A Bit of Networking Help Please.

[Argedion]

I have a print/file server that every time my router is reset give the printer a different IP address. I would like to make this a Static IP but am not aware how. I have about 9 devices that connect to the internet from the router. I want to keep the dynamic Ip's for those devices however the 1 server I want to have a static. It is a Linux Server just basic samba / with cups I share the printer with my wife so its important that she have access to it but her windows machine is stupid and wont scan for and adjust for the Ip. (Windows 7 Home Premium)

I would recommend static network addresses for servers, anyway. It's much easier that way.

You can set up a static network address by changing your /etc/sysconfig/network-scripts/ifcfg-xxxx file (xxxx is the name of your network interface, like eth0, em1, p33p1, etc...)

For example, here is the ifcfg file on one of my machines that has a static network address.

NM_CONTROLLED="yes"
BOOTPROTO=none
DEVICE="p33p2"
ONBOOT=yes
HWADDR=6C:62:6D:7C:0C:31
TYPE=Ethernet
IPADDR0=192.168.1.20
PREFIX0=24
GATEWAY0=192.168.1.254
DNS1=192.168.1.254
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="System p33p2"

chances are, on your system, these are the only 5 lines you will need to change:

BOOTPROTO=none ------------------------ 	BOOTPROTO=dhcp tells it to use DHCP and dynamic addressing
IPADDR0=192.168.1.20  ------------------- network address you wish to assign
PREFIX0=24 --------------------------------- netmask - equilivant to 255.255.255.0
GATEWAY0=192.168.1.254 ---------------- address of router/gateway
DNS1=192.168.1.254 ----------------------- address of your DNS server (I used my router address, which pulls DNS from my ISP)

Thanks for the quick response and help. I'll report back how it worked out.

Ok I first created a file but it didn't work. (did not have on in natively) so went opended up Network Manager. clicked on IP4 settings and changed the method to Manual
then added ipaddress, netmask, gateway
Dns server is same as router

clicked saved rebooted and it all worked well. So then I unplugged inet connection rebooted and again all was well. SAME IP all the way around thanks bro

You can also specify the MAC address and corresponding IP address in a configuration file for the DHCP Daemon.

this is what I ended up doing on the router. I reserved all the ip's for my servers. found that the other way router would still try to give the IP to other componets.
