This component provides a built-in SSH server for Jenkins. It’s an alternative interface for the Jenkins CLI, and commands can be invoked this way using any SSH client.

Note

This is unrelated to SSH Build Agents. In that case, the agents are the servers, and the Jenkins controller is the client. |
Enable the built-in SSH server in Manage Jenkins » Configure Global Security.
System properties can be used to configure hidden options. These are generally considered unsupported, i.e. may be removed at any time.
-
org.jenkinsci.main.modules.sshd.SSHD.excludedKeyExchangesis a comma-separated string of key exchange algorithms to disable. By default, this disables SHA-1 based algorithms as they’re no longer considered safe. Use an empty string to disable no algorithms. The names of supported, enabled, and disabled algorithms can be viewed using the loggerorg.jenkinsci.main.modules.sshd.SSHDduring initialization on the levelFINE. -
org.jenkinsci.main.modules.sshd.SSHD.excludedMacsis a comma-separated string of HMAC algorithms to disable. By default, this disables MD5 and truncated SHA-1 based algorithms as they’re no longer considered safe. Use an empty string to disable no algorithms. The names of supported, enabled, and disabled algorithms can be viewed using the loggerorg.jenkinsci.main.modules.sshd.SSHDduring initialization on the levelFINE.
Defines the SSH public key user property and provides related API for Jenkins plugins.
