Description Chris Evans 1999-10-19 21:23:23 UTC
I have a full RH6.1 install.
As a user I run "screen".
I notice I get allocated "/dev/ttya0", and the permissions
are -rw-rw-rw-, owned by root. This is very dangerous! It
looks like screen has failed to use /dev/pts/0 (UNIX98 pty
xterm and rxvt handle pty's correctly, screen should mimic
their behaviour.

PS. I like screen's usage of user-private .screen
directories, much better.

Comment 1 Bill Nottingham 1999-10-21 19:57:59 UTC
Fixed in screen-3.9.4-3, in the errata.

(As an aside, using the user private .screen directories, while
more secure, breaks on Linux<->non-Linux NFS. :( )
