Install Zabbix Proxy configure and connect to Zabbix server on CentOS Linux

1. Why use Zabbix-Proxy hidden advantages of using Zabbix-Proxy ?

Proxy can be used for many purposes and can provide many hidden benefits, just to name few of them:

  • Offload Zabbix Server when monitoring thousands of devices
  • Monitor remote locations
  • Monitor locations having unreliable communications
  • Simplify maintenance of distributed monitoring
  • Improved Security (Zabbix server can be restricted to be connectable only by the set of connected Zabbix Proxy / Proxies



A Zabbix proxy is the ideal solution if you have numerous hosts with multiple slow items that are affecting the performance of the server simply because processes are spending most of the time simply waiting for a response. A proxy can collect information from all hosts using its internal processes and then send raw historical data to the server. The time needed to connect and receive the host response will be on the proxy site, and the server performance will not be affected at all. A proxy just sends raw values to the server, and the server itself does not have to connect to the host to get the data.

2. Install zabbix-proxy-sqlite3 rpm package from Zabbix Official Repositories download page

Zabbix repository provides choice of 3 packages named as follows:


where the last value of the name (after zabbix-proxy) represents database type of the package — MySQL, PostgreSQL and SQLite respectively.

To not bother installing MySQL / PostgreSQL separate database servers, a lightweight choice is to use the sqlite3 db version. 
As I prefer zabbix-proxy data to be stored inside a flat database, thus I choose to use zabbix-proxy-sqlite3.

[root@sysadminshelp:/root ]# yum info zabbix-proxy-sqlite3-5.0.31-1.el7.x86_64

My experience to try to install thethe default CentOS RPM package for zabbix-proxy-sqlite3 provided by default
RPM package that came with CentOS did not work as expected and trying to install / configure and use it via

[root@sysadminshelp:/root ]# yum install zabbix-proxy-sqlite3.x86_64 -y

[root@sysadminshelp:/root ]# vi /etc/zabbix/zabbix_proxy.conf

Led me to a nasty errors seen in /var/log/zabbixsrv/zabbix_proxy.log like:

May 1st 2023, 08:42:45.020 zabbix_server cannot set list of PSK ciphersuites: file ssl_lib.c line 1314: error:1410D0B9:SSL routines:SSL_CTX_set_cipher_list:no cipher match

After some googling and reading some threads came upon this one, there is exmplaed errors preventing the configured zabbix-proxy
to start are caused by the zabbix-proxy-sqlite3 package provided by Redhat (due to openssl incompitability bug or something ).

As one of people in the discussion pointed out the quickest workaround suggested is simply to use the official Zabbix Repository packages for zabbix-proxy-sqlite3, in order to not waste anymore time on this
trivial stuff to install it, simply run:

[root@sysadminshelp:/root ]# rpm -Uvh \

Alternative way if you seem to not have the machine connected to the internet is simply download the package with wget / lynx / curl / w3m from another machine 
that can reach the Internet upload the package via the local LAN or VPN and install it:

# wget

[root@sysadminshelp:/root ]# rpm -ivh zabbix-proxy-sqlite3-5.0.31-1.el7.x86_64.rpm

NOTE ! Before you install proxy, keep in mind that your proxy version must match the Zabbix server version !

3. Generate a PSK random secret key and set proper permissions for zabbix-proxy directories

[root@sysadminshelp:/root ]# cd /etc/zabbix/
[root@sysadminshelp:/root ]# openssl rand -hex 32 >> /etc/zabbix/zabbix_proxy.psk     
[root@sysadminshelp:/root ]# chown root:zabbix zabbix_proxy.psk [root@sysadminshelp:/root ]# vi /etc/zabbix/zabbix_proxy.conf [root@sysadminshelp:/root ]# mkdir -p /var/lib/zabbix-proxy/sqlite3db
[root@sysadminshelp:/root ]# chown -R zabbix:zabbix /var/lib/zabbix-proxy
[root@sysadminshelp:/var/lib/zabbixsrv/sqlite3db]# sqlite3 zabbix_proxy
SQLite version 3.7.17 2013-05-20 00:56:22
Enter ".help" for instructions

sqlite> .databases
seq  name             file
—  —————  ———————————————————-
0    main             /var/lib/zabbixsrv/sqlite3db/zabbix_proxy
[root@sysadminshelp:/root ]# vi /etc/zabbix_proxy.conf

