While seeking for a nmap script that reports those times, I stumbled upon hping3 and the command I was seeking for: hping3 -p 22 -c 1-S server.domain.com Which returns almost the same info back (not the same as ping, but usable). I'm seeking for a way to have hping3 to talk like ping, but I'm afraid I have to create a script for it. -- Toni Van Remortel Linux System Engineer @ Precision Operations NV +32 3 452 92 26 - [EMAIL PROTECTED] ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
