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, and is therefore completely non-standard.

       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 (10 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.