4. Configure zabbix proxy to be able to connect to Zabbix Server

[root@sysadminshelp:/root ]#  vi /etc/zabbix/zabbix_proxy.conf     ############ GENERAL PARAMETERS #################
    ######### PROXY SPECIFIC PARAMETERS #############
    ############ ADVANCED PARAMETERS ################
    ####### TLS-RELATED PARAMETERS #######
    TLSPSKIdentity=PSK zabbix-proxy-fqdn-hostname

5. Check and make sure the installed zabbix proxy as well as the zabbix_proxy server zabbix_agentd client and zabbix_server are at the same major version release

a) Check zabbix proxy version

[root@sysadminshelp:/etc/zabbix]# zabbix_proxy -V
zabbix_proxy (Zabbix) 5.0.31

6. Starting the zabbix-proxy for a first time

Before beginning with installation make sure selinux is disabled, as it might cause some issues with Zabbix

[root@sysadminshelp:/etc/zabbix]# sestatus
SELinux status:                 disabled

If you need to have the selinux enabled you will have to allow the zabbix-proxy into selinux as well:

cd /tmp
# grep zabbix_proxy /var/log/audit/audit.log | grep denied | audit2allow -m zabbix_proxy > zabbix_proxy.te
grep zabbix_proxy /var/log/audit/audit.log | grep denied | audit2allow -M zabbix_proxy
semodule -i zabbix_proxy.pp

[root@sysadminshelp:/etc/zabbix]# systemctl start zabbix-proxy

Also lets enable zabbix-proxy to automatically start it on next server reboot / boot.

root@sysadminshelp:/etc/zabbix]# systemctl enable zabbix-proxy

Normally running zabbix-proxy should provide a status messages like:

[root@sysadminshelp:/etc/zabbix]# systemctl status zabbix-proxy

7. Configure zabbix-agentd to use your just new brand new zabbix-proxy

Here is my sample configuration file:

[root@sysadminshelp:/etc/zabbix]# grep -v \# /etc/zabbix/zabbix_agentd.conf | sed '/^$/d'

Note that the ServerActive given "zabbix-proxy" should be resolvable from the host, or even better you might want to put the IP of the Proxy if
you don't have at least a pseudo Hostname already configured inside /etc/hosts or actual DNS 'A' Active record configured inside a properly resolving
DNS server configured on the host via /etc/resolv.conf.

8. Create and Configure new proxy into the Zabbix-server host

Go to the zabbix server web interface URL into menus:


Administration -> Proxies (Proxy) 

Click on ;

Create Proxy button (uppper right corner)

*Proxy name: usually-your-host-pingable-fqdn
Proxy mode: Active
Proxy address:
Description: pcfreak zabbix proxy

Administration -> Proxies -> Encryption

From "Connection to proxy"

Untick "No encryption"


Tick "PSK"


*PSK Identity: PSK proxy
*PSK: Put the key here (copy from /etc/zabbix/zabbix_proxy.psk generated steps earlier with openssl)

[root@sysadminshelp:/etc/zabbix]# cat zabbix_proxy.psk

Press the "Update" Button


and go again to Proxies and check the zabbix-proxy is connected to the server and hosts configured to use the zabbix proxy reporting frequently.

To make sure that the configured new hosts to use the Zabbix Proxy instead of direct connection to Zabbix Server, go to Latest Data and check whether the configured Hostnames to connect to the Zabbix-Proxy continues to sent Data still.

9. Debugging problems with zabix-proxy and zabbix-agentd connectivity to proxy

In case of troubles check out what is going on inside the Zabbix Proxy / Agent and Server log files

If necessery to Debug further and track some strange errors, you might want to increase the DebugLevel to lets say DebugLevel=5

5 – extended debugging (produces even more information)

If checking both zabbix_agentd.log and zabbix_proxy.log cannot give you enough of a hint on what might be the issues you face with your userparameter scripts or missing Monitored data etc. and hopefully you have access to the zabbix-server machine, check out the zabbix server log as well

Wrapping it up

In this article, we have learned how to install and configure a zabbix-proxy server and prepare a PSK encryption secret key for it.
We learned also  how to connect this server to the central zabbix monitoring host machine in Active mode, so both Zabbix proxy and server can communicate in a secure crypted form,
as well as how to set zabbix_agentd clients to connect to the zabbix proxy
which will from itself send its data to the Central Zabbix server host as well as how to Debug and hopefully solve issues with communication between Zabbix client -> Zabbix Proxy -> Zabbix server.

