Sharing Internet on a computer network is not difficult now, even on a network that has some differences in the operating system on each - each computer though.
In this article will be discussed regarding Internet connection sharing using PCLinuxOS as Gateway and Ms. Windows or other Linux as a client.
The reason I use Linux as the gateway is the ability to filter the attack from the outside better compared to using Windows as the Gateway.
As I write this article I use PCLinuxOS TinyMe 2008 on Fujitsu Notebooks Pentium III that I functioned as Mobile Computing and Gateway in my Lab. Basically, use and Configuration PCLinuxOS PCLinuxOS anyone else is that I use.
- Make sure there is login as root
- Prepare a computer unit that is installed PCLinuxOS with 1 or more NICs on the computer.
- Connect PCLinuxOS into the network (LAN) you either use a wired or wireless devices. Here I use UTP cable as a communication line IP (Internet Protocol) in my network.
- After PCLinuxOS is connected and all computers can be connected with PCLinuxOS is the next step is to make the connection the internet connection on PCLinuxOS. Here I use Dial Up Internet keoneksi GSM Telkomsel Flash (Telkomsel Flash Unlimited) using a mini USB cable and Motorola V3i as a modem. For other types of Internet connections can be adjusted and you confirm to the Provider.
- Since I use dial up internet connection so I use Gnome PPP as a dialer which already include the installation of PCLinuxOS TinyMe2008. After I run the motorola modem install Gnome PPP and go into the configuration by clicking on the button setup.
- After the configuration window open click detect button to detect the modem in automation. Make sure your modem is supported by PCLinuxOS.
- Once the modem is detected click on the button and input ATCommand Init String on AT1 .... because I use Telkomsel Flash Unlimited strings I use are as follows: AT + CGDCONT = 1, "IP", "internet"
- Then click OK to exit the windows Command.
- Enter the number dial on the go ..... because I use Dial up GSM then dial number I use is * 99 # or * 99 *** 1 #
- Then click the OK button to exit and return to the Gnome PPP dialer.
- Enter the same username as well as APN and Password.
- Fill in the dial number * 99 # or * 99 *** 1 #
- After all is finished try clicking the Connect button to establish connection.
- I think things went well. After doing internet connection sharing internet settings from PCC (PCLinuxOS Control Center)
- Select menu and select Network and Internet Internet share ......
- Configuration with Telkomsel Flash Unlimited:
- IP Telkomsel Flash: 192 168 100 101
- Primary DNS Server: 202.3.208.10
- Secondary DNS Server: 202.3.210.10
- Enter the IP Telkomsel Flash in column PCLinuxOS gateway and DNS server IP input Telkomsel Flash in column DNS Server PCLinuxOS
- Set in the fictitious requested by PCLinuxOS according to your LAN ....
- Usually PCLinuxOS will ask you to do istalasi Shorewall, do shorewall installation automatically, if the failure to install automatic install using Synaptic.
- After configuring PCLinuxOS finished, configure the NIC in the computer - the client computer by entering the IP Gateway and DNS from Provider PCLinuxOS.
- After all the configuration is running correctly every - every computer connected to the gatewai PCLinuxOS can enjoy the Internet run private along with other computers.
