What is the AMPRGW machine based on?

There's no QoS policy in effect, but 'amprgw' is getting hammered at the moment, with inbound packet drops peaking in the 25% range so performance is going to be horrible. It's hard to see precisely what's happening but it looks like multiple hosts (possibly a botnet) are sweeping through the 44/8 range looking for something. There's not much we can do about this in the short term. Long term includes a higher-performance machine with faster network interfaces. - Brian _________________________________________ 44Net mailing list 44Net(a)hamradio.ucsd.edu http://hamradio.ucsd.edu/mailman/listinfo/44net

Sounds like an excellent research topic for a UCSD summer intern.

Some hosts from net, rest masq'd?

I am doing that on my system as well, but rather than using a separate rule that is matched by the mark, I use the mark to enable the masquerade in POSTROUTING. (using a -m mark --mark 1 match) But of course it can be done either way. Rob

Some hosts from net, rest masq'd?
by Steve L 19 Jul '15

19 Jul '15

I had a guy ask me who I don't think is on this list yet, if its possible so have some 44 ips behind his gateway reachable from the public net, and all the remaining to use masquerading rather than the default 44/8 UCSD route. I told him I am sure it can be done. I am sure there is more than one way to do this. Here is what I came up with, I mark the traffic type by matching source address (I am using some hosts on my lan to test). Set a rule for that, and then finally set a route based on that rule. Here is what I have: http://www.qsl.net/kb9mwr/wapr/tcpip/startampr-n3fe I am not sure I am doing it right as the iptables marking and ip rules are a little greek to me. I am looking for input, suggestions etc. There may even be a much easier way that I haven't thought of. It seems to work, but I have said that before and turns out I was logged into something other than what I thought for testing. Seems a bit sluggish from the net though, but maybe there is just congestion right now. Thanks Steve, KB9MWR

Issues setting up tunnel gateway
by Chris S. Munz-Michielin 15 Jul '15

15 Jul '15

Hi everyone, I'm just starting to setup an AMPRNET node and am running into some difficulty setting up a Linux gateway using the rip44d daemon and was hoping someone has some pointers. I've been following this guide: http://wiki.ampr.org/index.php/Ubuntu_Linux_Gateway_Example and start running into trouble once I try and get the rp daemon running. I've managed to download and extract the latest tar file from: http://www.yo2loj.ro/hamprojects/ampr-ripd-1.13.tgz and it seems to compile and install fine. The next step, according to the guide, is to run ./find_pass.sh but when I do that I get the error: Tunnel socket: Setting SO_BINDTODEVICE: No such device I took a look at the contents of the find_pass.sh file and it seems to contain the command ./ampr-ripd -d -i ampr0 so I decided to run ./ampr-ripd -d -i eth0 from the command line and I get the message: Waiting for RIPv2 broadcasts... but it never prints out the "secret" password. I am running Debian Jessie as my OS and have registered a gateway on the ampr portal. Just wondering if there's something obvious I'm missing here? Cheers, Chris VE7ALB in Victoria BC||||

What's a goot 44.x test peer
by Assi Friedman 15 Jul '15

15 Jul '15

Folks: I am trying to bring my 44 host back online but am having some issues (not receiving IPIP traffic from mirrorshades.) What's a good 44 peer I can test traffic from Internet->44.x to and 44.x -> 44.x. Not planning on flooding, mostly pinging. Thanks, Assi (kk7kx.ampr.org)

I would be interested in testing this as an endpoint. Let me know what you need from me, on or off the list! Thanks!!

BPQ and 44 IP's
by William Lewis 14 Jul '15

14 Jul '15

I'm hearing that the latest BPQ software can do 44.x.x.x IP Addressing? Can anyone confirm this? If so, I have a friend in Nevada that wants to set up his BPQ station to link with me using our 44.x.x.x numbers.