I know this article, does not say anything revolutionary and there is plenty of posts online talking about how to run yourself a zabbix proxy and make in your home or corporate network,
but I thought to write it down as by writting it and reading a bit more on the topic of Zabbix Server / Proxy / Agent, that give myself a better overview on how this technologies work and such an article will give myself an easier step by step guide to follow,
in future when I have to configure Zabbix Environments for personal hobby or professionally for customers.

Tuesday, May 24th, 2011


I have installed TightVNC to a Windows host just a few weeks ago in order to be able to manage remotely a Windows host and forgot to write down the administrator password 🙂 (stoopid!)

I had to explain to a friend remotely how to change the TightVNC admin password and it was a complete nightmare!

Shortly here is the exact menus one who wants to reset the password of a TigthVNC server after forgotten:

Start -> All Programs -> TightVNC
-> TightVNC Server (Service Mode) ->
TightVNC Service - Offline Configuration.

In the configuration dialog to popup there are the Server and Administration tabs through which a new password can be set.

After the password is change either a restart of the TightVNC server is necessery or a restart of the Windows PC.

How to enable VirtualBox Windows XP FullScreen with VboxGuestAdditions.iso on Ubuntu 11.10 Linux

Tuesday, January 17th, 2012

Right after installing Windows XP inside VirtualBox, I've found out everything works fine except the screen. Even though pressing (Right CTRL + F) was changing the Windows XP running window to FullScreen the XP screen was taking only a part of the whole screen area, where almost half of the screen was visible as simply staying blank.

A bit of research and I found the issue is caused by missing VirtualBoxGuestAdditions .

VBoxAdditions is a package which should be installed inside the VirtualBox by navigating to Devices -> Install Guest Additions

Virtualbox offers a download of a VboxGuestAdditions_4.1.2_Ubuntu.iso from url;, anyways this download fails since the URL is currently unavailable.

To fix this two ways are possible:

1. Download VBoxGuestAdditions.iso from here and put it in directory /usr/share/virtualbox , e.g.:

root@ubuntu:~# cd /usr/share/virtualbox
root@ubuntu:/usr/share/virtualbox# wget

2. Download and install virtualbox-guest-additions-iso_4.1.2-1_all.deb

root@ubuntu:~# wget
root@ubuntu:~# dpkg -i virtualbox-guest-additions-iso_4.1.2-1_all.deb

Next to enable and install guest additions once again use menus:

Devices -> Install Guest Additions

VirtualBox Install Guest Additions Ubuntu Screenshot

The screen to appear next will be similar to:

VBox guest Additions windows Ubuntu

Further on follow the few dialogs to complete the installations and integration of Guest Additions and restart the Virtual machine and hooray the Windows will appear in Full screen in VirtualBox ! 😉

12 must have Joomla extension plugins / Essential modules for new Joomla CMS install

Thursday, June 16th, 2011

Joomla bundle of must have extensions picture

These days very often I have to install, plain new Joomla based websites. I’ve realized that since there is no structured guide to follow describing the most essential plugins that every new fresh new joomla installation is required to have.
Thus I took the time and wrote this post, as it will be useful to myself in my future new joomla based websites establishment, I also believe these guide will be useful to other Joomla enthusiasts or administrators in their daily work.

Below I will describe in short the installation, configuration and oddities I’ve faced during installment of the above described bundle of plugins on a plan Joomla 1.5 install.These article will walk through 12 joomla essential plugins that I believe every fresh Joomla installation should be equipped with.
Hope this guide will be helpful to you. Now let’s start it up:

1. JoomlaXplorer – A sophisticated web file explorer for Joomla

One of the basic modules, beneficial with a new joomla CMS install is Joomla Xptplorer . This module enables the joomla admin to browse files in a web file explorer, on the server where the joomla CMS is installed. Below you see how handy the joomla web explorer provided by the plugin is:

4. Akeeba Backup Joomla solution

Akeeba backup Joomla Module

Installing a joomla backup solution is very essential if you does take care about your data, it often happens that server hard disk got crashes or a RAID massives got corrupted or some kind of other unexpected disaster hits the server. In these terrible times, having a website backup will save you nerves and data recovery funds, not to mention that in many cases data recovery is impossible.

