Github allows for a local github instance. However the github plugin only works with github.com. It would be nice to have the URL to use be configurable in Jenkins to allow for local github use.
Please let me know if the snapshot in the linked ticket is suitable, if yes I will proceed to merge the changes into master and release a new version of the plugin.
Merged branch and triggered new release, it should be available from the plugin manager soon. Let me know if there are any problems.
