NAME
       iplayer - A sniffer for building custom packets


SYNOPSIS
       iplayer	[ -blmnpt ] [-s spacing ] [ -c cnt ] [ -r file] [
       -i if ] [ expr ]


DESCRIPTION
       iplayer (pronounced ip_layer)  reads  and  parses  packets
       from the link layer through the application layer, dumping
       explicit header information along  the  way.  Its  primary
       purpose	is  for building custom TCP/IP packets and allows
       hex output to be formatted so it can easily be pasted into
       nasl  source  files  or	used by sendip. It is a shameless
       rip-off of ipgrab 0.8.2.


   Options
       -b     Buffer standard output. Useful  when  you're  redi-
	      recting output to a file.

       -s spacing
	      Set  hex	spacing.  0:  no  spacing  between  bytes
	      (sendip) 1:  a  single  space  (default)	2:  comma
	      delimited 0xnn (nasl)

       -l     Don't print link-layer headers.

       -n     Don't print network-layer headers.

       -p     Don't print packet payloads.

       -t     Don't print transport-layer headers.

       -c cnt Terminate after receiving cnt packets.

       -i if  Listen on interface if, e.g., eth0.

       -r file
	      Read a tcpdump capture file.

       expr   Berkeley	packet filter expression.  See tcpdump(8)
	      man page for details and examples.
