stop users telnet

[Mike Egglestone]

Hi all...   I have a bunch of users on my linux box that have access to some samba shares.... ftp to their home directories....etc...   What do you suggest I do to stop them from accessing the system via telnet or ssh? (just in case some of them are curious....don't want them looking in /etc)   However... I still want myself to be able to login via telnet or ssh.... Can I block certain users from such access?   Thanks Mike
