How to Setup a Wireless Ubuntu Router

noreply@blogger.com (Anonymous) — Fri, 16 Jul 2010 09:48:00 +0000

I hope this helps others and gives hobbyists a fun project.
Here's the hardware used:
Celeron based PC (755MHz)
512MB RAM
10GB ATA HDD
Realtek 10/100 NIC (2 of them)
There is an integrated NIC on the motherboard, but I couldn't find any drivers that worked.
AtlantisLand I-Fly A02WP54G (which I borrowed from another PC).
A Basic Server Install:
First thing you'll need to complete is a base server install on the PC (don't use LAMP or DNS). From googling, I found out that the wireless card I'm using will work from Ubuntu versions 5.10 (Breezy) and newer.
After the installation of the server is complete, make sure that you configure your repositories to use "Universe".

Edit this file: /etc/apt/sources.list
sudo nano -w /etc/apt/sources.list
And add this: universe
The lines you edit, will look something like this:
deb http://ca.archive.ubuntu.com/ubuntu/ edgy main restricted
deb-src http://ca.archive.ubuntu.com/ubuntu/ edgy main restricted
Make sure you create a backup copy of this file BEFORE you do anything. I should also note that when examining your sources.list, if you see an entry for CD,remove it. (For people interested in enhancing their repositories, please see here: http://ubuntulinuxhelp.com/the-best-ubuntu-linux-repository-list/)
After editing the sources.list file, use this command to update, so that you will receive the most recent versions of updates as we complete the installation:
sudo apt-get update
The Network:
This PC needs to work like the broken router did. Therefore:
eth0 = (Which is on the motherboard) is not working, and I think it's a driver related issue.

