settings recommendations

by R P

Hi there I have a Mikrotik for the 44 net It have a firewall and currently it logs to the screen and the ram (not to the disk) any fail login ... and some rules (not too much as i want open network) such as SIP signals that are many and some other big intruders protocols Now i have some deliberation (i hope it is the right word i used google translate) how to configure the logs ? I get a screen ful of garbadge because most of it are fail login attempt and then i can not see any usefull info because the garbadge is so big it cover the few line of real info i want to see I wanted to change the log rules that only successful login will be logged so i will not see so much traffic .. but then i will not see the break in attempt and might loose real break in currently i check the fail login and im more aware so if i see a raise in login failures i check the reason and even make rule to block the IP im afraid when i will rely only on logging the successful logins it might be too late when i will discover that someone have already logged in to the system Indeed ist not a top secret router and network behind it its only ham radio // but still ... Is there are experts here that might tell me what is the best way to do ? when i was long ago sys admin i followed a rule that said what you dont look at you dont know what is going on behind but the garbage info today is so big that it require hours to real look at it Regards Ronen - 4Z4ZQ

Ok so i sent off to get a /24 however the statement that came back to me was i need to put this under IL so my question is... Is this because i live in IL or because you think i will be routing this from all from IL.. I own several servers around the country I rent and release servers all the time.. I have currently servers in Canada, London and just shut down one in Dallas Texas so what i am trying to say is that all ip's may not be pointed to IL all the time is this an issue? I guess i am kinda confused as to why under IL.. Here is the message. Request rejected.

Allocation change

by Mike Vespoli

Since we are talking about it. I had previously requested a subnet and was approved. I originally thought I was going to have to do an IPIP tunnel but I was able to get my ISP to advertise the route. I went to the allocation section on my portal and checked the box under Direct. Do I need to do anything else? The ticket hit the queue at my ISP and they are just waiting for authorization. I was hoping to get the new firewall installed on November 4th. Thanks for all of your help. I personally like how helpful and informative everyone is. Mike Vespoli KE0HFH

RFC2468 - Remembering Oct 16, 1998

by Brian Kantor

Network Working Group V. Cerf Request for Comments: 2468 MCI Category: Informational October 1998 I REMEMBER IANA October 17, 1998 Status of this Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Copyright Notice Copyright (C) The Internet Society (1998). All Rights Reserved. Remembrance A long time ago, in a network, far far away, a great adventure took place! Out of the chaos of new ideas for communication, the experiments, the tentative designs, and crucible of testing, there emerged a cornucopia of networks. Beginning with the ARPANET, an endless stream of networks evolved, and ultimately were interlinked to become the Internet. Someone had to keep track of all the protocols, the identifiers, networks and addresses and ultimately the names of all the things in the networked universe. And someone had to keep track of all the information that erupted with volcanic force from the intensity of the debates and discussions and endless invention that has continued unabated for 30 years. That someone was Jonathan B. Postel, our Internet Assigned Numbers Authority, friend, engineer, confidant, leader, icon, and now, first of the giants to depart from our midst. Jon, our beloved IANA, is gone. Even as I write these words I cannot quite grasp this stark fact. We had almost lost him once before in 1991. Surely we knew he was at risk as are we all. But he had been our rock, the foundation on which our every web search and email was built, always there to mediate the random dispute, to remind us when our documentation did not do justice to its subject, to make difficult decisions with apparent ease, and to consult when careful consideration was needed. We will survive our loss and we will remember. He has left a monumental legacy for all Internauts to Cerf Informational [Page 1] RFC 2468 I REMEMBER IANA October 1998 contemplate. Steadfast service for decades, moving when others seemed paralyzed, always finding the right course in a complex minefield of technical and sometimes political obstacles. Jon and I went to the same high school, Van Nuys High, in the San Fernando Valley north of Los Angeles. But we were in different classes and I really didn't know him then. Our real meeting came at UCLA when we became a part of a group of graduate students working for Professor Leonard Kleinrock on the ARPANET project. Steve Crocker was another of the Van Nuys crowd who was part of the team and led the development of the first host-host protocols for the ARPANET. When Steve invented the idea of the Request for Comments series, Jon became the instant editor. When we needed to keep track of all the hosts and protocol identifiers, Jon volunteered to be the Numbers Czar and later the IANA once the Internet was in place. Jon was a founding member of the Internet Architecture Board and served continuously from its founding to the present. He was the FIRST individual member of the Internet Society I know, because he and Steve Wolff raced to see who could fill out the application forms and make payment first and Jon won. He served as a trustee of the Internet Society. He was the custodian of the .US domain, a founder of the Los Nettos Internet service, and, by the way, managed the networking research division of USC Information Sciences Institute. Jon loved the outdoors. I know he used to enjoy backpacking in the high Sierras around Yosemite. Bearded and sandaled, Jon was our resident hippie-patriarch at UCLA. He was a private person but fully capable of engaging photon torpedoes and going to battle stations in a good engineering argument. And he could be stubborn beyond all expectation. He could have outwaited the Sphinx in a staring contest, I think. Jon inspired loyalty and steadfast devotion among his friends and his colleagues. For me, he personified the words "selfless service". For nearly 30 years, Jon has served us all, taken little in return, indeed sometimes receiving abuse when he should have received our deepest appreciation. It was particularly gratifying at the last Internet Society meeting in Geneva to see Jon receive the Silver Medal of the International Telecommunications Union. It is an award generally reserved for Heads of State, but I can think of no one more deserving of global recognition for his contributions. While it seems almost impossible to avoid feeling an enormous sense of loss, as if a yawning gap in our networked universe had opened up and swallowed our friend, I must tell you that I am comforted as I contemplate what Jon has wrought. He leaves a legacy of edited documents that tell our collective Internet story, including not only Cerf Informational [Page 2] RFC 2468 I REMEMBER IANA October 1998 the technical but also the poetic and whimsical as well. He completed the incorporation of a successor to his service as IANA and leaves a lasting legacy of service to the community in that role. His memory is rich and vibrant and will not fade from our collective consciousness. "What would Jon have done?", we will think, as we wrestle in the days ahead with the problems Jon kept so well tamed for so many years. There will almost surely be many memorials to Jon's monumental service to the Internet Community. As current chairman of the Internet Society, I pledge to establish an award in Jon's name to recognize long-standing service to the community, the Jonathan B. Postel Service Award, which will be awarded to Jon posthumously as its first recipient. If Jon were here, I am sure he would urge us not to mourn his passing but to celebrate his life and his contributions. He would remind us that there is still much work to be done and that we now have the responsibility and the opportunity to do our part. I doubt that anyone could possibly duplicate his record, but it stands as a measure of one man's astonishing contribution to a community he knew and loved.

