How to check if network ethernet cards are active on Linux server / detect the physical connected state of a network cable / connector?

Tuesday, November 1st, 2022

Lets say you are administrating some Linux server and need to upgrade a switch and temporary move out traffic for ethernet interfaces connected via a Gigabit network to a Gigabit Cisco / Junper EX Series / HPE Aruba or Arista Platform network switch to a newer version of a switch or software.

Usually if you don't have control over the Network switch (if you're employeed in a large corporation), that migration will be handled by a colleague from the Network team in a prescheduled time slot and usually in a coordinated meeting, once the cabling is being physically moved by someone a person in the Computer Room (in DC) in the respective data center.

Then once the correct commands are executed on the network switch to remap the new cable to point to the right location on the Linux server, where the old switch was and the setup has to be double verified by the network team mate.

Once this is done either by a colleague or if you're in a smaller company and you work as one man army sysadmin and you have done it yourself.
Next step is to verify that the Ethernet LAN cards on the Linux server lets say 6 or 8 LAN cards are still connected and active to the preset Active LAN / VLANs.

On Linux this is pretty simple and there is many ways to do it with external tools like ethtool, if you're lucky and your server doesn't have to have a paranoid security rules to follow or have to be a minimilastic machine with a 100% PCI High security standards compliancy.

To check connectivity for all your ethernet interfaces you can simply run a one liner shell script like so:

[root@linux-server ~]# for i in $(ip a s|grep -i :|grep -v link|awk '{ print $2 }'|sed -e 's#:##g'|grep -v lo); do ethtool $i; done
Settings for eth0:
        Link detected: yes
Settings for eth1:
        Link detected: yes
Settings for eth2:
        Link detected: yes

So far so good but what if your RHEL / CentOS / Debian server doesn't have ethtool installed and you're not allowed to install it then how can you check whether network cable connector is indicating a network activity to the connected Ethernet LAN cards?

[root@linux-server ~]# for f in $(ls -1 /sys/class/net/); do echo "Eth inface: $f"; cat /sys/class/net/$f/operstate; done
Eth inface: eth0
up
Eth inface: eth1
up
Eth inface: eth2
up
Eth inface: lo
unknown

If your operstate returns something different like state unknown, e.g.:

root@linux-server ~]# cd /sys/class/net/
[root@linux-server net]# grep "" eth2/operstate
unknown
[root@linux-server net]#

[root@linux-server net]# grep "" eth{0,1,2,3}/operstate  
eth0/operstate:unknown
eth1/operstate:unknown
eth2/operstate:unknown
eth3/operstate:unknown

Then you need to check the carrier file

[root@linux-server net]# grep "" eth{0,1,2,3}/carrier
eth0/carrier:1
eth1/carrier:1
eth2/carrier:1
eth3/carrier:1

It could return either 0 or 1

The number 1 in the above output means that the network cable is physically connected to your network card’s slot meaning your network switch migration is success.

Method 2: Next, we will test a second network interface eth1:

[root@linux-server net]# cat /sys/class/net/eth1/carrier
[root@linux-server net]# cat: /sys/class/net/eth1/carrier: Invalid argument

This command’s output most likely means the the eth1 network interface is in powered down state.

So what have learned?

We have learned how to monitor the state of the network cable connected to a Linux ethernet device via external switch that is migrated without the use of any external tools like ethtool.

xorg on Toshiba Satellite L40 14B with Intel GM965 video hangs up after boot and the worst fix ever / How to reinstall Ubuntu by keeping the old personal data and programs

Wednesday, April 27th, 2011

black screen ubuntu troubles

I have updated Ubuntu version 9.04 (Jaunty) to 9.10 and followed the my previous post update ubuntu from 9.04 to Latest Ubuntu

I expected that a step by step upgrade from a release to release will work like a charm and though it does on many notebooks it doesn't on Toshiba Satellite L40

The update itself went fine, whether I used the update-manager -d and followed the above pointed tutorial, however after a system restart the PC failed to boot the X server properly, a completely blank screen with blinking cursor appeared and that was all.

I restarted the system into the 2.6.35-28-generic kernel rescue-mode recovery kernel in order to be able to enter into physical console.

