Congratulations! You have successfully installed MCollective on your Elementary OS system. Now you can use the MCollective client to control your servers and execute parallel jobs.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
