I haven't kept track of which versions do exactly what, but I did see permissions on ttyS0 keep reverting on some recent versions of RH or Fedora. Three changes I've had to make were: /etc/inittab: -------------------------- # NO logins on ttyS0! ### co:12345:respawn:/sbin/agetty ttyS0 9600 vt100-nav /etc/security/console.perms: -------------------------- # Added <serial>=/dev/ttyS[01] ... # Added <console> 0660 <serial> 0660 root.uucp /etc/securetty: -------------------------- # DA removed: ttyS0 -- Donald Arseneau asnd@xxxxxxxxx -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
