How to create your own Radio Station using a dynamic ip domain.

Dimitris Tzemos — Thu, 02 Apr 2026 23:20:16 +0000

In previous posts “Steps to configure Dehydrated for ZeroSSL and Let’s Encrypt” and “Steps to configure Dehydrated for ZeroSSL and Let’s Encrypt for One IP and multiple domains”
We saw how we can create a certificate for our domains.

Now will see step by step how we can create our own radio station using a dynamic domain and the certificates we had created.
I try to be as simple as i can and most work can be done by copy and paste.

First have to create a dynamic domain e.g. on noip.me lets use for this "how to" the foo.ddns.net

we have to open on our router the ports 80 for httpd, 8000 for icecast, 443 for ssl, 8443 secure port for icecast

I have build for salix 64 bit the packages because packages i use for slackel do not run on salix of course.

Download and install icecast package, libigloo and
install rhash

sudo slapt-get -i rhash

Download and install mpd package
Download and install mympd package
Optional install libmpdclient

sudo slapt-get -i libmpdclient

and Download mpc and install it

On slackel we just do this to install the packages

sudo slapt-get -u
sudo slapt-get -i icecast mpd mympd

Replace the /etc/icecast.xml with this

</icecast>

you can change the /live with /whatever_mount_you like

Create the certification key for icecast secure connection.The fullchain.pem and privkey.pem we have created on
previous posts “Steps to configure Dehydrated for ZeroSSL and Let’s Encrypt for One IP and multiple domains”
or “Steps to configure Dehydrated for ZeroSSL and Let’s Encrypt”
for foo.ddns.net, have to be copied in bundle.pem (we use it in icecast.xml above in line /etc/icecast2/bundle.pem)

mkdir -p /etc/icecast2
cat /etc/dehydrated/certs-letsencrypt/foo.ddns.net/fullchain.pem /etc/dehydrated/certs-letsencrypt/foo.ddns.net/privkey.pem > /etc/icecast2/bundle.pem
chown nobody:nogroup /etc/icecast2/*
chmod 600 /etc/icecast2/*

Set up mpd client.
Copy this to /etc/mpd.conf

Set up mympd web UI client for mpd. I have created a script which automatically set up mympd with your radio domain.

sudo RADIO="https://foo.ddns.net" sh /usr/src/mympd/config-helper.sh

Set apache
Edit /etc/httpd/httpd.conf

Create a password for user admin so only admin (you) can log in to mympd web UI

sudo htpasswd -c /etc/httpd/.htpasswd admin

Start httpd (apache)

sudo killall httpd
sudo service start httpd

check if httpd is running

ps ax |grep httpd

Start icecast


sudo service start icecast

start mpd

sudo service start mpd

start mympd

sudo service start mympd

check if icecast is running

ps ax |grep icecast

1610 ?        Sl     0:23 /usr/bin/icecast -c /etc/icecast.xml -b

we see icecast is running using /etc/icecast.xml config

check if mpd, mympd are running

ps ax |grep mpd

 1714 ?        Ssl   14:40 /usr/bin/mpd /etc/mpd.conf
 1791 ?        S      0:00 su -s /bin/sh -c /usr/bin/mympd -w /var/lib/mympd -a /var/lib/mympd/cache mympd
 1793 ?        Ssl    0:00 /usr/bin/mympd -w /var/lib/mympd -a /var/lib/mympd/cache

we see mpd is running using /etc/mpd.conf config file and mympd is running also as user mympd which created from config-helper.sh script above.

check in which ports icecast, mpd, mympd are listening (I got these from my icecast, mpd, mympd used for my radio station to show the output of commands)

sudo netstat -anpt | grep  'icecast'
we see icecast is listening on 8000, 8443 from outside 127.0.0.1:8000 is our inside port

192.168.1.210:8443 is my local ip to secure port 8443 and 85.75.211.110 is my dynamic ip i get from my host provider this is the ip of my meraklis.ddns.net domain so when user type on firefox https://meraklis.ddns.net as we see bellow they are listening to my “Meraklis Radio”
or typing https://meraklis.ddns.net:8443/live on vlc or smplayer or exaile they llisten to “My Radio” station. Same for http://meraklis.ddns.net:8000/live unsecured connection used by https://dir.xiph.org/ radios directory

sudo netstat -anpt |grep mpd

we see that mpd is listening in its default port 6600. And port 8000 send to icecast media server the streaming to go outside to internet

we see mympd is listening to internal port 8081 we do not need this port to be opened

