JeremyRand commented 9 years ago

I'm not certain, but maybe something else is already listening on the port that the REST API (Bottle) wants to listen on?

@phelix , any ideas?

phelixbtc commented 9 years ago

@rinchen As @JeremyRand said, make sure there is nothing else on the port, e.g. a daemon instance of nmcontrol (try python ./nmcontrol stop)

Any particular reason you are using 127.0.0.2 instead of 127.0.0.1 ?

rinchen commented 9 years ago

@phelixbtc good catch on 127.0.0.2. I am specifically NOT using that:

 1 [dns]
  2 ; Launch at startup
  3 ;start=1
  4
  5 ; Listen on ip
  6 host=127.0.0.1
  7
  8 ; Disable lookups for standard domains
  9 disable_standard_lookups=1
 10
 11 ; Listen on port
 12 ;port=53
 13
 14 ; Forward standard requests to
 15 resolver=127.0.0.54,10.10.10.1

127.0.0.54 is dnscrypt

rinchen commented 9 years ago

@JeremyRand I made sure nmcontrol was not running (ps ax | grep nmcontrol and then kill).

rinchen commented 9 years ago

I've also tried stopping dnscrypt with no improvement

rinchen commented 9 years ago

@phelixbtc if I comment out host=127.0.0.1 it still forces 127.0.0.2

phelixbtc commented 9 years ago

@rinchen Ah, I was too quick and mixed up the DNS address and the http (bottle) address. 127.0.0.2 is the default for the http server. To change the http server settings edit plugin-http.conf and maybe change ip address and/or port in there.

rinchen commented 9 years ago

@phelixbtc I don't get that error when I use --http.host=127.0.0.1 :-)

phelixbtc commented 9 years ago

@rinchen great maybe we need to change the default. @JeremyRand Was there any particular reason we chose 127.0.0.2?

phelixbtc commented 9 years ago

@rinchen And thanks for your feedback!

rinchen commented 9 years ago

in testing it works now, I think. I can do nslookup namecoin.org 127.0.0.1 and it works but nslookup nx.bit 127.0.0.1 fails. Namecoint.qt is still syncing so maybe that's at fault.

~/Library/Application Support/Namecoin/ exists but namecoin.conf inside it does not.

rinchen commented 9 years ago

and that's a user error. Fixing now.

rinchen commented 9 years ago

Ok it's working now but I need you to update https://github.com/namecoin/nmcontrol#prerequisites

I got this:

   raise Exception( "Error reaching Namecoin client (make sure Namecoin client is running and accepting RPC connections): " + str(e) + ' - Unable to send command : ' + str(body) )
Exception: Error reaching Namecoin client (make sure Namecoin client is running and accepting RPC connections): [Errno 61] Connection refused - Unable to send command : {"params": ["d/nx"], "method": "name_show", "id": 1}

and that's because namecoin-qt needed to be restarted. Please add "a) scramble the password in the above example" and "b) restart namecoin-qt before continuing" or something to that effect. Thanks!

rinchen commented 9 years ago

btw, when going to http://127.0.0.1:8080/ I get a 404 not found

127.0.0.1 - - [11/Nov/2015 08:00:38] "GET / HTTP/1.1" 404 720

rinchen commented 9 years ago

Another doc update, https://github.com/namecoin/nmcontrol#dns-config-on-linux--mac-os-x--manual-dns-config-windows-7-and-below needs to point out that there MUST be a comma after your DNS entry otherwise nmcontrol throws errors (better error handling there might be the correct solution)

phelixbtc commented 9 years ago

https://github.com/namecoin/nmcontrol/pull/117/files
The http server is only for RPC currently so that 404 is expected.

JeremyRand commented 9 years ago

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256

@JeremyRand Was there any particular reason we chose |127.0.0.2|?

@phelixbtc I picked 127.0.0.2 because it was available on my machine. No other special reason. (I believe khal used 127.0.0.2 for NMControl-related things, but my memory is fuzzy.) Honestly any IP:port will be in use on someone's machine... possibly making a more clear error message and providing clear instructions to fix is more important than magically picking something that is rarely in use.

~/Library/Application Support/Namecoin/ exists but namecoin.conf inside it does not.

There are ways to access name data from Namecoin Core without setting a user/pass in namecoin.conf (either cookie authentication with RPC, or REST), but at the moment NMControl doesn't support them. It is also unlikely that they will be backported to the Namecoin 0.3.x branch. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2

allthingsgo commented 9 years ago

On my OSX10.9, I had a named running in the background... that's how I couldn't get nmcontrol up and running... Can nmcontrol.py be deployed where the machine is also running its own DNS service ? Once I stopped named process on OSX, nmcontrol seems to be working ...along with namecoin-Qt .

JeremyRand commented 9 years ago

@allthingsgo Can you make another issue for that question?

phelixbtc commented 9 years ago

@allthingsgo Maybe named was using one of the ports that nmcontrol is using by default. You can change ip addresses and ports in the nmcontrol conf files. Thanks for the feedback, if you there are still open questions please open a new issue as Jeremy suggested.

closing as solved
