|
|
|
=item B<--nameservers>
|
|
|
|
Set nameserver to query (can be multiple).
|
|
The system configuration is used by default.

|
=item B<--search-field>
|
|
|
|
Set the search field used for 'expected-answer'.
|

|
|
What the server must answer (can be a regexp).
|
|
|
|
=item B<--dns-options>
|
|
|
|
Add custom dns options.

|
--dns-options='port=972' --dns-options='recurse=0' ...
|
|
|
|
=item B<--warning>
|
|
|
|
Threshold warning in seconds
|
