how do i set a static ip?

ninja master · 11-10-2008, 07:58 PM

my network freaked out, and setting a static ip with ifconfig would say that my ip changed to the ip i assigned, but after that it would not access the net. i would specifically like to have the computer keep its static ip after reboots.

i plan on bringing my linux server to a friends to share files, and would like to be able to point directly at the server, without guessing its ip address. thanks!

You can set your IP with netconfig or editing /etc/rc.d/rc.inet1.conf
Just fill in the values for IPADDR / NETMASK for your network card and leave USE_DHCP empty.

You're not explaining your problem very well. Setting a static IP is trivial (once you know what configuration files to edit). However, being able to access the internet depends on a number of things including correct subnet and netmask settings, correct routing information and an available Domain Name Service.

So - you need to tell us more about how you're set up and what you want to do.

Netconfig for DHCP nad Static IP

Hi,

You could setup a static IP by doing as root from cli;

Code:

~#ifconfig -a                      #get recognized devices
~#ifconfig wlan0 192.168.0.10      #set to a available IP
~#route add default gw 192.168.0.1 #set to your gateway
~#route -n                         #show the route table
~#ifconfig wlan0 up                #should be up already
~#ping 192.168.0.1                 #ping your gateway
~#ping 208.69.32.130               #google.com IP
~#ping google.com                  #test DNS, if fail then
                                   #check /etc/resolv.conf

You should have your '/etc/resolv.conf' setup with your 'ISP DNS' nameservers.

Code:

 sample '/etc/resolv.conf';

search 192.168.1.1           #this would be your local dns/router

nameserver xxx.xxx.xxx.xxx   #ISP DSN 'replace xxx.xxx.xxx.xxx
                             #with IP from your ISP
nameserver 4.2.2.1           #Verizon third level DNS
nameserver 4.2.2.2
nameserver 4.2.2.3
nameserver 4.2.2.4

If this works for you then setup your '/etc/rc.d/rc.inet1.conf' with the information. I used the wlan0 device but the same would be true for the eth0 device.

yes, i was ifconfiging, but doing a total butcher job at it.

its a 192.168.1.x type network with a network mask of 255.255.255.0 type network. no rocket science to my network =D

ok so my "isp dns" would be my routers dns server? sorry, im a retarded rock star =)

Hi,

I corrected the previous post to reflect your router/modem IP. You should use the DNS supplied from your ISP.

adriv · 11-19-2008, 03:17 PM

While you're at it, you could start surfing via OpenDNS, in your /etc/resolv.conf, you just have to add their nameservers and put them at the top, like this:

Code:

nameserver 208.67.222.222
nameserver 208.67.220.220

Just another suggestion re using your machine in different locations:

I use my laptop at several locations with static IP required at each place. I have several versions of all the relevant files and once the machine has booted I move the appropriate files into place using the following simple script.

Code:

#!/bin/bash 
#
#sn:  setup network script
#
#usage: sn <location>
#
echo "Setting up network for : "$1
cp /etc/resolv.conf.$1 /etc/resolv.conf
cp /etc/hosts.$1 /etc/hosts
cp /etc/rc.d/rc.inet1.conf.$1 /etc/rc.d/rc.inet1.conf
/etc/rc.d/rc.inet1 restart
export LOCATION=$1
echo "Location is: " $LOCATION

For example to start work at 'uq' I execute 'sn uq' and 'resolv.conf.uq' is moved into resolv.conf etc etc.

I guess there are smarter ways to work this out automatically, but this manual approach is rock solid.
