[erlang-questions] Help running Erlang as a Service on XP Embedded

Hi Robby,

Thanks for the suggestion.

I searched for files called ".erlang.cookie" and I only see two of them - should there be more?   I checked and these two files are identical, including contents, size, and date.

Any other ideas that may help?

Best Regards,

It is probably an Erlang cookie mismatch. I can't off the top of my head remember where Erlang stores the cookies by default. I always set them explicitly.

The mismatch is likely, since your Service will be running in a different context to your status invocation.

Hope this helps,

I need some help getting Erlang to run as a Windows service on XP Embedded.

I am using RabbitMQ for a project I have been assigned, which has Elang as a dependency. This works well on Windows 7, and Windows XP, but I also have to target XP Embedded.  This is a non-clustered configuration (currently all components are on one machine)

Everything runs well when I start all the components in the foreground.

If I start it as a service, I see epmd.exe, erl.exe, and erlsrv.exe running, but it seems like the broker does not respond:

C:\PROGRA~1\TICKET~1\TMDS\rabbitmq\sbin>rabbitmqctl.bat status

"c:\progra~1\ticketmaster\tmds\erlang\bin\erl.exe" -pa "C:\PROGRA~1\TICKET~1\TMDS\rabbitmq\sbin\..\ebin" -noinput -hidden  -sname rabbitmqctl -s rabbit_control
-nodename  -extra status

Status of node '' ...
Error: unable to connect to node '': nodedown
- nodes and their ports on DANIEL-WYSE: [{'RabbitMQ',1052},{rabbitmqctl,3072}]
- current node: ''
- current node home dir: C:\Documents and Settings\Administrator
- current node cookie hash: ak3qKWQRwDfzEGk9nwYiVQ==

Are there possibly permissions issues? I can grant the service permissions if I knew which ones applied.  Any other ideas?  I'd appreciate any help I can get
