- 44net - mailman.ardc.net

by kb9mwr＠gmail.com

I was going to run a pipermail email list on a 44 IP. While I am sure I can get it to work fine between other 44 hosts, my guess is that it will see little use if I can't make it work like any other host on the wide internet. The latest problem again is with outside connectivity. There seems to be some sort of TTL issue going on. My network /host isn't always reachable from the internet. And it seems to depend on who you are using for internet. My host: 44.92.21.35 Seems to work fine from a time warner cable connection in Green Bay. But other people report not being able to reach it. Looking at other 44net hosts connected to the internet: pinging 44.88.0.9 - Fine pinging 44.4.92.50 yes but with packet loss So it turns out a lot of my SMTP headaches track back to this bigger problem.

- Are you willing to establish an email server and be willing to maintain it? - Who would be responsible for maintaining the accounts? - Do you have a privacy policy in place? - What is your ISP's bandwidth limit? - Do you have the facilities to backup and store emails for all users? - The same DNS entries would be required, and the ampr.org domain (or subdomain) would have to be the only one used. -KB3VWG > At the very least shouldn't AMPRnet folks be able to send and receive > email from other AMPRnet stations?

Steve, I have ran mail servers, but I do not currently run one on AMPRNet; my last attempt was to setup a home server was an IPv6-only server for the purposes of passing a certification exam. There are many reasons for not maintaining it (some of which may be why you're having issues, hope this helps): - The domain you're using for email must have an MX record - That MX record must point to a valid A Record (it doesn't have to be the same domain) - Your mail server must be configured with the hostname name noted in the A Record - The IP noted in the A record must have a PTR record that returns the same hostname in the A Record (this can only be done by one of our friendly Brians, this has to be done in 44.in-addr.arpa) also make sure that - you have configured the SMTP server to receive email for the domain in which you created a global MX record entry - make sure that email account exists on the server - if it is multi-homed, make sure the gateway/default route is over 44NET While mail servers should work with the first two, many ISPs configure their servers only to "talk" with mail servers who also have the PTR record in place. -Lynwood KB3VWG

Thanks for the explanation Tim. I haven't messed with running a mail server since 1999 so a lot has apparently changed, and I am a bit concerned about doing it right. Presently I am trying trying exim on a CentOS platform. It seems to send out mail just fine, but when it comes to answering someone else connecting to it from the general internet that is were I apparently don't have something configured right yet. Anyone care to create a nice write up :-)

Re: [44net] SMTP port 25

I found that Comcast only blocks "Residential" subscribers from port 25. The minute I upgraded to a "Commercial" account, all restrictions were removed. The best part was that for a commercial account with one dedicated IP address, it was cheaper than the residential service was. Not sure this approach will work for all though.

Turns out you have to specify the interface address for sendmail to respond to, 127.0.0.1 is default so that is why that always worked.

SMTP port 25

by kb9mwr＠gmail.com

Is anyone running a SMTP server on their gateway? Most ISP's block port 25 outgoing, the problem I am seeing. I see a email handshake come in and forward over the wireless LAN, But when it comes from a non 44 IP is tries to reply using my assigned ISP provided IP and obviously that doesn't work. So is there some way with IP tables or something else to set and advanced IP rule where is it's a destination on port 25 to route thru amprgw.sysnet.ucsd.edu using my 44 address?

testing for source address filtering....

by Eric Fort

Occasionally I have access to 2 Verizon DSL connections in the same location. the connections while being the same provider are generally a dynamic IP from different /24 subnets and there's about 4 hops between them. (once they reach a common point a couple hops away all other traceroute data is the same. how can I test to see if one connection filters source addresses belonging to the other? (and any guesses as to what the results may be?) Eric

The system is running Debian Wheezy, all uptodate, with bind9 version 9.8.4 plus Debian patches. It is not available to the outside no so security worries. What I see is that it does not cache ampr.org addresses very long, but that does not surprise me because the default TTL in the zone is only one hour. Of course everything would perform better when the TTL was the more usual 24hours, but undoubtedly there was a good reason to set this TTL. (lately it was useful for me as I changed the external address of the machine and the update was propagated quickly in DNS, but in general I would think the zone is very static) What I am surprised about is that the measured relative performance of the 7 alternative DNS servers is apparently not kept by bind long enough to be useful. The TTL at that level is 24 hours but I think I have often seen that when doing the same lookups within 24 hours I see lookup delays again. The statistics command you gave does not provide that info, I wonder if there is some bind command to query its measured timers and preferred servers. We have several timeservers on net-44 addresses and I do "ntpq -p -c rv -c mrulist" a couple of times a day now that we are testing and deploying. It was slow every time, of course the cached lookups are gone because the previous try was more than an hour ago, but apparently the DNS preference info was gone too and queries were again sent to slow (for me) servers. After my experimental change with the hardwired forwarders everything works much better. I'm not sure I want to keep it, but it certainly indicates that there *is* a way in which bind could handle it more efficiently. Maybe I am missing some setting, I have experimented with setting a forwarder (and forward first) at top level as well. Probably I should turn off the DNSSEC that has been enabled by default by bind and Debian, that appears to cause a lot of extra overhead too. Rob

