Re: I can't sniff my LAN

[Anthony Murabito <anthony () iol unh edu>]

Hi Darkk,

After taking a look at the site and the pictures,  it is evident you 
have a 10/100 Switch. If this switch does not have the capability of 
port mirroring (check your manual if possible) you'll have to try one of 
the previously suggested methods (buying a small switch that has this 
capability, or choosing an option listed in the previous wireshark link 
for capture setup).

Regards,

--Anthony
