Lan Connection Between Laptop And Desktop

I was able to connect two PCs with an ethernet cable.

Gave following ip to one PC
ip -> 192.168.1.2
mask -> 255.255.255.0
gateway -> 192.168.1.1

to other PC
ip -> 192.168.1.4
mask -> 255.255.255.0
gateway -> 192.168.1.3

this worked.

Guys,just join your comps with LAN cable and run "ip messenger"
