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". REPORTING BUGS
