Hi, Using Ansible, which takes advantage of ssh's ProxyCommand, I realized I couldn't make the ControlPath unique in every situation: If two hosts share the host-port-user in 2 different subnets, you end up with the same socket name, and there is no %(?) option to differentiate them. For example, user@10.0.0.2:22 via both machineA & machineB are different, but used sequentially quickly, there is no way for me to make the ControlPath argument unique while still reusing the connection for speed. So this is more of a feature / idea: Could an argument like %C (hash) be introduced, but one that would hash other options outside of %l%h%p%r, so that connection changing options like ProxyCommand are taken into account and make the socket name unique? That way ssh would have a way to create sockets that are unique per connection, including ProxyCommand, ProxyJump, etc, thus preventing wrong socket reuse. Cheers!
