I apt-get updated the system this morning.  I now find that I can't
do anything that requires login authentication.  I noticed it when a
sudo attempt just hung forever.  Checking discovered that I can't
sign on as either root or a user, at any prompt including VT's (which
would rule out an X problem).  Any such attempt just hangs
indefinitely.

Everything else works fine.  I can open new xterms in my current X
session, for instance.  Load is low.

I'm afraid to reboot, because I might be permanently locked out.

Any suggestions?  I'm downloading a current Knoppix CD right now to
use as a boot disk if I can't get it bootable again, but that would
be very annoying.

Thanks.


You might try to ssh in; if the problem is in PAM, I believe different modules are used for ssh authentication than for console authentication. This won't really gain you anything except perhaps a new clue or two.
