Como cambiar la configuracion regional de Linux Centos desde linea de comandos

Para realizar un cambio efectivo sin utilizacion de interfaz grafica en Linux Centos 5.3 realizar lo siguiente:

primer paso, comprobar que configuraciòn se tiene actualmente, con el comando locale escrito en una consola nos muestra la configuracion por ejemplo la mia tiene la siguiente:

LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=


para lograr dicha configuracion hay que editar el archivo siguiente con algun editor, yo lo hice con el editor nano

nano /etc/sysconfig/i18n

y puse las siguientes lineas en tal archivo

LANG="en_US.UTF-8"
SUPPORTED="en_US.UTF-8:en_US:en"
SYSFONT="latarcyrheb-sun16"


reinicie mi computadora y listo

Montar ntfs en centos 5.3

NTFS support in CentOS 5.3
April 11, 2009 by Resa
Filed under: Centos, Linux

After my experiences with the installation of msttcorefonts and conky I am starting to get used that installation of certain packages and/or software requires a bit more effort in CentOS. Today I popped in an NTFS formatted USB stick only to get the message that it could not be mounted since NTFS is not supported.

In the (Debian) based distributions I used so far that was resolved by installing ntfs-3g packages and that was it. However, a search through the packages showed no packages available with ntfs in the name and/or description.

So — as usual — I Googled and found the following page in the CentOS wiki: How to mount an NTFS filesystem. The first thing that was indicated is that I should enable the rpmforge repository. Therefore it was suggested to have a look at the page: Installing rpmforge. This page contains clear instructions, summarized the following is required.

First the priorities package needs to be installed. It can be used to enforce ordered protection of repositories, by associating priorities to repositories. It can be installed as root or — as I do — while acting as root.

sudo yum install yum-priorities

After this is installed it has to be confirmed that the /etc/yum/pluginconf.d/priorities.conf file contains the following lines:

[main]
enabled=1

I checked this by opening this file with nano and acting as root with the command:

sudo nano /etc/yum/pluginconf.d/priorities.conf

I did not have to edit the file since the required lines where all installed. Next the /etc/yum.repos.d/.repo file needs to be edited so that the priorities are set. In my case the content is as follows:

[base],[addons],[updates],[extras] ... priority=1
[centosplus],[contrib] ... priority=2
rpmforge ... priority=99

Now that this is done the PGP key for the repo has to be installed, this can be done with the following command:

rpm --import http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt

Now you have to download the rpmforge release package that is required for your architecture, therefor download either one of the following:

* i386
* x86_64

For my installation I required the i386 version, so I downloaded it and checked the package with the command:

rpm -K rpmforge-release-0.3.6-1.el5.rf.*.rpm

It checked out okay so I installed it with the following command:

sudo rpm -i rpmforge-release-0.3.6-1.el5.rf.*.rpm

After installation I could continue with the installation for NTFS support and as instructed installed the following packages:

yum install fuse fuse-ntfs-3g dkms dkms-fuse

However …. , even after a reboot, I still received the same error when I plugged in the USB stick. So I started up the package manager and searched (again) for ntfs. From the list of packages found I decided to install the following packages:

* dkms-ntfs-2.1.27-2.nodist.rf.noarch
* findntfs-1.3-1.el5.rf.i386
* gnome-vfs2-ntfs-1.13.1-1.el5.rf.i386
* ntfsprogs-1.13.1-1.el5.rf.i386

Which of these packages really solved the issue — my guess is the dkms package — I am not entirely certain, but now my USB stick is recognized and I can browse all directories and files.
