The router assigns an IP address to machine A aaa.bbb.ccc.ddd, and then also assigns machine B the sam aaa.bbb.ccc.ddd address? If that is the case, then the two machines will never be able to talk to each other. For that matter, your should be running into other network problems. Lets double check this. On the two machines, run: /sbin/ifconfig The "inet addr:" for lo should be 127.0.0.1 on both machines, but should be different for eth0 (or what ever your interface to the router is.) If they are the same, then take a look at /etc/sysconfig/network-scripts/ifcfg-eth0. Make sure it is not set up for a static IP address. It may have more or less lines, but it should look something like this: (HWADDR and DHCP_HOSTNAME for your system or missing.)
