I am unable to exit my script that uses ssh to login to a remote server

Good day,

I need help on resolving this issue. I wrote a script which logs to a remote server using ssh to run some commands. Upon exiting the remote server, the session just hangs. I can't even break (ctrl-c) the session. I tried adding zero (0) to the exit of the script but still it hangs. This happens after I run the java program on the remote machine. But if I just try to use the other options its fine, it exits with no problem.

Please help

You could kill the session. "ps -e | less" shows a stack of all processes, so your session should be near the bottom. Killing either ssh or the shell running ssh should do the trick. If kill doesn't work try "kill -9". This is a kludge but it should end the hanging.

Java is really dumb, make sure EVERYTHING is closed. If that program is yours, make sure that it's not leaving any file descriptor open or something like that. Java programmers usually don't care at all about producing clean code because they think that's a task for the garbage collector. Ssh will not close the session if there's an open file descriptor that was open by a Java program running on the background.

EDIT: Just like this:
