Things to do after installing Debian 9 “Stretch”

 

Debian Stretch

 

In this guide, we are going to see a list of few basic things to do after installing Debian Stretch.

One of the first things to do is to update the sources and then grant sudo access to the default user so that we don’t need to switch user as root to perform operations that require root access. Granting sudo access to users on Home PC’s is ok but granting sudo access to users in an office environment is not recommended.

 

Update The Source List

Note: I would like to let you know that in this guide, we are going to install software from the “contrib” and “non-free” repositories too.

Also we are going to add “contrib” & “non-freerepositories that are not 100% FOSS as per the Debian Free Software Guidelines.

  • contrib” – repositories include packages which do comply with the DFSG, but may fail other requirements. For instance, they may depend on packages which are in non-free or requires such for building them.
  • non-free” – repositories include packages which do not comply with the DFSG

If you want to use a installation that is 100% FOSS as per the Debian Free Software Guidelines then just don’t add “contrib” & “non-free” to the source list.

How to add/enable/start Uncomplicated Firewall (UFW) during startup in Linux

Uncomplicated Firewall (UFW) is a simple/basic host-based firewall configuration tool used to manage iptables in an easy way.  UFW supports both IPv4 & IPv6.

Most of the Linux distros comes without a firewall.  Some Linux distros comes with UFW installed in it but UFW is not enabled by default.

If you are not comfortable with configuring UFW using command line then you may install Gufw which is a GUI to manage Ufw.  But using this tool, you can only add rules or enable/disable the firewall.  To add/enable/start UFW during startup, you have to run commands as root or sudo.