New services idea.

by kb9mwr＠gmail.com

First, Lynwood thanks for sharing PHP code snippet. Does anyone know much about google maps? More than 15 years ago a younger local ham friend of mine wrote some web based interactive tools for wireless link planning. Maybe you have run into them: http://n9zia.ampr.org/ This isn't presently on 44-net. I have just been using the ampr dns to give it a hostname that has been pointing to my home cable modem for a long time now. They run horribly slow (same computer for 15 years and slow upload speed) I'd love to see these tools freshened up a bit to use PHP, and possibly integrate google maps. Neither the original author, Joe N9ZIA or myself really have a lot of experience with either. But we are both surprised someone hasn't already done this. Just throwing the idea out there for anyone who would like a project, the code is open under GPL. The tools help promote modern RF network planning. After a rewrite perhaps they could be hosted on a 44 IP, and put a paypal please donate nag screen if you come in from a commercial IP. The paypal proceeds can go to helping ARDC with Brian's ok.

Re: [44net] Performance of DNS

by Rob Janssen

More tracing reveals why the times are sometimes as high as I reported... It first got my attention because commands like "netstat -t" and "ntpq -p" took quite some time to execute when 44.x.x.x addresses were in the listing, stopping for each reverse lookup. I had also noticed that "ping callsign.ampr.org" always takes some time before it sends the first ping. So I decided to investigate. I used this command to time it: time host callsign.ampr.org It appears that when the callsign exists, this does two lookups, for the A and MX record. When the callsign does not exist (I also tested that), it also does two lookups: the specified one, and the one with .ampr.org appended a second time. This is caused by "search ampr.org" in /etc/resolv.conf. It was put there by the Linux installer, I know many Linux distributors do that. (you specifiy a hostname and domainname during install, and it will put the domainname in /etc/resolv.conf as a search line) That explains the long execution time of "host" that could not be explained by a single lookup. I think it is not very clever of the resolver library to append a search domain that already was in the query, but maybe there are some cases where this is useful? Anyway, I removed that from resolv.conf as this machine is not for end-users anyway, and I don't mind typing full domain names. It doubles the speed of all lookups of nonexisting names, and reduces the load on the ampr.org nameservers as well. This doubles the speed of the host command, but of course the reverse lookups are not affected. When using those two local DNS servers first, they are fast. Bind should learn and remember that, I think. It is only good that ampr.org DNS servers are around the globe, and a pity that bind does not take that to an advantage. It does do that for forwarders, at least that is written in the docs. (this machine runs bind as a caching resolver and the nameserver in resolv.conf is 127.0.0.1) Rob

Of course it is on the other end of the world, the pingtime is 350ms. The lookup of org and ampr (when not in cache) also take 300ms each, so in total a lookup takes quite some time. When I trick the whole thing using these bind9 zones in my local caching resolver: zone "ampr.org" IN { type forward; forward first; forwarders { 192.109.42.4; 195.66.148.101; }; }; zone "44.in-addr.arpa" IN { type forward; forward first; forwarders { 192.109.42.4; 195.66.148.101; }; }; everything is very very fast. of course this is to be expected, as the tree lookups are no longer required and the fastest (for me) servers are used first. But of course it is a dirty trick, and it will fail when those servers change address. It looks like bind does not remember performance of DNS servers as it does for forwarders, or when it does it may have forgotten that info by the time it is required again and therefore does not use only the fastest servers?

seeking recommendations for VPN capible (home) router

by Eric Fort

I'm presently seeking recommendations for a consumer grade home router that will work as both a vpn client and vpn server for PPTP, L2TP, OpenVPN, and IPSEC protocols. support for plain GRE would be useful as well. the router should be easy to configure with a fill in the boxes and check marks type web interface. Ideally an unlimited number of VPN tunnels would be supported along with support for RIP and OSPF. what does this list know of that comes at least close to this? Eric AF6EP

Performance of DNS

by Rob Janssen

I often experience relatively slow lookups of DNS records in .ampr.org and 44.in-addr.arpa. Not every time, but lookup times of 2-3 seconds occur quite often, especially for the first one in a series (the TTL in the zones is only an hour, so there is little caching). 44.in-addr.arpa also sometimes fail for existing hosts, to succeed when they are re-tried later. Do other people see this? It looks like there are 7 DNS servers, which seems to be plenty. Are they overloaded? Do we need or like to have more DNS servers? Should I volunteer to provide one? Or could there be another reason for this phenomenon? Rob

