Thank you for all of your suggestions, and good ones they were! Specifically thanks to: Jesse Becker Bruce R. Zimmer Thomas Knox Tim Gallagher Jonathan Katz David Evans Michael Grice Ed Mitchell The problem turned out to be DNS reverse lookup related and is being corrected as we speak. Some suggestions that I received were: * General Monitoring tool, Big Brother : http://www.bb4.com * A useful script to monitor the network * DNS reverse lookup failure/timeout * Negotiation speed of the ethernet switch * Incorrect netmask/routing * Problem with the switch/hub routing * Packet sniffers * use truss Thanks much guys!!! The original post was: Our network is experiencing delays in connections from various machines to other machines on a consistent basis. I have snooped extensively and not found any reason for this in examing packets. My question is: Might you suggest a network monitoring tool that would allow me to deduce the cause of delay in packets? Specifically, I have machine a and b in lets say in chicago, front-ended by a firewall. I have machine d in detroit, front-ended by a router. When i telnet from a to d there is an immediate connection. When I telnet from b to d, there is a 76 second delay. Tony Brown Unix Administrator aerospan.comReceived on Fri May 18 21:30:58 2001
