|
|
||||||
# do not support ControlPersist in their SSH implementations. This is needed on the Ansible
|
|
||||||
# control machine to be reasonably efficient with connections. Thus paramiko is faster
|
|
||||||
# for most users on these platforms. Users with ControlPersist capability can consider
|
|
||||||
# using -c ssh or configuring the transport in ansible.cfg.
