Charlie,
Sounded interesting so I gave this a try on our test environment, with
the following config:
Host *
ControlMaster auto
ControlPath ~/.ssh/master...@%h:%p
Initially, all looked well, but then we started to see these:
Remote command execution failed: Control socket
connect(/var/log/nagios/.ssh/master-r...@192.168.100.100:22): Connection
refused
So you see this as well in your environment?
