NAME

pping - parallel ping the nodes.

SYNOPSIS

pping [-i|--interface interfaces] [-f|--use_fping] noderange

pping [-h|--help]

pping {-v|--version}

DESCRIPTION

pping is a utility used to ping a list of nodes in parallel. pping will return an unsorted list of nodes with a ping or noping status. pping front-ends nmap or fping if available.

This command does not support the xcatd client/server communication. It must be run on the management node.

OPTIONS

-i|--interface interfaces

A comma separated list of network interface names that should be pinged instead of the interface represented by the nodename/hostname. The following name resolution convention is assumed: an interface is reachable by the hostname <nodename>-<interface>. For example, the ib2 interface on node3 has a hostname of node3-ib2.

If more than one interface is specified, each interface will be combined with the nodenames as described above and will be pinged in turn.

-f|--use_fping

Use fping instead of nmap

-h|--help

Show usage information.

-v|--version

Display the installed version of xCAT.

EXAMPLES

  1. pping all

     node1: ping
     node2: ping
     node3: noping
  2. pping all -i ib0,ib1

     node1-ib0: ping
     node2-ib0: ping
     node3-ib0: noping
     node1-ib1: ping
     node2-ib1: ping
     node3-ib1: noping
