ipsec_ikeping

IPSEC_IKEPING(8)						  [FIXME: manual]						  IPSEC_IKEPING(8)

NAME

       ipsec_ikeping - send/receive ISAKMP/IKE echo requests/replies

SYNOPSIS

       ipsec ikeping [--listen] [--verbose] [--wait time] [--exchangenum num] [--ikeport localport] [--ikeaddress address] [--inet] [--inet6]
	     destaddr [/dstport...]

DESCRIPTION

       Ikeping sends and receives ISAKMP/IKE echo request and echo reply packets. These packets are intended for diagnostics purposes, in a manner
       similar to ping(8) does for ICMP echo request/reply packets.

       At the time of this writing, the ISAKMP echo request/reply exchange is still an internet-draft (draft-richardson-ipsec-ikeping-00), and is
       therefore completely non-standard. The Openswan IKE daemon pluto does implement this draft, so ikeping can be used to test connectivity to
       an openswan ipsec server.

       Ikeping will bind to the local address given by --ikeaddress and the port number given by --ikeport defaulting to the wildcard address and
       the ISAKMP port 500. An ISAKMP exchange of type 244 (a private use number) is sent to each of the address/ports listed on the command line.
       The exchange number may be overridden by the --exchangenum option.

       Ikeping then listens for replies, printing them as they are received. Replies are of exchange type 245 or the specified exchange number
       plus 1.	Ikeping will keep listening until it either receives as many echo responses as it sent, or until the timeout period (5 seconds)
       has been reached. Receipt of a packet will reset the timer. The --wait option can be used to specify a different timeout period.

       If the --listen option is given, then ikeping will not send any packets. Instead, it will listen for them and reply to each request
       received.

       If the --natt option is given, then ikeping will set the socket to permit UDP encapsulated ESP packets. This is only useful in listen mode.
