Question: 10.21. ``You don't exist. Go away.''
Answer:

This is not a viral infection. It comes from programs like write, talk, and wall, if your invoking UID doesn't correspond to a valid user (probably due to /etc/passwd being corrupted), or if the session (pseudoterminal, specifically) you're using isn't properly registered in the utmp file (probably because you invoked it in a funny way).

#cat /etc/passwd
root:*:0:0:root:/:bin/sh
installer:x:0:0:installer:/:/bin/network-console

# id
uid=0(root) gid=0(root)

[Carthik Sharma (carthik)]

Right, for ssh, use the -l option to specify a valid username.

ssh xxx.yyy.zzz.sss -l carthik will let me login as carthik

Since you are running the command as root, it tries to login as root and begets the message it does.

ssh 192.168.1.7 -l carl
You don't exist, go away!

(just in case anyone was wondering)

[Ralph Janke (txwikinger)]

Does the user carl exist on the host 192.168.1.7 or the machine that you try to remote logon ?

Do you have any restrictions configured which users can logon via ssh on the remote machine ?

[Carl Karsten (carlfk)]

moot, cuz it looks like it got fixed.

for the record: user carl existed, but wouldn't have mattered - sshd will not reject a connection on just user name - it needs both user and pass.

[Colin Watson (cjwatson)]

For the record, the original bug here is the symptom of the libnss-files-udeb package being missing in the installer environment for some reason. This was probably transient.
