hi
Hi I am looking for a complete guide for beginners to zdebug and tcpdump for checkpoint gateways
Just google it, bunch of links come up with useful flags.
Maybe you want to use cppcap instead of tcpdump. Have a look at sk141412: cppcap - A Check Point Traffic Capture Tool…
It uses pcap-filter(7) as syntax and has no hassle with SecureXL.
tcpdump is not a CP software 😉
sk100808: How to use " fw ctl zdebug" command
You may want to check out my 2021 CPX presentation here which summarizes the packet capturing options on Check Point:
This presentation was derived from my self-guided video series "Max Capture: Know Your Packets" which thoroughly covers all the packet capture tools including tcpdump along with fw ctl zdebug + drop as well. There are also free updates to the original class available here:
Max Capture Update 1: Taking "Triggered" Packet Captures
Max Capture Update 2: Debug Filter Battle -- fw monitor -F vs. fw ctl zdebug + drop
