[nos-bbs] Suse 9.1, jnos 2.0e

Ok all,
I'm having more problems with my Suse 9.1 jnos implementation. I'm pretty sure
my stack overflow problem is a problem with my tnc. I'm waiting to get
another tnc andradio combination that I can get to work to see if I can
confirm this.
I began to test being able to telnet into the jnos system from outside and
find some troubling indications.
I cannot ping across the tun0 interface in either direction, it looks like I
get no reponse. I cannot telnet across the tun0 interface in either
direction, I get no response. Yet all the routing and everything looks just
like it does on my other Suse 8.2 system that is working. The screwy thing is
that when I ping into the system, ifconfig shows the RX and TX packet and
byte counts incrementing but nothing seems to happen.
my systems look like this
timsatern (192.168.10.39) <==> saternjnos (192.168.10.38)
bagend (192.168.10.12) <==> jnos (192.168.10.33)
Here are some dumps from the various systems. I honestly can't see anyting
wrong and I'm stumped. Is this a jnos thing or a Suse thing? If you look
carefully at the the jnos 'tcp status' dumps on the Suse 9.1 system, the
tcpRetransSegs and tcpOutRsts values would seem to indicate a problem but I
just don't know enough to evaluate what that might be!
Any suggestions anyone?