If you have created your playlists then typing on Firefox
https://foo.ddns.net/mympd
you will see mympd interface from where can add playlists or songs to play in random or single mode etc

Your stream url is https://foo.ddns.net:8443/live or insecure http://foo.ddns.net:8000
https://foo.ddns.net:8443 goes to icecast web interface where can log in as administrator using username:admin and pass:hackme
typing https://foo.ddns.net/mympd on you mobile phone can control your radio from where you are.
also for listen from you phone type https://foo.ddns.net:8443/live
or for icecast web type https://foo.ddns.net:8443 or http://foo.ddns.net:8000
These https://foo.ddns.net:8443/live or http://foo.ddns.net:8000/live can be used on vlc or smplayer or exaile to listen to your radio from outside on internet.

To have users to listen to your radio without to type https://foo.ddns.net:8443/live just https://foo.ddns.net
copy these to /var/www/htdocs/index.html

To see the “My Radio” running on my laptop, i have changed the foo.ddns.net to meraklis.ddns.net and also i discovered that running two instances of icecast, mpd and mympd with different configurations can have two stations to stream different songs under the same dynamic ip.
Furthermore can create some php pages and a mysql database where listeners can send you radio orders to play. If anyone is interesting can tell me to send or post here the php files and details. You can see the admin_radio_orders page in the admin_orders-img2.png admin_orders-img3.png on the screenshots link bellow.

The two radio stations My Radio created for this post and Meraklis Radio are running on my lenovo laptop 8GB RAM and from a 64GB USB stick where slackel is installed (real installation), two years ago, which upgraded to latest updates almost every day because of slackware current tree.

Slackel 7.7 MATE

Dimitris Tzemos — Tue, 27 Feb 2024 20:03:10 +0000

Slackel 7.7 MATE has been released.
Includes the Linux kernel 6.6.11, MATE 1.26.2 and latest updates from Slackware's 'Current' tree. Also includes salixtools borrowed from Salix.

This release is available for both 32-bit and 64-bit systems. The 64-bit iso supports UEFI/EFI systems as well.

The 64-bit iso image support booting on UEFI systems.
Iso images are isohybrid.
Iso images can be used as installation media.

This release includes mozilla-firefox 121.0.1, mozilla-thunderbird 115.6.1, libreoffice 7.6.2, gimp 2.10.36, smtube 21.10.0, smplayer 23.12.0, mpv 0.34.1, MPlayer-20221009, exaile 4.1.1, brasero 3.12.2, isomaster 1.3.13, pidgin 2.14.12, transmission 2.94 and many more. It includes the flatpak so the user has access to dozens of apps to install.

Gui tools developed in house also included:

instonusb to create a live slackel usb stick with persistent encryption file.
multibootusb to create a live usb including 32 and 64 bit live editions of slackel.
Slackel Live Installer (SLI) to install slackel to internal or external USB SSD or USB stick.
install-upgrade-kernel-ext-usb-gtk gui tool to install or upgrade kernel for real installations on external usb stick or ssd disk.
install-upgrade-kernel-gtk gui tool to install or upgrade kernel for real installations on internal hd or ssd or nvme disk.

You can also use the script install_on_usb.sh existed in iso in boot folder to create the usb in any distribution. Read the respective instructions in this file: README_INSTALL_ON_USB.TXT
Windows users can use the rufus application which exists in the iso image in boot folder to transfer the iso to a USB stick under windows system. Be sure to name the usb label "LIVE" without quotes.

Slackel Live Installer (SLI) can do a real installation to an external usb stick or usb ssd or usb hard disk, creating the necessary initrd for booting. For this, just create a msdos partition table on /dev/sdb or /dev/sdc and a linux ext4 partition on /dev/sdb1 or on /dev/sdc1 where /dev/sdb is your first usb device, /dev/sdc the second usb plug in device. Sign the /dev/sdb1 or /dev/sdc1 bootable. (Note that if you have an nvme internal disk as in modern laptops then your first usb device will be /dev/sda1, the second /dev/sdb)
Create also a linux swap partition to /dev/sdb2 or /dev/sdc2, with size 4 GB according the memory you have.
Do not create a EFI partition.
If you boot using a slackel live mate dvd then your external usb device will be recognized as /dev/sdb.
If you boot using a slackel live mate usb then the second usb you will use for real installation it will be recognized as /dev/sdc. (or /dev/sdb if you have an nvme internal disk e.g. modern laptops)

Of cource can create a gpt partition table, a fat32 partition (for EFI) on /dev/sdb1 which have to be signed esb,boot, an ext4 linux partition on /dev/sdb2 and a swap partition /dev/sdb3. This is the same installation as on internal ssd disk.

