     3Support team members [wiki:support-team/all-servers-root-access with root access on all servers] can help with running operating system updates (`apt-get update && apt-get dist-upgrade`).

     5Using freepuppet, there are two ways to do this:
     6
     7 * Upgrade one or more servers serially:
     8{{{

     10freepuppet-helper au:mosh
     11}}}
     12 * Upgrade multiple servers simultaneously:
     13  * Ensure you have cluster ssh installed:
     14{{{
     15apt-get install clusterssh
     16}}}
     17  * Use freepuppet helper. The following example will open a series of 12 simultaneous ssh connections to mosh servers. There will be one window to type a command that will be executed on all servers at the same time. Type: `apt-get update` followed by `apt-get dist-upgrade`. Once it is complete on all servers, type: `exit`. Once all connections are closed, it will open the next 12 until all mosh servers have been opened.
