       ipsend - sends IP packets


       ipsend [ -dITUv ] [ -i <interface> ] [ -f <offset> ] [ -g <gateway> ] [
       -m <MTU> ] [ -o <option> ] [ -P <protocol> ]  [	-s  <source>  ]  [  -t
       <dest. port> ] [ -w <window> ] <destination> [TCP-flags]


       ipsend  can be compiled in two ways.  The first is used to send one-off
       packets to a destination host, using command line  options  to  specify
       various	attributes  present  in  the headers.  The destination must be
       given as the last command line option, except for when  TCP  flags  are
       specified as a combination of A, S, F, U, P and R, last.

       The other way it may be compiled, with DOSOCKET defined, is to allow an
       attempt at making a TCP connection using a with	ipsend	resending  the
       SYN packet as per the command line options.


       -d     enable debugging mode.

       -f <offset>
	      The  -f allows the IP offset field in the IP header to be set to
	      an arbitrary value, which can be specified in decimal  or  hexa-

       -g <gateway>
	      Specify the hostname of the gateway through which to route pack-
	      ets.  This is  required  whenever  the  destination  host  isn't
	      directly	attached  to  the  same network as the host from which
	      you're sending.

       -i <interface>
	      Set the interface name to be the name supplied.

       -m <MTU>
	      Specify the MTU to be  used  when  sending  out  packets.
	      This  option  allows  you to set a fake MTU, allowing the
	      simulation of network interfaces with small MTU's without
	      setting them so.

       -o <option>
	      Specify  options	to  be	included  at  the end of the IP
	      header.  An EOL option is automatically appended and need
	      not  be given.  If an option would also have data associ-
	      ated with it (source as an IP# for a lsrr  option),  then
	      this will not be initialised.

       -s <source>
	      Set  the	source address in the packet to that provided -
	      maybe either a hostname or IP#.

       -t <dest.port>
	      Set the protocol to the value given.  If the parameter is
	      a name, the name is looked up in the /etc/protocols file.

       -T     Set the protocol to TCP.

       -U     Set the protocol to UDP.

       -v     enable verbose mode.