Logically the first thing I did is to check /var/log/messages and /var/log/Xorg.0.log but I couldn't find nothing unusual or wrong there.

I suspected something might be wrong with /etc/X11/xorg.conf so I deleted it:

ubuntu:~# rm -f /etc/X11/xorg.conf

and attempted to re-create the xorg.conf X configuration with command:

ubuntu:~# dpkg-reconfigure xserver-xorg

This command was reported to be the usual way to reconfigure the X server settings from console, but in my case (for unknown reasons) it did nothing.

Next the command which was able to re-generate the xorg.conf file was:

ubuntu:~# X -configure

The command generates a xorg.conf sample file in /root/xorg.conf.* so I used the conf to put it in /etc/X11/xorg.conf X's default location and restarted in hope that this would fix the non-booting issue.

Very sadly again the black screen of death appeared on the notebook toshiba screen.
I further thought of completely wipe out the xorg.conf in hope that at least it might boot without the conf file but this worked out neither.

I attempted to run the Xserver with a xorg.conf configured to work with vesa as it's well known vesa X server driver is supposed to work on 99% of the video cards, as almost all of them nowdays are compatible with the vesa standard, but guess what in my case vesa worked not!

The only version of X I can boot in was the failsafe X screen mode which is available through the grub's boot menu recovery mode.

Further on I decided to try few xorg.conf which I found online and were reported to work fine with Intel GM965 internal video , and yes this was also unsucessful.

Some of my other futile attempts were: to re-install the xorg server with apt-get, reinstall the xserver-xorg-video-intel driver e.g.:

ubuntu:~# apt-get install --reinstall xserver-xorg xserver-xorg-video-intel

As nothing worked out I was completely pissed off and decided to take an alternative approach which will take a lot of time but at least will probably be succesful, I decided to completely re-install the Ubuntu from a CD after backing up the /home directory and making a list of available packages on the system, so I can further easily run a tiny bash one-liner script to install all the packages which were previously existing on the laptop before the re-install:

Here is how I did it:

First I archived the /home directory:

ubuntu:/# tar -czvf home.tar.gz home/
....

For 12GB of data with some few thousands of files archiving it took about 40 minutes.

The tar spit archive became like 9GB and I hence used sftp to upload it to a remote FTP server as I was missing a flash drive or an external HDD where I can place the just archived data.

Uploading with sftp can be achieved with a command similar to:

sftp user@yourhost.com
Password:
Connected to yourhost.com.
sftp> put home.tar.gz

As a next step to backup in a file the list of all current installed packages, before I can further proceed to boot-up with the Ubuntu Maverich 10.10 CD and prooceed with the fresh install I used command:

for i in $(dpkg -l| awk '{ print $2 }'); do
echo $i; done >> my_current_ubuntu_packages.txt

Once again I used sftp as in above example to upload my_current_update_packages.txt file to my FTP host.

After backing up all the stuff necessery, I restarted the system and booted from the CD-rom with Ubuntu.
The Ubuntu installation as usual is more than a piece of cake and even if you don't have a brain you can succeed with it, so I wouldn't comment on it 😉

Right after the installation I used the sftp client once again to fetch the home.tar.gz and my_current_ubuntu_packages.txt

I placed the home.tar.gz in /home/ and untarred it inside the fresh /home dir:

ubuntu:/home# tar -zxvf home.tar.gz

Eventually the old home directory was located in /home/home so thereon I used Midnight Commander ( the good old mc text file explorer and manager ) to restore the important user files to their respective places.

As a last step I used the my_current_ubuntu_packages.txt in combination with a tiny shell script to install all the listed packages inside the file with command:

ubuntu:~# for i in $(cat my_current_ubuntu_packagespackages.txt); do
apt-get install --yes $i; sleep 1;
done

You will have to stay in front of the computer and manually answer a ncurses interface questions concerning some packages configuration and to be honest this is really annoying and time consuming.

