[nos-bbs] "Munge" script for ENCAP.TXT

[Bob Nielsen]

The "munge" script can be found in the Linux AX25-HOWTO
<http://www.tldp.org/HOWTO/AX25-HOWTO/index.html>.  This document  
covers using this script with a Linux Node setup rather than with  
*NOS, so you will have to route things from JNOS to the Linux first  
(the JNOS documentation should be helpful in understanding what is  
needed).  I have seen installations doing what you described, but  
have never run across any detailed documentation (it would be a great  
addition to the JNOS docs).

If the user has separate (AMPR and non-AMPR) IP addresses for the  
Linux side, encap can be handled in the same manner as with MS-DOS as  
is described in the JNOS docs.  In my experience (several years ago),  
running JNOS in this way under Linux was faster and more stable than  
under DOS on the same hardware (64 MHz i486).
