It is usually used in conjunction with the \module{mactcp} -module, to map hostnames to IP addresses. It may not be available in -all Mac Python versions. -\index{Macintosh Domain Name Resolver} -\index{Domain Name Resolver, Macintosh} - -The \module{macdnr} module defines the following functions: - - -\begin{funcdesc}{Open}{\optional{filename}} -Open the domain name resolver extension. If \var{filename} is given it -should be the pathname of the extension, otherwise a default is -used. Normally, this call is not needed since the other calls will -open the extension automatically. -\end{funcdesc} - -\begin{funcdesc}{Close}{} -Close the resolver extension. Again, not needed for normal use. -\end{funcdesc} - -\begin{funcdesc}{StrToAddr}{hostname} -Look up the IP address for \var{hostname}. This call returns a dnr -result object of the ``address'' variation. -\end{funcdesc} - -\begin{funcdesc}{AddrToName}{addr} -Do a reverse lookup on the 32-bit integer IP-address -\var{addr}. Returns a dnr result object of the ``address'' variation. -\end{funcdesc} - -\begin{funcdesc}{AddrToStr}{addr} -Convert the 32-bit integer IP-address \var{addr} to a dotted-decimal -string. Returns the string. -\end{funcdesc} - -\begin{funcdesc}{HInfo}{hostname} -Query the nameservers for a \code{HInfo} record for host -\var{hostname}. These records contain hardware and software -information about the machine in question (if they are available in -the first place). Returns a dnr result object of the ``hinfo'' -variety. -\end{funcdesc} - -\begin{funcdesc}{MXInfo}{domain} -Query the nameservers for a mail exchanger for \var{domain}. This is -the hostname of a host willing to accept SMTP\index{SMTP} mail for the -given domain. Returns a dnr result object of the ``mx'' variety. -\end{funcdesc} - -\subsection{dnr result object} -\label{dnr-result-object} - -Since the DNR calls all execute asynchronously you do not get the -results back immediately. Instead, you get a dnr result object. You -can check this object to see whether the query is complete, and access -its attributes to obtain the information when it is. - -Alternatively, you can also reference the result attributes directly, -this will result in an implicit wait for the query to complete. - -The \member{rtnCode} and \member{cname} attributes are always -available, the others depend on the type of query (address, hinfo or -mx). - - -% Add args, as in {arg1, arg2 \optional{, arg3}} -\begin{methoddesc}[dnr result]{wait}{} -Wait for the query to complete. -\end{methoddesc} - -% Add args, as in {arg1, arg2 \optional{, arg3}} -\begin{methoddesc}[dnr result]{isdone}{} -Return \code{1} if the query is complete. -\end{methoddesc} - - -\begin{memberdesc}[dnr result]{rtnCode} -The error code returned by the query. -\end{memberdesc} - -\begin{memberdesc}[dnr result]{cname} -The canonical name of the host that was queried. -\end{memberdesc} - -\begin{memberdesc}[dnr result]{ip0} -\memberline[dnr result]{ip1} -\memberline[dnr result]{ip2} -\memberline[dnr result]{ip3} -At most four integer IP addresses for this host.

Valid for ``hinfo'' -queries. -\end{memberdesc} - -\begin{memberdesc}[dnr result]{exchange} -The name of a mail-exchanger host. Valid for ``mx'' queries. -\end{memberdesc} - -\begin{memberdesc}[dnr result]{preference} -The preference of this mx record. Not too useful, since the Macintosh -will only return a single mx record. Valid for ``mx'' queries only. -\end{memberdesc} - -The simplest way to use the module to convert names to dotted-decimal -strings, without worrying about idle time, etc: -\begin{verbatim} ->>> def gethostname(name): -... import macdnr -... dnrr = macdnr.StrToAddr(name) -... return macdnr.AddrToStr(dnrr.ip0) -\end{verbatim} |
