command line calling with arguments?

[Ted Serreyn]

Is it possible to pass the host/port information along on the mac aspice/bVnc clients?  or maybe support spice/VNC URLs?

I am tyring to use the spice and vnc viewers to get to consoles on GNS3.

currently VNC viewer is defined like this (using RealVNC viewer):

"/Applications/VNC Viewer.app/Contents/MacOS/vncviewer" %h:%p

and spice as (not working):

/Applications/RemoteViewer.app/Contents/MacOS/RemoteViewer spice://{host}:{port}

Hi Ted,

Here are the options available on iOS/MacOS:

- Launch aSPICE on the commandline with a console.vv file (you can just double-click it, or you can pass it as the first and only parameter). Console.vv files are the config that Proxmox, OpenNebula, oVirt, and RH Enterprise Virtualization outputs. bVNC does not support "VNC files" at the moment.

- Launch both bVNC and aSPICE with a "Universal URL".

The Universal URL has all these parameters

(vnc|spice)://HOST:PORT?connectionName="Nickname of the connection to launch or create"

There are a couple more parameters that are for upcoming functionality, namely requiresVpn, vpnUriScheme, and externalId. I can go into details for those if they are relevant.

Relevant part of the code:

https://gitlab.com/iiordanov/remote-desktop-clients-ios/-/blob/master/bVNC/app/main/SceneDelegate.swift?ref_type=heads#L138

On Android there are ton more parameters for the URI intent that the apps support, but I guess you're not interested in that at the moment.

Does that help?

Cheers!

Hi Ted,

Unfortunately that's not how one asks an application to open a "Universal URL" on MacOS / iOS.

One way that would work is to have a web page with links like:

                <a href="vnc://1.2.3.4:5900/?ConnectionName=test">VNC connection</a>
                <br>
                <a href="spice://2.3.4.5:5902/?ConnectionName=test">SPICE connection</a>

If that's not viable in your scenario, we'd need to implement URL support on the CLI.

Ok so if I understand correctly this should work.

/Applications/bVNC.app/Contents/MacOS/bVNC vnc://192.168.168.44:5907

 

However it does not appear to work.

Application opens, but does not seem to go to the defined ip address (substituted different ip)

OK, I found how to open all manner of URLs from the CLI on a Mac.

Try these:

open "vnc://1.2.3.4:5900/?ConnectionName=test"

open "spice://2.3.4.5:5900/?ConnectionName=test"

Cheers!

yeah that’s what I was afraid of.

I’m going to see if I can use the built in URL mapping rather than the defined applications, but I’m not sure that is going to be feasible.

Even simple passing the host and port would be enough to get this to work from a basic step.   I’ll try to dig into the code a bit to see what it would take.

Oh, I really like this osascript solution!

In version 41 of the apps, I am actually going to add URIs that start with the name of the apps (bvnc, ardp, aspice). So you can use that instead once they are out. But for the moment something like this does it.

osascript -e 'tell application "bVNC"'  -e '  open location "vnc://10.10.220.222.44:5907/?ConnectionName=TEST"' -e 'end tell'

And yes, you have to specify ConnectionName.

Cheers!

Yeah not sure why, but vnc url opens the mac screen sharing application rather than bVNC.  Trying to figure out how apple handles this registration for urls rather than file open-with.

Spice url does seem to open the application, so I’ll need to play with it to see if spice consoles can be used instead of vnc.

 

 

Thought I had a solution, but looks like bVNC still didn’t like it.

I can use applescript to “tell” the application to open the URL.  And it doesn’t seem to handle it correctly.

 

Tried applescript:

osascript -e 'tell application "bVNC"'  -e '  open location "vnc://10.220.222.44:5907"' -e 'end tell'

 

tried direct open (after registering bVNC as application for vnc:// url)

open vnc://10.220.222.44:5907

 

You can use SwiftDefaultApps to register the URL for most URL to include ssh, telnet, spice, vnc.
