IPMIPING(8)							  System Commands						       IPMIPING(8)

NAME

       ipmiping - send IPMI Get Authentication Capabilitiy request to network hosts

SYNOPSIS

       ipmiping [OPTION...] destination

DESCRIPTION

       ipmiping  uses the IPMI Get Channel Authentication Capabilities request datagram to elicit an IPMI Get Channel Authentication Capabilitiesl
       response from a remote host. The utility can be used to verify if a remote host supports IPMI. The initial starting sequence number will be
       randomized.   ipmiping will return 0 to the environment if it receives atleast 1 response from the remote host. Otherwise, it exists with a
       value of 1.

OPTIONS

       The following options are available

       -h     Output help menu.

       -V     Output version.

       -c count
	      Stop after sending count packets.

       -i interval
	      Wait interval seconds between sending each packet. The default is to wait for one second between each packet.

       -I interface address
	      Set source address to specified interface address. Argument may be numeric IP address or name of device.

       -t timeout
	      Time to wait for a response, in seconds. Default is five seconds.

       -v     Verbose output.

       -s num Specify an initial starting sequence number. The default is to use a random initial sequence number.

       -d     Turn on debugging.

       -r version
	      Specify IPMI version. Available options are "1.5" and "2.0". Default is to use "1.5". Note that packets will always be sent with the
	      IPMI  1.5  protocol,  but  IPMI  1.5 vs IPMI 2.0 relevant fields will be communicated in the Get Channel Authentication Capabilities
	      datagram depending on user choice.

KNOWN ISSUES

       It has been observed that some remote BMCs can get "confused" and delay packet responses if duplicate packets (with duplicate sequence num-
       bers) are sent in succession very quickly. There is no known way to cleanly deal with a "confused" BMC other than the wait awhile.

       Unlike ping(8), local network devicess (e.g. 127.0.0.1) cannot be "pinged".
