Add an IP address for Non-SUSE distributions
These are the steps to add the second IP address to your existing network adapter under non-SUSE distributions of Linux.
Become root on your system, either by logging into that account or using the su command.
Change your current directory to the /etc/sysconfig/network-scripts directory with the command:
cd /etc/sysconfig/network-scripts
Check for existing network adapters with the command:
ls ifcfg-*
In most instances, you will see the files ifcfg-eth0 and ifcfg-lo. If you see other files with any other names and are unfamiliar with configuring TCP/IP, you may want to consult with your system administrator before proceeding or contact support@oclc.org.
Edit /etc/hosts and add a line for your new address and name such as:
24.249.162.195 ezproxy.yourlib.org
To create the new interface, you will copy ifcfg-eth0 to ifcfg-eth0:0 with the command:
cp ifcfg-eth0 ifcfg-eth0:0
Next, edit icfg-eth0:0 and change the DEVICE line to be similar to:
DEVICE=eth0:0
and change the IPADDR line to be similiar to:
IPADDR=24.249.162.195
To activate the new IP address, issue a command similar to:
./ifup eth0:0
Add an IP address for SUSE distributions
These are the steps to add the second IP address to your existing network adapter under SUSE distributions of Linux.
Become root on your system, either by logging into that account or using the su command.
Change your current directory to the /etc/sysconfig/network-scripts directory with the command:
cd /etc/sysconfig/network-scripts
Check for existing network adapters with the command:
ls ifcfg-eth*
and look for a file named similar to ifcfg-eth-id-12:34:56:78:90:ab. The colon-delimited letters and digits at the end are the MAC address (hardware address) of the Ethernet adapter.
Edit /etc/hosts and add a line for your new address and name such as:
24.249.162.195 ezproxy.yourlib.org
To create the new interface, you will edit ifcfg-eth-id-12:34:56:78:90:ab. The file should contain lines similar to:
BOOTPROTO='static'
BROADCAST='24.249.162.255'
IPADDR='24.249.162.194'
NETMASK='255.255.255.0'
NETWORK='24.249.162.0'
STARTMODE='onboot'
USERCONTROL='no'
_nm_name='bus-pci-0000:01:04.0'
and will contain additional lines. At the bottom of this file, you should add lines similar to:
IPADDR1='24.249.162.195'
NETMASK1='255.255.255.0'
LABEL1='0'
to add the extra address and then you should issue:
/etc/init.d/network restart
to restart networking and activate the new IP address.
Reconfigure EZproxy to use a specific IP address
To tell EZproxy to use this name and address, edit config.txt/ezproxy.cfg and add lines similar to:
Name ezproxy.yourlib.org
Interface 24.249.162.195
These lines should appear before any LoginPort, LoginPortSSL, or Title lines.
Reconfigure Apache to use a specific IP address
You will also need to configure your existing web server to tell it to use only its IP address. In Apache, you do this by editing httpd.conf and changing your Listen lines like:
Listen 80
to
Listen 24.249.162.194:80
where 24.249.162.194 would be replaced by the main IP address of your server.
These are the steps to add the second IP address to your existing network adapter under non-SUSE distributions of Linux.
Become root on your system, either by logging into that account or using the su command.
Change your current directory to the /etc/sysconfig/network-scripts directory with the command:
cd /etc/sysconfig/network-scripts

and change the IPADDR line to be similiar to:
IPADDR=24.249.162.195
