Alvaro Saurin bbd69170f9 zettio/weave#366 - improved configuration for th DNSServer, where we can specify the local domain name among other things... (missing some unit tests for this customized local domain) 2015-02-26 10:51:48 +01:00
Alvaro Saurin 419138ec6a zettio/weave#362 - use a WaitGroup for the TCP/UDP goroutines: otherwise, WeaveDNS server just quits 2015-02-23 13:17:54 +01:00

Alvaro Saurin 9c7ffd9b81 zettio/weave#362 - improve the unit tests for the TCP server by checking if we get all the responses with TCP when a previous UDP query resulted in a truncated response. 2015-02-23 13:17:54 +01:00

Listen on TCP on port 53 by default

Bryan Boreham 04a7aa1405 Use buffer size 4096 on advice from a DNS expert 2015-02-04 14:58:21 +00:00

Bryan Boreham 458ef12da6 Use a larger buffer than the default, so that more queries will succeed 2015-02-02 13:26:44 +00:00
Bryan Boreham e5a08a505d Change DNS fallback test to use a locally-run server to generate long responses reliably 2015-02-02 13:24:37 +00:00
Bryan Boreham 9ae3f4c692 Only read /etc/resolv.conf once 2015-02-02 13:16:05 +00:00
Michael Bridgen db9bae4162 Use the fallback for reverse lookups too 
I considered a couple of different factorings, that is

 * Implementing the fallback as a Lookup
 * Having a server struct that held the resolv.conf and methods for
   handling queries

but ultimately, this is simple and works.

Michael Bridgen ff45bcf945 Change Lookup method names 
The Local was redundant (and inaccurate in the case of the mDNS client
implementation), and otherwise they are too nondescript.
 2015-01-12 17:42:23 +00:00
Michael Bridgen 5f642d390c Pass queries for non-local names on to the configured nameserver 2015-01-12 17:12:15 +00:00
Michael Bridgen b114735a41 Reform logging in weaveDNS 
* Put prefixes (including msg IDs) in front of log messages to
   distinguish them
 * Failed lookups get logged under Info as per issue #311
 * More accurate messages as per issue #311

Bryan Boreham bd2844d186 Split http-startup code from server-startup 2015-01-08 18:38:38 +00:00
Michael Bridgen bf752d2d1f Implement zone lookup with MDNSCLient 
This separates Zone into the DB ops and the Lookup ops, and implements
the latter for MDNSClient so it can be used just like the zonedb.

A notable change is that Lookup methods only ever return one result,
while MDNSClient.SendQuery could in theory return multiple results
(though it wouldn't, because no server would supply more than one
result in a response, and it stops waiting after getting one response
..).

ReverseLookupLocal is implemented even though no MDNSServer will
answer at present (hence no test yet).

Lastly, the handler (creating) functions can now be given a list of
Lookup implementations to try in order.

Michael Bridgen 3866bd5e63 Parse reverse address lookup IPs in the Zone 
.. rather than making clients of the zone do it. At the minute there's
only one call site, but soon there will be more.

Michael Bridgen 8469fea215 Move files around in preparation for melding into weave code 
* library code will go in weave/nameserver/
 * main.go for the server goes in weavedns/ with the containerising
