ssh

Session persistence

Add the following Control* parameters to your OpenSSH client configuration file:

Host devbox
	Hostname x.x.x.x
	[...]
	ServerAliveInterval 3600
	ControlPersist 1h
	ControlMaster auto
	ControlPath ~/.ssh/control/%C

and create the directory for control sockets with secured permissions:

mkdir -m 0700 ~/.ssh/control

Note: %C is used to avoid path too long for Unix domain socket errors and is a hash of %l%h%p%r%j.
