Use custom DNS name servers to handle internal or private domain names and URLs. This topic describes how to add a new DNS server to your Domino Environment to allow access to additional domains and hostnames.
On a Linux host like your Domino executor, a configuration file at /etc/resolv.conf controls which DNS servers will be used to resolve hostnames.
You can use a pre-setup script in your Domino Environment to modify this file and add custom DNS servers by following these instructions.
-
Open the Environment you want to modify, then click Edit Definition.
-
Scroll down to the bottom of the definition, then click to expand the Advanced section.
-
In the Pre Setup Script field, enter the following lines of Bash. Fill in the address of the custom server you want to use where indicated.
echo 'nameserver your-custom-server-address' > /tmp/resolv.conf.tmp cat /etc/resolv.conf >> /tmp/resolv.conf.tmp cat /tmp/resolv.conf.tmp > /etc/resolv.conf -
Click Build at the bottom of the definition page to create a new version of the Environment.
Following a successful build, you can use this Environment to reach hosts through the added DNS name server.
