Wireshark-users: Re: [Wireshark-users] Fwd: Cannot receive all packet from different cpu.
Hi,
Your problem is the switch - it's designed not to send all packets
to all ports. A few years back I went looking for a way to force the
switch to do this. I had the same Linksys (maybe an older one), the
famous wrt54g. I never found a way.
Your simplest solution is to go to Ebay, buy a cheap old hub (NOT a
SWITCH!) and attach both your PCs and the wrt54g to the hub. Make sure
you get 1 10Mb hub, not a 100 - IIRC the Linksys will only do 10. The
hub will forward every packet out every port, and you'll catch them all
with Wireshark.
Someday I'll write up my proof that Ethernet switches not only make
troubleshooting hard, they also slow down SOHO networks when compared to
hubs. But that's another story.
Hope this helps,
-JB-
