Error when running VTS script using GENI-lib

[Abdul Navaz]

Hi 

I am doing experiment on VTS and trying to use GENI-lib.  I set up a GENI-lib as mentioned in the page  http://groups.geni.net/geni/wiki/HowTo/SetupGENILIB .  After that I was trying to run the script  “vts_test_L2MAC.py"  from the page "https://barnstorm.atlassian.net/wiki/display/VTS/VTS+Tutorial+Materials” . 

I have made changes to script by passing my username credentials . I have attached the file for the reference.  When I try to run the script I am getting the below error message. Could you please tell me how can I fix this issue.?

Abduls-MacBook-Pro:samples abdulnavaz$ python vts_test_L2MAC.py 

Traceback (most recent call last):

I think you may need to install the module m2crypto. If you are using MacPort, can you run the following and try it again?

sudo port install py27-m2crypto

I may have this module installed on my system already when I tested geni-lib set up. 

Thanks,

Xuan

Hello ,

Issue is fixed now.  Thank you professor. The problem was with missing module “m2crypto”.  Installing pcre , swig  then  m2crypto using “pip install m2crypto” fix the issue. Sorry for the trouble.

Abdul,

Can you pull the repo one more time? I think you are missing some modules. 

Best,
