New subject: Network map of active AMPR stations -- Packet "proxy arp" in Linux and/or JNOS?

23 May 2012


      Hello AMPR folk,
I'm curious if there is an map of *active* geo-ip located AMPR stations 
out there?  Ideally, I'm thinking of something like the various CONVERSE 
maps out there .. for example: http://www.wwconvers.ampr.org/ . The 
Michagan AMPR people do have a live monitoring system but it's text 
based:  http://server1.nuge.com/~drg/network.html and I'm specifically 
looking for a Northern California map.  Maybe there is something like an 
MRTG system that actively probes these systems from say the AMPR hub in 
San Diego?
I'm also curious if anyone has ever heard of the following:
I'm going on a vacation this summer where I know there isn't any 
reachable packet systems (both APRS or known packet systems) due to the 
mountain terrain.  I know because I was there last year and though I 
could hear very faint packet stations, nothing could be decoded.  What 
*is* available here is the commercial cell network and what I was 
thinking was tethering my Linux machine to the cell IP network and 
running an AXIP/AXUDP tunnel to re-link into the fairly extensive 
145.050 KB2KB packet network:  http://varmintal.com/ahamp.htm .  I don't 
think this would be too difficult but what I'm trying to figure out is 
if it's possible to have my Linux machine send beacons, netrom updates, 
etc. from my machine via a tunnel to a remote AMPR station (proxy arp if 
you will) and then have all those AX.25 packets broadcasted on RF from 
there.  There are a few Northern Califnornia Linux-based stations I know 
of that are on AMPR with JNOS that might be willing to try something 
like this but I wanted to run it by the group to see if it's been done / 
impossible / etc.
