Multiplexing SSH Connections with Control Master: Speed Up Deployments and Automation
The article discusses the benefits of using SSH ControlMaster for multiplexing connections to speed up deployments and automation. It explains how traditional SSH connections incur significant overhead due to multiple handshakes, especially in automated tasks. By utilizing ControlMaster, users can reuse established connections, drastically reducing connection times and improving efficiency.
- ▪Every SSH command opens a new TCP connection, which can lead to significant delays in automation tasks.
- ▪ControlMaster allows one SSH connection per host to be shared by subsequent operations, skipping the handshake process for additional connections.
- ▪With ControlMaster, connection times can drop to single-digit milliseconds, regardless of network latency.