In details:
Steps needed:

boot with live iso or live usb. After we see live environment, plug in the usb stick or external ssd or hd disk where we like to install slackel.
this external device will recognized as /dev/sdb or /dev/sdc as i mention above. Or /dev/sda if you have an nvme internal disk.
run sli
press gparted button and pick up sdb or sdc. Unmount any partitions if are mounted or usb had a previous installation. Then delete all partitions on this device.
create a msdos partition table on this device (/dev/sdb or /dev/sdc) or /dev/sda1 if you have an nvme internal disk.
create an ext4 partition where we will install the linux system and a 2 or 4 GB swap partition according the memory you have. Check the linux partition /dev/sdb1 or /dev/sdc1 bootable
close the gparted and will return to sli. You will see on Install location "dev/sdb1" or "/dev/sdc1" or "/dev/sda1" if you have an nvme internal disk.
check grub as bootloader.
Set root password, user name and user password.
choose full installation which is the default and click on "install live system"

after installation finishes close sli.

shutdown, unplug both usb's and plug in only the one where you installed the system.
Power on.
Then press fn+F12 (in my case for lenovo laptop) and from bios boot menu choose the usb to boot.
To upgrade the kernel in the future, type in a mate-terminal
sudo install-upgrade-kernel upgrade huge (This upgrades the kernel and also run update-grub. For internal or external installation)
sudo make_initrd_update_grub (This needed only if we have installed on an external usb device, otherwise system will not boot. Do not use it if have installed on an internal hard disk or ssd e.g. /dev/sda)
OR use from menus the install-upgrade-kernel-ext-usb-gtk gui tool to install or upgrade kernel for real installations on external usb stick or ssd disk.
and install-upgrade-kernel-gtk gui tool to install or upgrade kernel for real installations on internal hd or ssd or nvme disk.

I hope that fans of mate will find it useful.

It is good to read the Slackel Startup Guide before install Slackel MATE.

To browse samba shares with caja type in a mate-terminal caja smb://ip-address/sharename (e.g. caja smb://192.168.1.8/tmp)

(The root password for the live CD is “live”. Standard user login is “one” with password: "one") (no quotation marks).
For installation and for all work required administration privileges the super user "one" with password "one" is used.

Minimum system requirements: Mate is much heavier than openbox

Minimum Core 2 Duo or Recommended Core i3
3GB (RAM) or 4GB (RAM) for libreoffice, firefox and other heavy applications.
20 GB HDD

Slackel 7.7 MATE maintains its user-friendly approach, combining the latest updates, convenient GUI tools, and enhanced compatibility. Whether you’re a seasoned user or new to Slackel, this release promises an enriched Linux experience.

How to Greek polytonic on openbox

Dimitris Tzemos — Sun, 11 Aug 2019 09:49:02 +0000

There are not only Greek users but other users as well who want to write greek polytonic e.g. in universities. This might be helpful for anyone interesting.

Writing greek polytonic, monotonic and ancient, modern spell checking on LibreOffice and Openbox.
In slackel all these are set up in the live iso and after installing the system on hard disk or usb stick. So for slackel users there is no need to follow these steps.

==set the key==
Open with geany the file ~/.config/openbox/rc.xml
e.g. geany ~/.config/openbox/rc.xml

go to line 342 (or find the last row with /keybind and add the lines bellow)

          <keybind key="C-1">
           <action name="Execute">
            <command>sh ~/.polytonic</command>
             <startupnotify>
              <enabled>yes</enabled>
              <name>Polytonic/Monotonic</name>
             </startupnotify>
            </action>
           </keybind>

