I have a Portserver8 running with realport software under F10. But the ports are in group root. I would like to change the group to uucp to match the regular ports and allow users in uucp group to access. I can do this with
chgrp uucp /dev/ttyaa00
and similar for other ports. But want this done automatically at startup for run levels 3 and 5 (at least). I tried adding the chgrp commands to the end of /etc/rc.d/rc.local because this is said to be the last startup script to run. But the log says
chgrp: cannot access ‘/dev/ttyaa00’: no such file or directory
How can I do this?
