3. Fields description

3.1 DNS needed for normal operation

Standalone machine will generally not use a DNS, except if they get connect to a larger network once in a while. Even then, they may use a DNS on this larger network.

Linuxconf checks at different times (boot time for one) for DNS connectivity. If the DNS fails to answer after few seconds, Linuxconf will complain about it and offer you to skip network configuration: A bad DNS configuration or a faulty one are real show stoppers (It often gives the impression the computer is hung).

This test is a saver, except if the machine does not have full time access to a DNS. The check box is just there to tell Linuxconf not to care that much about the DNS. It won't change the operation of the machine beside that.

3.2 Default domain

You generally enter here the domain you use most, generally the domain of your organisation.

3.3 Nameserver 1 2 and 3

You must enter an IP number, not a machine name. For a standalone which never connect to any larger network, this is optionnal.

3.4 Search domain

An alternative to the default domain are the "Search domain" fields. While this add some overhead to DNS search, it may be a good time saver if you talk regularly to several machines spreaded in different domain.

Note that using "Search domains" is exclusive to the "default domain" field. Use one or the others.