Save the file

==Create the polytonic file==
Create the file ~/.polytonic

geany ~/.polytonic and paste the lines

#!/bin/sh
# Dimitris Tzemos dijemos@gmail.com
# Αρχείο για αλλαγή μονοτονικού πολυτονικού πληκτρολογίου

if [ -z "$check" ];then
setxkbmap us,el -variant ,extended

else
setxkbmap us,el -variant ,polytonic
zenity --info --timeout 1 --text 'Πολυτονικό πληκτρολόγιο ενεργό' 1
fi
if [ -r /etc/X11/Xmodmap ];then xmodmap /etc/X11/Xmodmap;fi
if [ -r "$HOME"/.Xmodmap ];then xmodmap "$HOME"/.Xmodmap;fi

Save the file

==Messages ==
Μονοτονικό πληκτρολόγιο ενεργό = Monotonic keyboard active

Πολυτονικό πληκτρολόγιο ενεργό = Polytonic keyboard active
you can change greek messages with english ones above if you like.

Now every time you press Ctrl+1 change between monotonic to polytonic and polytonic to monotonic

==Libreoffice==
For greek spelling modern and/or ancient greek download these files and install them from libreoffice tools-> extensions

modern greek
http://sourceforge.net/projects/aoo-extensions/files/1411/2/el_gr_v110.oxt/download

ancient greek
http://sourceforge.net/projects/aoo-extensions/files/2313/1/grc.oxt/download

Thats it!!!
Now can write greek modern or polytonic in libreoffice and also have spell checking.

To write greek polytonic press alt-shift to change keyboard and then press ctrl+1 to go to polytonic.

== ancient Greek polytonic from Homer Iliad
Μῆνιν ἄειδε θεὰ Πηληϊάδεω Ἀχιλῆος
οὐλομένην, ἣ μυρί᾿ Ἀχαιοῖς ἄλγε᾿ ἔθηκε,
πολλὰς δ᾿ ἰφθίμους ψυχὰς Ἄϊδι προΐαψεν
ἡρώων, αὐτοὺς δὲ ἑλώρια τεῦχε κύνεσσιν
οἰωνοῖσί τε πᾶσι· Διὸς δ᾿ ἐτελείετο βουλή,
ἐξ οὗ δὴ τὰ πρῶτα διαστήτην ἐρίσαντε
Ἀτρεΐδης τε ἄναξ ἀνδρῶν καὶ δῖος Ἀχιλλεύς.

== above text in modern Greek monotonic (translation)
Ψάλλε θεά, τον τρομερό θυμόν του Αχιλλέως
Πώς έγινε στους Αχαιούς αρχή πολλών δακρύων.
Που ανδράγαθες ροβόλησε πολλές ψυχές στον Άδη
ηρώων, κι έδωκεν αυτούς αρπάγματα των σκύλων
και των ορνέων – και η βουλή γενόταν του Κρονίδη,
απ’ ότ’, εφιλονίκησαν κι εχωρισθήκαν πρώτα
ο Ατρείδης, άρχος των ανδρών, και ο θείος Αχιλλέας.

== Translation in English
Sing, O goddess, the anger of Achilles son of Peleus,
that brought countless ills upon the Achaeans.
Many a brave soul did it send hurrying down to Hades,
and many a hero did it yield a prey to dogs and vultures,
for so were the counsels of Jove fulfilled from the day
on which the son of Atreus, king of men, and great Achilles,
first fell out with one another.

How to set up murmur server/mumble client

Dimitris Tzemos — Sun, 11 Aug 2019 08:39:56 +0000

This "Mumble & Murmur" voice chat application guide shows how to setup the murmur server on Slackel, Salix so a group of users can use
mumble client to voice chat each other. Software used in this guide consists of:

murmur (the server application)
mumble (a voice chat application for groups)

== What is Mumble? ==
Mumble is a voice chat application for groups. While it can be used for any kind of activity, it is primarily intended for gaming.
It can be compared to programs like Ventrilo or TeamSpeak. People tend to simplify things, so when they talk about Mumble they either talk about "Mumble"
the client application or about "Mumble & Murmur" the whole voice chat application suite.

== What is Murmur? ==
"Murmur" is the name of the server application. In any case, if anyone talks about Murmur it is for sure the server part.

== Obtain a dyndns domain ==

Obtain a DNS domain and create one with a dynamic dns provider (e.g. noip.com)
Port forward tcp, udp port 64738 using your router interface

After that, we are ready to go on.

