Does anyone know of software that will monitor my Jetstream connection on a Cisco router? I did a search and have seen Ethereal referred, but I don't think it will work on my router.
I want to be able to have a report that filters ports, traffic destinations and if possible, connection to Windows 2000 Active Directory to allow for user usage.
I need this because the sites and ports accessed by users do not work if I put a proxy in between and I do not want to have a proxy.
I am looking at visualware at present.
regards

Marty

Ethereal is a network traffic monitor/sniffer and will log any traffic transmitted over a network that doesn't use a switch. An easy way to determine if ethereal will work on your set-up would be to use the Knoppix Linux disk from the October PC World.

Depending on how you set-up the ethereal capture will determine how large the file would be. You could easily run into GB of saved data over a very short period.

Ethereal will give you IP address connection info (ie from/to ) as well as any data that is transmitted. It needs to be used with caution.

If the router feeds a switch you might have to get the router doing the logging, or put a machine on a hub with the switch, so it can see all the traffic.
