    Earlier, listen was by default installed with the SUID bit set and so any
    user could run it with root privileges. As this is considered somewhat
    dangerous (a bug in listen could allow a local root compromise), ax25-apps
    was changed not to do this. So now it is up to each sysop to enable it if
    needed. You can do this as root:

     chown root /usr/bin/listen # if not already...
     chmod u+s /usr/bin/listen