Indeed that is a big mistake :-) But it is good that you know that and so you can take countermeasures. Normally after a couple of days this flood will stop, although there is always some remaining noise from other kinds of DDoS. E.g. systems on internet sending a DNS request like that to a resolver they want to attack, with (one of) your address(es) as the source. The resolver will send back the large "reply" to your system and there is nothing that can be done about it. The source address of the packets is the system under attack, and it is no use sending an abuse message to them because they cannot do anything either (except blocking DNS requests from 44.x.x.x addresses, but that could result in "problems" for legitimate users in our network). This problem can only be solved by widespread adoption of BCP38 (source address filtering), and the takeup is slow. Anyway, when configuring your firewall make sure you have a "default deny" policy and allow only the protocols that you know you are using. This is especially true for UDP. e.g. SNMP (UDP port 161) is another attack vector similar to what you have seen now. Don't allow SNMP from the internet. Best is to allow only what you really need, and for protocols like NTP (UDP 123) make sure that it is correctly configured so that it only does time replies to internet addresses and does not allow queries except from the local network. (queries can return much more data than the size of the query packet so they are used in amplification attacks, time replies are the same size as the request) Rob

DDoS via net44

by Pedro Ribeiro

Hello everyone, I'm creating a gateway here, to be used to static and dynamic VPNs to Portuguese HAMs trying to access the 44net. I've noticed that after I've leaven the router a few days with the DNS relay open (big mistake!), I was receiving a stream of dummy querys about a hundred per second. I was able to block it in our (Lisbon Polytechnics) firewall (before ipip de-encapsulation) with the next iptables rule: # iptables -t raw -A PREROUTING -i eth0 -p ipencap -d 193.137.237.9 -m length --length 87 -m u32 --u32 "42 = 0x0035002f" -j DROP Now I've disabled the gateway at the AMPR portal and I'll wait for them to calm down. I don't know if more tunnels are affected by this so I'm sharing the information. tcpdump output at the firewall: > 10:24:57.864885 IP 169.228.34.84 > 193.137.237.9: IP > 101.173.185.122.17596 > 44.158.128.1.53: 46623+ [1au] ANY? activum.nu. > (39) (ipip-proto-4) > 10:24:57.864886 IP 169.228.34.84 > 193.137.237.9: IP > 101.173.185.122.17596 > 44.158.128.1.53: 46623+ [1au] ANY? activum.nu. > (39) (ipip-proto-4) > 10:24:57.864888 IP 169.228.34.84 > 193.137.237.9: IP > 101.173.185.122.17596 > 44.158.128.1.53: 46623+ [1au] ANY? activum.nu. > (39) (ipip-proto-4) > 10:24:57.864889 IP 169.228.34.84 > 193.137.237.9: IP > 101.173.185.122.17596 > 44.158.128.1.53: 46623+ [1au] ANY? activum.nu. > (39) (ipip-proto-4) > 10:24:57.864929 IP 169.228.34.84 > 193.137.237.9: IP > 101.173.185.122.17596 > 44.158.128.1.53: 46623+ [1au] ANY? activum.nu. > (39) (ipip-proto-4) > 10:24:57.864931 IP 169.228.34.84 > 193.137.237.9: IP > 101.173.185.122.17596 > 44.158.128.1.53: 46623+ [1au] ANY? activum.nu. > (39) (ipip-proto-4) > 10:24:57.864933 IP 169.228.34.84 > 193.137.237.9: IP > 101.173.185.122.17596 > 44.158.128.1.53: 46623+ [1au] ANY? activum.nu. > (39) (ipip-proto-4) > 10:24:57.864934 IP 169.228.34.84 > 193.137.237.9: IP > 101.173.185.122.17596 > 44.158.128.1.53: 46623+ [1au] ANY? activum.nu. > (39) (ipip-proto-4) > 10:24:57.864936 IP 169.228.34.84 > 193.137.237.9: IP > 101.173.185.122.17596 > 44.158.128.1.53: 46623+ [1au] ANY? activum.nu. > (39) (ipip-proto-4) > 10:24:57.864937 IP 169.228.34.84 > 193.137.237.9: IP > 101.173.185.122.17596 > 44.158.128.1.53: 46623+ [1au] ANY? activum.nu. > (39) (ipip-proto-4) > 10:24:57.864938 IP 169.228.34.84 > 193.137.237.9: IP > 101.173.185.122.17596 > 44.158.128.1.53: 46623+ [1au] ANY? activum.nu. > (39) (ipip-proto-4) > 10:24:57.864940 IP 169.228.34.84 > 193.137.237.9: IP > 101.173.185.122.17596 > 44.158.128.1.53: 46623+ [1au] ANY? activum.nu. > (39) (ipip-proto-4) > 10:24:57.864941 IP 169.228.34.84 > 193.137.237.9: IP > 101.173.185.122.17596 > 44.158.128.1.53: 46623+ [1au] ANY? activum.nu. > (39) (ipip-proto-4) > 10:24:57.864943 IP 169.228.34.84 > 193.137.237.9: IP > 101.173.185.122.17596 > 44.158.128.1.53: 46623+ [1au] ANY? activum.nu. > (39) (ipip-proto-4) > 10:24:57.864944 IP 169.228.34.84 > 193.137.237.9: IP > 101.173.185.122.17596 > 44.158.128.1.53: 46623+ [1au] ANY? activum.nu. > (39) (ipip-proto-4) > 10:24:57.864945 IP 169.228.34.84 > 193.137.237.9: IP > 101.173.185.122.17596 > 44.158.128.1.53: 46623+ [1au] ANY? activum.nu. > (39) (ipip-proto-4) 73! -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Callsign: CT7ABP QRA: Pedro Ribeiro GRID Locator: IM58mr QTH: São Francisco, Alcochete, Portugal NET: http://www.qrz.com/db/CT7ABP CT7ABP is also home station of CR7AJI Diogo =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

greylisting on mailman (this list)

by Brian Kantor

I've turned off greylisting on mailman.ampr.org as it seemed to be causing more trouble than it was fixing. We'll just have to see how bad the spam problems get, and may have to turn it back on again sometime down the road. In the meantime, mail to the mailing list should no longer be delayed by greylisting requiring senders to retry delivery. - Brian

behind nat

by Steve L

Alright just when you think you are a pro, I am a bit puzzled: I am trying to deploy a new gateway. The router runs tomato shibby firmware with DMZ pointed to 192.168.1.44, the ampr-gw. When I run tcpdump I see the rip announcements and my route table is populating, but I don't see my test pings, etc coming from the general internet (and there is a dns entry) Do you have to set a special ip rule vs if the wan interface is an outside IP. I have a tried a few things that I thought made sense with no luck. Could someone who is also behind nat share their start script with me? I guess I need to build a gateways with different hardware more often.