Summing up the overall time I spend with this stupid Toshiba Satellite L40 with the shitty Intel GM965 was 4 days, where each day I tried numerous ways to fix up the X and did my best to get through the blank screen xserver non-bootable issue, without a complete re-install of the old Ubuntu system.
This is a lesson for me that if I stumble such a shitty issues I will straight proceed to the re-install option and not loose my time with non-sense fixes which would never work.

Hope the article might be helpful to somebody else who experience some problems with Linux similar to mine.

After all at least the Ubuntu Maverick 10.10 is really good looking in general from a design perspective.
What really striked me was the placement of the close, minimize and maximize window buttons , it seems in newer Ubuntus the ubuntu guys decided to place the buttons on the left, here is a screenshot:

Left button positioning of navigation Buttons in Ubuntu 10.10

I believe the solution I explain, though very radical and slow is a solution that would always work and hence worthy 😉
Let me hear from you if the article was helpful.

How to show country flag, web browser type and Operating System in WordPress Comments

Wednesday, February 15th, 2012

!!! IMPORTANT UPDATE COMMENT INFO DETECTOR IS NO LONGER SUPPORTED (IS OBSOLETE) AND THE COUNTRY FLAGS AND OPERATING SYSTEM WILL BE NOT SHOWING INSTEAD,

!!!! TO MAKE THE COUNTRY FLAGS AND OS WP FUNCTIONALITY WORK AGAIN YOU WILL NEED TO INSTALL WP-USERAGENT !!!

I've come across a nice WordPress plugin that displays country flag, operating system and web browser used in each of posted comments blog comments.
Its really nice plugin, since it adds some transperancy and colorfulness to each of blog comments 😉
here is a screenshot of my blog with Comments Info Detector "in action":

Example of Comments Info Detector in Action on wordpress blog comments

Comments Info Detector as of time of writting is at stable ver 1.0.5.
The plugin installation and configuration is very easy as with most other WP plugins. To install the plugin;

1. Download and unzip Comments Info Detector

linux:/var/www/blog:# cd wp-content/plugins
linux:/var/www/blog/wp-content/plugins:# wget http://downloads.wordpress.org/plugin/comment-info-detector.zip
...
linux:/var/www/blog/wp-content/plugins:# unzip comment-info-detector.zip
...

Just for the sake of preservation of history, I've made a mirror of comments-info-detector 1.0.5 wp plugin for download here
2. Activate Comment-Info-Detector

To enable the plugin Navigate to;
Plugins -> Inactive -> Comment Info Detector (Activate)

After having enabled the plugin as a last 3rd step it has to be configured.

3. Configure comment-info-detector wp plugin

By default the plugin is disabled. To change it to enabled (configure it) by navigating to:

Settings -> Comments Info Detector

Next a a page will appear with variout fields and web forms, where stuff can be changed. Here almost all of it should be left as it is the only change should be in the drop down menus near the end of the page:

Display Country Flags Automatically (Change No to Yes)
Display Web Browsers and OS Automatically (Change No to Yes

Comments Info Detector WordPress plugin configuration Screenshot

After the two menus are set to "Yes" and pressing on Save Changes the plugin is enabled it will immediately start showing information inside each comment the GeoIP country location flag of the person who commented as well as OS type and Web Browser 🙂

Auto restart Apache on High server load (bash shell script) – Fixing Apache server temporal overload issues

Saturday, March 24th, 2012

auto-restart-apache-on-high-load-bash-shell-script-fixing-apache-temporal-overload-issues

I've written a tiny script to check and restart, Apache if the server encounters, extremely high load avarage like for instance more than (>25). Below is an example of a server reaching a very high load avarage:;

server~:# uptime
13:46:59 up 2 days, 18:54, 1 user, load average: 58.09, 59.08, 60.05
load average: 0.09, 0.08, 0.08

Sometimes high load avarage is not a problem, as the server might have a very powerful hardware. A high load numbers is not always an indicator for a serious problems. Some 16 CPU dual core (2.18 Ghz) machine with 16GB of ram could probably work normally with a high load avarage like in the example. Anyhow as most servers are not so powerful having such a high load avarage, makes the machine hardly do its job routine.

