Ubuntu 9.04 Jaunty on Toshiba L300 PLSBGE Laptop

Sunday, September 20th, 2009

Reading Time: 2minutes


Today I had the task to Install Ubuntu GNU / Linux on Toshiba L300 PLSBGE Laptop.

I had already installed Windows Vista Enterprise on the notebook. Thus I used Acronis Disk Directory Suite to partition the harddrive for Ubuntu even though I could have used the gparted included on Ubuntu’s installation CD. I’ve asked specificly if
I could use the Ubuntu CD to repartition my hard drive in #ubuntu in
The answer was positive it’s absolutely safe to resize an NTFS partition using Ubuntu’s installation LiveCD and gparted.That seems like a good news for all of us the free software users / enthusiasts / hobbyists etc.
I hated the default Ubuntu behaviour it automatically decided to install itself on a automatically created 2.5 GB partition.
I thought it won’t be so dumb to install itself on such a tiny partition. Well guess what I was wrong IT WAS SO DUMB!
Even though I had already 80 GB ext3 partition. Ubuntu’s default behaviour was to install on an automatically created 2.5GB partition.
Right after the installation I was stunned just to realize there was no free space on the drive where the dumbass installed itself.
After that I had some issues deleting the already cretead partitions, which for some reason messed up. Luckily the good old fdisk fixed the situation so I could easily delete all the partitions except the vista and recreate them again using gparted with Ubuntu’s install LiveCD. The install was completely flawless. Everything worked out of the box, no external efforts to fix broken stuff like usually happens in Linux fantastic! The only broken thing was that switching to plain console with ctrl+alt+f1 would visualize a non working display output and I couldn’t see the ttys at all. That wasn’t such a hassle since the system is planned to work only in GUI mode. I guess Ubuntu is going through a real development with a positive end results. Even external USB printer Canon PIXMA IP3300 worked by simply plugging it in. For some weird reason to make the printer work correctly I had to use driver for Canon PIXMA IP3000. Anyways it worked with it and the printer started printing correctly even though officially on some of the linux printers databases it’s reported the printer won’t work correctly never ever.END—–

Fixing enter not working in Skype 6 – Skype cannot send message bug on Windows XP

Skype how to fix enter not sending messages in Skype6 downgrade to Skype5 windows XP
Yesterday, I had to fix another Windows XP computer infested with Spyware and Viruses. Thanksfully I cleaned it up as usual using standard combination of Malware Bytes + LittleRegistry Cleaner and Avira. The PC haven't been updated recently and running still Windows XP SP2, thus to make Avira running I had to install SP3 as Avira nowdays depends on Win SP3. After clean up it worked much better, though it is not 100% sure if some kind of malicious software is still not on PC.
After all seemed fine on this Russian Windows XP, there was one thing still problematic – Skype. For some weird reason whenever user from Skype contact list is messaged, it was impossible to send the message with Enter key. I tried checking if all seems fine in Keyboard Settings and Regional Settings in Windows Control Center, cause XP version was with Russian Language Pack and I suspected the Language Pack might mess up something in how Keyboard keys are mapped but all seemed fine there. One important note to make here is PC is running on old hardware and had an old standard PS/2 Keyboard detected as PS/2 – 101 – 102 keys standard keyboard. I tried re-installing the keyboard driver, trying to auto-detect however driver detected for this keyboard seemed to be latest issued for PS/2 Keyboards from Microsoft so after update Skype can't send message bug was still present and respectively the only way to communicate with people from contact list was to Call the person and speak. I researched online on the problem and found a multitude of users complaining to face the same Skype messaging – Enter key not working, unfortunately noone online seemed to have found a solution. I've seen some suggestions to use Skype settings to re-map Enter key but on this Skype the option to remap how Enter key reacts wasn't present. Thus I decided to try to downgrade Skype 6 to Skype 5 here is a mirror of Skype 5 -and try if this helps. After Uninstalling Skype 6 and installing Skype 5 – enter key started working again so mission accomplished 🙂 If you happen to have the annoying Enter key not working in skype bug just downgrade to any below version to 6 and all will be fine. Drop me a comment if you experience the same bug with Win and Skype version.
Finally, be sure not to upgrade further Skype to avoid problems. Last but not least, there is even some advantages in older skype releases, the interface is simpler – making work with skype easier.

