Description bwess 1999-09-28 08:51:32 UTC

This seems related to bug #3909.

I updated several machines from RH5.2 to 6.0 and built a
2.2.12 kernel. Now all of them show this error whenever a
tcsh is opened by a user (at all logins and even when e.g.
less calls lesspipe.sh to find out how to handle a file).
Stracing around I saw that /dev/port isn't even accessed by
the called program itself, the device seems to be accessed
somewhere else.
If the permissions are wrong (666, see 'man 4 port') the
'Permission denied' changes into a 'Operation not
permitted'...

Please mail me if you can't reproduce this bug.

TIA

You might want to check for a use of kbdrate from util-linux. There are
some fixes in util-linux for accessing /dev/port (and PAM console is involved).

Changing component to util-linux. Please change back to tcsh if that's where the
fix needs to be.

closed, lack of input.
