Hi guys,
im pretty new to java and jenkins and also new to this list (I'm a C# guy). But I have a question.
At the moment I try to start a jenkins node as a background service on a ubuntu machine. For that I have written a littel init script
jenkins.node.sh that works pretty fine as long as the user that runs jenkins
$juser in my script is root. But when I switch the user to my builduser (as shown in the
jenkins.node.sh) I get following exception when starting the node in my logfile and the node is not connected to the master:

Well, for sure this is a permission problem. But what permision do I need to set for waht user?
Im running Jenkins ver. 1.475 on my master. My slave is a Ubuntu 12.04 server amd64 with openjdk-7-jre-headless.
And this is what I get when I try to start it from comandline without my script:
