tcpdump is pretty frickin' sweet right? What with its metadata,
hex dumps and more, it's really bleeding useful for anyone who has
to troubleshoot anything that talks over a network (which, let's
face it, is everything these days).
Sure would be nice if it did colors though...
tcptrace to the rescue!
It's Perl, but it doesn't need any modules, just perl herself.
To install tcptrace, just curl or copy the binary somewhere in
$PATH and chmod to taste
curl https://raw.githubusercontent.com/jhunt/tcptrace/master/tcptrace > ~/bin/tcptrace
chmod 0755 ~/bin/tcptrace
Use it like tcpdump!
tcptrace -i lo port 5432
Enjoy the colors!