Joomla has a very easy to use software for creating full website backup called Akeeba Backup

To start using the software one must:

a. Download Akeeba Backup and install it via:

Extensions -> Install/Uninstall

After the Akeeba Backup installation is over, to create your first backup, one needs to navigate to:

Components -> Akeeba Backup -> Backup Now

Each Akeeba backup (a version of the website’s files data and sql info) will be created in an archive file with the extension .jpa
The backup files are created under joomla’s website (main) root directory in directory location administrator/components/com_akeeba/backup

The Akeeba plugin also has capabilities to recover a (.jpa) backup restore point easily.
To recover a backup with the Akeeba plugin one needs to do it once again, via the plugin joomla web interface.
5. Google Analytics (place easy tracking code) in Joomla

Google Analytics Tracking Module for Joomla

The module is available from Joomla Extensions on

At the current time of writting you need to download the analytics_tracking15,zip file

On the right pane you will notice in the Module Parameters the Analytics_uacct_code field. In the uacct_code field you need to paste your UA obtained from your created google-analytics account.
This code is usually something like UA-2101595-10
Now place your code their and press the save green button located near the right top of the screen. You should see the text in blue Item Saved which would indicate your UA code is stored already in the Google Analytics Tracking Module, now press the Cancel button located again on the right top.

6. Itprism (Facebook, Twitter etc.) Social Network share buttons Joomla plugin

ITPShare Large Social Buttons Joomla

a. to add the itpsocialbuttons to joomla Download the Itpsocialbuttons latest module files from or use my mirrored module files below:

Download mod_itpsocialbuttons .zip file
Download plg_itpsocialbuttons .zip

After having the two files necessery to be installed to make the ITPSocialButtons appear on website, installation is done like with any other installation:

Extensions -> Install/Uninstall -> Upload Package File (Choose File)

Next its necessery to configure the plugin to do so, follow to menus:

Extensions -> Module Manager -> Share

You will notice the Share dialog in the list of Module Name column in Module Manager

Here is a screenshot on how the settings options for ITpsocialbuttons will look like:

Mod ITpSocialButtons settings screen

The options which I personally changed was:

Show Title – I set this one to No as I wanted to omit the plugin title text to appear on my website.
Further on I’ve set the Enabled option to Yes to enable the plugin and choose the buttons Style option to be of a Small buttons type.
I’ve also found that the most suitable position for the Social Share buttons were to be of a right – Position .

Here is how the social network itprism share buttons looks like:

ITprism Joomla Social Share Plugin various button types

The plugin supports sharing of joomla pages to the following list of social networks:

  • Facebook
  • Google Bookmarks
  • StumbleUpon
  • Technorati
  • Twitter
  • LinkedIn

The module configuration, also allows the user to configure the type of social network buttons, one wants to display on the website.

7. Joomla JCE Content Editor

This content editor is really awesome compared to the default editor TinyMCE. If you want to have an options rich content editor for Joomla, then this is the one for you 🙂
download JCE Content Editor here

After installing the JCE Joomla content editor in order to enable it as a default editor you need to go to the following location:

Site -> Global Configuration -> Default WYSIWYG Editor

There place on Editor TinyMCE and change it with Editor – JCE

Now go to edit some article, and you will see the difference in the editor 🙂

8. Add gallery Joomla capabilities with sigplus (Image Gallery Plus) and Very Simple Image Gallery

Image Gallery Plus sigplus Joomla Screenshot

Image Gallery Plus plugin (sigplus) gallery review screenshot

sigplus Image Gallery Plus is a straightforward way to add image or photo galleries to a Joomla article with a simple syntax. It takes a matter of minutes to set up a gallery but those who are looking for a powerful gallery solution will not be disappointed either: sigplus is suitable for both beginner and advanced users.

Download Sigplus Joomla Image Gallery plugin here
Using sigllus is quite easy all one has to do is use Joomla Media Manager from links:

Site -> Media Manager

Create new folder in the stories folder, let’s say New Pictures and further on use Media Manager to upload all desired pictures to be later displayed.

Being done with uploading the images you want to display, go to Article Manager :

Content -> Article Manager

From there choose your article where new uploaded pictures you want to display and type in the article:

{gallery}New Pictures{/gallery}.

Note that New Pictures is the directory just recently created as stated below, it’s important that there is no spacing between {gallery}and New Pictures, if one tries {gallery} New Pictures {/gallery} instead of {gallery}New Pictures{/gallery} an error will occur instead of the pictures being displayed in a scrolled gallery.