Please note that there is no relation whatsoever between announcing via BGP and offering an OpenVPN or other VPN access instead of IPIP tunnels. Those are two completely ortogonal subjects. It is possible to setup an OpenVPN or other VPN access on a gateway that is connected to others via IPIP tunnels, that is what I have now. And it is possible to have a BGP announced gateway that does not offer OpenVPN. And it is possible to combine the two. You can setup an OpenVPN access system that operates as a normal IPIP gateway on any of the low-cost virtual servers that you can get everywhere today. No need for ISP cooperation or BGP routing. Just get a Linux virtual server, install a couple of packages, configure them, and there you go. Rob

That is not finished (waiting for permission from the ISP and then from ARDC), but it already operates as a gateway. On that machine I installed the OpenVPN server. So it only works for existing adresses in the 44.137.0.0/16 network, that are not within a subnet registered at the portal. However, others have taken a different approach, they allocate new addresses from a special subnet. I think the Finnish server does this as well. Best would be if someone nearer to you provides this service, as this yields much better performance. Rob

Here in the Netherlands I have just setup an OpenVPN server that can be used for this for addresses within 44.137.0.0/16. Anyone with such an address can just mail me and I'll send them a certificate and example config file. I plan to enable PPTP, L2TP/IPsec and IPsec as well as demand arises. There is an OpenVPN service in Finland as well, see http://wiki.ampr.org/index.php/AMPRNet_VPN I think they are open for registration from anywhere (not just Finland). Of course best is when you start a server in your own area. Rob

When I do a traceroute to 44.140.128.7 from a system behind that router, I can see that the packets come in via ethernet and they are forwarded to the IPIP tunnel interface for 44.140.0.1, however the Mikrotik router never sends any IPIP packets out via my upstream ethernet connection. When I add the following route: 4 A S dst-address=44.140.0.1/32 gateway=46.29.182.225 gateway-status=46.29.182.225 reachable via ether10 distance=1 scope=30 target-scope=10 are actually sent out of the ethernet to the upstream. However there is no response from 44.140.0.1 in any case. (There is a possible work around by using different routing tables, but depending on the type of rules, this could still have the same effect.) I'm not very sure how this can be solved, eventually by announcing 44.140.0.0/24 via commercial BGP. Any ideas are welcome. 73 de Marc, LX1DUC

44net and internal BGP tests

by lx1duc＠laru.lu

Good afternoon, just to let you know, we are testing a new BGP setup between our 44net routers. (This has *nothing* to do with a BGP connection to the internet!!) As the 1023 16-bit ASN numbers are in use mostly in DL and surrounding countries, we were looking for another larger ASN space. The logical alternative is the 32-bit ASN space. The ASNs 42XXXXXXXX are reserved for private use by IANA (except the last ASN!). In order to avoid potential collisions we intend to use the ASNs 42270XXXXX in LX. 270 is the MNC (E.212) for LX (with some inspiration from DMR). We will soon publish the exact ranges in use and I will publish the URL here asap. If anybody of you is already using ASNs from the ranges mentioned above, please let me know. Nothing is written in stone, so we can still rearrange our setup HI :-). If someone of you is interested to setup a BGP session on the existing IPIP tunnel or on a dedicated IPIP, GRE, ... tunnel, please also get in touch with me. We are currently running the following services in our 44net: - 2 DMR repeaters - several D-Star HotSpots - DNS resolvers open to 44net (Anycasted), secondary DNS Service available for fellow YLs and OMs - NTP servers (Anycasted) - VoIP (SIP) and Jabber (XMPP) server - VPN - (planned) APRS Server - (planned) connect existing APRS I-GATEs - (planned) Hosting of HAM webs - (planned) Hosting of HAM email services 73 de Marc, LX1DUC

IPIP with pfSense Firewalls

by Rod Ekholm

I have set up a new firewall for my network, and am wanting to use it to also perform either the encap.txt updates, or even a few isolated IPIP tunnels to get my connections back to the 44/8 network. Is anyone else running pfSense to do this? I would be interested in some help in making this work. Screenshots, a write up.. Anything!!! I'll explore it more today for a bit, but I'm still baffled by some of the way pfSense does things and still trying to figure it out. Thanks for any help you can offer! -- Rod Ekholm kc7aad(a)gmail.com

tunl0

by gm4upx＠gb7jd.co.uk

Hello, While waiting for my allocation to be actioned and having little or no experience I decided to experiment to learn more about the use of the tunnel interface and what would be possible with it. I have all ports forwarded from my ISP's modem to a PC I am using as a router. I have a tunnel set up on a one to one basis with a forwarding partner and it works well. My router PC has three network cards, one with a 192.x.x.x/24 address and the other two with a 44.x.x.x/29 and 44.x.x.x/27 address. Connections between both 44.x.x.x addresses work with my forwarding partner and I can forward between my 44.x.x.x addresses using [ eth0 ] but not when I set the route at each via [ tunl0 ]. Is it something simple I have missed ?? Regards, Ian..

