Title: Message
Gregory,
Do you want to know how to filter the trace to only
capture certain MAC addresses?
If so use a capture filter; eg "ether host
12:34:56:78:9A:BC".
Do you want to know how to display source and
destination MAC address columns in the upper window?
If so then select Edit - Preferences. Click Columns,
click "Add New". Then select Column format "HW Src addr (resolved)" and enter a
column title of "Src MAC", repeat for "HW Dst Addr (resolved)" and then click
Save and restart Ethereal (apply doesn't appear to
work).
Do you want to know how to prevent ethereal from
decoding packets beyond the MAC address?
I don't know how to do this explicitly, but you can
always mung tethereal -V's output (IMHO one of the most useful features of
tethereal).
tethereal -V | perl
-e'$/="\nFrame";while(<>){print (/^(.*)Internet Protocol/sm)? $1
:$_}'
HTH,
Alistair

[Ethereal-users] Sniffing MAC Addresses
Can someone give me some
tips on how to sniff MAC addresses. It seems like once I get to where I
can sniff IP addresses, ports, and such, the MAC address has already been
pulled apart at a lower level. My question is more for programming a
sniffer generally, but not specific to Ethereal.
How, generally is it
possible to sniff MAC addresses?
Any input or ideas would
be greatly appreciated. Thanks.
