ok so I made some headway ..added bit more awk filtering:

Code:
tcpdump -i T3501 -A ether host 00:1e:49:29:fc:c9 or ether host 00:1b:2b:86:ec:1b or ether host 00:21:1c:98:a4:08 and net 149.83.6.0/24 | grep --line-buffered -B 20 IBM-32 | awk '/IBM-32/ || ( /IP/ && /Flags \[\.\]\, ack/ )' | awk '/IBM/ {print $0} /IP/ {print "Source-IP= "$3}'

and the output is like:

Code:
Source-IP= 199.198.231.57.59033
E@.D..@.p.g......S.@.G.W$.....W{P....^....(..IBM-3278-2-E.CDC13117..
Source-IP= 168.108.167.244.50411
Source-IP= 168.108.167.244.50413
E..DL0..9....S.@.....W.G..W{$...P....9....(..IBM-3278-2-E.CDC13117..
Source-IP= 199.198.231.57.34947
Source-IP= 168.108.167.244.50411

So my nextt task is, how to do further filtering so that I end up with, e.g.:

Code:
Source-IP= 199.198.231.57.59033
IBM-3278-2-E.CDC13117..
Source-IP= 168.108.167.244.50411
Source-IP= 168.108.167.244.50413
IBM-3278-2-E.CDC13117..
Source-IP= 199.198.231.57.34947
Source-IP= 168.108.167.244.50411

Thnx
