Document SSH connection multiplexing for production access#115
Merged
Conversation
Repeat SSH sessions to production (log checks, WP-CLI, fail2ban lookups) were paying full handshake cost each time. ControlMaster/ ControlPersist reuses an authenticated socket per remote user instead.

This documentation update introduces SSH connection multiplexing guidance to speed up repeated SSH and Ansible operations against production servers within Trellis workflows. It adds a new section to
trellis/provision/PROJECT-SETUP.mdexplaining how to configureControlMaster/ControlPersistsettings in~/.ssh/configso that subsequent connections reuse an existing authenticated session instead of renegotiating the SSH handshake each time. TheCHANGELOG.mdis updated to record this documentation addition. This change is purely additive documentation with no impact on existing scripts, playbooks, or automation behavior.Documentation and Developer Guidance:
PROJECT-SETUP.md, describing theControlMaster auto,ControlPath, andControlPersistSSH config directives and their effect on connection reuse.trelliscommands and Ansible playbook runs against production hosts by avoiding redundant SSH handshakes.CHANGELOG.mdto reflect the new documentation entry, keeping the change log aligned with recent additions to the provisioning guide.Files Changed:
