You may also need to add a second IP address for complex group configurations. See the Configuring Groups tab after you have added the second IP address to your web server.
Request a new DNS name and IP address from your network administrator. The IP address you request must be in the same subnet as the existing IP address on your server.
If you use the suggested proxy by hostname configuration, be sure to request the creation of a wildcard entry to point to the same address. With proxy by hostname, you should also verify that the DNS entries with the Check DNS test. If the new IP is to be 24.249.162.195 and the DNS name is to be
In the following instructions, the DNS name ezproxy2.yourlib.org and the IP address 24.249.162.195 demonstrate where the DNS name and IP address should appear, and where you should insert your values instead.
These are the steps to add the second IP address to your existing network adapter under non-SUSE distributions of Linux.
cd /etc/sysconfig/network-scripts
ls ifcfg-*
n 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 OCLC Support.24.249.162.195 ezproxy2.yourlib.org
cp ifcfg-eth0 ifcfg-eth0:
DEVICE= eth0:0
24.249.162.195
./ifup eth0:0
su
command.cd /etc/sysconfig/network-scripts
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./etc/hosts
and add a line for your new address and name such as:
24.249.162.195 ezproxy.yourlib.org
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.
/etc/init.d/network restart
To tell EZproxy to use this name and address, edit config.txt 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.
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 an 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.
