Gary: remember that, for the same reason, if you send a single \xff, you won't see anything on the other side (unless the bug you are exploiting is before telnet's protocol decoding). i.e. Suppose you are using your $t to control a remote shell, then if you want the shell to recieve a \xff you need to send two of them. And while we are on it, most ftps also implement a downsized version on telnet's protocol, and for exploiting an ftp bug, you always always need to send \xff\xff instead of \xff. gera --- for a personal reply use: geraat_private top spam and e-mail risk at the gateway.
