The start procedure /etc/init.d/dnsd is parameterized by the configuration file/etc/default/TCP-IP-SV.dns. The job name, account and job class under which the daemon is to run can be set. You can also define whether the daemon is started automatically when POSIX starts.
Operation of the DNS resolver daemon is controlled by the configuration file /etc/resolv.conf. The configuration file can contain several entries which specify the information relevant to the DNS resolver.
The following types of entry exist:
nameserver entry
domain entry
search entry
options entry
Each entry is contained in a separate line in the configuration file and begins with the keyword (nameserver, domain etc.) in column 1. The keyword is followed by the entry’s parameters, each separated by a blank. The last parameter may not be followed by a blank. The keywords of the /etc/resolv.conf entries are expected in lower case.
Lines in /etc/resolv.conf which begin with a semicolon (;) are interpreted as comment lines.