Sigplus Image Gallery has also a number of configuration options, which might make it look a bit more decent.
I have to say in my view the default way sigplus displays pictures is awful!

Another alternative if you don’t like Sigplus ‘s way of creating new galleries is to use Very Simple Image Gallery

Very Simple Image Gallery joomla screenshot

Here is a screenshot on a sample gallery created with Very Simple Image Gallery Joomla Plugin

You can download Very simple image gallery here

After installing the plugin. It’s use is analogous to the Sigplus . To use it likewise sigplus create new directory through Media Manager and in stories and upload your files in let’s say New Pictures1 . Later on in your article place, the code

{vsig}New Pictures1{/vsig}

Gallery will be generated automatically by the plugin. I think Simple Image Gallery is a bit more advanced and gives a better outlook to Galleries, though it’s configuration settings are much less than with SigPlus image gallery.

To add pictures comments e.g. img link alt=” and title=” tib you need to place a code within the Article manager similar to:

{vsig_c}0|Picture_1.JPG|Some sample text|Some other text{/vsig_c}
{vsig_c}0|Picture_2.JPG|Some example text|Some text{/vsig_c}
etc. ..

Note that the 0 in above example specifies the gallery number if you for instance are using a couple of galleries with Simple Image Gallery , the first one you used would be call 0 . The text specified as comments to the picture will also appear after you preview the gallery right below the picture when clicked on as a picture description in a really nice way.
9. Install Google maps plugin for Joomla

Google Maps plugin for Joomla screenshot

It’s a wise idea that every website has a location map on it’s website, for that reason Google maps is just great.
To install Google maps capability to joomla one can use a plugin called Google Maps .

You can straighly download Joomla’s Googlemap plugin from here

Afterwards use Extension Manager to install the plugin e.g. follow:

Extensions -&gr; Install/Uninstall (Choose File)

and click on Upload File & Install button.

To further enable and configure the Joomla Googlemap plugin you will have to go to the location:

Extensions -> Plugin Manager

Therein you will have to find and enable the Google Maps plugin which is to be found in the column named Plugin Manager
On my Joomla installation the plugin was located in the second page with modules, so if you don’t find the module on the listing with modules on the first page, make sure you scroll to the bottom of the page and click on Next button.

Therein in the list you will most likely notice Google Maps use the Enable button to enable it.

Next step is to configure the plugin, to do so press on the plugin name Google Maps
All configuration necessery here is to place Googlemaps API Key in the respective field (you will see it among config options).

Issuing a new Google Maps api key takes just few seconds, if you already have a gmail account just go to and take few seconds to issue the key.

You will get the key right on your gmail account after being issued (to repeat myself issuing takes few seconds so no worrier here).

One moreOnce having the key place it in the Googlemaps API Key field and configuring Address (which is one of the list of many options the plugin provides) you will be done with configuration.

To display a google map the location you just configured go to the Article Manager , select the article where you want the google maps location picture of your address to appear and type in the Article:

{mosmap|text='Exact street address location'|zoom='15'|zoomType='Large'|zoomNew='0'}

After you save the article a very nice Google map showing you the location’s streets will appear.
You can further conifgure a number of things related to the google map to appear, one thing you might want to play with is the zoom option which as you see in below’s code is equal to 15, e.g. zoom=’15’
Set it to another one if you want to regulate your googlemaps zoom level. For more thoroughful options take a look at the extensive plugin documentation.

10. Joomla Xmap (generating static HTML sitemap) Download Xmap from here , install it the usual plugin way.

Right after installation on the plugin succesful install screen you will notice the link component menu .
Clicking on the component menu you will be leaded to a page showing you few links Sitemap’s URL :

  • XML Sitemap:
  • HTML Sitemap:
  • News Sitemap:
  • Images Sitemap:

11. Add Joomla donate Paypal capabilities with Joomla PAYPAL DONATION MODULE

Paypal Donation Module Joomla Screenshot

Just recently I’ve written a a post on how to add a paypal donation capabilities to joomla, you can read my previous post here

12. Install Joomla RSForms Module (Advanced Joomla Forms Support)

Simple Joomla RsForm contact form

If you’re planning to add a complicated form support for Joomla, there are plenty of plugins, however one that was suggested by a friend of mine which is deep in Joomla world and moreover works good on my joomla installations is RSForms

Joomla – RSForms! is free to download and has great and easy interface to create new joomla forms.

