SSTP is Microsofts Remote Access Solution (RAS) for PPP over SSL. It can be used instead of PPTP or L2TP, and is only available with Windows Vista/7 connecting to a Windows 2008 Server. The advantage of SSTP compared to PPTP and L2TP is that it cannot be easily blocked by firewalls since the traffic is transmitted over HTTPS on port 443.

In Ubuntu Linux we can connect to SSTP by using SSTP-Client project on SourceForge.

To install SSTP-Client on Ubuntu add PPA repository:

sudo add-apt-repository ppa:eivnaes/network-manager-sstp

Then update package list and install packages sstp-client, network-manager-sstp by commands:

sudo apt update
sudo apt install sstp-client network-manager-sstp

Package network-manager-sstp is used only on Linux with graphic interface, on console Linux You don’t need to install this package.

To convert .CRT certificate to .PEM certificate use command:

openssl x509 -in mycert.crt -out mycert.pem -outform PEM

To install Nextcloud on Ubuntu or other Linux use command:

sudo snap install nextcloud

After installation snap package check installation status

sudo snap changes nextcloud

To change default http and https ports use commands:

sudo snap set nextcloud ports.http=81
sudo snap set nextcloud ports.https=444

In Nginx proxy server configuration file change proxy_pass default port to 81:

Nextcloud’s automatic hostname detection can fail when behind a proxy; you might notice it redirecting incorrectly. If this happens, override the automatic detection (including the port if necessary), e.g.:

sudo nextcloud.occ config:system:set overwritehost --value="example.com:81"

Nextcloud and Nginx https proxy

If You use Nginx as https frontend and nextcloud as http backend – You neet co change /var/snap/nextcloud/20498/nextcloud/config.php insert the foloving lines:

  'overwrite.cli.url' => 'https://example.host',
  'overwriteprotocol' => 'https',

In Nginx http config file insert 301 redirect to https:

return 301 https://example.host$request_uri;

By default, PHP will use 128M as the memory limit. If you notice images not getting previews generated, or errors about memory exhaustion in your Nextcloud log, you may need to set this to a higher value.

If you’d like to set the memory limit to a higher value (say, 512M), run:

sudo snap set nextcloud php.memory-limit=512M

To set it to be unlimited (not recommended), use -1:

sudo snap set nextcloud php.memory-limit=-1

By default the cronjob interval is 15 minutes. To adjust it (say, 10 minutes) simply run:

sudo snap set nextcloud nextcloud.cron-interval=10m

To install “LAMP” – Apache, PHP, MySQL on Arch and Manjaro Linux do some steps:

First update Your operating system to latest version:

sudo pacman -Syyu

Apache

After updating Your system lets install Apache web server:

sudo pacman -S apache

Edit file /etc/httpd/conf/httpd.conf, search and comment the following line:
# LoadModule unique_id_module modules/mod_unique_id.so

sudo nano /etc/httpd/conf/httpd.conf

Enable Apache service and restart Apache service using commands:

sudo systemctl enable httpd
sudo systemctl restart httpd

Verify Apache status by command:

sudo systemctl status httpd

PHP

Now install latest version of PHP:

sudo pacman -S php php-apache

After installation we neet to configure out PHP.
Edit file: /etc/httpd/conf/httpd.conf

sudo nano /etc/httpd/conf/httpd.conf

Find the folowing line and comment it:

#LoadModule mpm_event_module modules/mod_mpm_event.so

Also uncomment or add the line:

LoadModule mpm_prefork_module modules/mod_mpm_prefork.so

Then add the following lines at the bottom of configuration file:

LoadModule php7_module modules/libphp7.so
AddHandler php7-script php
Include conf/extra/php7_module.conf

PHP installed. Now create index.php file in Apache home directory to check that PHP is installed correctly:

sudo nano /srv/http/index.php

<?php
phpinfo();
?>

Restart the PHP service:

sudo systemctl restart httpd

Go to http://127.0.0.1/ and check that Apache server with latest PHP version installed on your Manjaro Linux:

MySQL MariaDB

Install MySQL Server:

sudo pacman -S mysql

Initialize the MariaDB data directory prior to starting the service:

sudo mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql

Enable and srart MySQL service:

sudo systemctl enable mysqld 
sudo systemctl start mysqld

Check that MySQL service installed and work correctly:

sudo systemctl status mysqld

After installation MySQL You need to setup root user and password:

sudo mysql_secure_installation

To install Skype on Arch or Manjaro Linux open terminal and clone latest stable Skype repository:

git clone https://aur.archlinux.org/skypeforlinux-stable-bin

Go to ~/skypeforlinux-stable-bin/ directory and build the AUR package:

cd skypeforlinux-stable-bin/
makepkg -s

When finished the result should be the newly build Skype package ready for the installation:

ls *pkg.tar.xz
skypeforlinux-stable-bin-8.59.0.77-1-x86_64.pkg.tar.xz

Using the pacman command install Skype package. Replace the package name suffix with the Skype version you have compiled previously:

sudo pacman -U --noconfirm skypeforlinux-stable-bin-8.59.0.77-1-x86_64.pkg.tar.xz

That’s all, the Skype installation is now completed. Use the Start menu and search Skype shortcut in Programs->Internet:

or simply start it from terminal:

skypeforlinux

Install Dropbox on Arch based Linux systems is very simple. First of all make sure that on Your system installed GIT, if not install git by command:

*If you already installed git , you don’t no need.

Now clone Dropbox git repository:

git clone https://aur.archlinux.org/dropbox.git

Go to Dropbox folder:

cd dropbox/

And compile the code by command:

makepkg -si

It’ll take some time so wait for it. If fails to build gpg key then just copy the key and type:

gpg --recv-keys 

Then again press makepg -si.

First remove old version of youtube-dl if installed:

sudo apt-get remove youtube-dl

Next install latest version of youtube-dl and install it:

sudo wget https://yt-dl.org/downloads/latest/youtube-dl -O /usr/local/bin/youtube-dl
sudo chmod a+rx /usr/local/bin/youtube-dl

If you have an error such “/usr/bin/env ‘python’ no such file or directory youtube-dl” – thats meen than you does not have installed python, or you install python3. Install python by command:

sudo apt install python-minimal

Or you can start youtube-dl with python3:

python3 /usr/local/bin/youtube-dl

Or you can create symbolic link python3->python with following command:

sudo ln -s /usr/bin/python3 /usr/local/bin/python

Якщо на комп’ютері встановлено декілька операційних систем, по замовчуванню завантажувач Grub завантажує першу операційну систему в списку.

Щоб змінити порядок завантаження операційних систем відкрийте файл

/etc/default/grub

Знайдіть рядок

GRUB_DEFAULT=0

Та змініть цифру 0 на номер операційної системи у вашому списку. (Нумерація рядків починається з 0)

Збережіть зміни в файлі та обновіть налаштування Grub

sudo update-grub
