Installing CentOS 6 - part 3 - Chrome installation

To install chrome in CentOS 6 it is easier to just add Google's chrome repositories to yum and install from there.

1. I first installed a yum extender, a yum frontend to make things easier from XFCE.

yum install yumex

2. Then added the following google repository. Create the file /etc/yum.repos.d/google-chrome.repo with the following contents:

[google-chrome]

name=google-chrome

baseurl=http://dl.google.com/linux/chrome/rpm/stable/i386

enabled=1

gpgcheck=1

3. Import the public key:

rpm --import https://dl-ssl.google.com/linux/linux_signing_key.pub

4. Install google chrome from yumex or yum directly

yum install google-chrome-stable

Next post will be about how to install and configure remote desktop with vnc.

Installing CentOS 6 - part2

Continuing from previous post...

6. Enable XFCE as the default desktop environment can't be done without you to first installing the X Window System and gdm

yum groupinstall "X Window System"
yum install gdm

7. Set XFCE as default desktop environment by creating the file /etc/sysconfig/desktop


DESKTOP="XFCE"
DISPLAYMANAGER="GDM"


and editing /etc/X11/xinit/XClients so it accepts the option "XFCE"


GSESSION="$(which gnome-session 2>/dev/null)"
STARTKDE="$(which startkde 2>/dev/null)"
STARTXFCE="$(which startxfce4 2>/dev/null)"


# check to see if the user has a preferred desktop
PREFERRED=
if [ -f /etc/sysconfig/desktop ]; then
    . /etc/sysconfig/desktop
    if [ "$DESKTOP" = "GNOME" ]; then
PREFERRED="$GSESSION"
    elif [ "$DESKTOP" = "KDE" ]; then
PREFERRED="$STARTKDE"
    elif [ "$DESKTOP" = "XFCE" ]; then
PREFERRED="$STARTXFCE"
    fi
fi


if [ -n "$PREFERRED" ]; then
    exec "$PREFERRED"
fi


# now if we can reach here, either no desktop file was present,
# or the desktop requested is not installed.


if [ -n "$GSESSION" ]; then
    # by default, we run GNOME.
    exec "$GSESSION"
elif [ -n "$STARTKDE" ]; then
    # if GNOME isn't installed, try KDE.
    exec "$STARTKDE"
elif [ -n "$STARTXFCE" ]; then
    # if GNOME and KDE aren't installed, try XFCE
    exec "$STARTXFCE"
fi


# We should also support /etc/X11/xinit/Xclients.d scripts
XCLIENTS_D=/etc/X11/xinit/Xclients.d
if [ -d "$XCLIENTS_D" -a "$#" -eq 1 -a -x "$XCLIENTS_D/Xclients.$1.sh" ]; then
    exec -l $SHELL -c "$SSH_AGENT $XCLIENTS_D/Xclients.$1.sh"
fi


# Failsafe.


# these files are left sitting around by TheNextLevel.
rm -f $HOME/Xrootenv.0


# Argh! Nothing good is installed. Fall back to twm
{
    # gosh, neither fvwm95 nor fvwm2 is available; 
    # fall back to failsafe settings
    [ -x /usr/bin/xsetroot ] && /usr/bin/xsetroot -solid '#222E45'


    if [ -x /usr/bin/xclock ] ; then
/usr/bin/xclock -geometry 100x100-5+5 &
    elif [ -x /usr/bin/xclock ] ; then
/usr/bin/xclock -geometry 100x100-5+5 &
    fi
    if [ -x /usr/bin/xterm ] ; then
        /usr/bin/xterm -geometry 80x50-50+150 &
    fi
    if [ -x /usr/bin/firefox -a -f /usr/share/doc/HTML/index.html ]; then
/usr/bin/firefox /usr/share/doc/HTML/index.html &
    fi
    if [ -x /usr/bin/twm ] ; then
exec /usr/bin/twm
    fi
}

8. Finally change the runlevel from 3 to 5 in /etc/inittab

# inittab is only used by upstart for the default runlevel.

#

# ADDING OTHER CONFIGURATION HERE WILL HAVE NO EFFECT ON YOUR SYSTEM.

#

# System initialization is started by /etc/init/rcS.conf

#

# Individual runlevels are started by /etc/init/rc.conf

#

# Ctrl-Alt-Delete is handled by /etc/init/control-alt-delete.conf

#

# Terminal gettys are handled by /etc/init/tty.conf and /etc/init/serial.conf,

# with configuration in /etc/sysconfig/init.

#

# For information on how to write upstart event handlers, or how

# upstart works, see init(5), init(8), and initctl(8).

#

# Default runlevel. The runlevels used are:

#   0 - halt (Do NOT set initdefault to this)

#   1 - Single user mode

#   2 - Multiuser, without NFS (The same as 3, if you do not have networking)

#   3 - Full multiuser mode

#   4 - unused

#   5 - X11

#   6 - reboot (Do NOT set initdefault to this)

I wrote this post from google chrome installed on CentOS 6, I will explain how I installed it in the next post.

