i recently added a dlink router between my comp and the modem so that i can have my comp and my xbox on the internet at the same time. however, i need to configure the router so that i can have people still access my site and to do this i need to know my ip address. how do i find it and how do i keep it from changing. thanks

Check your router's configuration page. It should tell you everything you need to know. Your router will have your external public IP address, and it probably has a DHCP server that hands out private IPs to computers on your internal LAN. You should be able to input your Linux box's IP and make sure it always gets the same internal IP, or simply assign your Linux box an IP outside the range given by DHCP on your subnet. You'll want to set up port forwarding between your router and your Linux box -- again, check the router configuration.

As for getting a permanent public IP address, if your ISP uses DHCP you can't unless you upgrAade to a plan with a static public IP.

i think the last guy got confused, what i need is the ip address of the linux box itself, that is the only thing i dont know. basically the linux equivelent of the ipconfig command from windows

Oh, well in that case ifconfig (one letter difference ). Your initial post was vague, though, as to which IP address you needed. You should be specific as to exactly what you need.

/sbin/ifconfig

Use the redhat-network-config script to reconfigure a static IP address. Make sure it isn't in the range that would be assigned by the router's DHCP server.

Configure the router to forward the appropriate ports to the static IP address you assigned.
