NAME

       axspawn - Allow automatic login to a Linux system.

SYNOPSIS

       axspawn [--wait, -w]

DESCRIPTION

       Axspawn  will  check  if  the  peer is an AX.25 connect, the callsign a
       valid Amateur Radio callsign, strip the  SSID,  check  if  UID/GID  are
       valid, allow a password-less login if the password-entry in /etc/passwd
       is “+” or empty; in every other case login will prompt for a  password.

       Axspawn  can  create  user  accounts automatically. You may specify the
       user shell, first and maximum user id, group ID in the config file  and
       (unlike  WAMPES)  create  a file “/etc/ax25/ax25.profile” which will be
       copied to ~/.profile.

SECURITY

       Auto accounting is a security problem  by  definition.  Unlike  WAMPES,
       which  creates  an  empty  password field, Axspawn adds an “impossible”
       (’+’) password to /etc/passwd. Login gets called with the “-f”  option,
       thus  new  users  have the chance to login without a password. (I guess
       this won’t work with the shadow password system).

       Of course axspawn does callsign checking: Only letters and numbers  are
       allowed, the callsign must be longer than 4 characters and shorter than
       6 characters (without SSID). There must be at least one digit, and max.
       two  digits within the call. The SSID must be within the range of 0 and
       15. Please drop me a note if you know a valid  Amateur  Radio  callsign
       that  does  not  fit this pattern _and_ can be represented correctly in
       AX.25.

OPTIONS

       -w, --wait
            Disables the prompting for a password if  the  password  entry  in
            /etc/passwd is either a “+” or blank.

FILES

       /etc/passwd
       /etc/ax25/ax25.profile
       /etc/ax25/axspawn.conf
