rmcpping
RMCPING(8) System Manager Commands RMCPING(8)
NAME
rmcpping - send RMCP Ping to network hosts
SYNOPSIS
rmcpping [OPTION...] destination
DESCRIPTION
rmcpping uses the RMCP Ping request datagram to elicit an RMCP Pong response from a remote host. The utility can be used to verify if a
remote host supports RMCP or IPMI. The initial starting sequence number will be randomized. rmcpping will return 0 to the environment if
it receives atleast 1 response from the remote host. Otherwise, it exits 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.
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".
