Welcome to the latest issue of Linux User & Developer,
the UK and America’s favourite Linux and open source
magazine.
Servers were once the sole province of
corporations and other large organisations. Now you’re
much more likely to see one in someone’s home – maybe
they’re running their own business with it and it’s dealing
with essential files and folders, web access and accounts,
or maybe they’re simply using it to serve files around their home
network. These days many more of us are doing that, and if you
want to get in on the action, then head to p18 where our experts
explain everything you need to know to upgrade an existing home or
SME server, or build one from scratch.
Of course, once you’ve got your server up and running, it’s a good
idea to have remote access to it, but you’ll need to make sure that’s
secure. Check out the tutorial on p38 to find out more about remote
administration using SSH, and the one on p48 to find out how you
can prevent SSH attacks and keep your data secure. Plus we have
guides to Bash scripting, .NET and programming in Go to help you
develop your skills further. On p52, we take an in-depth look at
Linux Mint, including a breakdown of the various versions and how
they compare, plus advanced tips and tricks to configure it to your
liking and to make sure it’s locked up tight. Enjoy the issue!
