There are some additional messages in there that I was not expecting. Including references to python. 

What command are you using to run the scripts?

You mentioned that you are using the examples unmodified with the exception of the location of the scripts?

Thanks

Sorry for the confusion, I should have worded my initial entry better.  I have tried the unmodified scripts as mentioned (only the file paths are modified to match our installation).  I also tried sending json-rpc commands to the server using python.  I'm familar with Python, but have never used Perl, which is why I attempted this.

Does the unmodified environment all work (using perl) but the issue is when using a custom python client script?

Note that we are looking to create a python client example. When this is ready, I'll let you know.

Thanks

The unmodified perl client script does not work.

Ok, thanks. It looks like an issue with running the server side javascript (test_server.js). Can you provide how this script is being called (the exact command on the command line)? Are you executing it via the dss.bat file?

I have the perl script working.  Typing in 127.0.0.1 instead of local host resolved the issue

Great! Is your custom python client also working?
