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 previos model in the final packet. For
example, to embed bgp inside tcp inside ipv4, do sendip -p ipv4 -p tcp -p bgp ....
Modules available at compile time:
ipv4 ipv6 icmp tcp udp bgp rip ntp
