=head1 NAME B<pping> - parallel ping the nodes. =head1 SYNOPSIS B<pping> [B<-i>|B<--interface> I<interfaces>] I<noderange> B<pping> [B<-h>|B<--help>] B<pping> {B<-v>|B<--version>} =head1 DESCRIPTION B<pping> is a utility used to ping a list of nodes in parallel. B<pping> will return an unsorted list of nodes with a ping or noping status. B<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. =head1 OPTIONS =over 10 =item B<-i>|B<--interface> I<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. =item B<-h>|B<--help> Show usage information. =item B<-v>|B<--version> Display the installed version of xCAT. =back =head1 EXAMPLES =over 3 =item 1. pping all node1: ping node2: ping node3: noping =item 2. pping all -i ib0,ib1 node1-ib0: ping node2-ib0: ping node3-ib0: noping node1-ib1: ping node2-ib1: ping node3-ib1: noping =back =head1 SEE ALSO L<psh(1)|psh.1>, L<noderange(3)|noderange.3>
