I know this is a FAQ, but it's not in the FAQ list and I've had no luck finding a good answer via web or list searches (Windows is a lousy search term, and service isn't much use in a Twisted context...) I want to run a tiny non-authoritative DNS server on my PC. I've never done this before, but twisted names looks ideal. The documentation (http://twistedmatrix.com/projects/names/documentation/howto/names.html) says I just need to do mktap dns --recursive --cache twistd -f dns.tap and indeed this works fine. I seem to recall some time ago seeing postings to the effect that tap format files were out of favour, but I don't follow the twisted list much, so I don't know if this is still true. Nevertheless, it works so who cares? However, I want to run this as a Windows service. Ideally, twistd would have a --install-service flag or something, but it doesn't so I went looking, and found postings covering tap2ntsvc which creates services from tap files, but it seems to have been replaced by ntsvc, which only handles .tac files :-( I get the impression that the idea is that .tac files are easy to create by hand, but as I know *nothing* about twisted names (and don't really want to - all I want is to run a DNS server!) it's not as easy as it might be... So, can someone tell me: 1. What is the currently favoured form for Twisted application files? 2. How do I make one for twisted names (the equivalent of the mktap line above) and better still how do I generalise this for any mktap command? 3. How do I run it? (twistd, presumably) 4. How do I make that file run as a Windows service? I believe, from what I've found, that the answers are: 1. .tac 2. Don't know - not sure there's a generic answer. 3. twistd -noy 4. ntsvc In which case, the documentation really needs to be updated to explain .tac files throughout, instead of mktap. And I need someone to write me a dns.tac file :-( Ideally, this should be written up as a FAQ or HOWTO somewhere. I'll volunteer to write it up, as long as someone will maintain it - I'm not in a position to do so (I use twisted occasionally, but have no need or desire to follow development versions or discussions on the list). I don't want to bother doing a write-up, if it won't get included in the docs/FAQ and maintained, though... Thanks in advance for any help, Paul.