== Getting and Installing Murmur and Mumble ==

Install murmur and mumble with the usual commands:

   slapt-get -u
   slapt-get -i murmur
   slapt-get -i mumble

== Set Up murmur Server ==

To make things easier for you just run the script on /usr/doc/murmur-1.2.19/config-helper.sh to create mumble-server group and mumble-server user:

   sudo sh /usr/doc/murmur-1.2.19/config-helper.sh

The above script will also create:

/var/log/mumble-server
/var/lib/mumble-server
/var/run/mumble-server and chown these by mumble-server group, mumble-server user

Next open as root /etc/murmur.ini

Change the following variables
database= to database=/var/lib/mumble-server/mumble-server.sqlite
#logfile=murmur.log to logfile=/var/log/mumble-server/mumble-server.log
#pidfile= to pidfile=/var/run/mumble-server/mumble-server.pid
The above variables are set up during installation, we just mention them here for users to know about them.
#welcometext=Welcome to this server running Murmur. Enjoy your stay! to welcometext="whatever you like!"
It is important to set up this because it is the name your server will appear in public lists under your country flag
#registerPassword=secret to registerPassword=secret
#registerUrl=http://mumble.sourceforge.net/ to registerUrl="your_dns_domain" (e.g. registerUrl=http://myserver.noip.me)

It is important to set up this otherwise no one can finds you.
It is your ip. Also put this in your router to be updated each time your ip changes.

#uname= to uname=mumble-server

this variable has also set up during installation
Save the file /etc/murmur.ini
and start murmur server as root

      sudo chmod 755 /etc/rc.d/rc.murmur 
      sudo /etc/rc.d/rc.murmur  start

Even you start murmur server as root it will switch to mumble-server user ( Look above uname=mumble-server)

After some minutes your murmur server will appear in "Public Internet" under your country flag with the name you have in registerName= variable

===Setting SuperUser Password===

Now you will need to set the SuperUser Password. The server should be running at this point.
Open a terminal and write as root

      sudo murmurd -ini /etc/murmur.ini -supw  your-password

We will need this to set up rooms, register users, kick users etc

== Set Up mumble client ==

As user run mumble client. It is in Internet group of programs in menus.

When mumble appears click on server --> connect

A window appears. You will see your server name under LAN.

Right click on your server name and click "add to Favorite".
Under "Favorite", Right click on your server name and click on "Edit"
Delete the line next to "Address" and write there what there is in registerUrl "without http://" (e.g. myserver.noip.me)
Next to "Port" write 64738
Next to "Username" write whatever nick you like
Click on "OK"
Click on "Connect"
In the next warning message, accept the certificate. Click on "Yes"

Congratulations
You have just connected to your murmur server.

=== Connecting as SuperUser===

click on server -> connect
Under "Favorite", Right click on your server name and click on "Edit"
Delete the user name and write there SuperUser ( as i wrote it)
Write the SuperUser password
Click on "OK"
Click on "Connect"

You are SuperUser. But SuperUser has no voice. So give to your previous user all SuperUser capabilities plus voice ability.

=== Connecting as previous user ===

click on server -> connect
Under Favorite, Right click on your server name and click on "Edit"
Delete the Password
Delete the SuperUser name and write there the previous user name
Click on "OK"
Click on "Connect"

== Make Your Server Public==

===create a Certificate Authority (CA)===

You do not have to do the following anymore. Server will registered as Public using murmur certificate. You can do these if you want to use your own certificate Authority.

create a working directory
```
   mkdir CAwork
    cd CAwork
```
first set yourself up as a CA. a CA can sign a certificate requests to create an SSL certificate.
Run the command (a directory demoCA will be created under CAwork)
```
     /etc/ssl/misc/CA.pl -newca
```
hit enter to create CA certificate
enter the PEM pass phrase
renter the pass phrase

fill out the info asked for. Be sure to set all fields (for example )

     countryName  = GR
      stateOrProvinceName    = Some-State
      organizationName       = Internet Widgits Pty Ltd
      commonName             = ariadni.noip.me CA
      emailAddress           = webmaster@ariadni.noip.me

Make sure the commonName to be different from the commonName in the next step.

CA.pl will create a cacert.pem in the directory demoCA, the private CA key is in private/cakey.pem

===Create a Certificate Request===
next we will create a request for a server certificate.

