It +waits for the result and prints the obtained information line by line, +then exits 0. It prints the mname, the rname, the serial number, and +the refresh, retry, expiration and minimum times, in that order, +separated by spaces. </li> + <li> If the domain exists but no relevant field has been found, it exits 1. </li> + <li> If the DNS answered but no answer is available, it prints a relevant +error message and exits 2. </li> + <li> By default, s6-dnssoa looks for DNS cache addresses in the +<tt>/etc/resolv.conf</tt> file. If the DNSCACHEIP environment variable is set +and contains a list of IP (v4 or v6) addresses, separated by commas, +semicolons, spaces, tabs, newlines or carriage returns, then this list +is used instead. </li> +</ul> + +<h2> Options </h2> + +<ul> + <li> <tt>-q</tt> : qualify. Qualifies <em>domain</em> before resolution, +according to suffixes found in <tt>/etc/resolv.conf</tt>. If the DNSQUALIFY +environment variable is set and contains a list of suffixes separated by spaces, +tabs, newlines or carriage returns, then this list is used instead. By +default, no qualification is used: if <em>domain</em> is not a FQDN, a dot +is just appended to it. </li> + <li> <tt>-r</tt> : random. By default, the program does not sort the +result, but prints them in the order received from the DNS. With this +option, it performs a random permutation on the results before printing +them. </li> + <li> <tt>-t</tt> <em>timeout</em> : if the resolution takes more +than <em>timeout</em> milliseconds, then it exits 99 right away with an error +message. By default, <em>timeout</em> is 0, which means no timeout. </li> +</ul> + +</body> +</html> |
