Change SSH port on Ubuntu 22 using Ansible
After updating Ubuntu 22.10 SSHd uses socket-based activation.
As a result, the sshd configuration port does not affect the listening port.
To change the port, we need to perform the following tasks:
- name: Create config folder
file:
path: /etc/systemd/system/ssh.socket.d
state: directory
recurse: true
- name: Create config file
copy:
dest: /etc/systemd/system/ssh.socket.d/listen.conf
content: |
[Socket]
ListenStream={{ custom_ssh_port }}
- name: Reload systemd manager
systemd:
daemon_reload: yes
- name: restart ssh
service:
name: "ssh"
state: restarted
- name: Update connection port
set_fact:
ansible_ssh_port: "{{ custom_ssh_port }}"
