TLS, also known as Transport Layer Security, is a network protocol that uses SSL certificates to encrypt the network traffic which flows between a server and a client, or between a web server, such as Nginx server, and a browser. All data exchanged in between these two entities is secured and the connection cannot be decrypted even if it is intercepted using a technique such as by a man in the middle attack or packet sniffing. The certbot package software is the official client utility provided by Lets Encrypt CA that can be used in the process of generating and downloading free Lets Encrypt certificates in Debian.

Things to do after a fresh install of GNULinux. So, regardless of what distribution being used, there are things that I do after every single install I do, and I thought perhaps I would share some of them with you perhaps something I do is missing from your setup and you might like to include it I am going to leave out the things that you find in every other list. Download your favourite music player as this is redundant, and pointless to list. The list includes the following five suggestions increase audio quality, making sure the firewall is enabled,1. Increase audio quality. Im not going to get into the deeper explanation behind audio and its quality suffice to say I use expensive headphones, speakers, and every possible opportunity I have to enhance the quality of my sound. So, when I install a new OS, one of the first things I do is make sure that my tunes sound good for while Im following the rest of my setup. To do so, we need to edit a configuration file for Pulse. Audio. sudo nano etcpulsedaemon. In this, there are three lines we need to find resample method speex float 1 default sample format s. The last two lines are abovebelow eachother, but the first line is a little ways above them in the configuration file. Edit these, to look like thisresample method src sinc best qualitydefault sample format s. NOTE You MUST ensure that the is removed from all three, for this to work. After this is done, save and exit the configuration file, and then we need to restart Pulse. Audio pulseaudio kpulseaudio start. Aaaand voila Your music will now sound better than it would have previously. Youd be surprised. Make sure firewall is enabled. Most distributions tend to have UFW installed as the default firewall, but not all of them enable the firewall by default. Always always always, make sure you enable the firewall. The default home setting is usually fine for most people, just simply turn the firewall on, and youre done. However, if there is no firewall installed, youll want to install gufw which will also include UFW itself, as well as a graphical tool for it. Disable any unnecessary services. This one varies from distro to distro, on what needs to be disabled or not, but things like printer support are not needed if you dont own a printer, etc. Typically, GNULinux systems do not run a trillion services to shut down like Windows, but always good to look, and see. Most distributions and environments have a services list in the system settings. The Antergos Cinnamon one, looks like the photo above. Install Timeshift. Previously I wrote an article about how to install Timeshift into Linux Mint, but really I would advise installing it into any system you use, if its not included with the distro. Timeshift is almost crucial for someone like me, who cant run the risk of losing everything in the case of a crash or other mishap. Get it. Use it. 5. Install Clam. AV Clamtk antivirus.
