Can a jenkins agent be configured by multiple controller instances?

Question

I'm trying to have a slave that is hooked up to two masters. However, when I run the Jenkins JNLP I keep getting socket errors. Has anyone had experience with this and been able to work around it?

I know that I can connect to the jenkins box on port 8080. (I checked).

Answer 1

you need to have two separate jar files and secret keys for two different masters. I am seeing only one in the question. Once you have got you can run them one after other so that same slave makes connection to two different masters. Also it is important to note that you need Java version > 7.
