Site Description:
andLinux is a complete Ubuntu Linux system running seamlessly in Windows 2000 based systems (2000, XP, 2003, Vista; 32-bit versions only). This project was started for Dynamism for the GP2X community, but its userbase far exceeds its original design.

andLinux uses CoLinux as its core which is confusing for many people. CoLinux is a port of the Linux kernel to Windows. Although this technology is a bit like running Linux in a virtual machine, CoLinux differs itself by being more of a merger of Windows and the Linux kernel and not an emulated PC, making it more efficient. Xming is used as X server and PulseAudio as sound server.

andLinux is not just for development and runs almost all Linux applications without modification.

Basicly this howto explain how to configure ppp using a Windows 2000 desktop.

This HOWTO describes how to run remote X applications. How to have an X program display on a different computer than the one it's running on. How to make an X program run on a different computer than the one you're sitting at. The focus of this HOWTO is on security and this HOWTO also contains information on running X applications locally, but with a different user-id, and information on setting up a computer as an X terminal.

If you are running Chkrootkit on a cPanel server, or other it may be a false positive because Chkrootkit only checks the port 465 that should be used to secure smtp.

All the people who works daily on a computer need to have a work space. Some time is very interesting how people organise their objects.

I you are reding this, probably you are getting the next error:

error: 'Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)'
Check that mysqld is running and that the socket: '/tmp/mysql.sock' exists

To fix it, and if you are running cPanel just try to run the next commands:

# ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock

# /scripts/mysqlup --force

If you have a cgi or php script that you want to make available to all users on your server, you just need to add an Alias in

"With the latest release of VirtualBox, Windows and Linux can be run together simultaneously, and you don't even need to switch between the two. Using the seamless Windows feature of VirtualBox, you can run two different operating systems simultaneously on a single PC and you can use the applications of both operating systems from the same desktop simultaneously.

This has been made possible by the combined efforts of VirtualBox and SeamlessRDP that is meant for seamless Windows support for rdesktop. The rdesktop, ie, the remote desktop feature helps in creating X11 Window for each Windows application that you will run from the host machine, further the application that is running can be moved and resized."

"Prerequisites
Before we proceed, you should have the latest VirtualBox 1.5.2 installed on your system. For this download VirtualBox 1.5.2 rpm for openSUSE 10.3 from the link provided in the direct hit box. For installation first navigate to the folder where you have downloaded the rpm file and then run the following commands in the terminal.

# rpm -ivh VirtualBox-1.5.2_25433 _openSUSE103-1.i586.rpm

# /etc/init.d/vboxdrv setup


For running VirtualBox, navigate to Computer > more application and on the new application section click on the 'Innotek VirtualBox' icon."

Some recent operating systems have their main memory divided into pages and it allows better utilization of memory.

Kernel swap and allocates memory using pages.

How to change default vsftpd port (TCP port 21)?

vsftpd (Very Secute FTP Daemon) is used by Fedora, Ubuntu, RHEL and other Linux based distros.

Changing default can be a good ideia for security reasons.

Login to your server as root

Open vsftpd.conf file (by default /etc/vsftp/vsftpd.conf or /etc/vsftpd.conf)
# nano vsftpd.conf

Find line that read as follows
listen_port=21

Then, replace port 21 with new port (example 23)
listen_port=231

Save and Exite. Make sure that no other service is usign that port.

Restart vsftpd
# /etc/init.d/vsftpd restart

The pw command allow root to add, modify and remove users and groups.

Example:
Adding an user usign add:
# pw useradd -n usern_you_want -s /bin/csh -m
# passwd user_you_want

The optins '-s' and '-m' (s -> Set shell /bin/csh) (-m -> setup home directory /home/user_you_want)

Delete a user usign pw:
# pw userdel -n user_you_want -r

'r' is used to remove the home directory created and all the content.
Note that -r option remove home directory & its contents.

Use help:
# pw useradd help
# man pw

Is very easy to change root password on Linux / BSD / Unix systems on propmpt line (shell) using a few commands.

Log in to your server as root

If you are setting mysql root password first time you can use:

Usign mysqladmin
1st way:
# mysqladmin password “password_you_want“

2nd way:
# mysqladmin -u root password “Npassword_you_want“

3rd way:
# mysqladmin -u root -h localhost password “password_you_want“

Use the same way if you want to change the current password:
# mysqladmin -u root password "password_you_want"

Use: Start -> Run
"cmd"

Then execute on msdos prompt:

C:\>ipconfig /all

Or follow this steps:

1) Click on Start button > Settings > Network connections
2) Double click on Local Area Connection
3) Click on Properties button
4) Select Internet Protocol (TCP/IP)
5) Click on Properties button and Look for Preferred DNS Server:

You can simply use that commands to find your DNS servers on a Linux/Unix/BSD based OS:or usign:

# nano /etc/resolv.conf

# less /etc/resolv.conf

If you want to upgrade a machine running Fedora from 32.bit to 64-bit first read this article:

Upgrade from 32-bit to 64-bit Fedora Linux without a system reinstall

"One great thing about Linux is that you can transplant a hard disk from a machine that runs a 32-bit AMD XP processor into a new 64-bit Intel Core 2 machine, and the Linux installation will continue to work. However, if you do this, you'll be running a 32-bit kernel, a C library, and a complete system install on a processor that could happily run 64-bit code. You'll waste even more resources if your new machine has 4GB or more of system memory, and you'll be forced to either not use some of it or run a 32-bit Physical Address Extension (PAE) kernel. Cross-grading to the 64-bit variant of your Linux distribution can help you use your resources more wisely."
