Re: [44net] On the Issue of Subnets (fwd)
by Tim Osburn 25 Feb '12

This might be a good time to implement a rwhoisd server for the whole 44/8 network. This way for the people who want to register a block of any size we can have an easily accessible and viewable whois entries. Also anyone, anywhere can find out what is assigned to who regardless of it's block size and regardless if there are DNS entries or not. Then it would fall back to the regional coordinator if no entries were made for the query being checked, and then back to the top parent of Brian for 44/8 of no coordinator assigned. This is a proven method as ARIN has been using this for years on their whois server. Works very well. Assuming that if 44.X.X.0 is assigned something in DNS that it's broken into a /24 I believe is not a good idea as it might actually be a smaller or larger subnetmask. /24 can be very wasteful if you're not using most of it. I would say it would be more common to hand out /27's or /26's. This would also lend it's self nicely into IPv6, since that is supported as well if we get space.

mailing list protocol change
by Brian Kantor 24 Feb '12

24 Feb '12

I've set the 'reply to list' option ON for this list, so by default your replies to discussions should from now on be automatically directed to the list rather than to the original poster. You'll probably have to take specific action in your mail client if you want to reply privately only to the person posting the message. I think this is more in keeping with the spirit of the list, and it had been asked for by a few of the subscribers. If this causes difficulties, please let me know and I can turn it back OFF. - Brian

Sorry: I crossed my outgoing with Brian and Davids incoming. You're already on it Bill -------------------------- Well, for starters, it looks like the address you posted here is: 44.9.0.1, and you state belongs to WA6NMF. However, I show no such address on the network. I do show an address for WA6NMF, but it is 44.4.9.1 not 44.9.0.1. wa6nmf IN A 44.4.9.1 wa6nmf-1 IN A 44.4.9.2 wa6nmf-2 IN A 44.4.9.3 wa6nmf-3 IN A 44.4.9.4 Now, I also show the 44.9.x.x as a discontinued range.

Gateway ip/netmask pair

Is it just me or we have a error in the gateway routing table? entry: 44.9.0.1/255.255.255.252 via 207.111.203.194 This gives a invalid subnet/netmak pair and gets ignored by rip44d. Should be either 44.9.0.1/255.255.255.255 or 44.9.0.0/255.255.255.252 73 de Marius, YO2LOJ

[Length: 64] It appears to be an IPIP packet from the gateway, which then contains another IPIP packet sent by 76.114.219.34 to the gateway, which again has another IPIP packet that my trace tool no longer shows. I don't understand why the gateway delivers these packets to me. As it looks like 76.114.219.34 is indeed a valid gateway in the system, I assume a misconfiguration rather than malice for now. But probably it would be better when amprgw just rejected all IPIP traffic that includes another layer of IPIP within it. Rob

Linux tunnel gateway configuration?
by Brian Kantor 22 Feb '12

22 Feb '12

Does anyone have a step-by-step set of instructions for configuring a Linux host as a tunnel subnet gateway for AMPRNet? I'd like to have a proven list of all the commands that have to be entered to set one up. I think it would be very helpful and I don't have such a document in my archives. Thank you! - Brian (PS: this is the first message through the new mailing list setup; if you encounter any difficulties please let me know.)

Here is the snippett from the /NOS/AUTOEXEC.NOS where it sets up the TUN0 interface. Below that, I show the output of IFCONFIG and ROUTE on the Linux box, for your reference. In this example, 192.168.0.5 is the address of the Linux ethernet card and 192.168.0.44 is the address of the JNOS application running on Linux.

I do *not* recomend forwarding SMTP unless you have a solid way to prevent spam from the public Internet getting out onto your RF network. If your JNOS application is running the ENCAP.TXT route table and uses the 'encap' interface, DO NOT PORT FORWARD ANYTHING! Instead, define the 192.168.0.44 ip address of the JNOS application as your "DMZ Host" so that ALL protocols (TCP, IPIP Protocol-4, and others) will be automatically routed to the JNOS application where JNOS'es 'ip access' and 'tcp access' firewall rules will decide what gets through for processing/routing.

my KA9Q NOS tunnel driver for OpenBSD on i386 and macppc is available
by Isao SEKI - JM1WBB 22 Feb '12

22 Feb '12

Hello gateway operators, A few days ago, I fixed a bug of my KA9Q NOS tunnel driver for OpenBSD for Little Endian CPU and my gateway, 44.129.192.1 returned into ampr.org. That is very light weight and running kernel land. My package is available at "Nostun Project" in my home page, http://gongon.com/JM1WBB/ but I'm sorry documents and patch file are very old... 73, Isao / JM1WBB
