Linux

I am using Ubuntu 7.10 Gutsy and GeForce with Nvidia as graphic card chipset. Until yesterday I can't change my screen resolutions, default is 1024 x 768 and its a maximal resolution. I am usually set the screen resolutions to 1280 x 960 when I am in Windows XP. Then one of my friend told me try to use this command in order to increase my screen resolutions.

k4tz@k4tz-desktop:~$ sudo
dpkg-reconfigure -phigh xserver-xorg

Password:

Yesterday my SSL web certificate was expired and I have to generate it again. Last year I am only generate it for 1 year. More information you can visit this link.

For information :

My SSL Apache file are in this directory :

 /etc/apache2/ssl-sites-available/example.com.ssl

 /etc/apache2/ssl-sites-enabled/example.com.ssl

example.com.ssl configuration :

SSLEngine on
SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL
SSLCertificateFile /etc/apache2/ssl/server.crt       
SSLCertificateKeyFile /etc/apache2/ssl/server.key

Now, let's generate :

It's been 2 months I am using Sierra 3G PCMCIA modem in  Windows XP. Installation in Windows XP is quite easy, that's why for 2 months I am enjoying using it.

I dont know why this morning I had in mind how to install 3G modem in Ubuntu box. And I remember in installation CD, the seller also providing linux driver but there are no instruction how to install it :(. Yes, I think I have to install it myself.

I am using Ubuntu Gutsy and use the driver for Linux that included in installation CD.

Sierra provide driver for Linux, you can download Linux driver ini this page:

Installation

I thought Google earth is only for Windows user, but I am wrong. We can also run Google earth in Linux. Just like my other article, Google earth installation in Ubuntu is quite simple. Same as Skype, Google earth also not included in any Ubuntu repository. We have to use medibuntu repository.

Installation

We have to  add medibuntu repository in order to have Google earth installed.
I am using Ubuntu 7.10 Gutsy with amd64 machine. Other Ubuntu
distribution can use the list from here.

Not understanding about file permissions in Linux ? I'll give a simple explanation about that and hopefully it will be usefull.

Permissions
in Linux can be read=r, write=w and execute=x. There
are 3 categories of ownership for each file and directory:

Ubuntu, salah satu distro Linux yang cukup populer dan menempati urutan pertama terbanyak penggunanya di dunia menurut distrowatch.com. Langkah-langkah instalasi ubuntu dapat didownload disini.

If we have create one execution file, for example  in /usr/local/bin/mirror . Can we put this file as init script file and always run while startup and everytime our linux system will check it ??? Off course we can use cron to make it a routine execution file, but I will use other way.

Here are my experience when I am trying to have an init script :

First chmod 755 /usr/local/bin/mirror :

jafar@dns:$ sudo chmod 755 /usr/local/bin/mirror

jafar@dns:$ sudo vi /etc/init.d/mirror

#! /bin/sh

/usr/local/bin/mirror >/dev/null 2>&1 &