In my specific, case one of our Debian Linux servers is periodically reaching to a very high load level numbers. When this happens the Apache webserver is often incapable to serve its incoming requests and starts lagging for clients. The only work-around is to stop the Apache server for a couple of seconds (10 or 20 seconds) and then start it again once the load avarage has dropped to less than "3".

If this temporary fix is not applied on time, the server load gets increased exponentially until all the server services (ssh, ftp … whatever) stop responding normally to requests and the server completely hangs …

Often this server overloads, are occuring at night time so I'm not logged in on the server and one such unexpected overload makes the server unreachable for hours.
To get around the sudden high periodic load avarage server increase, I've written a tiny bash script to monitor, the server load avarage and initiate an Apache server stop and start with a few seconds delay in between.

#!/bin/sh
# script to check server for extremely high load and restart Apache if the condition is matched
check=`cat /proc/loadavg | sed 's/\./ /' | awk '{print $1}'`
# define max load avarage when script is triggered
max_load='25'
# log file
high_load_log='/var/log/apache_high_load_restart.log';
# location of inidex.php to overwrite with temporary message
index_php_loc='/home/site/www/index.php';
# location to Apache init script
apache_init='/etc/init.d/apache2';
#
site_maintenance_msg="Site Maintenance in progress - We will be back online in a minute";
if [ $check -gt "$max_load" ]; then>
#25 is load average on 5 minutes
cp -rpf $index_php_loc $index_php_loc.bak_ap
echo "$site_maintenance_msg" > $index_php_loc
sleep 15;
if [ $check -gt "$max_load" ]; then
$apache_init stop
sleep 5;
$apache_init restart
echo "$(date) : Apache Restart due to excessive load | $check |" >> $high_load_log;
cp -rpf $index_php_loc.bak_ap $index_php_loc
fi
fi

The idea of the script is partially based on a forum thread – Auto Restart Apache on High Load – http://www.webhostingtalk.com/showthread.php?t=971304Here is a link to my restart_apache_on_high_load.sh script

The script is written in a way that it makes two "if" condition check ups, to assure 100% there is a constant high load avarage and not just a temporal 5 seconds load avarage jump. Once the first if is matched, the script first tries to reduce the server load by overwritting a the index.php, index.html script of the website with a one stating the server is ongoing a maintenance operations.
Temporary stopping the index page, often reduces the load in 10 seconds of time, so the second if case is not necessery at all. Sometimes, however this first "if" condition cannot decrease enough the load and the server load continues to stay too high, then the script second if comes to play and makes apache to be completely stopped via Apache init script do 2 secs delay and launch the apache server again.

The script also logs about, the load avarage encountered, while the server was overloaded and Apache webserver was restarted, so later I can check what time the server overload occured.
To make the script periodically run, I've scheduled the script to launch every 5 minutes as a cron job with the following cron:

# restart Apache if load is higher than 25
*/5 * * * * /usr/sbin/restart_apache_on_high_load.sh >/dev/null 2>&1

I have also another system which is running FreeBSD 7_2, which is having the same overload server problems as with the Linux host.
Copying the auto restart apache on high load script on FreeBSD didn't work out of the box. So I rewrote a little chunk of the script to make it running on the FreeBSD host. Hence, if you would like to auto restart Apache or any other service on FreeBSD server – get /usr/sbin/restart_apache_on_high_load_freebsd.sh my script and set it on cron on your BSD.

This script is just a temporary work around, however as its obvious that the frequency of the high overload will be rising with time and we will need to buy new server hardware to solve permanently the issues, anyways, until this happens the script does a great job 🙂

I'm aware there is also alternative way to auto restart Apache webserver on high server loads through using monit – utility for monitoring services on a Unix system. However as I didn't wanted to bother to run extra services in the background I decided to rather use the up presented script.

Interesting info to know is Apache module mod_overload exists – which can be used for checking load average. Using this module once load avarage is over a certain number apache can stop in its preforked processes current serving request, I've never tested it myself so I don't know how usable it is. As of time of writting it is in early stage version 0.2.2
If someone, have tried it and is happy with it on a busy hosting servers, please share with me if it is stable enough?

