A: This is a bug from jetty, you need to be as root on uluru and kill the process that run by jetty and it will automaticly restart itself.
e.g: ps -ef | grep jetty, then kill -9 process-id-number, you should find only one jetty process.
(the process-id-number is the number next to user root)
Q: What if ssh key permission got messed up and can't log in?
A: make sure the user's dir is set to 711 as well e.g: drwx--x--x 25 maven maven 4.0K Mar 29 16:26 maven
