I'm trying to setup a box to record web visits across my network, both by log file and real time. I am trying to use Dsniff, urlsnarf, and webspy to accomplish it, but I am having an issue.

Both urlsnarf and webspy sniff the traffic on the host machine but are unable to anything else from the network itself. All machines are wireless so I shouldnt need to ARP poison or MitM correct? I cant seem to find an answer on the forums anywhere, the only threads I can find that are similar are people on switched networks where they would need to MitM,
