[Pdns-users] installating powerdns - recurse agains root servers
Hi, Now i have been studying the installation for hours.. and still i havent found a way to make a simple setup.. I would like to install pdns-recursor, and have it to recurse up against the root servers.. but, i just cannot find out how to configure this. I have a running power dns service, where i have entered my ISP as recursor.. but they seems rather unrelayable.. so i hope someone can help me.. and yes i have read the documentation.. and google for hours, but.. i just cant make the right config :/ Best regards, -- mvh Michael Holm ___ Pdns-users mailing list Pdns-users@mailman.powerdns.com http://mailman.powerdns.com/mailman/listinfo/pdns-users
[Pdns-users] Building for windows
Hey guys, We're working on implementing geographically dispersed system and we need a geo IP DNS system. From all the raving reviews for PowerDNS, it seems to be the best choice. I'm attempting to build it, but I have a few questions. I downloaded the latest release pdns 2.9.22, but it doesn't have the powerdns.dsw file. I found this in the trunk of the subversion tree. Can I just check out this file, or do I need the whole source tree from svn to build on Windows? If I need the whole tree, where is the tag for 2.9.22 (or an svn revision number)? We currently use MsSQL as our DB server. If we create the required table and use the ODBC backend, can our applications update dns records directly in the db for PowerDNS to use? In other words, as nodes go online and offline for upgrades and maintenance, I'd like to dynamically add and remove records for our www subdomain from our own custom applications. Do I need to signal powerdns in any way to reload records from the db once they're been changed from a different application?

Re: [Pdns-users] SQLite3 problem during stress
On Mon July 20 2009 11:01:05 you wrote: Yes, updating only one zone at the time is very much acceptable - that the initial transfer takes quite long time does not matter. We do not want to use an active database due to memory / CPU footprint. If PowerDNS locks the table and let the other threads just wait for the lock like any other mutex it would probably be just fine with distributor-threads = 1. The problem of the SQLite database is that while a zone transfer is in progress, all other threads can't serve any records. This is because the complete table is locked by SQLite when records are updated and this also prevents reading records in other zones. Please keep this in mind for your installation. I want to note that indeed PowerDNS _crashes_ / _exits_ in the end due to the Database is locked error. Since I'm currently testing with OpenDBX I don't know íf this is something that is regarded as an OpenDBX or PowerDNS bug - but gsqlite3 did also crash during heavy load which (as stated before) makes me believe that it's backend agnostic. What you've shown me in your logs is that the PowerDNS opendbx backend gets an error from the SQLite library that the database is locked and the opendbx backend forces the distributor thread to recreate the connection to the database. The problem is that the sqlite3 backend of the OpenDBX library returns a fatal error when the database is locked instead of a timeout. This is fixed in the SVN trunk and the fix will be also be included in OpenDBX 1.4.2. The next problem is that the PowerDNS opendbx backend doesn't make use of timeouts at the moment and treats them as errors. I've already enhanced the PowerDNS opendbx backend but I have to test it as soon as I can and see if the problem is gone. I will create a patch and send it to you so you can test yourself. What I haven't seen in your log file excerpt is that the opendbx backend crashed with a segfault.
