Setup a Dropbear SSH Server on Bionic64-v8 and Bionic64-CE

To set up a Dropbear SSH server in Bionic64-8.0 and Bionic64-CE
The Bionic64 must have the Devx.sfs installed and recommend the 32 bit compatibility libraries as well but that can be optional.

I am getting the «The requested page could not be found.» message when clicking the link.
Perhaps this link is the correct one?

How to start sshd on Puppy Linux?
- SSH should be installed in all puppies by default. Despite the name, this is only the client part of SSH, which allows one to log in to a host computer running another OS such as Raspberry Pi, Ubuntu, Antix, etc. Confirm this installation by looking for the ssh_config file in /etc/ssh. It is not necessary to edit this file, although in some cases a change in permissions of this file may be required to run as server. If another Linux Distro (eg Ubuntu) is running an SSH server on the same LAN, you can test the operation of the Puppy as a client as per step 10. This is not essential because we can test the operation of the SSH-client on the local or host device as per step 8 as part of the setup.
- To run SSH as a server, one needs to install SSHD — the SSH Daemon Server, which listens at port 22 (or otherwise configured) for clients requesting access to the Host Secure Shell. The host software Openssh-server can be installed from the PPM. As of LX Bionic pup, the version is 7.6p1, and on earlier Tahrpuppies it is 6.6.1p1.
- After installation of Openssh-server from the PPM, open the main SSH folder found at /etc/ssh . This folder must have two config files: ssh_config and sshd_config , plus a file called moduli. In the likely event that the default sshd_config file does not exist, download the script from: https://github.com/openssh/openssh-portable/blob/master/sshd_config This script must be pasted into a newly created text file, or an existing shell script which is gutted, populated with the sshd script and then re-named. Permissions may need to be changed to make the file editable or accessible. Failing that, copy the file from another operating Linux distribution where SSHD is installed. However, it is better to start with a default script.
- The sshd_config file must now be edited to operate under Puppy Linux. From experience, some of the lines below in the script seem to be more critical than others, as indicated in the RHS (#) comments. Remove any “#” comment tags on the LHS of the lines listed below and edit as shown. Optional lines should be able to be left as comments as these are the default configurations.