New member - VE5EIS

by Jim MacKenzie

Hi all, Just joining the list... I applied for a 44net subnet last week and am beginning the steps to do something cool and interesting with this. I'm a new ham as of April 2013 (VE5EIS) and work on both VHF/UHF and the HF bands. I also am involved with a hobby project in Canada called the Metanetwork, where we link disparate networks together and learn about networking, route advertising, and so on. The project has gotten me to learn about all sorts of useful networking things such as using OpenVPN and deploying IPv6. My routers and my most interesting computers run Linux or BSD. I'm hoping to learn more about packet radio and deploy some RF hops on my subnet. I have some ideas of some useful projects that could be done, e.g. UUCP over RF for email links between sites that don't have Internet or telephone connectivity. At this point I'm working on getting either a tunnel or permission to set up BGP advertising for my subnet, and then it'll be time to figure out what to do with this project. I'm hoping to have a lot of fun with it and learn from you guys - see what you're doing, grab some great ideas, maybe leverage them with some of my own experience and knowledge. Thanks, Jim VE5EIS Regina, Saskatchewan, Canada DO70

Gateways to where?

by kb9mwr＠gmail.com

I have been reading this common thread on the.broadband hamnet forums. "Are there any lists with available tunnel connections?" On the portal, unless noted in the notes area, the only way to really tell is from looking up the geographic area for the listed subnet. This is probably something we should re-think. You shouldn't have to do all that leg work to see what areas have tunnels available. If we can make that easier to determine, I'd like to think more people will find what we are doing here on 44net more useful to them. Back to painful data loss recovery..

This really needs to be in the wiki, or else no one can find it. It can be dangerous for total newbs to read this, because it suggests the process is fraught with danger, which of course it's not. We all agree that it's actually completely trivial to put up an AP and connect to it from miles away. rmonline is also a good tool to quickly check links for LOS. There is also some Android app as well. http://www.ve2dbe.com/rmonline.html I don't do link calcs any more - there's just no need to. A pair of Nanobridges will work real well over a huge distance provided there is line-of-sight. Really, this stuff is point-and-shoot trivial now. A really important consideration with an 802.11 ham network, is keeping the snake-oil protocols separate from the ones that actually work! Viz, don't run mesh on an AirMax channel. AirMax can push a huge amount of data, even on a busy channel. Advice I'd give to a group of total newbies who want to build a network, is ignore all the tech talk and go buy a 2.4GHz AirMax sector access point, install on a nice high line-of-sight location, and just play with connecting to it from all around the place. There's nothing complicated about it at all. The tricky stuff does come later, but you'll get to that once you see the network up and alive, and your enthusiasm starts to take off. Newbs giving up early because it looks too hard is an avoidable tragedy. Steve ZL1BHD

Oh but that is because pe1chl.ampr.org allows only traffic from net-44. It is a NET system and I don't want to open it to the abusers and portscanners.

But maybe it is a characteristic of the way you traced, sometimes those extra encapsulations are not shown in a trace. I think the best solution today is to handle the net-44 routing in Linux and then when you want to run jnos put that behind an extra address that you route locally. Rob

It looks like you are not sending your pings back encapped to 169.228.66.251 You send them directly without encap. That may work if you have a bad ISP, but normally it should not work. You should have separate route tables for net-44 and public-IP traffic and send all traffic originating at net-44 back out via 169.228.66.251. I don't think jnos can do that. It really is outdated, you should consider migrating to Linux where this is no problem. (see earlier recipes provided on this list) Rob

Same symptom happens with several 44 systems, pings from Internet don't return. As pings don't return any other tcp function doesn't work either. Any help/guidance/sugestion will be much appreciated.

