# How to enable ssh access on the NovaSeq X Series

The NovaSeq X System runs on Oracle Linux OS which has the ability to allow ssh for remote access.

Users can follow the below steps to enable ssh access on the NovaSeq X instruments:

1. Log in as ilmnadmin.
2. Enable and start SSH service using the commands:

sudo systemctl enable sshd

sudo systemctl start sshd

3. Check status is online and running:

sudo systemctl status sshd

4. Check if firewalld is running:

sudo systemctl status firewalld

5. Enable SSH port (default 22):

sudo firewall-cmd --permanent --add-service=ssh

6. Reload firewall to apply changes:

sudo firewall-cmd --reload

7. Verify port 22 is open:

sudo firewall-cmd --list-all

If user still can't ssh into the instrument, then further changes need to be made on the user's side/network.