          /etc/ssl/misc/CA.pl   -newreq-nodes

some servers need a private certificate not protected by a pass phrase. the -nodes (note: no space between -newreq and -nodes) tells openssl to make an unpassword protected certificate.
Be sure to set the Common Name to the dns name of the server that will be using it!

Be sure to set all fields (for example )

            countryName  = GR
            stateOrProvinceName  = Some-State
            organizationName     = Internet Widgits Pty Ltd
            commonName           = ariadni.noip.me
            emailAddress         = webmaster@ariadni.noip.me

Make sure the commonName to be different from the commonName in the above step. e.g I have set the names ariadni.noip.me CA and ariadni.noip.me

the request file will be created in the directory you're currently in with a name of newreq.pem and the private key is in newkey.pem

===Sign the request===

next use your CA certificate to sign the certificate request:

           /etc/ssl/misc/CA.pl   -sign

you'll be prompted for your CA password. the info from the newreq.pem file will be displayed and you'll be asked if you want to sign it. After the certificate is signed, and you're prompted if you want to commit the certificate.

The certificate is created, signed and stored in newcert.pem, in the same directory you're currently in.

Now some more job and we are ready.
The certificate has both the encoded version and a human-readable version in the same file. You can strip off the human-readable portion as follows:

          cp demoCA/cacert.pem tmp.pem
          openssl x509 -in tmp.pem -out cert.pem

cert.pem is our Root certificate

          mv newcert.pem tmp.pem
          openssl x509 -in tmp.pem -out newcert.pem

newcert.pem is our signed requested file from our Certificate Authority

===Installing the Certificate and Key===
Create a file mycert.pem with contents of both Root Certificate Authority certificate (cert.pem) and signed certificate file (newcert.pem)

          cat cert.pem newcert.pem > mycert.pem
          mv newkey.pem mykey.pem

After this step, you have two files:

A private key in mykey.pem
A combined Root Certificate Authority certificate and your signed certificate in mycert.pem

Now the file mycert.pem contains the certificate and mykey.pem contains the key.

copy these two files to /etc/ where murmur.ini exists (you can copy them elsewhere but you have to put the path in murmur.ini)
Edit /etc/murmur.ini uncomment and change the following two lines:
```
         sslCert=mycert.pem
         sslKey=mykey.pem
```

===Restart murmur===

             /etc/rc.d/rc.murmur restart

Tell your friends about your murmur server and that they can found you under your country flag in Public Internet server list of mumble.
In any case, give them your dyndns.org domain name to add it to "Favorite" (see above).
And can connect and talk with you even your server do not appear in Public Internet server list of mumble.

How to configure my own dns server with my static ip

Dimitris Tzemos — Sun, 11 Aug 2019 08:04:06 +0000

Because a friend had to setup his own dns server using the static ip and installed the ubuntu on the server,
so I set up the dns server.
The instructions below are for any possible need to do the same.
The domain here is my-domain.gr you replace it with your own.

The following regulations apply to Ubuntu, in slackware, slackel, salix do the same in their respective files.
The instructions are simple and not in the correct technical vocabulary to be understand from all.
The following instructions work and of course someone else may use different settings.

It is assumed that on the registrar, we maintain our domain name, we have created a nameserver e.g. ns0.my-domain.gr giving it a static ip x1.x2.x3.x4
We can define a second with the same static ip ns1.my-domain.gr
Then in the domain name that we enshrine in the example my-domain.gr put as Domain Name Servers (nameservers) the ns0.my-domain.gr and ns1.my-domain.gr

And also a few hours to 48 hours may need for the nameservers to be updated with the ip corresponding to our ns0.my-domain.gr.
So if you change the nameservers of your domain, the transition to the new hosting server will be completed in about 3 to 48 hours, depending on the company that provides you connect the Internet.
So making a dig from any pc you will not find the domain if you do not first the nameservers around the world updated.

The following we do in our own server if you run from home and have static ip or do after login to the server we have in such a company, using ssh.
Here as an example we use the domain my-domain.gr. You put your own which you have first-register.
The static ip is x1.x2.x3.x4.
x1.x2.x3.x4 replace it with your static ip
The ip of the company's nameservers are k1.k2.k3.k4 m1.m2.m3.m4

Below where is x1, x2, x3, x4, k1, k2, k3, k4, m1, m2, m3, m4 will put the corresponding numbers.

