I like to monitor the traffic that is exchanged between all the = computers, and capture and display them on a console computer. Since I'm using a switch, I will not be able to see the traffic and also the switch is a = 3com superstack II -3300 which can only monitor one port at a time, so that option is out also. I like to know how I can setup the pool of bsd computers, so that they send a copy of whatever packet they receive to = the console computer so that I can capture and graph it using a utility like etherape. thanks for your help, ~koroush To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message -----------------------------------------------------------------=0A= ATTENTION:=0A= The information in this electronic mail message is private and=0A= confidential, and only intended for the addressee.
