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