Hi Group Does anybody know how I can go about restricting logins (telnet) for other users besides the root user? I'm looking to restrict my dba's from logging in directly to the oracle account and would rather have them su to the oracle account from their individual logins. Also, is there a way I can log the "su" attempts made on my servers, bypassing the messages log?
