The problem is there are no absolutely reliable ways of differentiating telnet from any other socket application. Linux behaves a little differently if the target port is not the telnet port, thus making the signature unable to differentiate telnet from a legitimate mail transfer agent. With some clever use of banner messages, you could probably handle the linux case. -----Original Message----- From: Geldard Valle [mailto:[EMAIL PROTECTED]] Sent: Tuesday, July 30, 2002 7:35 PM To: [EMAIL PROTECTED] Subject: Telnet Abuse signature problem TO UNSUBSCRIBE: email "unsubscribe issforum" in the body of your message to [EMAIL PROTECTED] Contact [EMAIL PROTECTED] for help with any problems! ---------------------------------------------------------------------------- -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Any body knows why the RSKILL form "telnet abuse" signatures in the RS 7.0 don�t works whe the telnet sourse is a LINUX system ?
