Thanks LANOT! And below, the procedure written by Alejandro Sierra:
In this blog post we’ll learn how to install the GNC-A ingestion software (KENCAST FAZZT PROFESSIONAL CLIENT VERSION 9.2) on Debian 10.3.
First, some important notes:
- This procedure was tested on Linux Debian 10.x, which is the current stable version. If your system has a previous version, the update is advised.
- FAZZT v 9.2 currently doesn’t support Debian by default, and the procedure described here is different to the one used to install on Ubuntu, so if you still want to do it, do it at your own risk. You had been warned.
- In order to install FAZZT, is necessary to install Apache2 and the PostgreSQL Database, as shown on this procedure.
- It is mandatory to create an account called “fazzt”. This is required for the FAZZT database to work.
Why Debian?
- It is a very robust distribution with 25 years of experience, completely able to be used in servers.
- Usually it is updated faster than other distributions and have a wider base of packages and software.
- It’s not as friendly as Ubuntu but as efficient as CentOs.
PART I: PREINSTALL
Install Apache2 and PostgreSQL, as root:
# apt update # apt install apache2 postgresql
Create the user fazzt:
# adduser fazzt
Get the most recent installation file for CentOs from KenCast. In our case, we will use the following installer, provided by KenCast:
Fazzt-Professional-Client-rhel7-9.2.0.0-1.x86_64.rpm
Now, the most important part of the trick: use the Debian tool called alien to create a corresponding “deb” file.
If that is too complicated, by all means you can get ours from the following link:
fazzt-professional-client-rhel7_9.2.0.0-2_amd64.deb
PART II: INSTALLATION
Use the generated “deb” file to install the Fazzt Professional Client:
# dpkg -i fazzt-professional-client-rhel7_9.2.0.0-2_amd64.deb
Now, the “alien” tool did a very good but imperfect work, so you will have to do a couple of adjustments by hand. The Apache’s configuration and module files were installed in the wrong directory. Just copy them to the correct one:
# cp -p /etc/httpd/conf.d/S10-fsp.conf /etc/apache2/conf-available/S10-fsp.conf # cp -p /etc/httpd/conf.d/S60-fazzt-admin.conf /etc/apache2/conf-available/S60-fazzt-admin.conf # cp -p /etc/httpd/modules/mod_fsp.so /usr/lib/apache2/modules/mod_fsp.so
Create the file /etc/apache2/mods-available/fsp.load with the following line:
LoadModule fsp_module /usr/lib/apache2/modules/mod_fsp.so
Enable the config files and module:
# a2enconf S10-fsp # a2enconf S60-fazzt-admin # a2enmod fsp
Correct a couple of mistakes in these files:
/etc/apache2/conf-available/S10-fsp.conf -LoadModule fsp_module modules/mod_fsp.so +#LoadModule fsp_module modules/mod_fsp.so
and:
/etc/apache2/conf-available/S60-fazzt-admin.conf - ErrorLog logs/Fazzt-admin-error.log - CustomLog logs/Fazzt-admin-access.log common + ErrorLog Fazzt-admin-error.log + CustomLog Fazzt-admin-access.log common
Don’t forget to install the FAZZT KenCast license provided by KenCast:
# /usr/share/Fazzt/bin/fconf set license PCXXXXXX.kcl
Now you are ready. Start the FAZZT service:
# systemctl start fazzt.service
If everything was right, you must see your service active and without errors. The first start will create the database and its corresponding user and password, and the same for fazzt, which you can verify from the user postgres.
# su - postgres $ psql fazzt psql (11.7 (Debian 11.7-2.pgdg100+1)) Type "help" for help. fazzt=# \dt List of relations Schema | Name | Type | Owner --------+----------------------------------+-------+------- public | applicationinstances | table | fazzt public | applicationschedules | table | fazzt public | applicationservices | table | fazzt public | applicationservicetypes | table | fazzt public | applicationtypes | table | fazzt public | channels | table | fazzt public | channeltypes | table | fazzt public | defaultschedule | table | fazzt public | fazzttbls | table | fazzt public | forwardingconditionactiondefault | table | fazzt public | forwardingconditionactionrules | table | fazzt public | forwardingrules | table | fazzt public | globalattributes | table | fazzt public | notes | table | fazzt public | receivedfiles | table | fazzt public | schedule | table | fazzt public | selectivereception | table | fazzt public | selectivereceptiongroups | table | fazzt public | streams | table | fazzt public | transmissions | table | fazzt (20 rows) fazzt=#
If you don’t see those tables, something went wrong. Perhaps you just have to comment the line 382 of the startup file /usr/share/Fazzt/bin/fazzt-setup since createlang is no more supported nor necessary in current Postgres. Try again.
It is important to note that Debian uses nftables instead of iptables to configure a firewall and you will have to open the port 4039 and accept everything from the interface you use to connect the decoder. In my case, I had to add these lines to /etc/nftables.conf and restart the nftables service.
iifname eno4 accept tcp dport 4039 accept
Now restart Apache.
# systemctl restart apache2
PART III: KENCAST FAZZT CONFIGURATION
Let’s configure the FAZZT Client for the GNC-A ingestion. At the menu on the left, choose “Configuration” -> “Channels” and then, at the “Channels” window, choose “Channels Defaults”. At “Interface”, choose the IP address of the Network Card where you have your DVB-S receiver connected. Click on “Save”.
– Select the ingestion folder at “Configurations” – “Storage Settings” – “Virtual Paths: View/Edit”
– Click at the backslash “\” as shown on the image below and choose the folder where the received files will be stored. In this procedure we suggested “/data/fazzt” but it may be any folder you want.
– Back to the “Channels” interface, click at the “1.Main” channel:
– And at “Interface”, choose “default”:
– After a while (a couple of minutes), you should see the GNC-A Broadcast channels being listed at the “Configuration” – “Channels” interface.
Congreatulations! Your GNC-A station is ingesting!
