hi i'm interested in knowing as to how urls of the sites accessed from the comps on the intranet can be extracted using jpcap. I basically want to know, how i can implement a intranet crawler.
i'm planning to create an application that would keep track of all the URLs accessed using a PCs on a LAN. I basically intend to catch the DNS queries and extract information about the URLs from it.
I'm sorry, but this sounds fishy. You'll need to convince us that this is for an honorable purpose.
As an aside, URLs work on a much higher level in the protocol stack than DNS (which is used to resolve host names like www.yahoo.com to IP addresses like 69.147.114.210), so you won't be able to extract URL information from DNS queries.
