ppping.1

SYNOPSIS

ppping [-h | --help]

pping {-v | --version}

DESCRIPTION

ppping is a utility used to test the connectivity between nodes in the noderange using ping. By default, ppping will return an unsorted list of the node pairs that are not able to ping each other, or a message that all nodes are pingable. More or less output can be controlled by the -V and -q options. ppping front-ends pping and xdsh.

OPTIONS

-s

Ping serially instead of in parallel.

-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.

-V | --verbose

Display verbose output. The result of every ping attempt from every node will be displayed. Without this option, just a summary of the successful pings are displayed, along with all of the unsuccessful pings.

-q | --quiet

Display minimum output: just the unsuccessful pings. This option has the effect that if all pings are successful, nothing is displayed. But it also has the performance benefit that each node does not have to send successful ping info back to the management node.

-d | --debug

Print debug information.

-h | --help

Show usage information.

-v | --version

Display the installed version of xCAT.

EXAMPLES

ppping all -q

Output is similar to:

blade7: node2: noping
blade8: node2: noping
blade9: node2: noping
devmaster: node2: noping
node2: noping

ppping node1,node2 -i ib0,ib1,ib2,ib3