AMPR VPN

by lleachii＠aol.com

Ok, I finally took the time to setup my VPN. I made all the necessary CRT and KEY files, and was able to connect with OpenVPN for Android. I haven't had any success reaching any 44 hosts while connected, except the 44 devices local to the VPN server (I assume). Any ideas anyone? -KB3VWG

Avoid/delete own gw entry broadcast from amprgw

by Pedro Converso

Hello fellow crew aboard this 44 ship, I receive ok every 5 min update routes from amprgw in my jnos2 using rip2. Along with all gateways my own gateway is included affecting my local route that should be pointing to my default route, not to my gw internet IP. Question is: how I can avoid receive/load my own gateway entry ? or else how I can drop this entry coming from amprgw from my route table ? or how to make a permanent route that is not overlaid ? I tried with an at command: at 15 "route drop 44.153.0.0/23 encap+" but in less than 5 minutes the route is again overlaid with my gw entry from amprgw. Appreciate any suggestion/advice, Tks in advance lu7abf, Pedro Converso 73, lu7abf, Pedro

Re: [44net] AMPR VPN

by kb9mwr＠gmail.com

My OpenVPN server doesn't use keys compatible with LoTW like Hessu's. It's mostly just for myself and other local applications. However if you wanted I could email you a ovpn file and the keys off-list. In reality adding a OpenVPN server to your own gateway is a snap.

Re: [44net] AMPR VPN

My bad, I missed the part that you were using Hessu's VPN server. I have not tried that yet. Nor do I know how he has things configured. I do run a OpenVPN server on my IPIP gateway. And as I mentioned; the OpenVPN server hands out a 44 address in my subnet and routes all 44 client traffic back to the OpenVPN / IPIP server and it works great. 73' Steve, KB9MWR

Did you configure the OpenVPN server to push the route? push "route 44.0.0.0 255.0.0.0"

network summary software?

by kb9mwr＠gmail.com

I am looking for something like webalizer, but more encompassing. It has to run on a webserver. It should show a summary of various different types of network traffic. Things that come to mind that are close to what I am looking for: http://awstats.sourceforge.net/ http://oss.oetiker.ch/mrtg/ http://humdi.net/vnstat/ Something that analyzes the packets passing through and keeps statistics; ie. -most active IP addresses on the network in terms of traffic -stats on the types of traffic, www, ftp, etc/ Something that can provide insight into what applications and services are being used on the network. Does anything come to mind that fits this description?

Ubiquiti XR3-3.5 Cards (9cm 802.11a radios)

by Bryan Fields

I've bought a lot of these cards (over 200), and am making them available for 8.50 per card. They are tested for TX/RX being with in 3db of each other to a known good card on 3410 MHz, which you will not find on eBay :) These cover 3400 to 3700 mhz, and do 5, 10, 20 and 40 mhz channel sizes with +25dBm (600mW) output. These cover the top 100 mhz of the 9cm ham band in the US (3300-3500), and this is one of the few bands that is not shared with ISM users. Mikrotik sees them as 5ghz cards, and you just subtract 2ghz from the frequency to get the real operating frequency. Pictures of the innards: http://gallery.keekles.org/v/Radio_stuff/UBNT-XR3/ The UBNT website on them http://www.ubnt.com/xr3 Bart, AE7SJ, from the hamwan project has done some testing on them across the entire band and has the results up here https://www.hamwan.org/t/tiki-index.php?page=Ubiquiti+XR3&structure=HamWAN If you want some please email me offlist. I'll be bringing some with to Dayton and can meet people Thursday afternoon till Friday night to get them to you. If you want to do this I need your cell number and the number you want. 73's and lets get some high speed packet going on 9cm! -- Bryan Fields 727-409-1194 - Voice 727-214-2508 - Fax http://bryanfields.net

This is a frequently encountered problem, stemming either from lazyness or inexperience. Do we need a standard ruleset, and documentation to use it, and have this in the wiki? iptables or iproute2? Does anyone HAVE a working iproute2 setup? This stuff can be a pain I know - a bit like mowing your lawns, but if you don't do it, eventually you'll be sorry.

Hehehe, no I said "point taken and conceded", you read back and see! I AGREED with the man, AND conceded the point. Actually, I had allocated a 44/30 25 years ago, ran NOS over laggy 1200bd AFSK links on a 386 PC with one floppy, and my Internet connection was VT100 unix shell until I was allowed to run a SLIP link, so I am no newcomer, as you incorrectly state as fact. Egg on face again! Actually, hehehe there is also the situation where I have connected many many TCP/IP units in remote areas over wireless links, but the professional equipment I use is not really supported by the piecemeal approach so far with the 44net crowd - I hope to change that. What do you hope to achieve? Your sarcasm regarding the wiki is also noted. Why you might attack me about this is very surprising. Quite frankly, there was nothing of value in the wiki before I pointed out the glaringly obvious fact, and now that is changing fast, and it will keep changing until the path forward for all people is abundantly clear. I think you would just like to take the opportunity to be abusive. I address the issue concisely, learn from what is said, retract when incorrect, yet you evade all logic and pursue your ad hominem approach. I offer regret for offence taken, but you offer more offence? I don't think you are part of the solution, or part of any solution. For anything. 8-/

44/8 allocation

by lleachii.aol.com

John, Lol...you know I meant the major /8's that were handed out long ago that, to date, have never signed an agreement with their RIR. I stand corrected, though, there are Legacy allocations smaller than /8 that exist as well...but they are not listed in RFCs (as fixtures of the 'DARPA Internet'). -KB3VWG

Point taken and conceded. Best way to ask ISPs what they filter, is to simply ASK them. Why would you connect with some ISP and then spend months trying to debug something, when you could simply ASK them beforehand? Perhaps you like your head down such rabbitholes? I do not - I want to plug it in and it works.

