Thank you Swarfendor437.
I took a look but decided on Webmin and it sure gives a lot of help in a nice GUI way.
I can access it via localhost:10000 but now want to get it remotely from outside the LAN.
I have been advised that I should be careful and best to setup a SSH Tunnel.
Unfortunately at my Linux level its like building a ship to Mars !
The proper way would be to, instead, set up an SSH tunnel between your remote system and your actual system with Webmin on it, and NOT EXPOSE webmin to the Internet directly.
There are a number of evils in webmin which allow for limitless bruteforcing of the webmin interface with it exposed right to the 'net which makes webmin bad to expose direct to the Internet.
UNDER NO CIRCUMSTANCES should you have Webmin directly accessible on the Internet because of the security risk to you, your data, and your network. Strongly consider an SSH tunnel via SSH Key Auth and opening the SSH port instead and route traffic over the SSH tunnel to reach webmin instead.
I see this tutor. Does this seem easy and correct?
