I often have the need to find out all the Linux computers that an individual user is currently logged into across a network. Is there a simple command or pipeline of commands that can be run to report this?

A good example would be that I need to reset a user's Gnome settings by moving aside all their "." files (.gnome* .gconf* .gtkrc* .metacity .nautilus Desktop). However, I want to make sure that the user is not logged into any other computer simultaneously. Running a command that would report all the host names that a single user is currently logged into would be really helpful.

Is there such a thing in the linux world or a custom script that someone might have written?

Thanks in advance for any help,

John

You should look into putting /home on automount...really, saves you a lot of work.

There's plenty of monitoring software that can tell you who's logged in where. Worse comes to worse, just write a script that ssh in to every system and runs a who, then parse the results.

Can you recommend some of the monitoring packages you mentioned?
