> 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.
