Hi，
I installed a NOX on 64 bit version Ubuntu. I run the nox and
nox-gui.py, but I get a error message.
This error message is as follows:
~/wunyuan/original/nox/src$ ./nox-gui.py
Traceback (most recent call last):
File "./nox-gui.py", line 20, in <module>
import gui.log as log
File "/home/nchc10/wunyuan/original/nox/src/gui/log.py", line 7, in
<module>
from PyQt4 import QtGui, QtCore, QtSql
ImportError: cannot import name QtSql
How can I fix this error?
Best regards,
Wun-Yuan

Right; I was unclear earlier. This bug should only appear on 32 bit
Pythons. On Pythons with 64 bit integers, these are not long integers
and have no L suffix.
This is basically a bad behavior for the hex() function, and I believe
this was *intended* to be fixed in Python 2.x, but was accidentally
missed and now is only fixed in Python 3. The solution for us is to
use "0x%x" % (n,)) or hex(n).rstrip("L") or something instead of the
plain hex(n). We'll push a fix for this at some point.
Thanks again for pointing out the problem.

Dear Murphy，
My NOX controller is 32 bit and two clients are 32 bit. When the two
clients ping each other, this problem still occur.

Dear Murphy，
I forgot that our client are 64 bit version.Thanks for your
reminding me.

Ah, of course, you must be running a 32 bit version.
We should fix this (maybe by replacing hex(n) with "0x%x" % (n,)).
Thanks for humoring me.

I'm a bit surprised. Can you try "/usr/bin/python -V"?
Yes
nchc@NCHC:/usr/bin$ ./python -V
Python 2.7.1+
What OS / distro are you using?
nchc@NCHC:/usr/bin$ lsb_release -a

Thanks!

Are you using Python 2.5? I am guessing this bug doesn't exist
with Python 2.6+...

Our Openflow are installed in Desktop PC with NetFPGA card.
Thanks.

This seems to be a bug where the component was expecting a
hex string, but the "L" in the end of the long int messes
things. Thanks for reporting.
What kind of switch are you using?
For a temporary fix in your case, try replacing line 95 with:
value = int(value[:-1],16)

Dear all，
I build a testbed as follows:
NOX
/ \
of1----of2
/ \
a b
Firstly, I set a and b to ping each other. Secondly, I
input "./nox_core -v -v -i ptcp:9550 routing lavi
monitoring trackhost_pktin" to run the NOX. and then
start nox-gui. Thirdly, I click "FlowTracer" botton and
then double click of1 node on nox-gui to show its flow
entries. Finally, I highlight one entry and click
"Trace!" botton. However,I cannot find any flows on
nox-gui and I find one error message. this error message
is as follows:
File "~/nox/src/gui/views/flowtracer.py", line 95, in
trace_flow
value = int(value,16)
ValueError: invalid literal for int() with base 16:
'0xe4115b1251b4L'
How could I fix it?
