LCC Hub IP address only shows localhost

[bakerstu]

Verified in JMRI 5.0+Rc441642522 running under Ubuntu 20.04.

After starting an LCC Hub (LCC->Start Hub), a window pops open that shows the "Hub IP address", but only shows "127.0.1.1:12021". Actually, this is not even the correct "localhost" because that would be 127.0.0.1. I'm not sure where 127.0.1.1 is actually coming from.

It would be much more valuable for the user if the window listed (all of) the host IP address(s) and port numbers similar to what the WiThrottle Server window does.

I'm not sure if this logic is resides in this repo or in the JMRI repo.

One more thing I noticed is that the title of the window is "OpenLCB" even though the connection type is LCC. This is otherwise fine, but it may confuse some users that don't know what OpenLCB is. Should it be changed it to "LCC/OpenLCB Hub Control"?

I will have a look around and see if I can improve things.

I believe that all 127.0.0.0/8 addresses work for localhost and connect to the loopback network device.

We should do the same thing as JMRI does for the withrottle window, which lists all local interfaces with their IP addresses.

The JMRI code for WiThrottle is near line 100 in java/src/jmri/jmrit/withrottle//UserInterface.java

Thanks, this is helpful.

The JMRI code that displays the hub address is in java/src/jmri/jmrix/openlcb/swing/hub/HubPane.java and the title is set in java/src/jmri/jmrix/openlcb/swing/hub/HubAction.java

Hi @dpharris I'm having a look at the Hub swing code in JMRI so can sort unless you're close?

I'm also thinking appending the connection / disconnection messages from the Hub into a scrollable list would be a nice mini update ;-)

Steve.

Go ahead. I have pulled my horns in at the moment for other changes.

Hi @bakerstu

There have been some tweaks in this area in JMRI 5.3.4 If you could confirm this now displays as expected?

Thanks, Steve.

[bobjacobsen]

Here's what it looks like now:

[icklesteve]

See https://github.com/JMRI/JMRI/pull/11902 which adds the LinkLocal connection, missed on previous update.

[dpharris]

Should we include a line that indicates that it is advertised as " openlcbcan.local."?

I don't think that's necessary. That is an internal name that does not necessarily need to be exposed to the user.
