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!

Options

-d , --debug

Activate the debugging mode. This will disable the spinning bars. Instead a detailed message about each received multicast ping is displayed.

-m , --mcast=MCAST

Listen to multicast group MCAST. Set this to the value of MCastGroup in the ParaStation configuration file parastation.conf(5). The default is 237, which is also the default within psid(8).

-p , --port=PORT

Listen to UDP port PORT. Set this to the value of MCastPort in the ParaStation configuration file parastation.conf(5). The default is 1889, which is also the default within psid(8).

-n , --network=IP

Listen on the network interface with address IP. The default is to listen on any interface. IP is the IP address of the network interface in dot notation.

-# , --nodes=NODES

Display information for NODES nodes. The default is 128, i.e. 128 nodes.

-v , --version

Output version information and exit.

-? , --help

Show a help message.

--usage

Display a brief usage message.
