Release 2.3 Mon May 6 16:18:02 EST 2002 This is a another release of the pydns code, as originally written by Guido van Rossum, and with a hopefully nicer API bolted over the top of it by Anthony Baxter <anthony@interlink.com.au>. This code is released under a Python-style license. I'm making this release because there hasn't been a release in a heck of a long time, and it probably deserves one. I'd also like to do a substantial refactor of some of the guts of the code, and this is likely to break any code that uses the existing interface. So this will be a release for people who are using the existing API... There are several known bugs/unfinished bits - processing of AXFR results is not done yet. - doesn't do IPv6 DNS requests (type AAAA) - docs, aside from this file - all sorts of other stuff that I've probably forgotten. - MacOS support for discovering nameservers - the API that I evolved some time ago is pretty ugly. I'm going to re-do it, designed this time. Stuff it _does_ do: - processes /etc/resolv.conf - at least as far as nameserver directives go. - tries multiple nameservers. - nicer API - see below. - returns results in more useful format. - optional timing of requests. - default 'show' behaviour emulates 'dig' pretty closely. To use: import DNS reqobj=DNS.Request(args) reqobj.req(args) args can be a name, in which case it takes that as the query, and/or a series of keyword/value args. (see below for a list of args) when calling the 'req()' method, it reuses the options specified in the DNS.Request() call as defaults. options are applied in the following order: those specified in the req() call or, if not specified there, those specified in the creation of the Request() object or, if not specified there, those specified in the DNS.defaults dictionary name servers can be specified in the following ways: - by calling DNS.DiscoverNameServers(), which will load the DNS servers from the system's /etc/resolv.conf file on Unix, or from the Registry on windows. - by specifying it as an option to the request - by manually setting DNS.defaults['server'] to a list of server IP addresses to try - XXXX It should be possible to load the DNS servers on a mac os machine, from where-ever they've squirrelled them away name="host.do.main" # the object being looked up qtype="SOA" # the query type, eg SOA, A, MX, CNAME, ANY protocol="udp" # "udp" or "tcp" - usually you want "udp" server="nameserver" # the name of the nameserver. Note that you might # want to use an IP address here rd=1 # "recursion desired" - defaults to 1. other: opcode, port, ... There's also some convenience functions, for the lazy: to do a reverse lookup: >>> print DNS.revlookup("192.189.54.17") yarrina.connect.com.au to look up all MX records for an entry: >>> print DNS.mxlookup("connect.com.au") [(10, 'yarrina.connect.com.au'), (100, 'warrane.connect.com.au')] Documentation of the rest of the interface will have to wait for a later date. Note that the DnsAsyncRequest stuff is currently not working - I haven't looked too closely at why, yet. There's some examples in the tests/ directory - including test5.py, which is even vaguely useful. It looks for the SOA for a domain, checks that the primary NS is authoritative, then checks the nameservers that it believes are NSs for the domain and checks that they're authoritative, and that the zone serial numbers match. see also README.guido for the original docs. comments to me, anthony@interlink.com.au, or to the mailing list, pydns-developer@lists.sourceforge.net. bugs/patches to the tracker on SF - http://sourceforge.net/tracker/?group_id=31674
