GNU adns
-
+
Advanced, easy to use, asynchronous-capable DNS client library and
utilities.
-
+
adns is a resolver library for C (and C++) programs, and a collection
of useful DNS resolver utilities.
-
+
C library
In contrast with the standard interfaces, gethostbyname et al and
TCP in case of long replies or queries, or to other nameservers if
several are available. It has sensible handling of bad responses
etc.
-
+
DNS utility programs
adns also comes with a number of utility programs for use from the
general-purpose DNS helper program for scripting languages which
can invoke and communicate with subprocesses. See the [1]adnshost
usage message for a summary of its capabilities.
-
+
Forthcoming:
I hope that future versions may also have the following features:
* Possibly some very limited caching behaviour.
* There was, at one point, a draft native Perl interface from Tony
Finch.
-
+
Documentation
I'm afraid there is no manual yet. However, competent C programmers
should be able to use the library based on the [2]commented adns.h
header file, and the usage messages for the programs should be
sufficient.
-
+
Feedback
I'd be pleased if you would let me know if you're using my library in
your project, and what you think of it.
-
+
If you are subscribed to adns-discuss please send feedback, including
bug reports, there; otherwise send mail to
adns-bugreports@chiark.greenend.org.uk. If you'd prefer that your
message wasn't forwarded to the adns-bugreports list, send it to
adns-maint@chiark.greenend.org.uk.
-
+
Mailinglists
I have set up mailinglists adns-announce and adns-discuss. The
announcements list is moderated and will contain only announcements of
important bugs, new versions, etc. The bug reports address mentioned
above is also a mailing list; feel free to subscribe to it.
-
+
There are [3]archives and subscription web pages, or you can subscribe
by sending mail containing the word `subscribe' to
adns-announce-REQUEST@chiark.greenend.org.uk or
adns-discuss-REQUEST@chiark.greenend.org.uk.
-
+
Download
Available for download from [4]chiark.greenend.org.uk are:
adnshost (currently there is no manual, sorry).
* All versions released so far are also available via [8]anonymous
FTP and [9]HTTP.
-
+
You can also access the project CVS repositories:
* A mirror of the source code repository is available via rsync from
rsync.chiark.greenend.org.uk::ftp/users/ian/cvs-pub/adns (use FTP
first to find your way around), or via [10]cvsweb.
* This web page is maintained in [11]Savannah, where you can browse
the [12]webpage CVS.
-
+
adns is also available from the [13]GNU Project FTP servers and their
[14]mirrors.
-
+
Technical note
adns requires a real nameserver like [15]BIND or [16]Dents running on
`recursive service'. I.e., adns is a `stub resolver'. All properly
configured UN*X and GNU systems will already have such nameserver(s);
they are usually listed in /etc/resolv.conf.