At the time of writting I use these three RSForms components on new Joomla installations:

RSform Pro 1.1.0 com
Mod RsForm for Joomla 1.5
Mod Rsform list for Joomla

For latest release of RSForms! use the link

Installation is like any other module and is done through Extensions -> Install/Uninstall menu.

After installation, setting up a new form is available from the Joomla Menus:

Components -> RSform!Pro -> Manage Forms

I would not enter in details on how to edit the default RSForms or create a new RSForm. Just take some time and learn it by trying 😉

After the rsform is ready, to enable the new form, navigate to Joomla menus:

Menus -> Main Menu

Press the New button located in the buttons bar nearby the page header in the list of options in Select Menu item Type you will notice the RSForm!Pro as an option, press on it to establish the new form in the menus.

A follow up window will appear where one can set a Title: and Alias: for the new form as well as few other options.
After finalizing the settings press on Apply button to save the settings and the new form should appear in Joomla.

Probably there are many more handy plugins, which I’m missing here thus I’ll be glad if readers suggest some more helpful essential (must have plugins) for Joomla.
Feedback on this tutorial is very welcome!
Looking forward to hear for your opinions if my article was helpful to you 😉

Screenshot expanded menus on GNOME / KDE in Linux and BSD desktop

Thursday, June 19th, 2014


If you're using actively Linux or FreeBSD on Desktop PC and experimenting with software, taking personal notes, developing software for Linux, writting documentation, participating in free software community etc., you will certainly need use screenshot heavily.

Taking a screenshot in Linux is done in same way as in any modern operating system by using the Print Screen (PrtScr) button, however there are few Nuts & Bolts of Linux screenshotting, to take advantage of full power of screenshot creation (i.e. be able to do some screenshot customization) which are not offered by default screenshot utilities (GNOMEgnome-screenshot and KDE's KSnapshot)

Here are few useful Linux /BSD Screenshot Tips and Tricks:

If you have done screenshots of Linux running programs more than few times already, you have probably noticed the usual way to screenshot by pressing Print Screen (PrtScr) button to take snapshot of the expanded GNOME / KDE menu is not working. In that order of thought you probably wondered whether it is possible to take a screenshot of an expanded menus? As a Linux user, I've been asking myself this question too, and feeling irritated that  I cannot prepare screenshot of a GNOME running application expanded menu. I've found two ways (though there are probably many more to make screenshot of an expanded Linux menu). Here is how:

Create screenshot of running application expanded menus

1. Taking screenshot of expanded menu using the command line

As with everything in Linux, there aremultiple ways to make screenshot of expanded Linux menus.

  • Make timed screenshot of the screen scheduled to screenshot after a set number of seconds.

The quickest way for to screenshot expanded menu is to use gnome-panel-screenshot or ksnapshot from command line. It is interesting pressing Prt Sc kbd button in GNOME invokes gnome-screenshot and in KDE uses ksnapshot


gnome-panel-screenshot --delay 5


To not spend time running it from gnome-terminal (in GNOME desktop), press Alt+F2 (simultaneously) and use the Run Application command shortcut.


This will instruct Screenshot utility to wait for 5 seconds before capturing your desktop this should be enough time for you to go to navigate to expanded menu which you want to get screenshotted.


  • Make timed screenshot of the screen in GUI with GIMP


(If you're wonderhing what kind of Linux is on screenshot – this is Trisquel – Run Free! GNU / Linux. It is a Spanish distribution focused on providing 100% free software in it – without proprietary firmware or software. Trisquel is based on Debian and uses the dpkg / apt-get package managers. Trisquel is a recommended Linux to use by Richard Stallman and The Free Software Foundation).
To make timed screenshot with GIMP use menus:


File -> Create -> Screenshot



Chosee whether you want to Take screenshot of the entire screen or a Region to Grab and set your wanted Delay

Screenshot will be prepared on $HOME/Desktop, after set time.

Workrave – Preverve health from RSI (Computer caused Repetitive Strain Injury) on Linux and Windows

Tuesday, June 25th, 2013

Prevent and heal repetitive strain injury RSI with workrave on Windows and Linux

Huge part of people professions nowadays includes being in front of PC Screen for almost a day. Staying on computer is addictive and even after job is done many people came back in front of the PC screen to play some games or just read something. Many might not know that this computer hanging is a costly thing as it slowly reflects negative our health and living balance. For geeky people who work in IT profession the threat is even bigger as we ITs tend to spend even more time in front of computers. The risk therefore for catching RSI (Repetitive Strain Injury), whether you have to deal with computers daily is very real.

