Hi all, I have tried a number of methods to connect to a Mac slave and have had no success.
My master is also a mac and it's called dhcp151178. The slave I'm trying to connect to is called pelham. These of course are machines on my internal network. The first method I tried was "Launch slave agents on Unix machines via SSH". It looks like the master can connect to the slave via ssh but then I get the following (excerpted; full stack traces at end of message): java.io.IOException: Remote call on pelham failed ... Caused by: java.lang.InternalError: Can't connect to window server - not enough permissions. Then I tried "Launch slave agents via Java Web Start" And on the slave I navigated to http://dhcp151178:8080/computer/pelham/slave-agent.jnlp This gave me: java.lang.Exception: The server rejected the connection: Unauthorized access at hudson.remoting.Engine.onConnectionRejected(Engine.java:257) at hudson.remoting.Engine.run(Engine.java:232) Also, based on the following post: http://stackoverflow.com/questions/11824486/setting-up-a-hudson-slave-on-windows-xp I tried downloading the jnlp file from the URL above, replacing all instances of 'localhost' with 'dhcp151178' and launching the jnlp with javaws, this either gives me no console output at all (but the slave agent gui says Terminated) or it says: ... Exception in thread "main" java.lang.InternalError: Can't connect to window server - not enough permissions. I tried starting in headless mode, both as jenkins and as my regular admin user. I did this on the slave: java -jar slave.jar -jnlpUrl http://dhcp151178:8080/computer/pelham/slave-agent.jnlp Apr 30, 2013 5:19:02 PM hudson.remoting.jnlp.Main$CuiListener <init> INFO: Jenkins agent is running in headless mode.

I'm not sure how to set up "Launch slave via execution of command on the Master" because I can't find much documentation for that. So I'm stuck. I was able to set up a windows slave so I know that it is possible. But the Mac slave does not want to start. Can you help?
