Port Monitoring

By snide3 ·
On my network I run a proxy server on the PDC and Exchange on the BDC. Lately I have problems with ports shutting down on me.

My Internet stops passing traffic on port 80 with the proxy server still running, I have to reboot my PDC to re-establish an Internet connection. Now, while all this going, on my Exchange server continues to pass email from outside my domain, I test this every time the Internet goes down.

Is there something (software) I can use to monitor these ports, like performance monitor or something else. I want this program to be able to keep a history of all it monitors during the nights, because it seems to happen when I am away.

use ethereal for free

with tcpdump for windows. If you use the tcpdump filters you can narrow it down to specific ports and keep logs, or log everything and then sort it (they can get pretty big though). There are a lot of ways to do this, etherpeek is a similar all purpose tool, but could be spendy depending on your budget. There are a bunch of port tools too, but if you haven't get ethereal and it will answer a lot of questions you never knew you had about your network :)

We use whats up to monitor a lot more than just one box. This is a great product - give it a look.

Make sure that you keep an eye on the event logs localy also - they might be able to tell you whats going on.

Good luck,
