All, I am a new NOX/OpenFlow user with what I hope are simple build and execution questions:
1. Following the build and installation instructions in noxrepo.org's manual results in a large number of 'make check' and './nox_core tests' errors. I have tried building with the git files on two different machines running Ubuntu and Xubuntu 9.04 with the same results. These are clean installs of X/Ubuntu and as far as I can tell all of the dependencies listed are installed and up to date with the Ubuntu repositories. I have attached the './nox_core tests' output, but most of the errors are of the following form: *ImportError: Import by filename is not supported. ../../../../../src/nox/netapps/tests/tests.cc(115): fatal error in "nox.netapps.tests.pyunittests.storage_test.testAddthenPutWrongTable": Unable to import twisted.trial.reporter. All of these errors seem to mention Twisted, but I have ver. 8.2.0-2 of python-twisted installed. I have tried running the installation commands and 'make check' from root without any changes. Any ideas as to where I am going wrong? I can provide more debug output if necessary. 2. Despite the above errors, I am able to connect my NOX controller to an external OpenFlow switch using './nox_core -i -v ptcp:6633 pyswitch.' However, the monitorsui and switchstatsws modules mentioned in the 'Setting Up a Virtual Testing Environment' tutorial return 'description not found' errors. Could these issues be related to the 'make check' errors, and what are these modules used for? 3. Although I can use nox_core to run a learning switch (pyswitch) on my OpenFlow box, I have yet to come across the ability to modify the flow table or manually add rules or entries as discussed in the OpenFlow whitepaper. Is there a specific NOX module that provides that ability, perhaps through the webserver functionality? Thank you very much for any and all assistance you can provide. I look forward to exploring the full potential of NOX/OpenFlow! Regards, Bradley Collins Clemson University
