Chapter 7. General Usage Information
NOTE
You must run dsktune as root.
On Solaris, dsktune automatically checks the patches and compares them with the current Sun
recommended patch lists. If it detects that the system is missing an important patch, dsktune will
notify you, even if the patch is for package that is not installed yet.
The command to run dsktune is as follows:
/usr/bin/dsktune
The dsktune utility then scans the system for required patches and dependencies.

7.7.2.1. Problem: Clients cannot locate the server
Solution.
First, modify the hostname. If that does not work, use the fully-qualified domain name, like
www.domain.com, and make sure the server is listed in the DNS. If that does not work, check the IP
address.
If the NIS domain is not the same as your DNS domain, check your fully-qualified host and domain
name.
