Device permissions 1

[verland]

I have a machine with a few ttyS's on it and can only run minicom as root ("cannot open /dev/ttyS3ermission denied&quot. I chowned them to me and it works fine.

Is that a normal thing to do? any better ideas? Thanks!

Usually not a good idea.
Easier would be to assign a viable group permission
chmod 770 /dev/tty3
chgrp wheel /dev/tty3
Then add your users to the wheel group.
But still not a good idea.

Some common ways to do this is to make minicom suid, or
to create some sudoer users for minicom and sudo
minicom.

That's what I thought, I'd chowned it back to root anyway after finding out you need to run root in minicom just to switch tty ports. Thanks!
