Half Duplex.

Check to see if mii-tool is installed. If it is, use that to change the duplex speed. By the way, the duplex mode will be based on the media it's directly connected to if you have it set to auto-negotiate (which is should be by default). If you plug one NIC into a switch or another NIC, and you plug the second NIC into a hub, then the first one will automatically configure to full duplex, while the second will configure to half (hubs are shared media, so only one party can send at a time).
