Hi, >How to disable telnet for a group of users? Define a group that you could possibly name 'badboys'. set the permissions on the telnet binary to be r-x---r-x and group ownership to be 'badboys'. Then, add all the members of this group of users to the 'badboy' group. What will happen is this: when checking execute permissions when the user invokes telnet, the checking will end at the first match (group). And since group has no permissions at all on this program, the 'badboys' member won't be able to execute it. All those who are not part of the group will still be able to execute the program. I hope this helps. Yves Lepage
