MaxSessions
MaxSessions is a configuration directive used by the OpenSSH server to limit the number of concurrent, multiplexed sessions that can be opened over a single SSH connection after authentication. In OpenSSH, a single network connection can carry multiple channels, and each session channel can host a command, a shell, or other subsystems. MaxSessions caps the total number of such sessions per connection, helping to control resource usage and reduce the impact of abusive or misconfigured clients.
The directive is configured in the server's sshd_config file, typically /etc/ssh/sshd_config. Administrators set a numeric value
Impact and considerations: Setting MaxSessions balances usability against resource protection. A higher limit benefits users who
