Description Eric Bourque 1999-12-03 19:37:15 UTC
After rebooting a RH6.1 system which has been working fine for several
months, I suddenly can not log in as any user but root. There is no
/etc/nologin file, I have updated initscripts, and most other packages
which have errata associated with them. The error I get when logging in as
non-root user on a console is:

"input in flex scanner failed"

If I log in as root and su (or su -) to the other account, all works well,
so it seems to not be an authentication problem.

The message is not from login, but rather from /lib/security/pam_console.so,
a PAM helper module used by /bin/login.

You most likely have a damaged configuration. The simplest fix is
to reinstall the pam package (pam-0.68-7 in Red Hat 6.1) using
	rpm -U --force pam-0.68-7.*.rpm
and see whether that corrects the problem. If not, you'll have to examine
your PAM configuration in /etc/pam.d/*. Look for random file corruption
that can occur when a machine is rebooted after a crash or from a sudden
power down.
