Hi Gerhard,
Have a look at mikey protocol dissector in packet-mikey.c file.
The TCP port can be set using menu Edit/Preferences/MIKEY.
I think you can do the same thing for OPCUA protocol.
The code related to this is the following :
#define PORT_MIKEY 2269
static guint global_mikey_tcp_port = PORT_MIKEY;
void
proto_register_mikey(void)
{
...
/* Register our configuration options */
mikey_module = prefs_register_protocol(proto_mikey, proto_reg_handoff_mikey);
...
prefs_register_uint_preference(mikey_module, "tcp.port", "MIKEY TCP Port",
"Set the port for MIKEY messages (if other than the default of 2269)",
10, &global_mikey_tcp_port);
}
void
proto_reg_handoff_mikey(void)
{
static gboolean inited = FALSE;
...
static guint mikey_tcp_port;
if (!inited)
{
mikey_handle = new_create_dissector_handle(dissect_mikey, proto_mikey);
dissector_add_string("key_mgmt", "mikey", mikey_handle);
inited = TRUE;
}
else
{
...
dissector_delete("tcp.port", mikey_tcp_port, mikey_handle);
}
...
dissector_add("tcp.port", global_mikey_tcp_port, mikey_handle);
mikey_tcp_port = global_mikey_tcp_port;
}
I hope this will help you.
Regards
Philippe

Subject: [Wireshark-dev] OPCUA Update
Hi all,
the most OPC UA Specifications are released meanwhile.
Also Part 6 which describes the protocol.
So it was overdue to update the wireshark opcua plugin.
Really a lot changed since the last update: transport, security and application layer, so this is a big update.
I attached the patch that will update the code.
It's only tested on Linux, but buildbot while verify the other platforms anyway.
I also attached a sample capture file for fuzzy testing.
What is really missing is a configuration option in Edit->preferences
where you can configure the port. Default is port 4840,
which is also the registered port for OPCUA.
But a lot of servers will run on other ports, so a configuration option would be nice.
Maybe somebody can help at this point, because I have no clue about the
wireshark GUI stuff.