eth1 = The external WAN connection to my ISP.
eth2 = Is the internal LAN connection to the network.
ath0 = Wireless connection.
br0 = The virtual bridge connecting eth2 (LAN) to ath0 (Wireless) - So that wireless connections can communicate on the network, which in turn can communicate with the Internet.
Adding the bridge is not too difficult. First we need to get the package like this:
sudo apt-get install bridge-utils
Now edit the network configuration file (interfaces) with this command (you don't have to use nano, you can use any text based editor):
sudo nano /etc/network/interfaces
Edit the open file like this:
(I have included notes in this code below, please make sure that you check them).
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
#The loopback network interface
auto lo
iface lo inet loopback
#etho is on the motherboard and the driver is not available? So... I had to disable this section.
#auto eth0
#iface eth0 inet dhcp
#pre-up iptables-restore < /etc/iptables.conf
#This is the WAN section. It connects to the Internet.
#Normally this uses DHCP from your ISP, so leave it as DHCP if your ISP uses DHCP.
#The "pre-up" command loads up the firewall iptables. Leave it enabled.
auto eth1
iface eth1 inet dhcp
pre-up iptables-restore < /etc/iptables.conf
#This is the Wireless section.
auto ath0
iface ath0 inet manual
wireless-mode master
#You must enter your own ESSID below - Change the word "nomadic" to your own ESSID.
wireless-essid nomadic
#This is the Bridge section. You don't have to use the 10.1.1.0, which is a proper private IP (LAN) network range, you can change it to your needs.
auto br0
iface br0 inet static
address 10.1.1.1
network 10.1.1.0
netmask 255.255.255.0
broadcast 10.1.1.255
bridge-ports eth2 ath0
Save the file and exit.
With regards to the "eth1" section, if your ISP does not use DHCP, then they can provide you with the correct information. That section should then be configured to look like this:
auto eth1
iface eth1 inet static
address 72.138.51.135
netmask 255.255.254.0
gateway 72.138.50.1
pre-up iptables-restore < /etc/iptables.conf
Note: DNS settings for the LAN (to be able to access web sites), is covered further down in the DHCP section.
Get WiFi Working:
The network card uses a madwifi driver and you can check here to see how to detect and install it: https://help.ubuntu.com/community/Router/Madwifi
I should point out that this resource helps to tell if your WiFi card is compatible: https://help.ubuntu.com/community/WifiDocs/WirelessCardsSupported but I don't think it is an exclusive list. You can also try here: http://ubuntulinuxhelp.com/ubuntu-hardware-compatability-list-hcl/
We need WAP in Master mode, from one of the help.Ubuntu.com links (above):
"If you are plan on using this wireless network adapter in "master" mode (i. e. for the purposes of setting up a wireless router)..."
So, let's do this to install the madwifi drivers:
wget http://umn.dl.sourceforge.net/sourceforge/madwifi/madwifi-0.9.3.1.tar.gz
tar -xvzf madwifi-0.9.3.1.tar.gz
cd madwifi-0.9.3.1
And this to install the tools + compile and install the needed module:
Just as the link said, we need to switch to master mode. We do this by creating the required file:
sudo nano /etc/modprobe.d/madwifi
And adding this code to the madwifi file:
options ath_pci autocreate=ap
Our wireless card is now in Master mode and we just have to load it by doing this:
sudo modprobe ath_pci
Time to move on...
The Firewall Needs to Forward Data:
We are setting up this firewall to simply forward data, not to protect the network! (Network protection is a whole other topic).
As with the WiFi section above, Ubuntu also has a great resource for that here: https://help.ubuntu.com/6.10/ubuntu/serverguide/C/firewall-configuration.html
And again, I am able to use their help in this guide.
Remember that eth0 is the WAN (Gateway) connection to the Internet, so (using the Ubuntu information), we need to do this:
sudo iptables -t nat -A POSTROUTING -s 10.1.1.0/24 -o eth1 -j MASQUERADE
sudo iptables -A FORWARD -s 10.1.1.0/24 -o eth1 -j ACCEPT
sudo iptables -A FORWARD -d 10.1.1.0/24 -m state --state ESTABLISHED,RELATED -i eth1 -j ACCEPT
Logging is a good idea. Logs should be found here:
/var/log/messages
/var/log/syslog
/var/log/kern.log.
And to enable the logging, use this code:
sudo iptables -A INPUT -m state --state NEW -p tcp --dport 80 -j LOG --log-prefix "NEW_HTTP_CONN: "
Remember when we entered this line "pre-up iptables-restore < /etc/iptables.conf" into the network setup? Let's make sure we save the file accordingly (so that this works):
sudo iptables-save > /etc/iptables.conf
We need the router to be able to forward data (packets) using IPv4 (which most everyone uses). You can edit this file:
sudo nano /etc/sysctl.conf
To change this line:
#net.ipv4.conf.default.forwarding=1
So that it looks like this:
net.ipv4.conf.forwarding=1
DHCP needs to run so PC's can connect easily.
Install DHCP:
sudo apt-get install dhcpd
Edit the configuration file for DHCP:
sudo nano /etc/dhcpd.conf
To look like this (your LAN based IP network address might be different, just make sure it matches what you set up in the "Network" section above):
(I use openDNS: http://www.opendns.com/)
#/etc/dhcpd.conf
default-lease-time 600;
max-lease-time 7200;
#Change the following to the DNS from your ISP or use openDNS
option domain-name-servers 208.67.222.222, 208.67.220.220;
#I don't need this but if I wanted an internal web server or something via FQDN...
option domain-name "nomad.int";
#Subnet for DHCP clients
subnet 10.1.1.0 netmask 255.255.255.0 {
#Range of 10 machines - If you need more, increase the range
range 10.1.1.20 10.1.1.29;
option subnet-mask 255.255.255.0;
option broadcast-address 10.1.1.255;
option routers 10.1.1.1;
}
DHCP failed to work properly, that's when I forgot that DHCP listens for address requests on the first physical NIC and I still need it to work with wireless (eth0 is dead). That means it needs to work with the virtual bridge connecting eth2 (LAN) to ath0 (Wireless) - So that wireless connections can communicate on the network, which in turn can communicate with the Internet. Edit the DCHP file:
sudo nano /etc/default/dhcp
And add the bridge:
INTERFACES="br0"
Everything should be done now.
After restarting - a cold restart get's the whole thing working - (I had to reboot and restart a few times before writing this - I made a few mistakes), everything should work.

Install Billing CCL (CafeConLenche) di Ubuntu 7.10 atau 8.04 Hardy

Pertama yang harus dilakukan adalah download CafeConLenche, ada 4 paket debian ke folder /home/”nama user”/
libccls_0.7.1-2_i386.deb (untuk diinstall di server)
cclfox_0.7.1-2_i386.deb (untuk diisntall di server)
libcclc_0.7.1-2_i386.deb (untuk diinstall di client)
cclcfox_0.7.1-2_i386.deb (untuk diinstall di client)
bisa didownload disini
sebelum menginstall billing harus menginstall library dibawah ini terlebih dahulu
sqlite3
glib2.0
libfox-1.6-0
openssl
memulai installasi
pertama buka terminal, lalu ketikan kode dibawah ini satu-persatu:
$ sudo apt-get install sqlite3 libsqlite3-dev
$ sudo apt-get install libfox-1.6-0
$ sudo apt-get install libglib2.0-dev
$ sudo apt-get install libssl-dev
$ sudo apt-get install libfox-1.6-0 (untuk ubuntu Hardy Heron)
setelah itu edit /etc/ld.so.conf, masih diterminal ketikan kode berikut
$ sudo gedit /etc/ld.so.conf
lalu copykan baris dibawah ini:
/usr/lib
/usr/local/lib
install billing server di server pastikan paket (libccls_0.7.1-2_i386.deb) dan (cclfox_0.7.1-2_i386.deb) sudah ada di folder /home/”nama user”/
masih diterminal ketikan kode berikut
$ sudo dpkg -i libccls_0.7.1-2_i386.deb
$ sudo dpkg -i cclfox_0.7.1-2_i386.deb
(atau kalau malas menginstall di terminal bisa di double click 2 paket diatas tersebut)
lalu jalankan Server Billing CCL dengan perintah:
install billing client di client dan pastikan jug paket (libcclc_0.7.1-2_i386.deb) dan (cclcfox_0.7.1-2_i386.deb) sudah ada di folder/home/”nama user”/
diterminal ketikan kode berikut:
$ sudo dpkg -i libcclc_0.7.1-2_i386.deb
$ sudo dpkg -i cclcfox_0.7.1-2_i386.deb
(atau kalau malas menginstall di terminal bisa di double click 2 paket diatas tersebut)
agar billing client langsung Lock Screen saat komputer dihidupkan.

