+<longdesc>fence_na is an I/O Fencing agent which can be used with the Node Assassin network power switch. It logs into device via telnet and reboots a specified outlet. Lengthy telnet/ssh connections should be avoided while a GFS cluster  is  running  because  the  connection will block any necessary fencing actions.</longdesc>
