[Samba] Sniffer techniques

[John Schmerold]

As the group knows, I'm having compatibility issues with a critical
database application. It's been wisely suggested that I monitor the
line to see what's up. Problem is: I've never done this before &
suspect others like me are not familiar with these techniques.

I did find an old LinuxWorld article http://tinyurl.com/yrjurx however
I help thinking there is more on the top.

Anyone find one or more how-tos especially enlightning?
