Configuring SSH
2 minute read.
Last Modified 2022-05-11 11:36 EDTThe SSH service allows connections to TrueNAS with the Secure SHell Transport Layer Protocol. When TrueNAS is used as an SSH server, the users in the network must use SSH client software to transfer files with SSH.
Allowing external connections to TrueNAS is a security vulnerability! Do not enable SSH unless external connections are required.
To configure SSH, disable the service and click .
Configure the options as needed to match your network environment.
See SSH Screen
Remote systems could require root access to the system, but make sure to have all security precautions in place before allowing root access.
There are some additional options recommendations for the SSH service:
- Add *NoneEnabled no to the Auxiliary Parameters to disable the insecure none cipher.
- Increase the ClientAliveInterval if SSH connections tend to drop.
- ClientMaxStartup defaults to 10. Increase this value when more concurrent SSH connections are required.
Don’t forget to re-enable the SSH service on the Services page when all configuration changes are complete. To create and store specific SSH connections and keypairs, go to the System menu section.
