Hello everybody,
I'm trying to connect my C# application to my erlang application using OTP.NET. And I have problems  This is what I did:
I set up two erlang nodes and tried out communication between them:
Code: nick@miljenko:~$ erl -sname alice -cookie "SECRET"
Erlang R13B03 (erts-5.7.4) [source] [smp:4:4] [rq:4] [async-threads:0] [hipe] [kernel-poll:false]
Eshell V5.7.4 (abort with ^G)
(alice@miljenko)1> rpc:call(bob@miljenko, erlang, node, []).
bob@miljenko
Code: nick@miljenko:~$ erl -sname bob -cookie "SECRET"
Erlang R13B03 (erts-5.7.4) [source] [smp:4:4] [rq:4] [async-threads:0] [hipe] [kernel-poll:false]
Eshell V5.7.4 (abort with ^G)
(bob@miljenko)1> rpc:call(alice@miljenko, erlang, node, []).
alice@miljenko
Excellent. Then I downloaded OTP.NET (http://jungerl.cvs.sourceforge.net/viewvc/jungerl/jungerl/lib/otp.net/), built it using MonoDevelop 2.2.1 and then run OTP.NET's test example:
Code: nick@miljenko:~/Projects/otp.net/OtpTest1/bin/Debug$ ./OtpTest1.exe
Otp test...
Usage: /home/nick/Projects/otp.net/OtpTest1/bin/Debug/OtpTest1.exe nodename [cookie] [-notrace]
nodename - is the name of the remote Erlang node
cookie - is the optional cookie string to use
-notrace - disable debug trace
nick@miljenko:~/Projects/otp.net/OtpTest1/bin/Debug$ ./OtpTest1.exe alice@miljenko SECRET
Otp test...
This node is called nick123@miljenko and is using cookie='SECRET'.
Can't connect to node alice@miljenko
To this alice responded with:
Code: (alice@miljenko)2>
=ERROR REPORT==== 8-Mar-2011::10:44:40 ===
** Connection attempt from disallowed node nick123@miljenko **
I tried to figure out why is my C# node disallowed, but failed. Can anybody give me at least a slightest pointer in which direction to look for errors?
Also: is there any other way to connect C# and erlang? The thing is: I wrote an excellent erlang application and then I wrote really nice C# GUI for it (I thought OTP.NET will work out of the box since I found no bug reports ). It would be a real shame if I would have to rewrite the GUI in some other language...
Kind regards,
Nikola |

Thats typical message for wrong cookie. Please execute in your app erlang:get_cookie() to make sure it is not overwritten somewhere.
Make sure also, if OTP node has sname (not fully qualified name).
Regarding your question about connecting OTP and .NET. There is number of protocols, just pick up one suitable for your needs: HTTP, Protobuffs, Thrieft.. raw socket communication.

Oh, right, I totally forgot there are other was of communicating I think I'll go for TCP/IP.
