Starting a Hudson slave on a Unix machine without SSH

One great feature about Hudson is the support for distributed builds. Distributed builds can be used to absorb load or for specialized build jobs such as system or functional testing or automated deployments. In this article, we look at a special case - what happens when you need to start a Unix Hudson slave from the slave machine itself. The best way to start a Hudson slave on a Unix build box is to use SSH. This is very convenient (all you need is a valid SSH account on the slave machine), and can be initiated automatically as required from the Hudson master. However, in some organizations, SSH is not installed on the machines, which makes this approach impossible. If you can't use SSH, you can still start the slave by running a command on the command line. Hudson provides a special JAR file, called slave.jar, for this purpose. You can get this file from your Hudson server using a URL like http://buildserver.myorg.com/hudson/jnlpJars/slave.jar (where "http://buildserver.myorg.com/hudson" is the URL you are running Hudson on). To start the slave agent, you invoke the slave.jar file as shown here: java -jar slave.jar -jnlpUrl http://build.myorg.com/hudson/computer/test-slave/slave-agent.jnlp Of course, you will also want to stop the slave agent. A more complete script, that lets you both start and stop the slave agent, is shown here: #/bin/sh HUDSON_MASTER=http://build.myorg.com/hudson start(){ wget $HUDSON_MAS...
