When installing Linux on your target lab server, follow the guidelines explained in this section.
The NNLS installation and configuration mechanisms require that your lab server use a static IP address rather than obtaining its address through DHCP. This means you must manually change the IP address settings in the RedHat and SuSE installs, both of which use DHCP by default.
When prompted for a hostname during the Linux install, remember that the hostname doesn't include DNS domain information. For example, enter only mylinuxbox.
Do not include the DNS domain information with the hostname (for example, mylinuxbox.mylab.mycompany.com).
If you include the domain with the hostname, eDirectory and other NNLS components will not install correctly.
When partitioning your server's hard drives, you must plan for the items shown in Table 1.
Table 1. Lab Server Partition Requirements
After you install Linux, you must do the following to ensure proper resolution of the server's IP address by NNLS products.
Edit the /etc/hosts file on the server.
If present, remove the servername variable from the
127.0.0.1 servername localhost.localdomain localhost
line so it reads
127.0.0.1 localhost.localdomain localhost
Add the following line to the hosts file (if not already present):
serverip fullyqualifiedhostname servername
where serverip is the IP address of the NNLS server, fullyqualifiedhostname is the server's fully qualified hostname, and servername is the hostname of the lab server.
For example, you might add the following to the /etc/hosts file:
10.1.1.1 mylinuxbox.mylab.mycompany.com mylinuxbox
