The axspawn program is a simple program that allows AX.25 stations
who connect to be logged in to your machine. It may be invoked from the
ax25d program as described above in a manner similar to the node
program. To allow a user to log in to your
machine you should add a line similar to the following into your
If the line ends in the
default * * * * * 1 root /usr/sbin/axspawn axspawn %u
+character then the connecting user must hit return before they will be allowed to login. The default is to not wait. Any individual host configurations that follow this line will have the axspawn program run when they connect. When axspawn is run it first checks that the command line argument it is supplied is a legal callsign, strips the SSID, then it checks that

+then the user is logged in, if there is anything in the password field the user is prompted to enter a password. If there is not an existing account in the
/etc/passwdfile then axspawn may be configured to automatically create one.
You can alter the behaviour of axspawn in various ways by use of
/etc/ax25/axspawn.conf file. This file is formatted as
# /etc/ax25/axspawn.conf # # allow automatic creation of user accounts create yes # # guest user if above is 'no' or everything else fails. Disable with "no" guest no # # group id or name for autoaccount group ax25 # # first user id to use first_uid 2001 # # maximum user id max_uid 3000 # # where to add the home directory for the new users home /home/ax25 # # user shell shell /bin/bash # # bind user id to callsign for outgoing connects. associate yes
