strange user name

[vti]

Hi
When i look for processes, sometimes i see different characters instead of usernames like i write down.

 1684 4036 0.0 16:59:31 ttypp 0:00.09
 31940 1684 0.0 16:59:44 ttypp 0:00.64

Any clue about what "" character means and how can i find out which user is that?

Thanks

your character was "escape" ( \0x1b )
could be a terminal problem ( ie one type set in TERM/TERMINFO, another on terminal emulator)

you can use lsof utility if you need to find who uses this terminal

or ps -t ttypp or something like that (see man ps )

I think the ps command gheist is telling you about is;

ps -ft ttyp*

You can use

ps -lp1684

(for PID 1684), so you will see the user ID as a number and then you can find the corresponding user in /etc/passwd.
