Ubuntu - Tweak Firefox for speed and SSD disk

Ubuntu

Firefox is a very powerfull and versatile browser, but it has the tendancy of doing a huge amount of disk write accesses.

If you hold a modern computer with very fast hard disk, it's no problem.

But if your hard disk is slow or if it is a SSD drive, you then need to minimize to a maximum all the disk write access, in term of responsivness and durability.

This article will explain how to optimize firefox following two main directions :

  • minimize the write accesses (very interesting for SSD drives)
  • tweak generic parameters for performance boost

Its first effect will be a huge disk write access reduction and ... a real boost in terms of performance !

So lets start to tweak your firefox parameters to rediscover your surf experience.

Ubuntu - HP Laserjet Multifunction Scan-to-Folder

Ubuntu

hp-cm1312-mfpHP Multi-Function Network Printers support is very good under Linux thanks to HP Linux Imaging and Printing (HPLIP).

But one important functionality is still missing : Scan-to-folder.

In fact, under Linux, you can scan documents easily, but you need to do it thru a graphical interface like XSane or Simple Scan.

Natively, there is no possibility to control the scanning in a scan-to-folder way.

This article will analyse the HP interfaces available and will explain how to setup a shell script to do :

  • a one-click scan interface, that will immediately scan current document straight in a default folder
  • a scan server, that will wait for you to press the Start Scan button from the scanner to scan current document in a default folder

This script will allow you to setup default document folder & format (jpg, png, pdf, ...). It will handle documents from the scanner Glass Window and from Auto Document Feed tray.

It has been tested on an HP MFP 1312, but it should be compatible with many modern HP multi-function network printer.

Ubuntu - Configure Wifi connexion thru Command line Tools

dropcap-ubuntu-wifi

Nowaday, interface like Network manager makes wifi connexion setup a very simple task.

But in some specific cases (ubuntu server, ubuntu minimal media center, ...), you may need to setup you WEP or WPA wifi connexion directly from command line, without using network manager.

This article explains how to fully configure a WEP or WPA encrypted wifi network from a console terminal, using only command line tools.

It has been tested on Ubuntu Precise 12.04, but it should work on any modern Ubuntu or Debian flavored distro.

Ubuntu - Boot failure ending with initramfs prompt

Ubuntu

Yesterday was a fearful day ... when I switched on my laptop, it was totally stuck during the boot process, leaving me with a scary initramfs prompt.

Obviously, this has happened just after I had finished mounting 3 hours of video with OpenShot Video Editor and unloaded almost 100 pix from my digital camera !

I was able to get the grub menu, but whatever kernel version I was selecting, I was always ending up with the following screen :

mount: mounting /dev on /root/dev failed: No such file or directory
mount: mounting /proc on /root/proc failed: No such file or directory
Target filesystem doesn't have /sbin/init.
No init found. Try passing init=bootarg.

BusyBox v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4) built-in shell (ash)
Enter 'help' for a list of built-in commands.
(initramfs)

I first though that my hard disk had died. But after a second though, as I was getting grub menu and ending on a initramfs prompt, the boot sector has been read properly. So hard disk was not in a completely pathetic condition.

In fact, the problem was coming from a corruption of my root filesystem. Because of that corruption, the root filesystem couldn't be mounted at boot.

This short article explains how to recover from such a scary situation and how to get your computer back to a working condition.

Even if tested on Ubuntu, it should be applicable to any Linux based computer with a ext3 or ext4 root filesystem.

Ubuntu - Automount Nexus 7 in MTP mode

dropcap-ubuntu-android

Latest Android devices, like Nexus 7, are using 2 different USB connexion modes : PTP and MTP.

With PTP mode, the tablet is seen as a digital camera. This is working Out Of The Box under Ubuntu 12.04. But, you can only access DCIM directory of your device.

With MTP mode, the tablet is seen as a multimedia device where you can access the complete exported filesystem. But it doesn't work Out Of The Box under Ubuntu 12.04. It needs some setup and configuration to work.

Even if you can access easily a MTP device thru a program called gmtp, it is not as convenient as a conventional USB mass storage, accessible directly from Nautilus.

This guide explains how to configure your Ubuntu computer to directly access your Nexus 7 exported filesystem in MTP mode as soon as you plug it to a USB port.

Thanks to some udev rules, your Nexus 7 will automatically mount when device is plugged in & unmount when device is unplugged.

This guide has been done for Google Nexus 7, but it should work with any other MTP device (Android phone or tablet, MP4 player, ...) if you adapt the Udev rules according to your device.
I've got some feedback that it has already been adapted succesfully to Samsung Galaxy S2, Galaxy S3, Motorola Atrix HD & Google Nexus 4.

It has been done under Ubuntu 12.04, but has also been tested succesfully under Ubuntu 12.10.