If you really WERE working in a professional role on such equipment, and you ACTUALLY DID notice GRE packets missing, I would hazard a guess that you were perfectly capable of scripting up nc, nmap etc, with some bash or python to do as you ask, instead of trolling this networking group with your political goals. On topic though, I do recall some recent amendments to law (actually rules of a corporation, not real law) where it was specifically forbidden that any ISP rate-limit any service whatsoever, and then charge to un-limit it, so likely the govt is ahead of you on this one. Perhaps an email to the company concerned with a polite request for the same information, and an implied threat to write some network discovery tool might net you dividends you seek, or at least a straight answer - rare as they are.

Request for Software - IP Protocol Filtering Measurement

by Bart Kus

Hi, During some cell site work last night, I seem to have experienced Comcast dropping packets from point A to point B simply based on the fact that their IP protocol was GRE (IP protocol 47). I also found some posts on the Internet that claim Comcast wishes to charge more money to transport GRE packets. I'm not sure if this is true, or if I made a mistake somehow in my traffic handling. Therefore... Would someone be willing to create software instruments to measure this claim in general? I'd like to see a transmitter and a receiver piece of software that can run on Linux to generate and record a sweep of IP packets carrying all possible protocol numbers (0-255). The protocol payloads themselves don't need to be well-formatted, just the protocol number in the IP header needs to be set. Your software will be considered successful if it measures 100% of all protocols as available over an unfiltered (eg: LAN) link. The results of such a measurement would be useful in gauging the ISP quality of any given carrier. It seems we're moving closer to Selective Protocol Service Providers (SPSP) and away from true Internet Service Providers (ISP) if this GRE finding turns out to be right. --Bart

chargen service

by Brian Kantor

You should check to make sure that you have the 'chargen' service disabled on your hosts, and block it in your routers if you can. I've already contacted the people whose system was involved in this attack. - Brian ----- Forwarded message ----- Subject: Exploitable chargen service used for an attack: 44.x.x.x. It appears that a public "chargen" service on your network, running on IP address 44.x.x.x, participated in a large-scale attack against a customer of ours today, generating large UDP responses to spoofed probes that claimed to be from the attack target. chargen is an old testing service that generates large quantities of traffic with only a small request required. It is commonly enabled by default on old printers and other connected appliances, but it has no useful purpose over the open internet. Please block UDP port 19 (inbound and outbound) at your network edge, as this should stop these chargen attacks without blocking legitimate traffic. If the endpoint device that generated this traffic is configurable, please further investigate whether it is running a chargen service (and disable it, if so) -- commonly exploited devices include Cisco hardware that has "udp small servers" mistakenly enabled, old printers, old UNIX boxes with "chargen" running under inetd, and Windows boxes with the "Simple TCP/IP services" package installed. Also, it is worth checking if it is a machine that has been compromised, as some malware directly generates port 19 traffic, simulating chargen, and in this way masks its presence. If you are an ISP, please also look at your network configuration and make sure that you do not allow spoofed traffic (that pretends to be from external IP addresses) to leave the network. Hosts that allow spoofed traffic make possible this type of attack. ----- End forwarded message -----

help?

by Jerry

I have been having severe issues staying connected to the internet all day.. I did two things as a test.. I think its related to my Net 44 box. 1) Turned off the JNOS/URO box 2) Removed it from DMZ Going to see how things look. I think it is getting hit with junk from the internet .

How-To BGP?

by Jim Alles

Ok, so I am a licensed HAM, an amateur that has no formal education or job experience regarding networking. However, I believe I have a better handle on IT than most hams in general, present company excluded. (Anything I can do to help) I am assisting the Penn State Amateur Radio Club, a student organization, to get a couple of 1Gb network backbone connections lit up. One is dedicated to a D-star gateway (K3CR). The other location is the ham shack, for web browsing and other future uses, such as APRS Igate, IRLP or Asterisk. We will have a /29 assigned by the University. The two Microtik routers we have purchased are capable of BGP. The university will not advertise 44net, or allow me to announce BGP. sigh. Does anyone have any suggestions? Another regional resource we have in the state of Pennsylvania is PennREN. It is a partnership that built out fiber optics in a figure-eight footprint all around the state. They can provide connectivity (I would like to get a VPN server co-located in their facilities), but they also have dark fiber available. My long-term vision is to have a 501c(3) organized by hams light up a couple of those strands to create a regional 44net. Local hams/clubs would each have to provide their own 'last mile' I believe there is a group in Pittsburgh already doing something similar. I want to learn enough to understand the conversation. Thanks for the video! Jim Alles, KB3TBX

