Perhaps this is a known problem, but I only found one instance of someone
describing it on the net with no follow-up. I just installed openssh
(3.6p1) on a linux system (running an old 2.0.34 kernel) with privilege
separation disabled and get the following messages in /var/log/messages:
Apr 2 15:48:34 ernestine sshd[6153]: error: ioctl(TIOCSCTTY): Operation not
permitted
Apr 2 15:48:34 ernestine sshd[6153]: error: open /dev/tty failed - could not
set controlling tty: Device not configured
The effect is that ^Z's are mostly ignored (but not by vi) and ^C kills
the session, rather than a running program.
After poking around the net and the code a bit, I found that changing line
318 in sshpty.c from:
if (ioctl(*ttyfd, TIOCSCTTY, NULL) < 0)
to
if (ioctl(*ttyfd, TIOCSCTTY, 1) < 0)
seems to fix things. Is this a known bug or something peculiar to my
installation? Let me know if there is any further information I can
provide. Thanks for any input.
