Jitsi Meet: free video conferencing - https://jitsi.org/
External disk mountable on startup: /etc/fstab
In Terminal:
sudo apt install samba smbclient cifs-utils
Next, edit configuration:
sudo nano /etc/samba/smb.conf
After every configuration, the service has to be restarted:
sudo service smbd restart
This guide lists the steps in order to setup the environment for the hosting of a Flask-based app. I'm assuming the IT professional is starting from scratch and a fresh, clean install of Debian is in place.
1) Install sudo
Debian does not come with the sudo program so it has to be installed with apt install sudo.
2) Allow remote ssh:
In order to allow root account login via ssh, edit the sshd_config file. As root, type:
nano /etc/ssh/sshd_config
Add the following line to the file (at the end of the file, for example):
PermitRootLogin yes
…and restart the service:
service ssh restart
Add newuser (or whatever plain user) to sudoers:
as root, run: usermod -aG sudo newuser
The -aG option tells the system to append the user to the specified group. (The -a option is only used with G.)
PostgreSQL can be installed with:
apt install postgresql postgresql-contrib
PostgreSQL version: PostgreSQL 13.5
Change to user postgres:
su - postgres psql postgres=# create user soto with encrypted password 'password'; create database flask_db; grant all privileges on database flaskdb to soto; createdb postgres GRANT ALL PRIVILEGES ON DATABASE postgres TO postgres;
Exit and run as root:
nano /etc/postgresql/13/main/postgresql.conf
add:
listen_addresses = '*' # what IP address(es) to listen on;
Next, you also have to edit the pg_hba.conf file to control access at a finer grained level. The file path is, in my case: /etc/postgresql/13/main/pg_hba.conf
sudo apt install postgis postgresql-13-postgis-3 sudo -i -u postgres

Verify Java has been installed by checking its version:
java -version
Java is now installed!
sudo apt install tomcat9 tomcat9-admin
Enable Tomcat to start at system boot:
sudo systemctl enable tomcat9
Start the service with:
sudo service tomcat9 start
Confirm the service is running with:
sudo service tomcat9 status
If the service is running ok, a line saying active will be displayed.
wget https://sourceforge.net/projects/geoserver/files/GeoServer/2.20.3/geoserver-2.20.3-war.zip
Stop Tomcat before unzipping the files:
sudo service tomcat9 stop
Move the downloaded file to the webapps directory:
sudo mv geoserver-2.20.3-war.zip /var/lib/tomcat9/webapps
Navigate to the webapps directory:
cd /var/lib/tomcat9/webapps
Unzip the file:
sudo unzip geoserver-2.20.3-war.zip
If unzip has not been installed, use:
sudo apt install unzip
After installing Tomcat, type:
sudo nano /etc/tomcat9/tomcat-users.xml
Add the following three lines to the xml file:
<role rolename=“admin-gui”/>
<role rolename=“manager-gui”/>
<user username=“tomcat” password=“pass” roles=“admin-gui,manager-gui”/>
Reboot (or simply restart tomcat service):
sudo reboot
