The Hudson (HIPP) instances hosted by the Eclipse Foundation are located on a private, non-routable network that cannot establish connections to the Internet (except http/s downloads using Proxy). To connect your HIPP to an external slave, you'll need to perform some SSH wizardry:

* On your HIPP, create a job that will only run this shell script once. Edit as required.
+
 
+
    ssh-keygen -t rsa -b 4096 -C "CBI genie" -f ~/.ssh/id_rsa.cbi -N ""
+
    chmod 600 ~/.ssh/id_rsa.cbi.pub
+
    echo "Adding pub key to authorized_keys file to log into build.eclipse.org"
+
    cat ~/.ssh/id_rsa.cbi.pub >> ~/.ssh/authorized_keys
+
    echo "Copy this key to your remote server's ~/.ssh/authorized_keys file"
+
    cat ~/.ssh/id_rsa.cbi.pub
+
    echo "Creating config"
+
    echo "" >> ~/.ssh/config
+
    echo "Host build.eclipse.org" >> ~/.ssh/config
+
    echo "StrictHostKeyChecking no" >> ~/.ssh/config
+
    echo "Host external-slave" >> ~/.ssh/config
+
    echo "StrictHostKeyChecking no" >> ~/.ssh/config
+
    echo "IdentityFile ~/.ssh/id_rsa.cbi"  >> ~/.ssh/config
+
    echo "PubkeyAuthentication yes"  >> ~/.ssh/config
+
    echo "ServerAliveInterval 60"  >> ~/.ssh/config
+
    echo "ProxyCommand ssh -i ~/.ssh/id_rsa.cbi build.eclipse.org netcat %h 22"  >> ~/.ssh/config

    chmod 600 ~/.ssh/config

    echo

    echo "Finished setting up SSH config"

    cat ~/.ssh/config

* Copy the public key that appears in the console to the authorized_keys file of the remote server, as instructed.
+
* In Hudson's management, create a new slave node. Choose the option to "Launch slave via execution of command on Master".
+
 
+
* Use this command, replacing (projectname) with the name of your project and username with the external username. Sadly, I cannot get bash ~ or $HOME here.  If you want to make sure the slave jar is always the same version as the slave, make sure you hse the slave jar available from your HIPP instance.

    ssh -C -i /opt/public/hipp/homes/genie.(projectname)/.ssh/id_rsa.cbi username@external-slave "wget -qO slave.jar https://hudson.eclipse.org/cbi/jnlpJars/slave.jar ; java -jar slave.jar"
