ps aux shows process -:0 running with root priveleges


Interesting. The title says it all. Just wondering what the hell this is. Have been searching the filesystem for it and I'm pretty sure I'm escaping the characters correctly, but haven't found it. Any ideas?


openSUSE 10.1 on P4 (2.67 GHz) HP Pavilion zd7000 Notebook with 256 MB RAM.

Thanks

this is propably the init process, "your running kernel", kill it and your system will halt

No it doesn't. Better post the exact 'ps' line. Even better, having the PID, check with 'lsof -w -n -p $PID' and verify what files you find.

While this may not be problematic in this case I would like to warn for making the assumption that the argv[0] of a process has any relation to the process itself. Without going into rootkits and stuff, for a benign example of what I mean see 'man doexec'.

Thanks for the replies...

Here's the offending line of output:

$ ps aux
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
...
root 3028 0.0 0.3 3656 1636 ? S 07:41 0:00 -:0
...


This "COMMAND" seems very odd to me. Here's the output of lsof:



PID=3028
$ lsof -w -n -p $PID

What do you guys think? Is this even anything to worry about?

oh, sorry, this was really a quick shot, having new information and clearly reading the :0, I try another (imho much better) guess:

This is the kdm process spawned by init, awaiting your X-login...

Thanks for the info...I was just a little suspicious, seeing references to security-related stuff from lsof.

Cheers!

Maybe, at least very close -- to properly investigate this, you need to remember 2 things: the "tree" style output & that however dearly you love, & always use, the BSD forms/options w/ ps, the UNIX options are different & may be more useful in this case. Compare these partial outputs from ps auxf (BSD) & ps -ejH ("UNIX"):
Code:
TTY          TIME COMMAND
?            0:00 /usr/bin/kdm
tty7       201:22  \_ /usr/bin/X -br -dpi 100 -nolisten tcp :0 vt7
?            0:00  \_ -:0
?            0:00      \_ /bin/sh /usr/bin/x-session-manager
?            0:00          \_ /usr/bin/ssh-agent /usr/bin/dbus-launch ...
?            0:00          \_ kwrapper ksmserver
Code:
TTY          TIME CMD
?        00:00:00   kdm
tty7     03:21:38     Xorg
?        00:00:00     kdm
?        00:00:00       x-session-manag
?        00:00:00         ssh-agent
?        00:00:00         kwrapper
(Note: I have trimmed both lines & columns, including PID, PGID, & SID to get to the essence.)

I think that "-:0" is screen 0 of X Window System; or, perhaps, its root window.
