You have to match Ethernet signal pairs to physical wire pairs. Free Port Scanner is a small, fast, easy-to-use and robust port scanner for the Win32 platform.

But you have B+ and C+ on the orange pair and C- and B- on the green pair. You have A+ and A- on the blue pair and D+ and D- on the brown pair, which is fine.

Update: Your wiring pattern is incorrect. The other four wires are used but are not crossed since auto-MDIX is mandatory at the higher data rates (1000BASE-T transmits and receives on all pairs simultaneously without any dedicated send/transmit pairs). Newer routers, hubs and switches (including some 10/100, and all 1 Gigabit or 10 Gigabit devices in practice) use auto-MDIX to automatically switch to the proper configuration once a cable is connected. Gigabit speeds and crossover cables don't mix because Gigabit combines transmit and receive functions on the same wires. Modern network interfaces have auto-MDIX and don't need crossover cables.

Download Free Ethernet crossover cable PNG Images, Crossover Suv. Don't ever use a crossover cable to connect a Gigabit device to anything unless you have some very specific and incredibly unusual reason to do so.