How rescue unbootable Windows PC, Windows files through files Network copy to remote server shared Folder using Hirens Boot CD

Saturday, November 12th, 2011

hirens-boot-cd-logo-how-to-rescue-unbootable-pc-with-hirens-bootcd
I'm rescuing some files from one unbootable Windows XP using a livecd with Hirens Boot CD 13

In order to rescue the three NTFS Windows partitions files, I mounted them after booting a Mini Linux from Hirens Boot CD.

Mounting NTFS using Hirens BootCD went quite smoothly to mount the 3 partitions I used cmds:

# mount /dev/sda1 /mnt/sda1
# mount /dev/sda2 /mnt/sda2
# mount /dev/sdb1 /mnt/sdb1

After the three NTFS file partitions are mounted I used smbclient to list all the available Network Shares on the remote Network Samba Shares Server which by the way possessed the NETBIOS name of SERVER 😉

# smbclient -L //SERVER/
Enter root's password:
Domain=[SERVER] OS=[Windows 7 Ultimate 7600] Server=[Windows 7 Ultimate 6.1]

Sharename Type Comment
——— —- ——-
!!!MUSIC Disk
ADMIN$ Disk Remote Admin
C$ Disk Default share
Canon Inkjet S9000 (Copy 2) Printer Canon Inkjet S9000 (Copy 2)
D$ Disk Default share
Domain=[SERVER] OS=[Windows 7 Ultimate 7600] Server=[Windows 7 Ultimate 6.1]
Server Comment
——— ——-
Workgroup Master
——— ——-

Further on to mount the //SERVER/D network samba drive – (the location where I wanted to transfer the files from the above 3 mounted partitions):

# mkdir /mnt/D
# mount //192.168.0.100/D /mnt/D
#

Where the IP 192.168.0.100 is actually the local network IP address of the //SERVER win smb machine.

Afterwards I used mc to copy all the files I needed to rescue from all the 3 above mentioned win partitions to the mounted //SERVER/D

Prism on Linux a way to turn any Web site location into a Desktop application

Wednesday, September 23rd, 2009

I was googling for some cool features to enrich my Google desktop while I found an applicaiton whichis said to be helpful.
It’s called Prism and is a Mozilla Lab experiment project. Actually it’s nothing special.
It creates a simple window in which it can visualize a website making it look exactly like your desktopapplications.
It has a couple of possiblities like creating a desktop icon for your website, enablesome kind of navigation keys, show status messages on what’s happening on the desktop embeded application andshow navigation bars.
The project is said to be a revolutionary next step towards integrating the webwith your desktop
. You can check out Prism’s website further on On mozilla’s prism website . It might be interesting for you to check out Prism in action before you might go for a try on Youtube here .
Prism is both available via Firefox extension or a desktop application both of which provides you with the describedabove prism functionality. As a Debian user you might wonder if prism is available as a debian package, well there is one
, even though it’s not a release part of the offician debian package distribution. If you’d like to test prismvia it’s debian package use the following prism deb package
,anyways the downside of using the 0.9 debian package is that you won’t be running prism’s latest release.
If you’d like to be running the latest prism version please download it from mozilla’s website.
Well enough talk let me tell you my personal view on Prism. It’s a COMPLETE BULLSHIT! 🙂 I don’t see how any geek wouldhave benefit of the app neither, how does it bridge in the web with the desktop.
It’s simply a crap that could takeof your daily lifetime to install and review 🙂

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:

Joomla file explorer extplorer module

Installing and using the plugin is a piece of cake. To install the plugin:

a. download Joomla file Xplorer from here or from the official plugin website.

b. Install the plugin through the admin joomla menu:

Extensions -> Install/Uninstall

c. Start using the newly installed plugin by following to menus:

Components -> eXtplorer

2. JCrawler Generate easily sitemap.xml to aim the overall Joomla website SEO optimization

JCrawler logo plugin joomla

I have previously written a very through tutorial on how to install configure and generate website sitemap with Jcrawler module, You can read my article titled: How to build website sitemap.xml in Joomla here

3. sh404SEF – Make your Joomla links and content more user friendly

sh404sef Joomla Search Engine Optimization plugin

sh404SEF is a great Joomla plugin, which will seriously improve SEO and could contribute well for a website to be better indexed with major search engines.

