Wireshark-users: [Wireshark-users] Display Filter frame - how do that work?
Hello,
today I made a trace and I wanted to see all the DHCPNAK.
For this I found a filter:
frame[282:3] == 35:01:06
It works perfect. But my question is how is this filter defined.
For example frame[282:3] == 35:01:02 would be DHCPOFFER.
So {282:3] must be then DHCP. But how is that defined? Is that an offset? some bit? just a fix list?
and what is 35:01:06.
Any help would be greatly appreciated.
thanx a lot and have a nice day,
cheers,
Juergen
