Wireshark · Wireshark-dev: Re: [Wireshark-dev] Building OpenFlow 1.0 dissector for Wireshark 1.10.0 on Ubuntu 13.04

[Anders Broman <a.broman@xxxxxxxxxxxx>]

Hi,
That plugin has newer been offered to Wireshark and we have no knowledge of it. Any questions should
be directed to whoever wrote it.
BTW I planning to do a OpenFlow dissector in C. If you could share any traces of OpenFlow v 1.3 that would help.
Regards
Anders

Greetings,

Wireshark 1.10.0 was built from source on Ubuntu 13.04, (with gcc 4.7.3)

OpenFlow 1.0 dissector was also built from source using scons with this modification in 'Sconstruct' (copied from Sconstruct under Ubuntu 12.04):

# env = Environment(LINKFLAGS = '-flat_namespace')

env = Environment()

to work around this error:

$ scons install

...

scons: Building targets ...

gcc -o openflow.so -flat_namespace -shared packet-openflow.os plugin.os -L/usr/lib -L/usr/local/lib

gcc: error: unrecognized command line option '-flat_namespace'

scons: *** [openflow.so] Error 1

...

Would this '-flat_namespace' be required for the plugin to work properly on Ubuntu 13.04?

The share library 'openflow.so' was copied to '/usr/local/lib/wireshark/plugins/1.10.0/

The 'openflow.so' plugin does not show up in the About dialog box.

The modification to 'packet-openflow.c' was carried out as instructed here:

http://networkstatic.net/installing-wireshark-on-linux-for-openflow-packet-captures/

1/- Adding:

#define NO_STRINGS NULL

2/- Changing dissector_add() to dissector_add_uint() here:

void proto_reg_handoff_openflow()

{

    openflow_handle = create_dissector_handle(dissect_openflow, proto_openflow);

    dissector_add_uint(TCP_PORT_FILTER, global_openflow_proto, openflow_handle);

}

Did I miss something?

Thanks for your help.

Regards,

PhiHo
