Communication between two APIPA computers without DHCP Server

On the last Saturday Me and my friend are trying to connect two computers directly using a USB cable and start communication between these two computers without the help of any external DHCP server. As I mentioned in my previous post we cannot use ordinary USB cable to connect two computers directly. It may burn the USB port.

[ To know more about it please follow the link below.

In this project we avoid using router or any other DHCP servers. As we are not using the Ethernet adapters we cannot set any static IP address. So without the presence of external DHCP server and static IP address our both computers will get APIPA from Windows Operating System.

[ To know more about APIPA please click on the link below.

http://www.corenetworkz.com/2008/02/how-to-resolve-issue-when-ip-getting-is.html ]

So the IP address our computers got was 169.254.X.X range. Fortunately the IP address gained by our computers were in the range 169.254.1.X and it started to communicate with each other.

It is sure that APIPA computers can communicate each other as their subnet mask is 255.255.0.0 (Class B address). So as the subnet rules says the network address of APIPA is 169.254.0.1 and the broadcast address is 169.254.255.255. Any address comes in between these range can communicate each other. Because it is a private IP address we cannot use APIPA to get Internet connection to our computers. For Local networks and Intranet APIPA is enough.

Can I connect two Computers using USB cable

They argue like USB cable is not designed to connect two computers directly. But it is old man's story and connecting two computers using USB cable is so easy as connecting two computers using Ethernet cable.

USB cable use to connect two computers

The type of USB cable which is used to connect two computers directly is called Bridged USB cable. It is available in two different USB standards. They are USB 1.1 and USB 2.0 ,

The difference of standard is based on the speed of data transfer. In USB 1.1 the data transfer speed is 12 Mbps and that in USB 2.0 is 480 Mbps. It is very important to note that no other USB cables are designed for the purpose of connecting two computers directly. Using wrong USB cables to connect two computers may harm the USB ports of your computers.



Modes of working of Bridge cable

The bridged USB cable works in two different modes. They are

1. Link mode

2. Network Mode

In link mode two computers are connected through the bridged USB cable and the file sharing is enabled. In network mode multiple computers are connected and in addition to the file sharing the Internet too shared.

This week end was very interesting for me as me and my friends established a Local Area Network in their home. They have total six computers and two of them is running on Ubuntu Linux. After establishing the Local Area Network we implemented one propitiatory real time simulation software on this LAN by installing the software on all this computers. But the software works fine with the integrated data of from 5 computers and one computer is not connecting to it or connection rejects. So the techie in our mind got up and we start troubleshoot the issue.

At first we thought the issue is with the compatibility issue of Ubuntu and the software. But the first Ubuntu computer is working fine with the software and in careful analysis it is found that that computer is functioning more efficiently than other Windows based computers. So it is not the issue with Ubuntu. Then we confused what is the actual cause of the issue. Then I just checked the connection manager of the software and the error message was some thing like unpredictable date with many hexa decimal codes. So it has some thing with system date. We went to the non-functional computer and checked the system date. It was the default system date set when they installed Ubuntu in this. So we just set the system date and time with current date and time . The result was great the issue fixed. So here I am presenting steps to change computer date and time in Ubuntu linux when there is no date and time displays on system tray.

How to change system date and time in Ubuntu Linux

To change the system date and time in Ubuntu Linux from Administration is:

1. Click on system

2. Select Administration and go to Time and Date

3. Unlock Time and Date and enter password.

Now you can change the system time and date by changing the default settings there.
