How to use ipgrab

I am trying to use ipgrab to determine what a machine does to identify itself on a network and also to find out what happens at the frame/packet level when you try to access a site on the local network or an outside host.  My question is if anyone knows the commands that will enable me to do this.  For example, I only want to get packet  information when I try to access a site.  Right now I get packet info about not only myself trying to access sites but also other people trying to access my site.  I have tried the various command line options and can't seem to get what I want.  I would appreciate any help.  Thank you...

My suggestion is to use TCPDUMP (most likley similiar to ipgrap) in conjunction with a perl script or grep parsing output.  It would seem that the perl script would be a better way to go.  You might try asking in the perl area by posting example output and saying what you are trying to do.

For TCPDUMP look at:
ftp://ftp.ee.lbl.gov/tcpdump.tar.Z

Additionaly there is a tool that may do what you want that analyses the output from TCPDUMP and it is availible at:
http://www.ipsilon.com/~minshall/sw/tracelook/tracelook.html
Also check:
http://www.ipsilon.com/~minshall/
The parent page as it has some additional programs for analysing TCPDUMP output

Lastley:
If you want to run TCPDUMP at command line use:
# tcpdump -D -s 99999
to dump the Data of the packets to 99999 bytes (default is between 60 and 80)
