Change DHCP to Static in RH9

jimbo · 03-29-2004, 08:05 AM

I am attempting to run NFS on my home lan. It would seem that converting to static IP addresses on each local machine would be easier than trying to resolve the address the router doles out. It is a D Link DWL 615+.

Is this a good plan? If so, how do I implent it?

it is not a bad idea.

in RH9, edit the scripts in /etc/syconfig/network-scripts

so you can change the file /etc/sysconfig/network-scripts to look something like:

Code:

DEVICE=eth0
BOOTPROTO=static
IPADDR=xxx.xxx.xxx.xxx
NETMASK=255.255.255.0
GATEWAY=yyy.yyy.yyy.yyy
ONBOOT=yes

where xxx.xxx.xxx.xxx is the ip address that you want your machine to have
and yyy.yyy.yyy.yyy is the ip of your router
(do this for both machines)

since you get the dns server info through dhcp, you will have to add the dns server addresses to /etc/resolv.conf

after you make the changes you can just reboot or do (as root from a commandline)

Code:

ifdown eth0; ifup eth0

If you are running servers such as apache, nfs or a database, it's better to use a static address on the server.

one more thing, make sure that you don't assign a static ip that is in the range of dhcp addresses that your router leases out.

Very good thanks. It sounds like I can leave DHCP enabled on the router for my kids windows machines, is that so?

leaving dhcp enabled shouldn't cause a problem (unless it is trying to give out an ip that a static machine is using)

Thanks for your help.