Installing CentOS 6 - part1

I managed to get a server from e-waste and I'm trying to setup a virtual-box kind of server so I can run some virtual machines.

Its spec is very tight with just 2GB of RAM to spare so I have chosen to use XFCE as the desktop environment.
I going to keep track of what I do in this post and the following ones.

1. Downloaded latest version CentOS 6.2 from a UK mirror:

http://www.centos.org/modules/tinycontent/index.php?id=34

I chose the minimal install ISO so I can go step by step and just have the bare minimum software needed for virtualbox to run smooth.

I burned the ISO and run through the installed just selecting the option to wipe out the whole disk, I'm not interested in disk partitioning this time around.

2. Configured network:

a) Edited the network script for eth0 so it uses dhcp

vi /etc/sysconfig/netowrk-scripts/ifcfg-eth0

Added the following lines so eth0 is enabled at boot and it uses dhcp client to get IP address:

ONBOOT="yes"

BOOTPROTO="dhcp"

b) Restarted the network service

/etc/init.d/network restart

3. Installed some additional packages

yum groupinstall base

4. Installed XFCE thanks to the epel extra yum repositories
 http://www.cyberciti.biz/faq/fedora-sl-centos-redhat6-enable-epel-repo/

a) Got the yum repository updated thanks to this RPM package:
epel-release-6-6.noarch.rpm

That was the last version of the package I found available in the following web site so I had to modify a bit the instructions.
http://mirror01.th.ifl.net/epel/6/i386/repoview/epel-release.html

wget http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-6.noarch.rpm
rpm -ivh epel-release-6-6.noarch.rpm

b) Installed the group package xfce

yum groupinstall xfce

I'll setup X and set XFCE as default desktop environment tomorrow...

Android - How to Download and Save Gmail Attachments on the Memory Card

I realised this morning that you can't download attachments to the SD card in Android 2.2 from the Gmail App (version 2.3.2 at the time I wrote this). I couldn't believe it at first but after googling a bit became clear that I am not the only one that experienced this issue.

Best solution I found online is the following:

1. Install ASTRO File Manager from the App Market
2. Go into Preferences of this app and tick the config parameter "Enable Browser Download"
3. After you do that, every time you press the preview button for the attachment in the Gmail App you will get prompted if you want to open it with ASTRO file download which will allow you to save it in the /sdcard/download folder with the name you wish.

Open .ics calendar events from thunderbird

I just found out today that if you add the lightning calendar addon to thunderbird it starts understanding calendar invites you receive from outlook. You get an attachment in the email called meeting.ics that you can then open with Outlook.

It is very convenient as I still think that thunderbird is the best email client but lightning is very poor as calendar application. I can still use outlook and exchange capabilities while using thunderbird for email. Great!

This is what you get as message after doing that:


You don't have to Accept the meeting with thunderbird, ignore that part and just open the .ics file with outlook and do the Accept-Decline thing there.

Always Packeteros!!!

Ara que la lliga de futbol de la Salle ha acabat per als Packeteros (equip oficial dels telemàtics jeje) podem fer balanç de la temporada.

Ha sigut una temporada atípica on molts dels integrants inicials del equip han sigut fitxats per treballar a diferents empreses de la talla d'HP, Cisco o Unitronics cosa que prova l'alt nivell de l'equip (no hem se el nom de l'empresa Alexis ho sento :P).

Varem començar amb dubtes però al final, gracies a l'esforç varem aconseguir quedar primers de grup en la segona fase i passar a les eliminatòries.

A 16ens de final ens han eliminat però queda un bon sabor de boca ja que molts hem participat en l'equip i en alguns moments el joc i les victòries in extremis van ser brillants.

Aquí tenim una foto d'alguns dels integrants de l'equip tot just en l'últim partit abans de les eliminatòries.














I aquí los fichajes de última hora je.















Esperem que l'any que ve els Packeteros retornin i facin encara més bon paper.

Una tarda al labtel