How to setup a streaming multimedia server (internet radio station)

Dimitris Tzemos — Sat, 10 Aug 2019 20:15:32 +0000

This is for slackel linux.
Same settings can be used in any linux distribution. You have to install icecast, mpd and gmpc (optional) in your linux distribution.

what is Icecast

Icecast is free server software for streaming multimedia. Icecast, is a program that streams audio data to listeners.

what is mpd

mpd is a music player daemon - a daemon for playing music

what is gmpc

Gnome Music Player Client (gmpc) is a gui front-end for mpd

Let begin:

Obtain a dns domain

"Obtain a DNS domain" and create one with a dynamic dns provider (e.g. https://www.noip.com )
Port forward tcp, udp port 8000 using your router interface
i hope you know how to do this. e.g. if your laptop has internal ip 192.168.2.4 for example you have to set router port forwarding 192.168.2.4 to 8000 port so users can reach you from outside to 192.168.2.4 internal ip

Getting and Installing icecast mpd and its gui front-end gmpc
```
 sudo slapt-get -u
 sudo slapt-get -i icecast mpd gmpc
```
Setting up icecast config file

Open file /etc/icecast.xml and change some settings:

<source-password>hackme</source-password> to whatever you like
<relay-password>hackme</relay-password> to whatever you like
<admin-user>admin</admin-user> to whatever you like
<admin-password>hackme</admin-password> to whatever you like
<shoutcast-mount>/live</shoutcast-mount> to whatever you like, if it is not set then default /stream will be used e.g. set it to live

<hostname>localhost</hostname> to your dynamic domain name e.g. mediaserver.noip.me

 <!-- add this if you want your station listing on icecast directory, so people all over the world can find you -->
 <directory>
    <yp-url-timeout>15</yp-url-timeout>
    <yp-url>http://dir.xiph.org/cgi-bin/yp-cgi</yp-url>
    <public>1</public>
 </directory>
 <security>
  <chroot>0</chroot>
   <changeowner>
     <user>nobody</user>
     <group>nogroup</group>
   </changeowner>
  </security>

Save file /etc/icecast.xml

prepare your mp3 files directory

put your mp3 files under a directory e.g. ~/Desktop/mp3

create your .mpdconf
run
```
 mpd-initial.sh
```

a file ~/.mpdconf will be created in your home directory

Edit this file and change it as follows

music_directory     "~/Desktop/mp3"
playlist_directory      "~/.mpd/playlists"
log_file            "~/.mpd/log"
pid_file            "~/.mpd/pid"
state_file          "~/.mpd/state"
bind_to_address "localhost"
port                "6600"
input {
    plugin "curl"
 }
audio_output {
type        "shout"
encoding    "mp3"           # optional
name        "Ariadni Greek Radio"
host        "localhost"
port        "8000"
mount       "/live" # same as above in icecast.xml
password    "hackme" # password_same_as icecast_server_password_above"
bitrate     "128"
format      "44100:16:2"
description "Watever you like e.g Rock" # optional
url  "http://mediaserver.noip.me"   # optional but same as above in icecast.xml
genre   "your genre e.g. Greek"     # optional
public  "yes"     # optional
mixer_type    "software"  # optional
}
# Need this so that mpd still works if icecast is not running
audio_output {
type "alsa"
name "fake out"
driver "null"
mixer_type      "software"
}
# Character Encoding
# If file or directory names do not display correctly for your locale then you 
# may need to modify this setting.
#
filesystem_charset "UTF-8"
#
# This setting controls the encoding that ID3v1 tags should be converted from.
#
id3v1_encoding  "ISO-8859-1"
#

create a playlist

find ~/Desktop/mp3/*.mp3 > ~/.mpd/playlists/myplaylist.m3u

run icecast and mpd

sudo icecast -c /etc/icecast.xml -b
mpd ~/.mpdconf

run gmpc from menus and stop or play the songs you like.
check "Repeat mode" and "Random mode" under Control menu

tip:
can create a file ~/icecast.sh including the lines

    sudo icecast -c /etc/icecast.xml -b
    mpd ~/.mpdconf

and run it to not have to type again every time want to run your media server. Just type

    sh ~/icecast.sh

You and your listeners can listen to your internet radio by typing in a browser or vlc or clementine or smplayer the url
http://mediaserver.noip.me:8000/live

In slackel.gr site the ariadni radio http://ariadni.noip.me:8000/live has been set up as above and streaming from my laptop.

