mlisten
mlisten — display multicast pings from the ParaStation daemon psid(8)
Synopsis
mlisten [-dv?] [-m MCAST] [-p PORT] [-n IP] [-# NODES] [--usage]
Description
Display the multicast pings the ParaStation daemon psid(8) is emitting continuously. These pings are
displayed by spinning bars.
Each ping received from node N lets the Nth bar spin around one more step. For each node never received
a multicast ping from a '.' is displayed.
ParaStation by default no longer uses multicast messages. Thus, no multicast
messages will be ever received and displayed using the default configuration!

each received multicast ping is displayed.
