Concerning the FS, i was running the same version (1.456) for both masters and slaves, and it always worked well since each one launches a independent java process (some it doesn't matter whether they run from the same jar or not) How is running a different jar possible? The server should automatically download the current version of the jar files when starting via ssh. But when i moved to 1.518, it looks like there is some conflict (and i suspect the default port) when i launch two slaves, even with two different masters I thought you said it only happens when you start with your custom ssh script, not the internal ssh support.

Are you using the matrix based security in jenkins, and if so, is the Anonymous user allowed to connect/disconnect slaves?If you repeat this scenario, do you see your login name in the top bar of the web page as you disconnect? i never said i was running a different jar, i said i was running a different java process. I think it has to be a different jar if jenkins is starting it via ssh, because it will download it for you. Try setting up a different user with no jars at all in the target directory. do you have any documentation about jenkins slaves ? I'd like to know more about the default behaviour in that kind of situation No - but you could always poke through the source code. But, I would never have considered running two different masters for slaves in the same space concurrently in the first place. Why do you think they shouldn't conflict with each other, especially when they need different jars of the same name?Perhaps more to the point, why do you want to do this? Maybe there is a better approach to whatever it is you are trying to do. -- Les Mikesell lesmikes...@gmail.com -- You received this message because you are subscribed to the Google Groups Jenkins Users group.

By the way, i also noticed when using the built in ssh plugin, the slaves are launched by the anonymous account even if i created them with a specific admin user.

Can't launch 2 slaves (having two different masters) on the same machine
Hi everybody,
Ii'm using two servers, one for jenkins master, and one for the slave
instance
I'm using Jenkins 1.456 as a main stream version, and was trying to prepare
an upgrade to 1.518, so i just installed another jenkins master for testing
puropose, and defined different ports for each one (the main master and the
test master)
then i added a slave node to the test-master, and i had already a slave
node for the main master.
i launch each slave by calling a script through ssh, something like
ssh me@my-slaves-server '/home/me/ slave_test.ksh start'
and the script is calling slaves that way
nohup /.../JAVA-6/bin/java -Xms512m -Xmx1024m -Djava.io.tmpdir=/tmp -jar
/.../hudson_slave/jar/${HUDSON_VERSION}/slave.jar -jnlpUrl
http://${MASTER_HOST}:${MASTER_PORT}/computer/${SLAVE_HOST}/slave-agent.jnlp
The problem is, each time i launch the test-slave the main-slave goes
offline and i have this stack trace
ERROR: Unable to launch the slave agent for
my-slaves-serverjava.io.EOFException

What happens if you use the built-in ssh support instead of your own
script? And for testing, I'd start the slave as a different user for
the 2nd instance.

Re: Can't launch 2 slaves (having two different masters) on the same machine
Actually i did try it and it worked well. But i don't know exactly wich
slave jar was lanched, and i can't just abandon the scripts since they're
doing some other stuff (logging, restarting on fail ...etc.)
