How to setup your Static IP

How to setup your Static IP's in various Linux Distros. You can get all of your IP address information from the IP Adresses tab on the QCP.

If you have a VZ account, simply reboot from the QCP.
OpenVZ will handle all of the IP address configuration.

If you have a XEN account, you will still need to reboot from the QCP.
But you will also need to update all of the IP address configuration files.

You can find out what Distribution you have installed, as well as your IP address, Netmask, Network, Broadcast, and Gateway by logging into the QCP.

Redhat based (CentOS, Fedora)

Using a text editor change your '''eth0''' file to reflect your new IP address information.
I have made the lines that need to be changed '''Bold'''.

DEVICE=eth0
ONBOOT=yes
BOOTPROTO=static
IPADDR=76.191.252.242
NETMASK=255.255.255.0
NETWORK=76.191.252.0
BROADCAST=76.191.252.255

Now do a service network restart and ping your new IP.

[root@vps network-scripts]# service network restart
Shutting down interface eth0:                              [  OK  ]
Shutting down loopback interface:                          [  OK  ]
Bringing up loopback interface:                            [  OK  ]
Bringing up interface eth0:                                [  OK  ]
[root@vps network-scripts]# ping 76.191.252.242

Debian based (Ubuntu)

Move to the directory where your '''interfaces''' file is located:

root@vps:/# cd /etc/network

CAT your '''interfaces''' file and you will see something like this:

# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface
auto lo
iface lo inet loopback

# The first network card - this entry was created during the Debian installation

auto eth0

iface eth0 inet static
        address 69.12.216.41
        netmask 255.255.255.0
        network 69.12.216.0
        broadcast 69.12.216.255
        gateway 69.12.216.1

Now using a text editor change your '''interfaces''' file to look like this:

# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface
auto lo
iface lo inet loopback

# The first network card - this entry was created during the Debian installation

auto eth0
auto eth0:1
iface eth0 inet static
        address 76.191.252.242
        netmask 255.255.255.0
        network 76.191.252.0
        broadcast 76.191.252.255
        gateway 76.191.252.1

iface eth0:1 inet static
        address 69.12.216.41
        netmask 255.255.255.0
        network 69.12.216.0
        broadcast 69.12.216.255
        gateway 69.12.216.1

I have put the lines that need to be changed in '''Bold''' type. Make sure you input the new IP address and Gateway on the address and gateway lines. Now restart your networking by typing in the following.

root@vps:/etc/network# /etc/init.d/networking restart

A quick ping check and you should be up and running.

[root@www network-scripts]# ping 76.191.252.242

Slackware based

First move to the directory that has your '''rc.inet1.conf''' file in it.

root@vps:/# cd /etc/rc.d

If you CAT your '''rc.inet1.conf''' you will see something like this:

root@vps:/etc/rc.d# cat rc.inet1.conf

# /etc/rc.d/rc.inet1.conf
#
# This file contains the configuration settings for network interfaces.
# If USE_DHCP[interface] is set to "yes", this overrides any other settings.
# If you don't have an interface, leave the settings null ("").

# Config information for eth0:
IPADDR[0]="69.12.216.41"
NETMASK[0]="255.255.255.0"
USE_DHCP[0]=""
DHCP_HOSTNAME[0]=""

# Config information for eth1:
IPADDR[1]=""
NETMASK[1]=""
USE_DHCP[1]=""
DHCP_HOSTNAME[1]=""

Using a text editor make '''rc.inet1.conf''' look like this:

# /etc/rc.d/rc.inet1.conf
#
# This file contains the configuration settings for network interfaces.
# If USE_DHCP[interface] is set to "yes", this overrides any other settings.
# If you don't have an interface, leave the settings null ("").

# Config information for eth0:
IPADDR[0]="76.191.252.242"
NETMASK[0]="255.255.255.0"
USE_DHCP[0]=""
DHCP_HOSTNAME[0]=""

# Config information for eth0:1
IFNAME[1]="eth0:1"
IPADDR[1]="69.12.216.41"
NETMASK[1]="255.255.255.0"
USE_DHCP[1]=""
DHCP_HOSTNAME[1]=""


# Config information for eth1:
#IPADDR[1]=""
#NETMASK[1]=""
#USE_DHCP[1]=""
#DHCP_HOSTNAME[1]=""

I made the lines that need to be changed '''Bold'''. Make sure you comment out the lines on the '''# Config information for eth1:''' line
or you will get an error.

Now restart your networking and do a ping check.

root@vps:/etc/rc.d# /etc/rc.d/rc.inet1 restart

[root@www network-scripts]# ping 76.191.252.242
PING 76.191.252.242 (76.191.252.242) 56(84) bytes of data.

Gentoo based

Fist move to the directory where your '''net''' file is.

localhost / # cd /etc/conf.d

CAT your '''net''' file and you will see something like this:

# /etc/conf.d/net:
# Global config file for net.* rc-scripts
iface_eth0="69.12.216.41 broadcast 69.12.216.255 netmask 255.255.255.0"
gateway="eth0/69.12.216.1"

Now you will need to add the following lines that are in '''Bold'''. You can get your IP address, broadcast, and netmask from the IP addressess tab on the QCP.

# /etc/conf.d/net:
# Global config file for net.* rc-scripts
iface_eth0="76.191.252.242 broadcast 76.191.252.255 netmask 255.255.255.0"
gateway="eth0/76.191.252.1"

alias_eth0=("69.12.216.41")
broadcast_eth0=("69.12.216.255")
netmask_eth0=("255.255.255.0")

Restart your eth0 and do a ping check.

/etc/init.d/net.eth0 restart
