Have you looked at siftr(4) or dtrace_tcp(4)?

Hi Kevin,
I am looking to enable traces/log messages (like syslog or
/var/log/messages) inside the codebase... any pointers for tcp/ip.
tcpdump shows what is going on wire - but I would like to trace code
internals...printk..
Thanks a lot!

Use tcpdump(1) and/or net/wireshark(5). See man tcpdump and pcap-filter for
usage details. wireshark can analyze files collected by tcpdump and dissect
the packets. It can also do packet capture, itself.

Hi,
Could someone please guide me on how to turn on tracing/log?
I would like to follow/track how packets go in/out of TCP code block...
Please let me know what knobs are available to achieve this.
Thanks for any pointers.
