Restricting a user

Jees Joy — Mon, 26 May 2008 16:57:41 GMT

hi Friends,

I want to restrict a user to use only some specific commands and not to move from his home folder.

I tried rbash, but there he have a facility to access sh, which infact gives no result for my answers.

Is chroot good in this scenario, in that case could somebody suggest me how can i implement chroot only on one specific user.

Please help me freinds.

Thanks In advance
Jees

Can you explain why rbash is not a solution to you? How can access sh?

rbash is not solution because, user can give the command sh and get the full privilage, the only option to restrict the user is by changing his ENV variables, but how can we change the env vairable permenantly for one particular user alone.
