I love the concept of tcpdump however I can not seem to master it.
I get all this "arp" trash on the screen.
How do I "tcpdump not 9 -i eth0" so I do not get all the arp stuff.
I am trying to build a firewall and can not get past the tcpdump.
I am sitting here so I am making this 500 points. I may ask a few other questions but would like to get this resolve soon.
using tcpdump, I want to filter out the 90% of the crap that does not pertain to my firewall filtering.
