+====== Trisquel on SDF VPS ======
+===== Introduction =====
+Trisquel is a distro derived from Ubuntu, modified to remove non-free software.  As an Ubuntu derivative, the VPS guides for running Ubuntu and Debian should also be valid for Trisquel.
+Reasons to run Trisquel:
+  * based on Ubuntu/Debian
+  * stable LTS releases
+  * active project since 2007
+  * endorsed by the Free Software Foundation
+===== Basics =====
+==== Root Login ====
+The default root login is root/root.
+The first thing you should do is to change the password by running `passwd` on the command line.
+<code>
+root@trisquel:~# passwd
+Enter new UNIX password:
+Retype new UNIX password:
+</code>
+However, you may encounter this error message:
+<code>
+passwd: Authentication token manipulation error
+passwd: password unchanged
+</code>
+All you need to do is reboot.
+<code>
+root@trisquel:~# reboot
+</code>
+Then ''[c] - Connect to your console'' again from the VPS menu to the root account and try changing the password again for root.
+After this, it is highly recommended to create a new user for normal activities and disable root login.
+==== New User ====
+You should add a new user account for regular use.  Replace ''<username>'' below with the username you want for the user account.
+<code>
+root@trisquel:~# useradd -m <username>
+root@trisquel:~# passwd <username>
+Enter new UNIX password:
+Retype new UNIX password:
+passwd: password updated successfully
+</code>
+The ''-m'' switch on ''useradd'' creates your home directory at ''/home/<username>''.  By default, this new user is also assigned to a new group with the same name as the user.
+Presumably, you need sudo privileges for this newly created user, so you would add this user to the “sudo” group so that it can run commands as root.
+<code>
+usermod -aG sudo <username>
+</code>
+===== Security Checklist =====
+  * Change the password of root user: ''passwd''
+  * Disable root access: ''/etc/ssh/sshd_config''
+  * Block unused ports: ''iptables''
+  * Change default SSH port: ''/etc/ssh/sshd_config''
