Subject: tcpdump - Option II
In reply to: Anandan 's message, "Packet Capture" on 22:18:04 03/04/07 Sun

tcpdump - options II for Controlling how information is displayed.

The -a, -n, -N and -f options determine how address information is displayed. The -a option attempts to force network addresses into names, the -n option prevents the conversion of addresses into names, the -N option prevents domain name qualification, and -f option prevents remote name resolution.
The -c option restricts capture to one packet to or from the specified host.

Try with these:
#tcpdump -c1 host 192.168.9.44 (No option specified above)
#tcpdump -c1 -a host 192.168.9.44

#tcpdump -c1 -n host 192.168.9.44

#tcpdump -c1 -N host 192.168.9.44

#tcpdump -c1 -f host 192.168.9.44

-a option is the default.

-t and -tt options control the printing of timestamps. The -t option suppresses the display of the timestamp while -tt produces unformated timestamps.-t option produces a more terse output while -tt output can simplify subsequent processing, particularly if you are writing scripts to process the data.