Ubuntu - Automount network share with autofs

Ubuntu

It is more & more common to have a NAS or server at home, where you keep all the files that you need to share between your home computers or appliances. For example, if you want to share your music or video library across different computers, you will mostly need to share them thru a cifs (samba) share.

This article will explain how to setup a Ubuntu workstation to automount a list of network shares. These network shares won't be mounted all the time, they will be mounted "on demand", when you need them. They will be available thru a desktop icon.

The main advantage of automount approach is to have these network shares accessible thru the normal filesystem. This way, even applications which are not able to use gnomefs will be able to access files on the network shares.

This setup has been done on a Ubuntu Jaunty 9.04 workstation, but it should work on any later version.

Debian 7 - Installation on Sony VAIO VGN-TX2XP

dropcap-vaio-tx2xp

Sony Vaio VGN-TX2XP is a 7 years old, 1.25kg and 11.1'' screen notebook. When it has hit the market, it was a very high end laptop. It has been designed by Sony for durability as it is fully made of carbon, based on a multi-layered carbon fiber and carbon composite.

With an Intel Pentium M 1.2GHz CPU, 1 Gb RAM, an Intel 915GM chipset and a 16:9 1366×768 screen, it was originally delivered with Windows XP. Even if it was quite responsive in its childhood, it has become incredibly slugish years after years.

This laptop being very robust, very light weight and having a heavy duty battery, it was worth giving it a new life.

As it integrates some very standard components, I decided to install latest stable Debian 7.

This article explains the few steps needed to get a fully operational Vaio VGN-TX2XP running Debian Wheezy 7.0.

Thanks to Debian 7, you'll get a brand new Vaio VGN-TX2XP, giving back its full speed and reactivity under latest Gnome 3.4 environment.

Debian - Very fast backup server for your Windows PC

Debian

Till today, a lot of personal computers are still running Windows OS (XP, Visat, Seven, ...) and many people are still keeping a lot of valuable datas directly on their workstation or laptop hard disk. Most people do so because of ignorance of the risks  or because they are always on the move and they need their files available anytime, even not connected to any server.

The side effect of this behaviour is that everything can be lost in case of a hard disk crash, as all the datas are stored locally on the PC.

So, to avoid that type of loss, it is very important to save all your personal valuable files on a secure server.

RSync may be the clue to this problem. In fact, RSync is widely used to do data backup in the Unix/Linux world and it is having a lot of advantages :

  • it is multi-os (unix, linux, windows, ...)
  • it is using differential backup mecanism (only modifications are sent across the network)
  • it is command line base
  • some GUI are available, even on Windows (DeltaCopy)

This article will explain how to provide a very simple and very efficient way to backup your Windows PC local files on a Debian server with the help of RSync and DeltaCopy.

It has been succesfully tested on Windows XP and Windows Seven clients and on Debian Squeeze server.

By following these steps, you will be able to save all your local datas from your Windows PC to your Debian server in a very optimised and lightning fast way. Whatever happens to your PC, your personnal data will be safe !

Debian - Tune Apache/PHP/MySQL for a Compact Flash disk

Debian

After having tuned your Debian server according to the article Install Debian on a server with a Compact Flash main disk, you plan to use it as a LAMP web server.

Once you have installed all the Apache, Php & MySQL packages with aptitude, you then need to do some specific tuning on these packages configuration as your server is running on Compact Flash.

This article describes all the ajustments I've done on my server to setup :

  • Apache to deal with /var/log on tmpfs
  • PHP to save sessions on tmpfs
  • MySQL to fully load the database in memory (small one)

This setup is specific to my needs and has been done to minimize the disk access to the CF.

Debian - Share same port for HTTPS, SSH and OpenVPN

Debian

If you need to administrate your home network while on the move, you will soon realize that you need different type of accesses.

The standard accesses you may need are :

  • Https to access your secured pages or webdav shares
  • SSH to administrate your main server
  • OpenVPN to get a full unrestricted access to your LAN

The only problem is that many Internet providers are blocking most of the ports used by these protocols. With some very restrictive providers (or with some corporate proxy) the only available ports may be 80 & 443.

So the solution to that problem is to allow Https, SSH & OpenVPN to share the same 443 port. With such setting, all your connexions needs can be handled from any type of network.

To help us to reach that goal, a fantastic little tool is available under Linux : sslh.

This tool listens on one specific port, analyse the stream & forward it to a specific local port according to thits type. To be able to handle any type of SSH client and OpenVPN connection, we need to install and configure the latest version of SSLH (1.9 minimum).

This guide will explain how to install the latest version of sslh, which is not available in the distribution repository, on a Debian Squeeze. It should also work on Debian Lenny and on some flavours of Ubuntu also.
