Wireshark-users: Re: [Wireshark-users] Fwd: Cannot receive all packet from different cpu.
Hubs are getting hard to find everywhere - in the US, Ebay is one
source. For the last year I've been collecting every hub I see (both 10
and 100) at junk stores, yards sales, even friends throwing them away
because they are "upgrading" to switches. Anyone who may even have to
troubleshoot a network should do the same. The has to be some old hubs
in your country somewhere....
For your immediate problem, could you install Wireshark on CPU
192.168.1.105 <http://192.168.1.105/>? If not, then I don't know of a
software-only solution to your problem.
Good luck,

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,
