Unable to monitor http packets over the network

0

Hello, I have used WireShark to monitor our network for about 2 years now. Normally when we are at a very high bandwidth peak I will logon to my remote machine and do some packet capturing. Recently when I have loged in and tried to do some monitoring I am not able to see the HTTP address. I just see one IP now.

Under HTTP Requests by Server Address I see 239.255.255.250 which I see is used for UPNP.

How come I was able to look through all the web addresses before but I no longer can?

I don't know, but if I had to guess, I would say: because somebody changed the capture setup, which led to the situation where your capturing system does not see the traffic any longer. Example: Somebody modified (or restored) the switch configuration, which disabled the port mirroring, or somebody replaced the switch altogether, etc.

Thanks Kurt, I figured out that one of the ports changed on the switch and I had to redo the port mirroring. Once I changed that and fixed that back up things were good to go.

THanks for the help!