Download certificate CA.pem dan cert.pem
buat folder di /home/”nama user”/.cclfox diserver dan di client copykan CA.pem dan cert.pem ke /home/”nama user”/.cclfox diserver dan di client.
untuk menjalankan billing di komputer server di terminal ketikan kode “cclfox” tanpa tanda kutip, dan untuk menjalankan billing komputer client ketikan kode “cclcfox -host (ip address server) -name ws1” tanpa tanda kutip
Agar billing client dan server bisa otomatis jalan saat komputer dihidupkan
Klik System > Preferences > Sessions > Startup programs
Klik Add untuk menambah Startup Programs
Isikan:
di Server billing
Name : Billing CCL Server
Command : cclfox
di Client
Name : Billing CCL Client
Command : cclcfox -host “ip address billing server” -name ws1
Tekan tombol Close
buat nama-nama client di server billing dengan cara klik tombol klien baru, masukan nama client misalnya ws1 click ok, lakukan langkah ini sesuai jumlah komputer yang ada di warnet anda contoh kalau diwarnet anda ada 5 client bisa memberi 5 client tersebut dengan nama “ws1, ws2, ws3, ws4, ws5)
Agar jika ada user lain yang mau memakai komputer bisa langsung memakainya dengan mengklik “Klik disini untuk mulai” di Server Billing CCL, klik kanan nama client, lalu beri tanda centang pada “perbolehkan klien memulai session baru”.

electronic schematic capture and simulation di Linux

noreply@blogger.com (Anonymous) — Sun, 21 Dec 2008 09:33:00 +0000

The gEDA project has produced and continues working on a full GPL'd suite and toolkit of Electronic Design Automation tools. These tools are used for electrical circuit design, schematic capture, simulation, prototyping, and production.

Currently, the gEDA project offers a mature suite of free software applications for electronics design, including schematic capture, attribute management, bill of materials (BOM) generation, netlisting into over 20 netlist formats, analog and digital simulation, and printed circuit board (PCB) layout.

The gEDA project was started because of the lack of free EDA tools for POSIX systems with the primary purpose of advancing the state of free hardware or open source hardware. The suite is mainly being developed on the GNU/Linux platform with some development effort going into making sure the tools run on other platforms as well.

GNU

noreply@blogger.com (Anonymous) — Mon, 08 Dec 2008 18:03:00 +0000

GNU is a computer operating system composed entirely of free software. Its name is a recursive acronym for GNU's Not Unix, it was chosen because its design is Unix-like, but differs from Unix by being free software and containing no Unix code. Development of GNU was initiated by Richard Stallman and was the original focus of the Free Software Foundation (FSF).

GNU is developed by the GNU Project, and programs released under the auspices of the project are called GNU packages or GNU programs. The system's basic components include the GNU Compiler Collection (GCC), the GNU Binary Utilities (binutils), the bash shell, the GNU C library (glibc), and GNU Core Utilities (coreutils).

GNU is in active development. Although nearly all components have been completed long ago and have been in production use for a decade or more, its official kernel, GNU Hurd, is incomplete and not all GNU components work with it. Thus, the third-party Linux kernel is most commonly used instead. While this kernel has not been officially adopted by the GNU project, some third-party software is included, such as the X.Org release of the X Window System and the TeX typesetting system. Many GNU programs have also been ported to numerous other operating systems such as Microsoft Windows, BSD variants, Solaris and Mac OS.

The GNU General Public License (GPL), the GNU Lesser General Public License (LGPL), and the GNU Free Documentation License (GFDL) were written for GNU, but are also used by many unrelated projects. :)

OPEN SOURCE

noreply@blogger.com (Anonymous) — Mon, 08 Dec 2008 15:43:00 +0000

Open source is a development methodology, which offers practical accessibility to a product's source (goods and knowledge). Some consider open source as one of various possible design approaches,

while others consider it a critical strategic element of their operations. Before open source became widely adopted, developers and producers used a variety of phrases to describe the concept, the term open source gained popularity with the rise of the Internet, which provided access to diverse production models, communication paths, and interactive communities.
