Can NFS run on a dhcp LAN?

ZhiYi · 12-09-2004, 12:07 PM

Hi,

I have 2 pcs running fedora core 2. I plan to use NFS for networking the 2 pcs. A router connects these 2 computers. Currently, the router is set to serve dhcp among the 2 pcs.

I read up this topic from a book titled 'Using Redhat Linux' by QUE publishing. The steps given are to edit the /etc/hosts file and to use Linuxconf for nfs. In both cases, the computer name must be given followed by the IP address.

My question is that since dhcp has no fixed IP addresses for the computers, how do I supply the IP addresses? Does NFS require static IP addresses or if not, how do I enable NFS on a dhcp network?
If NFS does require static IPs, will my network still be able to share internet connection and files if I disable the router as a dhcp server?

THanks for the replies.

The way that I have mine set up is that my router is configurable to supply specific ip addressed to a certain MAC address. I have this enabled that way I dont have to use the DNS to give me the ip address it will always be the same.

NFS doesn't require static IP's at all, but it does require DNS if you have a changing IP. getting a system to do dynamic dns updates from dhcp isn't that much fun though, and from a 2 node network, pretty pointless.

Hello,

THanks for the replies.

So, a MAC address is the identification number of a network card right? How do I find the MAC of the card?

just type ifconfig u'll find the disply of your ipaddress in that same text u can find the 12 digit hexadecimal number (for example 00-50-8D-AF-43-E5) like that.this is the mac address of your network card.

as root do an 'ifconfig eth0' should give you something like this

eth0 Link encap:Ethernet HWaddr 00:07:E9:B5:F9:Q5
