5. Reboot the Linux machine to apply the changes.

2.2.2.3. DNS Requirements

It is very important that DNS and reverse DNS be working correctly on the host machine,

especially if you are using TLS/SSL or Kerberos with Directory Server.

Configure the DNS resolver and the NIS domain name by the modifying the

/etc/resolv.conf, /etc/nsswitch.conf, and /etc/netconfig files, and set the DNS

resolver for name resolution.

Edit the /etc/defaultdomain file to include the NIS domain name. This ensures that the

fully-qualified host and domain names used for the Directory Server resolve to a valid IP

address and that that IP address resolves back to the correct hostname.

Reboot the Red Hat Enterprise Linux machine to apply these changes.

2.3. HP-UX 11i

Directory Server runs on HP-UX version 11i only; earlier HP-UX versions are not supported.

Directory Server runs on a 64-bit HP-UX 11i environment as a 64-bit process.

Table 2.4, “HP-UX 11i” lists the hardware requirements. Section 2.3.1, “HP-UX Patches” lists

the required patches, and the recommended system configurations are in Section 2.3.2, “HP-UX

System Configuration”.
