Description

The SshFenceByTcpPort class assumes that netcat (nc) and fuser will be available on the ssh target. fuser is in /sbin and is probably always installed, but I've definitely seen CentOS boxes without netcat installed. We could force installation by listing it as a package requirement, which I suspect would be a good thing.