For those who hear for RSI for first time, here is what it is as described in Wikipedia:

Repetitive strain injuries (RSIs) are "injuries to the musculoskeletal and nervous systems that may be caused by repetitive tasks, forceful exertions, vibrations, mechanical compression, or sustained or awkward positions"

For more on RSI check out Wikipedia Article here.

Thanksfully RSI is possible to reverse as well as prevent by giving regular breaks from computer screen on timely base and even can be configured to limit time you will spend on the PC. 

Just recently I found out about existence of  Workrave – program which helps you in reminding, when you have to give breaks from computer and makes you limit yourself on how long you use the PC.

Workrave is available for both Windows and Linux OS.

debian:~# apt-cache show workrave | grep -i description -A 3

Description-en: Repetitive Strain Injury prevention tool
 Workrave is a program that assists in the recovery and prevention of
 Repetitive Strain Injury (RSI). The program frequently alerts you to
 take micro-pauses, rest breaks and restricts you to your daily limit.

To give it a try on Debian / Ubuntu Linux, install with usual:

debian:~# apt-get install --yes workrave

Launch it by running:

hipo@debian:~$ workrave

or via GNOME menus:

Applications -> Universal Access -> Workrave

Once launched Workrave applet appears right on in GNOME main panel. Below is screenshot of it.
Workrave applet in Gnome debian Linux screenshot

Clicking on the sheep image, there are plenty of configuration menus from which to choose how Workrave will further behave. Its default behavior is quite agressive and suggests breaks too often so if you choose to follow default configuration you will quickly be bored and probably remove it from computer. Hence re-configuring Workrave to remind for breaks every one hour is a good timing in my opinion:

Configuring workrave to remind for breaks from computer every one hour screenshot

Workrave time for micro break screenshot



Workrave includes reminder with neck movement exercises, which if followed can severely de-stress and keep your neck healthy.

The program has even statistics on how much breaks you take, how long it was used and various other interesting info, below is screenshot from statistics window:

Linux: Configure Midnight Commander to use mcedit instead of nano or vi text editor

Friday, June 21st, 2013

reverting mc text editor to mcedit fix problem with mcedit not working in linux

I use Midnight Commander console file manager on any UNIX like servers, since my early days as system administrator. mc comes with its own text editor mcedit which is often very handy for reading config files or pieces of source code. Many times I had to modify files which were spitting errors which I couldn't track in VIM, jor or whatever text editor had on server at hand and after checking file with mcedit I caught my config or source code mistake. I guess many other admins has similar nice experiences with mcedit Internal file editor of GNU Midnight Commander. Nowadays, I install mostly Debian Linux on new configured servers and using mc to navigate in file system is very useful. I prefer mc to open files for edit with F4 (Edit – kbd shortcut) with its default mcedit, however for some reasons most of Debian / Ubuntu and other Linuxes, nowadays has set global environment text editor to nano. I totally dislike this text editor and like changing mc always to use mcedit. This is done straight from MC menus by:

Pressing F9 -> Going to Options -> Configuration -> (Setting mark on) -> Use Inernal Edit

linux console file manager midnight commander use internal edit menu unchecked screenshot


Show / Restore missing Gimp 2.8 Toolbox Menu on Debian Wheezy 7.0 Linux

Tuesday, May 28th, 2013

After installing latest Debian Wheezy Linux on my Lenovo Thinkpad Notebook. One of first packages after very basic GNOME install was of course GIMP.

I edit images with GIMP mostly on daily basis, so life without GIMP is impossible…
Debian 7 comes with shiny new version of GIMP – GIMP 2.8. So far so good, but the problem is when started it for a first time, the default configuration is made in a way that it miss essential Gimp Panel Window (The Toolbox Window). Missing Brushes and selectors, move, scissors etc. is something really terrible.

My first guess was I can display it somehow from GIMP's View menu but after few minutes of try/errs I figured out this is not possible.

