permissions on files in /dev/pts

[Quark]

Hi,

all the files in the /dev/pts directory on my system have crw-rw-rw permissions.
For security reasons I am advised to remove the world-write perm on those.
Given the fact that they are device files, can I remove the 'w' flag for 'others' without danger?

The real point is what are the perms on /dev/pty? It should not have write perms to others.

/dev/pty does not have write permissions for others, but the files in /dev/pty do

Kris,
not a definitive answer, but changing the persmission on the files in /dev/pts did not SEEM to impact my sessions.

That is OK. the perms on files under /dev/pty can be write to all. It is not a problem.
