Sorry to start up another version question but similarly to the OpenFlow
0x98 thread I'm having problems with newer openflow reference systems.
Luckily 0.8.9 with 0X97 is fine for me, however (embarrassingly) I can't
seem to find the 0.8.9 release anywhere on the openflowswitch.org site.
The downloads page only has the 0.8.9~2 and 1.0.0 reference systems and
the most modern previous version listed is 0.2.1.
Alternatively, another openflow page suggests
1. git clone git://noxrepo.org/nox
2. cd nox
3. git checkout -b nox0x98 origin/openflow-1.0
will produce an OpenFlow 1.0 compatible nox version.
After building the latest versions of openflow and nox from git and
branching as above and running nox/openflow as generally specified in
http://noxrepo.org/manual/using.html#setting-up-a-nox-network the
ofprotocol connection fails with the following error on the openflow side:
Jan 05 11:40:53|00009|vconn|WARN|tcp:10.0.0.2:2525: version negotiation
failed: we support versions 0x98 to 0x98 inclusive but peer supports no
later than version 0x01.
and:
00001|nox|WARN:Received error during handshake (0/0)
on the nox side. The openflow was built using
git://openflowswitch.org/openflow.git this morning and nox was pulled
this morning. Is this a known problem, and/or am I messing something up?
Finally, is using the OpenFlow1.0 controller with nox0.6 preferable? Or
is it better just to stick with an older 0x97 compatible openflow
reference system for now?(if I can find one) Thanks!

Hi,
This is probably because --with-openflow is somewhat hard to maintain.
We are doing away with it for further versions.
If you do not need any specific feature in 0x98, I would recommend
going with 0x97 in
* openflowswitch.org/openflow (release/0.8.9)
* noxrepo.org/nox (do not use --with-openflow option in configure)
If you need some particular feature beyond v0.8.9, let us know. We
can figure something out then.
Hope this is helpful.

Sorry for double-message KK: replied rather than replied all, using an email
client I've never used before!
I'm using NOX straight from git://noxrepo.org/nox - `git log` shows the last

I've tried against OpenFlow 0.8.9r2 from this tar:
http://openflowswitch.org/downloads/openflow-0.8.9~2.tar.gz as well as 0.9.0r1
from this tar: http://openflowswitch.org/downloads/openflow-0.9.0-rev1.tar.gz
and OpenFlow (1.0) straight from git://openflowswitch.org/openflow with last

Add new OpenFlow error messages for 1.0 release.
The quoted compile error is against the git openflow release, though I get
similar ones against openflow 0.9.0, referring to expire events not existing.
Compiling against 0.9.8 I get told:
../../../src/lib/openflow.cc: In member function ‘int
vigil::Openflow_connection::send_add_snat(uint16_t, uint32_t, uint32_t,
uint16_t, uint16_t, uint16_t, uint16_t, vigil::ethernetaddr, uint16_t)’:
../../../src/lib/openflow.cc:612: error: ‘struct nx_snat_config’ has no member
named ‘mac_addr’
I am always compiling using:
make clean && ../configure --with-python=yes --with-openflow=/home/daw63/openflow
&& make
with /home/daw63/openflow being a symlink to the relevant release I'm trying to
use.
Thanks for getting back to me,
Daniel

Hi Daniel,
Are you compiling NOX for OpenFlow v0.9? Basically, I would like to
know where and how you got the OpenFlow source. That will help in
resolving your question.

Hi,
I'm trying to get a version of NOX which is compatible with OpenFlow 0x98.
Compiling the version from git://noxrepo.org/nox or git://noxrepo.org/noxcore
both give me compile errors about undefined classes when setting
--with-openflow to any of 0.8.9r2, 0.9.0 or the openflow git. Can anyone point
me at somewhere I can get a newer version of NOX?
The specific compiler errors I'm getting (against openflow from git) are:
