Can Anyone help me to open Port 636 as it has been already used by another application???

go into your firewall settings and open the port. but what do u mean by its already used by another application can u give us some output

If another app has the port open, then you don't need to open it; its open. But it is only open to the app that opened it.

What you need to do is find out what the app is that has got it open (something like 'netstat -pantu' should give you a clue...you probably want to feed the output into 'less' if there is too much).

You then need to do something about that app.

Once you have stopped the other app (if it is another app) from opening the port, then you should be able to open it. Of course it could be a previous invocation of your own port opening that hasn't cleaned up after it exited/failed.

Also grep ':636' might be helpful, putting them all together: The above is a little artificial, as it is very unlikely that you will need both grep & less.

What did you do?
What worked?