I have previously written an article describing thoroughfully the install and use procedures for the module.
You can read the article Making your Joomla URLS Google friendly with sh404sef plugin / Simple Joomla link SEO here

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

a. Download the Google Analytics Tracking Module
The module is available from Joomla Extensions on joomla.org

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

b. Install the Google Analytics Tracking Module;
Login as joomla admin and navigate to;

Extensions -> Install

Place the analytics_tracking15.zip url to the Install URL: field.
Again as of time of writting you need to place https://www.pc-freak.net/files/analytics_tracking15.zip;

c. Open the Module Manager

Extensions -> Module Manager

d. Click over Google Analytics Tracking Module
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.
As a last step before the Google analytics is set-up on the Joomla you need to enable the plugin to do you need to press over the tick left sided from the text reading Google Analytics Tracking Module in the Module Manager
e. Click over the Enabled button in Module Manager;
Google Analytics Tracking Module -> Enabled

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 http://itprism.com/free-joomla-extensions/social-buttons-plugin 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:
 

  • Delicios.com
  • Digg.com
  • 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

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 http://code.google.com/apis/maps/signup.html 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:

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 http://www.rsjoomla.com/joomla-components/rsform.html

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 😉

How to easy add Joomla 1.5 donate Paypal capabilities with Joomla PAYPAL DONATION MODULE

Wednesday, June 15th, 2011

PayPal donation Module Joomla Screenshot

Many joomla CMS installations are for Non-profit organizations or Non Government organizations. These are organizations which are not officially making profit and therefore this instituations are interested into donations to support their activities.

In this occasions adding Joomla paypal capabilities is very essential. There are plenty of modules which enables Joomla to support paypal monetary payments, however many of them are either paid or requires registration and thus it’s quite time consuming to set up a decent PayPal supporting module for Joomla.
After a bit of investigation thanks God, I’ve come across a module that is free of charge, easily downloadable (wihtout registration) and is also relatively easy to configure, these module is called PAYPAL DONATION MODULE
I’ve mirored the module to my server, just in case if the module disappears in the future.

Here are a very brief explanation on how the module can be downloaded installed and configured:

First Download (mod_ojdonation_pp) Paypal Donation Module here

Install it as joomla module via:

Extensions -> Install/Uninstall
menu

Afterwards, go to:

Extensions -> Module Manager

In the list of modules you will notice the Donate module which will be disabled. Use the Enable button to enable it.

Next by clicking on the Donate Module Name, one can configure the module, where the most essential configuration values that needs to be filled in are:

1. Title: – The title of the donation form:
2. Donation Title: – Title of donation picture to show in the webpage
3. Donation Amount: – Default donation amount user will donate with paypal by clicking on Donate button
4. Currency – Default currency the donators will use to donate to configured paypal account
5. Paypal ID: – The email address of paypal account your donators will donate to (This was a bit hard to understand since Paypal ID is not a number ID but the email address configured as an username in PayPal).
6. Donation Description: – Description text to appear before the Donate button
7. Donation Footer: – Text to appear after the Donate button

There are two ways one could add the donation module to show the donation form, on the joomla website:
a. One is to enable the donation button on every joomla webpage (I don’t like this kind of behaviour).

To use this kind of donate button display approach, you will have to select from the Donation module, conf options:
– Show on FrontPage: and Show Title:

Also make sure the Enabled: option is set to Yes

b. Second approach is to set the PayPal Donation form only to appear on a single menu, to do so:

While in Paypal Donation Module configuration in Menu Assignment section, select:

Select Menu Item(s) from the List
instead of the default All value set for Menus.

The last setting to be choosen is the paypal donation form page location (where exactly on the selected pages the form will appear).

The form location is set from the Position: dropdown menu, the option which I found to be the best one for me was the bottom option. However just play with the Position setting and choose the one that will be best for you.

Then scroll on in the Menu Selection: and choose only the menus where you want a paypal donation form to appear.

Finally to save all the recent made settings, click on Apply and refreshing in a new page should show you paypal’s money donation form in joomla

If all is configured fine with Joomla’s – Paypal Donation Module you should get on your webpage:
