Note that if you are on centos 6, the openssh version isn't new enough to support this feature.

  this is not true

    Yes it is. ControlPersist was introduced in openssh 5.6. Centos 6 ships with a patched version of 5.3.

      Both ssh and sshd I guess? Do both ends need to support the feature?
    • er0k 13y ago
      ah ok. ControlMaster and ControlPath are both supported though.
