BusinessObjects Enterprise Administrator's Guide

Configuring the hosts files

On each machine running a BusinessObjects Enterprise server, you must configure the hosts file so that the server can map the FQDN it receives from the Central Management Server (CMS) to an internally routable IP address. This is necessary to enable communication between servers inside the firewall.

The procedure for configuring the hosts file is different for Windows and UNIX. See:

To configure the hosts files on Windows
  1. Open the hosts file using a text editor like Notepad. The hosts file is located at \WINNT\system32\drivers\etc\hosts.
  2. Follow the instructions in the hosts file to add an entry for each machine behind the firewall that is running a BusinessObjects Enterprise server or servers. Use the internally routable IP address of the machine and its externally routable fully qualified domain name.
  3. Save the hosts file.
To configure the hosts files on UNIX

Note:    Your UNIX operating system must be configured to first consult the hosts file to resolve domain names, before consulting DNS. Consult your UNIX systems documentation for details.

  1. Open the hosts file using an editor like vi. The hosts file is located at \etc\hosts.
  2. Add an entry for each machine behind the firewall that is running a BusinessObjects Enterprise server. Use the translated IP address of the machine and its fully qualified domain name.
  3. Save the hosts file.
  4. On the firewall machine, add a route from the translated IP address to the actual internal IP address:
  5. route add translatedIPaddress actualIPaddress

    Where translatedIPDaddress is the actual translated IP address, and actualIPaddress is the actual internal IP address for the a server.
