That's a bit strange. Is the ax25 Listen command SUID? I know it
(Listen) works once the associated serial port is set RW for the
regular user. Maybe Listen is doing some magic with the serial port
that a regular user program wouldn't try.
Yes. This is a Linux kernel driver limitation, so we can't work
around it. Xastir has code in it to drop to regular user privileges
when it doesn't need the SUID root privileges though, so you're
_relatively_ safe doing this:
su
chmod 4755 /usr/local/bin/xastir
Thanks. I'll try that right away this evening.
Adding a pop-up warning dialog for the ax25 setup should be a good
beginner exercise in tweak the X-winders software.
