I've been having a major problem with logging in as a non-root user from agetty. It turns out that removing pam_console from the specifications in /etc/pam.d/login fixes the problem. Reproducible: Always Steps to Reproduce: 1. Bootstrap from stage 1 (probably not necessary at all) 2. Ensure pam_console is specified in /etc/pam.d/login 3. Attempt to log in as a non-root user. Actual Results: Password checking appears to work as it should, and a syslog message is entered saying that a "session" has been opened by PAM. After a brief delay, the system drops back to agetty. Expected Results: Logged in the user.

I've been havein similar problems with [xg]dm but login works fine though. When a user login using [xg]dm and pam_console is enabled in their pam configs /dev/null is altered. The following seems to be happening login: chown user /dev/null chmod 660 /dev/null logout: chgrp floppy /dev/null This seems very strange to me =P I have tried to hunt this down with strace, but I can't find the right process to strace. Any tip on how to proceed? I have: sys-libs/pam-0.77-r1 sys-fs/udev-025-r1 sys-kernel/gentoo-dev-sources-2.6.5-r1
I solved the problem, mine at least. I had put a line in /etc/fstab calling /dev/fd/0 the device to mount at /mnt/floppy... /dev/fd0 should it be! Strange errors from such a small spelling error. =)
Default is now pam_console disabled. PS, pam_console do not touch /dev/null by default due to console.perms file, so it might be something else.
Well /dev/fd/0 beeing the special file it is and all actually made pam_console change /dev/null. just don't do it =)
