Activate or deactivate the SSH server (2024)

Activate the SSH server

The SSH server is deactivated by default in Bitnami virtual machines. However, some applications (like GitLab) require SSH access to import code repositories.

To activate the SSH server, execute the commands below at the server console:

Debian

$ sudo rm -f /etc/ssh/sshd_not_to_be_run$ sudo systemctl enable ssh$ sudo systemctl start ssh

Ubuntu

$ sudo mv /etc/init/ssh.conf.back /etc/init/ssh.conf$ sudo start ssh

Once enabled, configure key-based authentication or password-based authentication and then connect to the virtual machine over SSH.
