The drawback of fuser is that it gets too many things involved. E.g. it is observed that it got stuck on cifs kernel module. This change uses a cleaner way to remember the stunnel client proxy. Even when the xapi restarted unexpectedly, it can stop the remnant stunnel proxy and start a new one. Signed-off-by: Ming Lu <[email protected]>
Making it configurable can avoid the situation when the port conflicts with others, e.g. an external program from users. Signed-off-by: Ming Lu <[email protected]>