Convert WAV to MP3 in command line with LAME on Linux

Friday, April 8th, 2011

Reading Time: < 1minute
I needed to convert a bunch of files from WAV to MP3 format on my Linux desktop.

I’ve placed all my wav files to the directory /home/hipo/wav

And then I issued the small one liner script to convert the .wav files to .mp3 using the niftly lame linux mp3 convertor.

Here is how I did it:

linux-desktop:~$ cd wav
linux-desktop:/home/hipo/wav$ for i in *.wav; do
new_name=$(echo $i |sed -e 's#wav#mp3#g');
lame -V0 -h -b 160 --vbr-new "$i" "$new_name";

After executing the little script you might go and have a coffee, if you have thousands of files, each file convertion takes about 10-15 seconds of time (speed depends on your CPU).

Here is some output from a lame convertion to mp3 taking place:

Encoding as 8 kHz single-ch MPEG-2.5 Layer III VBR(q=0)
Frame | CPU time/estim | REAL time/estim | play/CPU | ETA
27237/27237 (100%)| 0:12/ 0:12| 0:12/ 0:12| 155.89x| 0:00
64 [27237] ***************************************************************
kbps mono % long switch short %
64.0 100.0 84.1 8.9 7.0
If you want to save my convertion quickly for a later, download my Convert WAV to mp3 from a directory with lame shell script here

Actually there are plenty of other ways to convert wav to mp3 on Linux through mplayer, ffmpeg even with mpg123.

There are also some GUI programs that could do the convertion like winff , however for some weird reason after installing WinFF on my debian it was not able to complete convertion to mp3?!
But it doesn’t matter, the good news is I did what I wanted to via the simple lame program and the above script, hope it helps somebody out there.

How to configure manually static IP address on Debian GNU/Linux / How to fix eth0 interface not brought up with error (networking restart is deprecated)

Friday, July 29th, 2011

Reading Time: 2minutes
I’ve recently had to manually assign a static IP address on one of the servers I manage, here is how I did it:             

debian:~# vim /etc/network/interfaces

Inside the file I placed:

# The primary network interface
allow-hotplug eth0
auto eth0
iface eth0 inet staticaddress

The broadcast and gateway configuration lines are not obligitory.
dns-nameservers would re-create /etc/resolv.conf file with the nameserver values specified which in these case are Google Public DNS servers and OpenDNS servers.

Very important variable is allow-hotplug eth0
If these variable with eth0 lan interface is omitted or missing (due to some some weird reason), the result would be the output you see from the command below:

debian:~# /etc/init.d/networking restart
Running /etc/init.d/networking restart is deprecated because it may not enable again some interfaces ... (warning).
Reconfiguring network interfaces...

Besides the /etc/init.d/networking restart is deprecated because it may not enable again some interfaces … (warning). , if the allow-hotplug eth0 variable is omitted the eth0 interface would not be brough up on next server boot or via the networking start/stop/restart init script.

My first reaction when I saw the message was that probably I’ll have to use invoke-rc.d, e.g.:
debian:~# invoke-rc.d networking restart
Running invoke-rc.d networking restart is deprecated because it may not enable again some interfaces ... (warning).

However as you see from above’s command output, running invoke-rc.d helped neither.

I was quite surprised with the inability to bring my network up for a while with the networking init script.
Interestingly using the command:

debian:~# ifup eth0

was able to succesfully bring up the network interface, whether still invoke-rc.d networking start failed.

After some wondering I finally figured out that the eth0 was not brought up by networking init script, because auto eth0 or allow-hotplug eth0 (which by the way are completely interchangable variables) were missing.

