OpenWRT AMPRNet config
by Roger 07 Jan '19

07 Jan '19

Hi, I’m following the instructions at the below link to use OpenWRT as a 44Net gateway. I’m confused about some of the instructions. What should <AMPRGW> be replace with in the route. This has me confused as well: “an interface instance for a new VLAN and bridge (the example above uses AMPRNET), add it to its own firewall zone using Input: Accept (if you wish for you AMPRLAN devices to reach the router), Output: Accept and Forward: Drop (or Reject). Assign an IP from your allocation to this interface, you will configure this IP on your devices as the Default Route/Gateway address.” I created the AMPRNET interface but i put the 44Net allocation ip in the gateway of that interface, reboot after doing everything else, I get an error from Ampr-ripd that the interface doesn’t exist. If anyone has done this on a OpenWRT router, would you be willing to share your firewall and network config files so that I can learn what I’m doing wrong. http://wiki.ampr.org/wiki/Setting_up_a_gateway_on_OpenWRT Thanks Roger VA7LBB

Re: [44net] Bring your own IP at Amazon Cloud ?

> AWS instances have private IPs that are mapped (elsewhere) to a public IP, at no point does the public IP/Network exist on the AWS instance. That was true for legacy EC2. Now days, instances are launched in VPCs where you can choose to use your own public or private IPs directly on the network interfaces. You can also now have multiple interfaces on an instance.

Bring your own IP at Amazon Cloud ?
by Toussaint OTTAVI 07 Jan '19

07 Jan '19

Hi all, We are already announcing a subnet with BGP via a low-cost virtual instance at Vultr. It works fine. As we'll soon deploy our second data center, and we'll start migrating from our old-style 10.44.0.0/16 private addressing to full AMPRNet addressing, I was wondering if I could find a second low-cost BGP provider for redundancy. I saw that Amazon now provides "Bring your Own IP" features : https://aws.amazon.com/fr/blogs/networking-and-content-delivery/introducing… Did someone already tried it ? Would it be suitable for AMPRNet announcement ? Is this feature available outside of the U.S ? Amazon seems to provide free account during one year. Are there any volunteers to try out ? 73 QRO & Happy New Year de TK1BI

Setting up a tunnel on a Cisco 2921/k9 Router
by David Pechon 04 Jan '19

04 Jan '19

I am trying to setup a Cisco 2921/K9 router. The router has 3 gigabit ethernet ports and a CISCO EHWIC-4ESG 4-Port Gigabit WAN Interface Card<https://www.ebay.com/itm/CISCO-EHWIC-4ESG-4-Port-Gigabit-WAN-Interface-Card…>. I can not get a static IP address from Spectrum so I need to set up a tunnel. Does anyone has have any dealing with this type of setup. I am looking for a way to where to start from. 73's David A.

Scanning traffic; How much does the gateway get?
by Jeremy Cooper 03 Dec '18

03 Dec '18

Since taking on a BGP routed /24 several weeks ago I've occasionally watched my gateway firewall logs in realtime to get a sense of how much traffic I get from the Internet at large for my little section of the AMPRNet. I get an average of 2.7 packets a second in random scanning traffic. Scaling this up to the /8 that comprises AMPRNet, I surmise that the UCSD gateway must get something like 176k packets a second. Assuming an average SYN packet of 20 bytes, this is something like 283 gigabytes per day. Is that about right, Brian? -J

Re: [44net] Why if you are yahoo.com or gmail.com mail user, you probably won't see this message :-)

> The subject line of this message is clearly wrong. > 255 of the 821 subscribers to this mailing list use @gmail.com > mailboxes. > If there were a problem with gmail, it would have shown up long > ago. I have a bit mixed feelings about it. As a coordinator I get regular mail from gmail users and often experience that my replies do not arrive or get marked as SPAM. I get reminders about requests that I have already processed, and sometimes a message "oh sorry I found your reply in the SPAM folder". At first I blamed my use of an @amsat.org address, and also using that address as a From: address in my replies. Due to the SPF record on amsat.org it can be expected that such use leads to marking of mail as suspicious. So I switched to using another alias service (@vrza.nl being offered by one of our amateur radio societies), but the situation did not improve. I still get reports of my mail ending up in the SPAM folder at gmail. But the vrza.nl domain has no SPF record. Apparently there is some relation to the user receiving the mail. Some users receive all my mail without problem, no matter if sent from @amsat.org @vrza.nl or another source. Others report that it is treated as SPAM for each of those. Not being a gmail.com user myself, I do not exactly know what features it offers for whitelisting or other special treatment of mail, or maybe what it learns automatically. It could be that sending back and forth several mails eventually leads to an address getting on the whitelist automatically. The same could be true for mail server IP addresses (like a mailinglist server), and it could be that knowledge built in the past also affects the results of new SPAM criteria added later. It is all a bit opaque, and when you want reliable and predictable mail service, using those mailservices certainly is not the best choice... or at the least check the SPAM folder regularly. (but I have also received reports of mail being dropped and not placed there) Rob

Why if you are yahoo.com or gmail.com mail user, you probably won't see this message :-)
by Neil Johnson 12 Nov '18

TL;DR: In never ending battle against SPAM and phishing attacks, some email providers are now using DMARC, rejecting or marking as SPAM email if the originating mail server doesn't match the authorized ones for the provider's service. For example: - Yahoo! is flat out rejecting e-mail from yahoo! mail users if it comes from non-authorized servers. - Google is marking e-mail from gmail users as SPAM if it comes from non-authorized servers. Unfortunately this breaks mailing list software like mailman (used for this list) which tries to make e-mail from the list appear as if it is coming from the original sender. The changes that are required to fix the issue change the functionality of the list software in ways users may not like. I found this out while applying DMARC for my my own domains. More info can be found at these sites: https://wiki.list.org/DEV/DMARC https://dmarc.org/ Fun. -Neil -- Neil Johnson
