u're shell is fscked, or someone put /bin/nologin as r00t's shell. check
up /etc/passwd.

this is a standard message for nonexistant users. maybe someone messed
around with u're /etc/passwd, and got to delete r00t. since shutdown and
co. run with r00t privileges, when there's a setuid to r00t, the process
cannot get its owner's pid/gid, as there's nowhere to look; /etc/passwd
being the standard place to look, now not withstanding.

aw... this is not a virus. someone just screwed u're system in a major
way, when practicing commands. maybe someone just scrapped u're shell.
maybe its overtime to keep in mind that Operating As R00T Is Evil (tm).
atleast u dont get to change stuff u're not ought to.

Nikhil.
