swarm plugin: Cannot find tcpSlaveAgentListener

[grayaii]

Hi,
I'm using 1.6 of the swarm plugin and our jenkins version is 1.432.

I installed the plugin on the Jenkins master, but when I try to connect the
slave machine (windows XP) to the master, I get this error:

C:\>java -jar c:\temp\swarm-client-1.6-jar-with-dependencies.jar -master
http://[JENKINS_IP]:8080/jenkins -name ALEX_SLAVE -executors 1 -labels
ALEX_LABEL -password my_passWord -username my_userName

Discovering Jenkins master

Found 1 eligible Jenkins.

Any idea why this directory does not exist? How do I get it? I checked the
Jenkin's file system and it's not there. Am I missing a plugin or
something?

dang. Spoke too soon. I simple had to:
Under Manage Jenkins, enabled the "TCP port for JNLP slave agents" to be
random, and that allowed the slave to connect to Jenkins.

That got it working.