Playing youtube videos on smplayer through smtube using the mpv player

Dimitris Tzemos — Sat, 10 Aug 2019 14:15:54 +0000

Playing youtube videos on smplayer through smtube using the mpv player

I have tried vlc, mplayer, smplayer tried to play youtube videos in ubuntu, slackel and other distributions as well.
But upon moving the time slider to a new location within the video Smplayer crashes. Log file message reads...

MPlayer interrupted by signal 11 in module: seek
ID_SIGNAL=11

I found that smtube and smplayer using mpv media player can play youtube videos without crashed.

In slackel 7.2 can install smplayer, mpv and latest smtube plus libass which is a dependency.

    sudo slapt-get -u
    sudo slapt-get -i smplayer libass mpv smtube

then run smplayer and check from options in menus that mpv player is default player.

cron and crontab: some classics are timeless

Dimitris Tzemos — Sat, 10 Aug 2019 13:52:44 +0000

cron and crontab: some classics are timeless

Quite often we, as computer users, need to schedule applications or jobs to take place at a given time. Backups typically happen at night, virus scans might happen after dinner, system updates might take place first thing in the morning. It's often useful to have routine tasks performed automatically and at a time when we're not sitting in front of the machine. This week we're going to cover the cron daemon and demonstrate how it can be used to quickly set up periodic tasks.

What does cron do? Well, once a minute the cron daemon checks the file /etc/crontab to see if any tasks are scheduled and, if it finds an applicable task, it runs a given program. The /etc/crontab file is a text file which we can open and examine in any text editor. Let's break down the information fields we will find in that file.

Typically a crontab file will contain two or more lines setting variables. Usually we will see a line setting the path to a shell and another listing the paths where cron can find executable files. These may look like the following:

   SHELL=/bin/sh
   PATH=/sbin:/bin:/usr/sbin:/usr/bin

Following these variables we will find lines specifying times and tasks to be run at those times. Let's look at an example of one of these scheduled tasks:

    15 * * * * root logrotate

The first five fields of the line are made up of numbers or stars. These fields represent a given point (or points) in time to let us know when the task will be run. From left to right the fields indicate the minute, hour, day of the month, month and day of the week when a task is to be run. Stars effectively mean "any" or "every". The sixth column indicates which user account will be used to run the task and the final field is the command to be run. In the above example we will run the logrotate command as the root user. This will happen 15 minutes into every hour of every day of every month, on every day of the week. In the following example we will run a backup script as the root user at noon on every Sunday:

   0 12 * * * 0 root my-backup-script

As you can see, we've set the minute field to zero, the hour to twelve (noon) and the day of the week to zero (Sunday). Cron associates Sunday with zero, Monday with one... through to Saturday which is six. Here is another example where we perform a clean-up of the /tmp directory at 6:30pm every evening from Monday through Friday. The dash character allows us to specify a range:

  30 18 * * 1-5 root rm -rf /tmp/*

On most Linux systems it's not just the root user who can schedule tasks, regular user accounts can create their own cron jobs. These user-scheduled tasks are kept separate from the /etc/crontab jobs and can be accessed by running the command:

    crontab -e

The crontab command will open a text editor and allow us to create tasks specific to our account. The main difference between the user-specific schedules and the /etc/crontab file is that the user-specific schedules do not include a username. For example, the following entry in my crontab file will perform a backup of my Documents directory at 5:00am on the first day of each month:

    0 5 1 * * tar czf ~/mybackup.tar.gz ~/Documents

Should we wish to see all of the jobs we have scheduled in our cron file we can run

   crontab -l

to get a complete list. Lastly, we can remove all of our user's scheduled tasks by running:

   crontab -r

The cron program is a very flexible and powerful tool which can be used to automate processes and is particularly good for scheduling backups and system clean-ups. It's a very handy utility to know.

Slackel Hellenic Linux Distribution

Dimitris Tzemos — Sat, 10 Aug 2019 13:39:56 +0000

Slackel 1.0 version was released on 2005 and it was a KDE edition. It was based on slackware 10.2 stable. It was reconfigured with greek language and applications i needed. Then i created a live iso with linux-live scripts 5.1.8 from slax. So i could install it without having to configure it again from the beginning.
