Setting The IP Address
To be able to communicate between two computers, we need to set the TCP/IP in each computer.
The figure samples below are For Ms Windows (Windows 7)
• Go to right down side of your windows, click the network logo, then click Open Network and Sharing Center
• Click Local area Connection
• Click Properties
• Choose Internet Protocol Version 4 (TCP/IPv4)
• Click Properties
• Choose Use the following IP address
• Set / write the IP address, for example: 192.168.0.1
and subnet mask : 255.255.255.0
• Click OK
Ip address for Computer A |
Do the same procedure for computer B, but use different IP address, for example 192.168.0.2
IP Address for Computer B |
To check the connection, we can use ping command,
Before doing the ping command, turn off the Windows Firewall first in both of computers (go to Control Panel--> Windows Firewall--> Turn off Windows Firewall)
To do the Ping Command :
• Go to Command Prompt (press Windows logo + R , then write CMD , then hit Enter)
• After Command prompt appear ( in computer A) write the ping command :
ping 192.168.0.2 then press Enter key
there must be reply from Computer B (192.168.0.2)
• Also, do ping from Computer B to computer A
ping 192.168.0.1 then press Enter key
must be reply from Computer A (192.168.0.1).
