hi *, i made a mistake changing the owner for all the /bin subdirectory (i changed it for the user1 instead of root) and now i can't log as user1 neither i can make su - logged as user2. when i type 'su -' i get the message: su: cannot set groups: Operation not permited does any knows how to log as root inside a telnet (without rebooting the server)? or how can i get around this problem? thank's every one.
