Yep.  Exactly what I was thinking.

Another thing to check is that you've done the following against the Xastir executable to allow it to run as root when opening the AX.25 port:

     sudo chmod 4755 /usr/local/bin/xastir

or wherever your Xastir executable lives...  The above is the default if you compile from sources without any special flags to relocate it.

A networking port has to be opened as root.  The above command sets the SUID flag on the executable, allowing it to run as root when the executable requests it.  In the Xastir code we assume root privilege only during the opening/closing of ports, and drop back to normal user privileges otherwise.  Good security practice.