What is 44net?

by Cory (NQ1E)

Hello fellow radio/network geeks! While trying as much as I can to not come off as condescending, I would like to try and provide a little perspective so that we can hopefully clear up some confusion and speak in mutually agreeable terms. There seems to be many misconceptions by several people on this list who may be seeing 44net as a single service or network where everyone needs to be able to speak to each other and where all traffic sourced from it can be trusted. Oh, and RADIO :) The global internet isn't even one large network in that sense. It's actually just a concept that allows many different individual autonomous networks to coordinate and cooperate with each other while allowing them to share traffic among their users. Those in control of things like allocating IP space and DNS are only in that position because the majority of networks recognize their authority. Just like similar authorities on the internet, ARDC is just a registry that provides chunks of the globally unique IP space to individual networks which allows them to interoperate with each other or any other global network without conflict (but does not mean that they *must* work with other networks). In this case, they only agree to provide these services to networks that support amateur radio in one form or another. It just so happens that they also provide a service that coordinates IPIP tunnels so these networks can send encapsulated traffic to each other without needing to make their own peering arrangements with other networks on the internet at large. Since most people are only used to the idea of the internet being a "service" provided to them, it's easy to see why this can be confused. Those familiar with the HSMM projects may have noticed that they chose to operate in the non-unique 10/8 space in order to support autoconfiguration. However, once their project grew beyond those specific linksys models, they started having conflicts. Even now, those HSMM networks that are up and running can't communicate with users on other networks without complicated NAT tables. It would be much better to take advantage of our 44/8 resources for those projects by assigning blocks to each mesh island. That way they can start peering with other networks or other mesh islands directly. When asked why having 44/8 is important, this is a perfect example and there are many others. When talking about technical solutions to problems we come across, it's also important to consider that as hams, it's likely that our networks are experimental and will therefore have a wide range of configurations that could prohibit their ability to share traffic with some others. This should absolutely be encouraged as long as what they do does not impact any other network's ability to operate normally. Therefore, there is no "right" or "wrong" way to configure your network as long as you get your expected result. Just keep in mind that following best-practices is the best way to ensure compatibility. Ideally, those who operate the registry will shift closer to this way of thinking and start supporting more advanced users to do non-standard things (such as DNS or PTR delegation, for example). We also need to be careful about the terminology we use when referring to security, in order to avoid mistaken assumptions. Source addresses can be used in our case to provide a convenient filter against the majority of incoming junk internet traffic. However, this must not be confused for "authentication" or knowing *who* is sending you the packets. Make sure you understand the risks when opening up a service on your network. If you're trying to filter out most undesirables, source filtering can be okay. However, if you need to know who you are talking to, you must use another method. Also, myself and several others on this list may be in a good position to help if you need assistance in this area. Best regards, -Cory NQ1E Your friendly neighborhood radio hacker

Re: [44net] What is 44net?

What would this mean for the existing tunnel mesh? Today, with the existing full mesh of tunnels, there is no single point of failure between any gateway and any other.

Like I said some of these routers have 'unlimited' support for VPN/Tunnel clients. You can also tier this architecture. A single border router might be supporting 20 /16 VPNs/Tunnels to tier 2 routers, those routers might support 30 smaller subnets and so on --- There are some peering points that are relatively inexpensive (or free) and some individuals are in a position to be generous. This is no different than the FM repeater operator who pays for a site, equipment, and power costs to benefit a community of users, who may or may not make donations to that cost. Right now the total traffic on 44net could probably ride on a single home broadband connection. http://wiki.mikrotik.com/wiki/Manual:Interface/Gre The VPNs can be full up using available protocols MikroTik runs a variety of VPN protocols PPTP, L2TP, IPIP, ... Cisco has DMVPN -- you just have to find a common one between two routers.

Re: [44net] What is 44net?

Again, we are going into the weeds, and certainly beyond the intent of our licenses, and the regulating agencies. How do you know the identity of a ham on RF? When I make FM/SSB contact, I have NO means to authenticate the other parties - nor do they have a means to authenticate me. There is no rationale to apply authentication scrutiny to one mode of ham radio communications, yet, entirely ignore it on another.

