Ethereal Capture-Filter for web address filtering
Hello,
I guess this question must have been asked before but I haven't found any answers. My boss has told me to find out which web addresses within the company are surfed to when he is on holidays.
The network is handled by a w2k server. For the stations the server acts as gateway whereby it is forwarding internet traffic to a router which is connected to the dsl line. So every traffic passes the server. I installed Ethereal and played around a little bit. I already found out how to filter all traffic on port 80. But of course this only returns the data traffic between the two computers ip-addresses.
I guess I have to filter just the requests of the workstations to the dns server, haven't I? With this I could theoretically see which addresses are to be solved, am I right? How do I do this/which port do I filter for name resolution?
Thanks and best regards,
