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
