   1. via package manager

      1. Debian/Ubuntu
         # apt update
# apt install firebird3.0-server

      2. Other Linux, see firebirdsql.org

   2. via docker
      Recommended the jacobalberty/firebird image from DockerHUB
      https://hub.docker.com/r/jacobalberty/firebird
      https://github.com/jacobalberty/firebird-docker
      

2. Create QSoft specific ini file in the same directory as firebird.conf 
   (e.g. in Debian 10: /etc/firebird/3.0/)

   1. # nano firebird-qsoft.conf

   2. Insert specific config lines (see below: QSoft specific firebird conf)
      
      

3. Modify firebird.conf file
   insert into the first line: include $(this)/firebird-qsoft.conf

5. Test connection 
   
   1. on the server: telnet localhost 3050   
      
   2. from remote client : telnet <server.ip> 3050


6. Possible causes, if the connection is not working properly
   
   1. firewall exists on Linux server
      If required, modify firewall rules to allow communication 3050/TCP and 33050/TCP 
   2. SUP slowly started
      like above, possible Firewall restriction
   3. In some distribution, access is restricted only to localhost by default
      in this case, comment the line "RemoteBindAddress = localhost" in firebird.conf