I added allow-hotplug eth0 and afterwards the networking script worked like a charm 😉

How to set custom page titles in Joomla 1.5 manually for better SEO

Thursday, June 2nd, 2011

Reading Time: 2minutes
he Joomla CMS default behaviour is that Page titles of the Joomla Articles created are always set to the page Title assigned to each of the articles.

This is not very good behaviour in terms of SEO, as the page title of each link on the main page is different and there is no continuous repeating pattern in all of the joomla pages.
Everyone that has even basic idea of SEO knows that page titles are very important weight factor to make indexing inside Search Engines succesful.

There is a well know SEO rule which is the more reoccuring pattern one has in his page titles, more is stressed on the keywords contained in the title.
As I said for some weird reason Joomla has no common page Title for all my the created Article pages linked via the Main Menu*

Thus in order to improve this bad default Joomla SEO behaviour one has to change the default auto assigned titles for created pages, manually.

Two things are necessery to change each of the joomla already existing TITLES.

1. Go to each of the pages (.e.g. Home etc.) and change the Parameters System Page Title settings

After logging in with administrator in Joomla, navigate to Menus -> Main Menu*

Further on choose a menu item from all your existing items, let’s say Home and click on it.

On the left side below the Save, Apply, Close and Help buttons you will notice the menus:

Parameters (Basic), Parameters (Component), Parameters (System)

When clicked on Parameters (System) a submenu will appear:
Joomla Main Menu Parameters System Page Title better SEO

Above is a screenshot of the up-described Parameters (System) [Page Title] location

You need to change where it reads on the screenshot CHANGE THE TITLE HERE !!!!!! 😉

After entering your own desired page title go and save the article via the Apply or Save button (also visible in the screenshot).

Now as the custom Page Title is set, next step is to enable the custom Page Title for the respective Article in Article Manager

2. Enable custom Page Title for created pages in Joomla

Go to the Article Manager by following the menus:

Content -> Article Manager

Select the Article of which you want to change the Page Title to some custom text and click over it.

As the article opens for edit in an html editor, navigate to Parameters (Advanced) tab and therein change the Show Title from default setting value:
Use Global

Once again use the Save or Apply button to confirm the new settings and open your website in a new tab, try to browse and check the title of the articles parameters just edited. It should show up in the Title (page heading) the custom input Title.

Now repeat the same procedure for all pages (Articles), existing in Joomla to attune the Page Titles to some Google friendly strings and enjoy the better Search engine indexing which should likely follow.

How to install Nvidia GeForce FX 5500 on Ubuntu 11.04

Tuesday, July 19th, 2011

Reading Time: 3minutesNvidia Tux GeForce GNU / Linux

Yesterday I was at a friend of mine who has recently installed Ubuntu 11.04 to his already oldish Desktop computer.

The system was 1.4Ghz (amd) with 512 RAM and some kind of Dell Trinitron 19 inch monitor
Even though he tried hard to make his NVIDIA GeForce FX 5500 ‘s drive to work properly with Ubuntu Natty Narwhal, he just has messed it even more.
As I always like helping people and I’m joyful for people who want to migrate to Linux, I took some time to make his NVIDIA GeForce work with this Ubuntu release.

First I tried to make it work by using some of the official NVIDIA Linux drivers located on following some online tutorial for Ubuntu claiming that it works but actually it didn’t, so finally after a bit of experimentation I found a way to make this video card work.
Here is how:

1. Install the following Ubuntu packages

root@ubuntu:~# apt-get install nouveau-firmware nvidia-173 nvidia-173-kernel-source
nvidia-cg-toolkit nvidia-common nvidia-current nvidia-glx-173 nvidia-settings

2. Load in the kernel and set to be auto loaded on boot nvidia’s driver kernel module nvidia-173

root@ubuntu:~# depmod -a;
root@ubutnu:~# modprobe nvidia-173
root@ubuntu:~# echo nvidia-173 >> /etc/modules

3. Stop temporary (Gnome dipsplay manager) gdm

root@ubuntu:~# service gdm stop

4. Use nvidia-xconfig to generate a working version of /etc/X11/xorg.conf for Nvidia

root@ubuntu:~# nvidia-xconfig

nvidia-xconfig will generate new /etc/X11/xorg.conf configuration corresponding to the Nvidia GeForce Fx 5500 and will move the old xorg.conf to xorg.conf.backup.

