I use SSH in a terminal window many times during a day.
I remember reading about a way to reuse a single connection so that the TCP and SSH handshaking don’t have to happen every time I establish another request to the same host.
Can someone point me to a link or describe how to establish a shared ssh connection so that subsequent connections to the same host will connect quickly?
Thanks.
Answering my own question. Improving SSH (OpenSSH) connection speed with shared connections describes using the “ControlPath” configuration setting.
UPDATE: For connections that are opened and closed often add a setting like
ControlPersist 4hto your ~/.ssh/config. See this post about SSH productivity tips.
