Question: Is it possible to run both 1.0 and 1.1+ dissectors at the same time?

[owens-bill]

I have been using the CPqD dissector and it works well on my Mac with Wireshark 1.8.3 from MacPorts. However, I can't have it installed at the same time as the 1.0 dissector; Wireshark complains:

08:14:36 Err Duplicate protocol name "OpenFlow Protocol"! This might be caused by an inappropriate plugin or a development error.

Is there a workaround for this? The two plugins have different filenames, but it looks like they're contending for the place in the list of protocols.

Thanks,
Bill.

Hi Bill,

I have had this problem too, and I haven't really looked into how to solve it. What I do for now is manually choose the file in the plugins directory whenever I want to use a specific version. This dissector is based on ng-of-dissector (https://bitbucket.org/barnstorm/ng-of-dissector), and this issue affects it too.

I will try to make them both work together, so I'll leave this issue open.

Hi Bill and allanv,

I solved the problem. It was twice .so file on plugins directory as openflow.so.

sudo rm -f /usr/lib/wireshark/libwireshark1/plugins/openflow.so

Best regards.

I met the same problem. How you guys solve this problem? Kursatgol, your method does not work for me. It will show Couldn't load module /home/guest/.wireshark/plugins/openflow.so /home/guest/.wireshark/plugins/openflow.so undefined symbol:try_val_to_str.

Hi zhangwei1984,

I think you have not this specific file openflow.so. Maybe there is a problem on your openflow patching with wireshark.

Best regards.
