NAME

       sendip - Send arbitrary IP packets

SYNOPSIS

       sendip [-v] [-d data] [-h] [-f datafile] [-p module] [module options] hostname

OPTIONS

       -d data
	      add  this  data  as a string to the end of the packet Data can be: rN to generate N random(ish) data bytes; 0x or 0X followed by hex
	      digits; 0 followed by octal digits; any other stream of bytes

       -f datafile
	      read packet data from file

       -h     print this message

       -p module
	      load the specified module (see below)

       -v     be verbose

       Modules are loaded in the order the -p option appears.  The headers from each module are put immediately inside the headers from  the  pre-
       vios model in the final packet.	For example, to embed bgp inside tcp inside ipv4, do sendip -p ipv4 -p tcp -p bgp ....

	      ipv4 ipv6 icmp tcp udp bgp rip ntp
