Ansible: SSH Error: unix_listener: too long for Unix domain socket

Question

This is a known issue and I found a solution but it\'s not working for me.

First I had:

fatal: [openshift-node-compute-e50xx] => SSH Error: ControlPat         


        

Answer 1

Just to add more, as the error shows this problem generally happens when the control path is too long for Unix domain socket, hence, to specific to ansible.

You can easily fix this by updating your config file to use the %C format instead of %r@%h:%p as follow:

$ mkdir ~/.ssh/control 
$ vim ~/.ssh/config 
Host *
  ControlPath ~/.ssh/control/%C
  ControlMaster auto

More Detail: man ssh_config defines the %C format as 'a hash of the concatenation: %l%h%p%r'. And refer here.
