sol2.6 - ttymon not allowing console logins

Post by Justin M. Strein » Fri, 12 Dec 1997 04:00:00

I have a pair of Solaris 2.6 boxen here which have stopped accepting console
logins.  Login attempts produce the following error:

machine1 console login: root
Warning -- ttymon cannot allocate controlling tty on "/dev/console",
        there may be another session active on this port.
Login incorrect

have owner/group root/tty, mode 620.  I didn't see anything out of the ordinary
in /etc/logindevperm or /etc/ttydefs.  /usr/lib/saf/ttymon is owned by
root/sys, mode 555.  The ttymon process itself is running.

Console access is through a small terminal server which acts as a serial
console manager.

Any other ideas where I should look?


1. NIS allows remote login but not console login?

I setup a Solaris 2.5 machine as an NIS client (HPUX 10.10 machines are
the NIS servers), but the Solaris machine is only allowing logins
through NIS _remotely_! That is, if a login is not found in the passwd
file but can be found over NIS (using the "+" in /etc/passwd), that user
can only rlogin/telnet to the Solaris machine, but not login at the

Okay, to be even more specific (I did a little troubleshooting), login
to Solaris (the windowing system) or CDE does _not_ work. However, a
text-only console login works fine (just like rlogin/telnet).

Any ideas why text-only logins work but not windowes console logins? I
don't want to resort to a script that copies necessary logins to the
/etc/passwd file.


PS: I'd appreciate email replies as well, since I don't get around to
this group often (but I did read the FAQ and as many posts about NIS
before posting this!)
