[nos-bbs] *****SPAM***** NETROM REACHABILITY, INP2011 (INP3), and NRR

[n0mr at lakenet.com]

Maiko,

In the past we had problems with JNOS to BPQ AXUDP netrom disconnecting sometimes from a few minutes to days. It seemed JNOS would initiate a disconnect request maybe based on an inactivity timer but there is no parameter I'm aware of. BPQ would initiate a reconnect but sometimes would take days.

When BPQ switched to using INP3, there seemed to be a lot more traffic between nodes and I don't see JNOS initiating a disconnect. This workaround is doing well for us. XRouter AXIP using INP3 also stays connected. JNOS to JNOS AXIP is always connected.

nope, it became very time consuming, then I kinda forgot about it.

This was a project I wanted to do that would actively got out and
make sure nodes in the netrom table were 'reachable', and if not
they would be removed, kinda like a garbage collection of sorts.

this is INP3, yes, still read only, but many have reported stability issues
with it, and it too became very time consuming back then, the documentation
was horrible with regard to the protocol, and I wrote it based on some
linux code
from before that time. I've always meant to go back to it, but ... you
know ...

It was quite technical, overwhelming to work on, I don't think it was ever a
good implementation (read only just allowed JNOS to mingle with Xnet and
other networks, it never wrote any INP3 back to the system, thank god).

Feedback from people would be nice. I have received some from a few of
the veterans on here, but just never got to it .. usual excuses ...

Works for some systems (Xnet and JNOS that have it compiled in), examples :

[JNOS-2.0m.5F-B1FHIM$]
You have 101 messages  -  81 new.

If I telnet to Jack's system and I do the same to my NETROM call (that's
important) :

   Telnet session 1 connected to aa6hf

   JNOS (aa6hf.ampr.org)
