UnknownHost Exception with Linux master and window slave

[Varghese Renny]

Hi,
  I am using jenkins with master node as Linux 64 bit and slava node as windows 32 bit. When i do Launch slave agent i am getting error like UnknownHostException.
When i read some blogs i find that jdk version should be same. i changed it to same. Then i give Host name of slave machine as Node name .Still i am not able to solve this error.
Somebody please help....

ERROR: Unexpected error in launching a slave. This is probably a bug in Jenkins

java.net.UnknownHostException: SISBLRDKT108

Thanks in advance

Problem is resolved.i get connection to slave using jnlp.
I am using Tomcat application Server. But i have another doubt regarding whether my slave should be able to use same tomcat instance as master has used.
Please reply

Thanks in advance

How is a slave on a Windows machine using a Tomcat instance on a Unix machine?  For that matter, how is a slave using a Tomcat instance at all?  Slaves aren’t servlets, just the Jenkins server is.

 

If you mean that the slave is running a job that interacts with a Tomcat instance, whether that can be done against the same instance as the Jenkins server depends on the job, not the slave.  Even if the job is playing with the Tomcat instance that Jenkins in on, neither the slave nor the server will put two and two together and realize it’s operating on the same servlet container that the Jenkins server is on.  Certainly, if the job is doing something like bouncing the Tomcat server that Jenkins is on, that will totally screw things up, as in the middle of the job, the slave will lose connectivity with Jenkins and probably die.

Connect slave to Jenkins one of these ways:

• Launch agent from browser on slave

• Run from slave command line:

  javaws http://punctstxp64t1:8080/computer/geom_punctstw764vm11/slave-agent.jnlp

• Or if the slave is headless:

  java -jar slave.jar -jnlpUrl http://punctstxp64t1:8080/computer/geom_punctstw764vm11/slave-agent.jnlp