How your script is written depends on these > things. What we see every time again when those issues are discussed is that there are people who approach AMPRnet not as a hobby amateur packet radio network, what it is, but as an extension of their network at work, usually they work in a professional datacenter or at an ISP. They want documentation and specifications because that is what they have at work. But this is a hobby, and there are not going to be specifications and documentation until someone who feels the need for them is going to write it. And they do not volunteer! The usual way to gather information has been to ask here, and possibly to dig in the archives of this list. That may be a frustrating endeavour for a professional network admin, but for the average hobbyist it is a learning experience and a way to get things working by gradually tweaking the configuration. Please note that once you got everything working, it is pretty much useless. So we should not take away the challenge of getting things working. When there is a clear recipe to get everything working, or worse yet: automatic configuration, what reason would there be left to start the experiment to begin with? A lot of AMPRnet is about learning, not about achieving the end result: a perfectly working network. Because the fun ends once that goal is reached. Another thing I want to note is that Bart and some of his peers like to use a lot of inside terminology they speak with their colleagues at work. They disregard the fact that the people on this list are radio amateurs, people with a technical interest but not experts in internet technology as he is. Every couple of months the same discussion springs alive and people start to pingpong technical terms between them and lose everyone else. And worst, they don't hesitate to slash the existing system, claiming all the time that it is legacy technology, that it is very unreliable, that it has to be replaced by the stuff they use at work because at work everything is so much better, etc. But remember: that is at work. And this is our hobby. We may have different objectives, like being able to comprehend things. It may well be that the optimal solution for an amateur packet network is not the one that is optimal for the large internet with the professional admins. We also use NBFM to talk to our friends, a technology that is considered "legacy" by the professionals as well. Some even use morse code. They are not going to abandon that because all the professionals have switched. > > It seems that to be allowed/compliant in AMPR, it just has to work > with the existing system. But what is the existing system? There are a > lot of existing systems and most of them are not documented. For > example, we learned via the mailing list that many AMPR gateways have > a static route to 44/8. This isn't documented in the encap file, it's > just added by their scripts. Where is the specification for this? I don't think many gateways have a static route for 44/8. I certainly don't have one myself. I could add such a route (as a null route), maybe that is a good idea. I'll think about it. What I do have is a default route in table 44 that points to amprgw. But the purpose of that is NOT to serve as a route for 44/8, its purpose is to route everything OUTSIDE 44/8 back out via amprgw. I require that because my ISP acts responsibly and has BCP38 in place. In the past, before I installed ampr-ripd, I manually ran a script that downloaded the encap file and installed the routes. I never put that in a cron job because the server for that file failed so often and I felt it was better to monitor the process and fall back to the previous encap file when things went wrong. As a result, my routes were often not completely uptodate and it was a good idea to route traffic for which I had no correct tunnel route back to amprgw. In those days that still worked, amprgw (mirrorshades in those days) would forward that traffic to the actual gateway. Nowadays amprgw does not perform that function anymore, so indeed it good be a good idea to add a 44/8 null route. But I don't think small issues like this warrant all the uproar, and I think it is much more fun to discuss pro's and con's of a certain configuration on the list than to throw stones at the existing system and demand everything to be overturned to look like an enterprise network.

Re: [44net] routable or private?

by Assi Friedman

There is no unified policy governing non-ham traffic on 44 networks. Each of us is bound to the terms and conditions of the respective national agency that issued our ham radio licenses. This is somewhat consistent with the mishmash of national regulations governing the global internet traffic. Also, most (if not all) amateur radio licenses weren't crafted with the internet in mind, and hence they don't provide clear cut guidance. Therefore, it is our responsibility as gateway operatorw to balance advancing the state of the art while maintaining compliance with our licenses.

Here I am sitting on my hands trying to figure out how to get my (already allocated MONTHS AGO) /24 connected to the flamin internet. No one seems focussed on making a wiki entry about THAT. Rather, they'd be happier tunneling their little private network to someone elses'. It seems that many other groups have been waiting YEARS for this assistance or documentation, and MANY other groups who have just given up in disgust. Would the people who ACTUALLY HAVE a properly connected (live to the internet) 44 subnet that they openly brag about, kindly document the bloody thing in the wiki so I can do it as well? This isn't a dick measuring group, its a networking group. You know what you're doing, so write it up so mere mortals can achieve a positive result as well. There needs to be a sample equipment list with DIY workarounds for those with time but not money, and there needs to be a VERY well written document-set to hand to my ISP so I don't scare them into just plain refusing my request, or unduly taxing their tech team.

Perhaps a overview of internet routing process is needed, as I want the 44/net to be a place to learn, but we need to ensure people understand what they are doing before messing with the global table. This is quite simple, but the LoA (letter of authority) and required information can be daunting to those who've never done it before. Also, if you're on the digest version, can you change the subject of your reply? I've been ignoring this thread since I didn't feel like reading it all at once. 73's -- Bryan Fields 727-409-1194 - Voice 727-214-2508 - Fax http://bryanfields.net
