Thank you all who replied!
Original Question:
I would like to use tcpdump on an Alpha Station 255/233 to monitor raw
ethernet packets.
>From the docs it appears that I need to rebuild the kernel using
doconfig, adding the line
options PACKETFILTER
to the config file before it will work.
Is this step necessary and has anyone had experience using tcpdump on
the Alpha Station?
This response came from Arnaud Valeix and contains all the necessary
steps to get tcpdump working.
