echo _service._protocol.nongnu.org | ruli-getaddrinfo echo _service._protocol.nongnu.org | srvsearch [ options ] echo _service._protocol.nongnu.org | sync_srvsearch [ options ] echo nongnu.org | smtpsearch [ options ] echo nongnu.org | sync_smtpsearch [ options ] echo nongnu.org | httpsearch [ options ] echo nongnu.org | sync_httpsearch [ options ] DESCRIPTION
This manual page documents briefly sample programs for the ruli(3) library. ruli is a library aimed at querying DNS SRV resource records. OPTIONS
For http searches, one can force the port number by specifying it as the first option. search Use the resolver search list defined in '/etc/resolv.conf'. need_ra Require RA (Recursion Available) bit in the name server answer. noinet Don't fetch IPv4 addresses. noinet6 Don't fetch IPv6 addresses. uri_port Assume the specified default port was forced by the user-supplied URI. nowalk Don't search addresses missing from the name server answer. nofall Don't launch fallback queries for addresses, if the SRV query fails. nosort6 Don't sort the address list to give preference to IPv6 addresses. EXAMPLES
echo _telnet._tcp.nongnu.org | ruli-getaddrinfo echo _smtp._tcp.nongnu.org | srvsearch search echo _smtp._tcp.nongnu.org | sync_srvsearch search noinet6 echo nongnu.org | smtpsearch noinet echo nongnu.org | sync_smtpsearch nowalk nofall echo nongnu.org | httpsearch noinet6 echo nongnu.org | sync_httpsearch 80 SEE ALSO
