Description hjl 2002-04-06 01:12:14 UTC

If you put a symlink from /dev in /etc/securetty, like

# cd /dev
# ln -s ttyS0 ttyFOO
# grep -v ttyS0 /etc/securetty > /tmp/securetty
# echo ttyFOO >> /tmp/securetty
# mv /tmp/securetty /etc

root can't log in on /dev/ttyS0 even though
ttyFOO is in /etc/securetty

This can be viewed as a feature - you are not logging in from ttyF00
but from ttyS0, so ttyS0 should be in securetty not ttyF00.
