Same happens from ipcluster engine

Version is git from today.

The solution here is probably just to remove the url option. Connection files are the way to propagate connection info.

Can I ask why you are specifying the ip/port on the command-line?

[bfroehle]

Unfortunately I don't think you are actually using the git version from today, as I don't see any mention of disambiguate_url in ipengineapp.py

In particular, the line you mentioned disappeared in a70d89c many months ago.

I'm going to close this issue. Please re-open if you can reproduce under the current master or version 0.13. Since @minrk has a question, I'm going to let this stay open for now.

Thanks, @bfroehle. @JanSchulz, can you post the output of import IPython; print IPython.sys_info()?

[jankatins]

Thanks a lot, the problem was that my python install had several versions of ipython installed (from 0.12 to several 14.dev versions installed via egg and *.exe). After deleting every ipython file under \lib\site-packages and \scripts and reinstalling a new version I was able to connect the engine to the controller.

Re: the question about ip / port: its in the examples:

ipengine --help:
[...]
Examples
--------

    ipengine --ip=192.168.0.1 --port=1000     # connect to hub at ip and port
    ipengine --log-to-file --log-level=DEBUG  # log to a file with DEBUG verbosi

Re the ipython version: Funnily the above command showed a new commit (before deleting everything and with a still broken ipengine):

C:\Neuinstall\ipython>python -c "import IPython; print IPython.sys_info()"
{'commit_hash': '06a7a57',
 'commit_source': 'installation',
 'default_encoding': 'cp1252',
 'ipython_path': 'C:\\portabel\\Python27\\lib\\site-packages\\IPython',
 'ipython_version': '0.14.dev',
 'os_name': 'nt',
 'platform': 'Windows-7-6.1.7601-SP1',
 'sys_executable': 'C:\\portabel\\Python27\\python.exe',
 'sys_platform': 'win32',
 'sys_version': '2.7.3 (default, Apr 10 2012, 23:31:26) [MSC v.1500 32 bit (Intel)]'}

The *.exe seems to get a different version of the ipython...

Thanks again for your fast help!

[takluyver]

Glad it got solved. I don't think there's anything we need to do here, so I'm closing the issue.