One menu I managed to displayed Toolbox in some mostly unusubale form, since they were not fitting well my 1024×768 resolution screen is via menus:

Windows -> Toolbox

Since this wasn't what I was looking for I spend some 10 minutes until I finally found "the fix". from menus:

Preferences -> Window Management -> Reset Saved Window Positions to Default Values

How to manually disable Windows Genuine Advantage on Windows XP SP2

Wednesday, May 25th, 2011

WGA Notification message popup message

I have a pirate version of Windows XP Pro 2 installer CD which does automatically turn on Windows Genuine Advantage

This is kind of annoying as the computer gets really slow and the hard disk drive activite gets intensive as well as an annoying popup message that the Windows XP copy is not genuine does appear periodically

In order to get rid of the message I had to do the following steps:

1. Get into Windows Safe Mode without Networking

As most of the people knows this is achieved by pressing F8 keyboard key right before the Windows bootup screen appears.

After in Safe mode it’s necessery to,

2. Run Windows Command Line (cmd.exe)

To do so follow, the menus:

Windows (Start Menu) -> Run -> cmd.exe

3. In the command prompt window issue the commands:

C:Documents and SettingsUser> cd WindowsSystem32
C:WindowsSystem32> taskkill -IM wgatray.exe
C:WindowsSystem32> del wgatray.exe
C:WindowsSystem32> move wgalogon.dll wgalogon.dll.old
C:WindowsSystem32> del wgalogon.dll.old

Something to mention is you have to be really quick, with deleting wgalogon.dll, cause wgatray.exe is scheduled to run every 1 / 2 seconds 🙂 It is a bit of situation of type “be quick or be dead” as Maiden used to sing 🙂
A Windows system restart and Hooray the Windows Genuine message is gone 🙂

deb Linux: How to add support for Bulgarian, Russian, Belarusian, Ukrainian, Serbian, Macedonian, Bosnian language cyrillic localization to Xfce, GNOME, KDE Desktop

Monday, March 18th, 2013

If just installed Ubuntu or Xubuntu and choose as a default language English by mistake and you happen to live in Bulgaria, Russia, Ukraine, Belarus or any other cyrillic speaking / writting country and you want to make the desktop graphical environment to display menus in mother language Cyrillic. Here is how;

To add cyrillic localization, native support in GUI environment for major Dsektop Graphic Environments (XFCE, GNOME, KDE …) run in terminal:

For Bulgarian Cyrillic language Desktop support:

linux:~# apt-get install language-pack-bg

Инсталиране на language-pack-bg-base (1:12.04+20130128) …
Generating locales…
  bg_BG.UTF-8… up-to-date
Generation complete.

Two packages language-pack-bg and language-pack-bg-base packages add to system localization files which in Linux are in the format of .mo files. Here is list of 2 packs file content:


linux:~# dpkg -L language-pack-bg



linux:~# dpkg -L language-pack-bg-base



Above .mo files are  binary files, generated from plain text .po / .pod files. In free software OS .po files are the most common language translation files, where for each different language a set of .po files exist. Translators usually translate from English to respective language using a GUI text editor called poedit. Once translation is made from those .po files .mo binaries are generated and shipped as localizations for program or group of programs. Below is edit of one of Polish translation of lang file belonging to CUPS Printing service.

poedit gnu linux xubuntu screenshot editing cups .po language plain text file

Once .po files are created, generation of .mo files can be done in various way, however usually Linux system uses msgfmt – (compile message catalog to binary format). In order to generate .mo file out of lets say cups_pl.po;

hipo@linux:~$ msgfmt
hipo@linux:~$ ls -al *.mo
-rw-rw-r-- 1 hipo hipo 31988 Mar 18 12:38

Anyways, here is how to add Cyrillic support for rest of Major cyrillic speaking countries, issue;

For Russian Cyrillic language Linux Desktop env support;

linux:~# apt-get install --yes language-pack-ru

For Belarusian Cyrillic Linux Desktop;

linux:~# apt-get install --yes language-pack-be

For Linux Desktop in Ukrainian;

linux:~# apt-get install --yes language-pack-uk

For Linux Desktop in Serbian language;

linux:~# apt-get install --yes language-pack-sr

For Graphic Environment in Macedonian;

linux:~# apt-get install --yes llanguage-pack-mk

For Linux GUI in Bosnian;

linux:~# apt-get install --yes language-pack-bs

For Kyrgyz language Linux localization;

linux:~# apt-get install --yes language-pack-ky

Whether, you are using Linux Desktop internationalization on some other Cyrillic related language, which I'm missing here please feel free to drop me a comment how you install it? I
