Hello everybody, now a days people use router for wifi connections, sharing more than 2 computers. Every router comes with its firmware. But what is firmware ?

In electronics and computing, firmware is a term often used to denote the fixed, usually rather small, programs and/or data structures that internally control various electronic devices.

People use different firmwares to make router more powerful. One of the famous firmware is DD-WRT.

DD-WRT is a Linux based alternative OpenSource firmware suitable for a great variety of WLAN routers and embedded systems. The main emphasis lies on providing the easiest possible handling while at the same time supporting a great number of functionalities within the framework of the respective hardware platform used.

DD-WRT is a Linux-based firmware for several wireless routers, most notably the Linksys WRT54G (including the WRT54GL and WRT54GS). Like other similar projects, DD-WRT is considered a third-party firmware solution designed to replace the firmware that ships pre-installed on many commercial routers. This is done for a variety of reasons; including but not limited to the addition of features which are not typically included in a manufacturer’s router firmware.

DD-WRT includes such features as support for the Kai network, daemon-based services, IPv6, Wireless Distribution System, RADIUS, advanced quality of service, radio output power control, overclocking capability, and software support for a Secure Digital Card hardware modification.

Watch the following video before installing DD-WRT on your Router

How to Compile Linux kernel 2.6
Start…

Compiling custom kernel has its own advantages and disadvantages. However, new Linux user / admin find it difficult to compile Linux kernel. Compiling kernel needs to understand few things and then just type couple of commands. This step by step howto covers compiling Linux kernel version 2.6.xx under Debian GNU Linux. However, instructions remains the same for any other distribution except for apt-get command.

Step # 1 Get Latest Linux kernel code

Visit http://kernel.org/ and download the latest source code. File name would be linux-x.y.z.tar.bz2, where x.y.z is actual version number. For example file Linux-2.6.25.tar.bz2 represents 2.6.25 kernel version. Use wget command to download kernel source code:
$ cd /tmp
$ wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-x.y.z.tar.bz2

Note: Replace x.y.z with actual version number.

Step # 2 Extract tar (.tar.bz3) file

Type the following command:
# tar -xjvf linux-2.6.25.tar.bz2 -C /usr/src
# cd /usr/src

Step # 3 Configure kernel

Before you configure kernel make sure you have development tools (gcc compilers and related tools) are installed on your system. If gcc compiler and tools are not installed then use apt-get command under Debian Linux to install development tools.
# apt-get install gcc

Now you can start kernel configuration by typing any one of the command:

* $ make menuconfig – Text based color menus, radiolists & dialogs. This option also useful on remote server if you wanna compile kernel remotely.
* $ make xconfig – X windows (Qt) based configuration tool, works best under KDE desktop
* $ make gconfig – X windows (Gtk) based configuration tool, works best under Gnome Dekstop.

For example make menuconfig command launches following screen:
$ make menuconfig

You have to select different options as per your need. Each configuration option has HELP button associated with it so select help button to get help.

Step # 4 Compile kernel

Start compiling to create a compressed kernel image, enter:
$ make
Start compiling to kernel modules:
$ make modules

Install kernel modules (become a root user, use su command):
$ su -
# make modules_install

Step # 5 Install kernel

So far we have compiled kernel and installed kernel modules. It is time to install kernel itself.
# make install

It will install three files into /boot directory as well as modification to your kernel grub configuration file:

* System.map-2.6.25
* config-2.6.25
* vmlinuz-2.6.25

Step # 6: Create an initrd image

Type the following command at a shell prompt:
# cd /boot
# mkinitrd -o initrd.img-2.6.25 2.6.25

initrd images contains device driver which needed to load rest of the operating system later on. Not all computer requires initrd, but it is safe to create one.

Step # 7 Modify Grub configuration file – /boot/grub/menu.lst

Open file using vi:
# vi /boot/grub/menu.lst

title Debian GNU/Linux, kernel 2.6.25 Default
root (hd0,0)
kernel /boot/vmlinuz root=/dev/hdb1 ro
initrd /boot/initrd.img-2.6.25
savedefault
boot

Remember to setup correct root=/dev/hdXX device. Save and close the file. If you think editing and writing all lines by hand is too much for you, try out update-grub command to update the lines for each kernel in /boot/grub/menu.lst file. Just type the command:
# update-grub
Neat. Huh?

Step # 8 : Reboot computer and boot into your new kernel

Just issue reboot command:
# reboot

Q. How do I install webmin control panel for my FreeBSD server?

A. Webmin is a web-based interface for system administration for Unix including FreeBSD. Using any browser that supports tables and forms, you can setup user accounts, Apache, DNS, file sharing, firewall and so on. Webmin consists of a simple web server, and a number of CGI programs which directly update system files like /etc/inetd.conf and /etc/master.passwd.
Install webmin

To install webmin, update your ports, enter:

# portsnap fetch update

Install webmin from /usr/ports/sysutils/webmin, enter:

# cd /usr/ports/sysutils/webmin
# make install clean
Configure webmin

Now, webmin is installed. Start webmin on startup, enter:

# vi /etc/rc.conf
Append following line:
webmin_enable=”YES”

Save and close the file. You need to run /usr/local/lib/webmin/setup.sh script in order to setup the various config files, enter:

# /usr/local/lib/webmin/setup.sh

Sample output:

***********************************************************************
* Welcome to the Webmin setup script, version 1.420 *
***********************************************************************
Webmin is a web-based interface that allows Unix-like operating
systems and common Unix services to be easily administered.

Installing Webmin in /usr/local/lib/webmin …

***********************************************************************
Webmin uses separate directories for configuration files and log files.
Unless you want to run multiple versions of Webmin at the same time
you can just accept the defaults.

Log file directory [/var/log/webmin]: [Press Enter]

***********************************************************************
Webmin is written entirely in Perl. Please enter the full path to the
Perl 5 interpreter on your system.

Full path to perl (default /usr/bin/perl): [Press Enter]

Testing Perl …
Perl seems to be installed ok

***********************************************************************
Operating system name: FreeBSD
Operating system version: 7.0

***********************************************************************
Webmin uses its own password protected web server to provide access
to the administration programs. The setup script needs to know :
– What port to run the web server on. There must not be another
web server already using this port.
– The login name required to access the web server.
– The password required to access the web server.
– If the webserver should use SSL (if your system supports it).
– Whether to start webmin at boot time.

Web server port (default 10000): [Press Enter]
Login name (default admin): [Press Enter]
Login password: [type password]
Password again:
Use SSL (y/n): y
