[nos-bbs] Two Tunnels in JNOS?

[Chris Maness]

I used to run TNOS with two serial links to Linux.  One with the real
internet address, and the other to provide 44-net connectivity for the
Linux host it was running on.  Is this possible with JNOS tunnel
devices?  I have tried on two different systems, and failed on both.

Here is the autoexec I am working on:


#
# A minimal autoexec.nos for a JNOS system having network connectivity to
# the linux box on which it is running on. From JNOS you can telnet to the
# linux box, and from the linux box you can telnet to JNOS. Any packet radio
# users can connect to JNOS through the single RF port which can be any TNC
# running in KISS mode. This configuration also allows JNOS users to exchange
# mail with other JNOS users (local mail), using the Send and Receive cmds.
#
# The jnosinstaller was designed for first time JNOS users, giving them
# something to start playing with.
#
# This autoexec.nos was GENERATED by jnosinstaller (version 2.1), which was
# released in January of 2008. The original version was written in July of
# the year 2005 - both versions written by Maiko Langelaar / VE4KLM.

# by shelling out to the linux command line and running 'ifconfig' command.

Anything obviously wrong here?
