Restrict the running of every app apart from Telnet,Ping ....

[lynxus]

Hi guys,

I have a server that people in my company SSH to so they can run pings , telnets etc from it.

I currently create them an account ie:
useradd blaa
passwd blaa

And then let them login.

However they can cd, ls, rm ,mkdir , vi , etc

How can I restrict these users apart from ROOT and maybe myself to only run programs like:
telnet
ping
traceroute

?

Any thoughts on the easiest way to do this ( Im good at linux, but not great... )


Thanks
L

Change the rights of the programs. Remove the execution rights for others.
chmod o-x file file file
You need this to do in the folders /bin , /usr/bin and /usr/local/bin
Tray it like: chmod o-x * and then chmod o-x ls bash rm mkdir vi
cd is a in bash build in command
