I find these messages in my logfiles. What has changed recently? The access to the tty devices is crw-rw---- and owned by root.tty. Distribution is Debian GNU/Linux unstable. sshd[4196]: (pam_securetty) access denied: tty 'ssh' is not secure ! xscreensaver: (pam_securetty) access denied: tty ':0.0' is not secure ! Please cc: me since I'm not subscribed to the list.
