Subject: [Ethereal-users] UDP Packets everywhere
Hi all.. I am new to Ethereal so please excuse my lack of knowledge. I am also unsure if this is the right list for this kind of question, if not can someone point me in the right direction??
A slow network lead me to install Ethereal and see if it could find the problem. When I did the first capture I saw 70% UDP packets all of which looked like the following:-
Source : 10.0.xxx.xxx (most PCs on our network)
Destination : 232.47.16.89 (always)
Protocol : UDP
Source port : 1117 (appears to be random, not always 1117)
Destination port : 47713 (always)
Length 71
Can anyone help? I have slowed it a bit by implementing filtering on our switch but while that stops the broadcasts it still slows the PCs. No viruses or spyware found either.
I have attached a text file with 2 packets exported from Ethereal.
Thanks
