Corrupted passwd file?
I think I have a dying hard disk; the only other option is
I was upgrading libc & gcc compliers (from potato) on my laptop
over a PLIP connection when I gradually started losing priviledges
to ftp and telnet into the machine. Once I logged out I couldn't
log back in, even as root. At the login prompt I get something
like "Incorrect password for 'UNKNOWN' on tty1." I can't even
reboot, since ctrl-alt-del just retorts maliciously:
"You don't exist. Go away."
So far I haven't even been able to get rescue/root floppies
to work: ("Unable to open console.") but that may just be due
to the corrupt disks I'm trying to salvage.
I get no other symptoms of a dying disk: the boot sequence seems
to go smoothly with no apparent corruption of the filesystem.
