How to exit ssh
Hi,
I have a script that runs ssh to multiple systems. It does the folowing :
ssh -f -T server1 "/sbin/init.d/logsurfer newstart"
Running it using the -f option at least the prompt gets back, running it without the -f the prompt does not even show up. You have to press <Ctrl> + c to get the prompt back. However in both cases the remote command succeeded.
Using the -f option only keeps the processes running in the process table.
Adding an exit to the command also does not work, even adding the exit in the script didn't work.
Anyone a suggestion about how to start a process on the other machine and getting a normal exit ?
I don't like to have many processes running when they already finished their job.

fence_brocade
FENCE_AGENT(8) System Manager's Manual FENCE_AGENT(8)
NAME
fence_brocade - Fence agent for HP Brocade over telnet/ssh
DESCRIPTION
fence_brocade is an I/O Fencing agent which can be used with Brocade FC switches. It logs into a Brocade switch via telnet and disables a
specified port. Disabling the port which a machine is connected to effectively fences that machine. Lengthy telnet connections to the
switch should be avoided while a GFS cluster is running because the connection will block any necessary fencing actions. After a fence
operation has taken place the fenced machine can no longer connect to the Brocade FC switch. When the fenced machine is ready to be
brought back into the GFS cluster (after reboot) the port on the Brocade FC switch needs to be enabled. This can be done by running
fence_brocade and specifying the enable action
fence_brocade accepts options on the command line as well as from stdin. Fenced sends parameters through stdin when it execs the agent.
fence_brocade can be run by itself with command line options. This is useful for testing and for turning outlets on or off from scripts.
