Ubuntu 17.10 - tools and configuration

Written by Mirabellette / / no comments

I bought a new computer last year and I had to choice to install a new operating system. I am waiting for Qubeos 4.1 (x.0 are most of the time fucked up).
I choice to use Ubuntu 17.10 because packages are quite new and it is easy to use. To get an operative system fully usable, I had to do configure it and do some trick to get it as I want.

You can find below some tools I installed and some configuration I did.

First of all, the first thing you had to know is Ubuntu 17.10 has Gnome installed. Unity was give up by Ubuntu Inc. Astonishingly, even if it is the first release with Gnome, it works pretty well.

Display full date to toolbar

I wanted to display the full date to my toolbar.

sudo apt-get install gnome-tweak-tool

Launch tweaks
Top Bar > clock > Date > Calendar > Show week numbers

An ebook reader

There is no ebook reader by default in Ubuntu 17.10. Calibre is the most famous of them.

sudo apt update && sudo apt install calibre

Network manager

Network manager is installed on Ubuntu 17.10. I don't really like it because it changes your configuration. I try to disable these modifications in order to have a better control.
Randomize your MAC network address
Ubuntu allows by design to generate a random network MAC address at each network connection. It is a basic privacy settings which could help you to prevent mac address ban or to increase the difficulty to track your habits.

vim /etc/NetworkManager/conf.d/30-mac-randomization.conf
[device-mac-randomization]
# "yes" is already the default for scanning wifi.scan-rand-mac-address=yes

[connection-mac-randomization]
ethernet.cloned-mac-address=random
wifi.cloned-mac-address=random

To be sure if works well,

ifconfig && service network-manager restart && sleep 5 && ifconfig

The mac addresses from your ethernet interface and wifi interface must be different from the first ifconfig result displayed.

Disable automatic update of /etc/resolv.conf
When you want to use a specific dns, you have to modify /etc/resolv.conf. NetworkManager modifies this file each time it started. To avoid that:

vim /etc/NetworkManager/NetworkManager.conf
[main]
dns=none

service network-manager restart

To be sure if works well,
cat /etc/resolv.conf
The previous /etc/resolv.conf must be displayed.

Disable the DNS resolver
Ubuntu comes with his own resolver integrated in Systemd, I don't need it.

systemctl disable systemd-dns
systemctl stop systemd-dns

Speed test in command line

Sometimes it could be useful to measure your bandwidth in CLI.

sudo apt install speedtest-cli
speedtest-cli

Show display picture from others components (usb key, sd cards)

By default, Nautilus shows miniature only from local computer. It could be unconvenient when you have a usb driver which contains pictures. To enable this feature for all devices:
open nautilus (files) > preferences > search & preview > thumbmails > all files

Show information system

If you want to find some information about your own system configuration.
