Do you use any web ui's for your Linux server? I'm comfortable managing my server using the command line, but I also want a graphical interface that shows an overview of what is running on the server, the way the resources are being used what containers are running and so on. Also file download uploads would be great to have.
What do you recommend which is light and resources and is suitable for less powerful servers with low ram?
So far these are the more interstating tools I've found: (they vary in functionality their provide)
You could use a hardware key for ssh with a passphrase protected key. I use a solo key v1 myself. There are even keys that let you enter a pin on the device instead of the computer, so you don't have to worry about key loggers. And you can set up Sudo to work with a key too.
Wait, wait, wait. If you want something publicly accessible most of the solutions in this thread would be a Bad Idea™️. Don't expose anything that could possibly make changes to the system to the Internet.
