Wireshark · Wireshark-bugs: [Wireshark-bugs] [Bug 10805] Websocket dissector does not find subdissector correctly from port_subd

[bugzilla-daemon@xxxxxxxxxxxxx]

Comment # 11 on bug 10805 from Yang Liu

Hi Matin,

Thanks for looking into this issue. I uploaded captured packets and screenshots
for using released and modified wireshark to dissector my packets.

Here is the code in my dissector proto_reg_handoff_viewvc(void) function.

    viewvc_handle = new_register_dissector("viewvc", dissect_viewvc,
proto_viewvc);
    dissector_add_uint("ws.port", VIEWVC_PORT, viewvc_handle);