5. Start the gdm manager to be running again

root@ubuntu:~# service gdm start

Now the Xserver will start in a terrible mode of 640×480, probably because Ubuntu was unable to define correct VerticalSync and HorizontalSync for the 19 inch Dell Trinitron monitor or for some other weird reason, to fix this it’s quite easy though.
The fix to the NVIDIA GeForce 5500 running in 640×480 mode is done straigh via Gnome menus.

6. Use Gnome’s System -> Preferences -> Monitors to set raise up the Xserver resolution

Navigate to Gnome’s menus:

System -> Preferences -> Monitors

Gnome System Preferences Monitors Nvidia GeForce 5500 Ubuntu

Here you will have to select more appropriate resolution and a different refresh rate, which in my case was 1024×768 and further on to store the settings press the Apply button.

One oddity here was that according to the Monitor Preferences the refresh rate was running on 54 Hz which I don’t believe was the case as I guess it’s some kind of Gnome or Ubuntu bug. I changed the 54 Hz Refresh Rate to 50 Hz as using the 54 Hz refresh rate as the screen had a minor vibrations observable if one takes a thorough look on the screen.

Setting the NVIDIA GeForce 5500 driver to work with 50 Hz Refresh Rate in Gnome loooked like the Windows’s 85 Hz RR and looked quite nice so I left it this way.

Finally to test the newly installed driver 3D acceleration I used glxgears.

7. Install glxgears in order to be able to test that 3D acceleration on Nvidia works fine

root@ubuntu:~# apt-get install mesa-utils

After installing mesa-utils which nowdays contains glxgears executable one needs to execute the glxgears binary.

root@ubuntu:~# glxgears

Immediately after a window containing the glxgears should popup on the screen, like shown in below screenshot
Benchmark 3d Acceleration Linu glxgears

glxgears showed 3d acceleration works fine as the performance for 3d rendering shown was quite good and therefore 3D acceleration was running fine.

And that was it now the video works like and my friends, can enjoy the fun to have a generally virus Free OS 😉

How to fix clamd “ERROR: LOCAL: Socket file /tmp/clamd.socket is in use by another process.”

Monday, May 23rd, 2011

Reading Time: < 1minute
One of the Qmail server installations I’m taking care of’s clamd antivirus process started loading the system heavily.
After a bit of log reading and investigation I’ve found the following error in my /var/log/clamd/current

@400000004dda1e1815cf03f4 ERROR: LOCAL: Socket file /tmp/clamd.socket is in use by another process.

I’ve noticed in my process list that actually I do have two processes clamd :

11608 ? Sl 0:05 /usr/local/sbin/clamd
11632 ? S 0:00 /usr/bin/multilog t /var/log/clamd
16013 ? Sl 0:06 /usr/local/sbin/clamd

It appeared that for some weird reason one of the clamd process was failing to connect constantly to the clam server socket /tmp/clamd.socket and each time it tried to connect and failed to connect to the socket the system gets about 5% of extra load …

Resolving the issues was a piece of cake, all I had to do is stop the clamd server delete the /tmp/clamd.socket and relaunch the clamd server.

Here is exactly the commands I issued:

debian:~# cd /service/
debian:/service# svc -a clamd
debian:/service# svc -h clamd
debian:/service# svc -d clamd
debian:/service# rm -f /tmp/clamd.socket
debian:/service# svc -u clamd

Afterwards the clamd extra load went out and in /var/log/clamd/current I can see clamd loads fine without errors, e.g.:

Listening daemon: PID: 16013
MaxQueue set to: 150
No stats for Database check - forcing reload
Reading databases from /usr/local/share/clamav
Database correctly reloaded (966822 signatures)
SelfCheck: Database status OK.
