InfiniPath fabric. It is to be run on a front end node, and requires specification of a
hosts file:

where hostsfile designates a file listing the hostnames of the nodes of the cluster,
one hostname per line. The format of hostsfile is as follows:
hostname1
hostname2

ipath_checkout performs the following seven tests on the cluster:
1. ping all nodes to verify all are reachable from the frontend.
2. ssh to each node to verify correct configuration of ssh.
3. Gather and analyze system configuration from nodes.
4. Gather and analyze RPMs installed on nodes.
