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.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.
