You need to configure your eth0.
Open a console window and type:
redhat-config-network
You will need to add eth0.
Click Add, then select Ethernet Connection, and then select Ethernet Card eth0.
Then choose to setup a Static IP.
Code:
Address: 192.168.1.1
Subnet Mask: 255.255.255.0
Default Gateway Address: 192.168.1.1
After, select eth0 and click Activate.
At the command line, use
ifconfig to confirm that eth0 has the correct IP (192.168.1.1).
You will also need to configure WindowsXP with a static IP (192.168.1.2) and a default gateway (192.168.1.1).
You can also use
ping to ping between both system.
Then we can move to the next step.
NOTE: you should edit your previous post and remove your IP for security reasons.
