TCP Snoop & wrapper shell script posted
Hi ,
I have posted DTrace script to snoop tcp traffic and also provided a
wrapper script
for it to filter out unwanted traffic.
http://blogs.sun.com/roller/comments/raviswam/Weblog/tcp_snoop_using_dtrace
Please let me know if you have any feedback/comments on this.
Thanks
