Possible to remotely terminate process by a user who isn't logged in?

[Special K]

I am trying to remotely log into a workstation but so far I have tried 5 of them and some user is running a process 'flch' (I have no idea what it is) on all of them that is eating up all the CPU time. The thing is, this user is no longer logged in to any of those machines. First of all, how can you specify that you want a process to continue running after you logout, and secondly, is there any way to remotely terminate the process of someone who isn't even logged in? rmproc and kill don't work...

reboot the machine, and install antivirus software

yeah...cause Solaris is a glut for virii and worms.


When you talk about logging in, are you saying local, into the X enviro? I would just script an ssh session to login, ps to find the process and kill it.

You can either use screen or nohup, if either of those are available. nohup is easier to work with, but is only for non-interactive processes.

So, kill -9 didn't work? Try renicing it.

Yeah, I'm logging in with SSH and an xwindow program.

I was reading the man entry for renice and it says you can only do that to processes you started unless you are a priveleged user, so I'm not sure if that would work.

This is on a box where you don't have root? Then there really isn't anything you can do, except to contact the person who does, and tell him to kill the process.

If you aren't root why are you concerned? Can't you just contact the SA, and tell him of any performance impact this other process is causing?

OK, now this guy is running 'flch' on every machine of a different lab, in addition to the first one, grrrr...

If this person is able to keep processes running after he logs out, does that mean he has some special priviledge? Or can any user do that?

Notify the administrator.

Any user can do it.
