MultiVNC

MultiVNC is a cross-platform Multicast-enabled VNC viewer based on LibVNCClient. The desktop version uses wxWidgets and runs on Unix, Mac OS X and Windows. There also is an Android version.

The roadmap for future developments regarding the project can be found here.

MultiVNC for Android

Features

• Support for most VNC encodings including Tight.
• TLS support, i.e. AnonTLS and VeNCrypt.
• Support for SSH-Tunnelling with password- and privkey-based authentication.
• UltraVNC Repeater support.
• Discovery of VNC servers advertising themselves via ZeroConf.
• Bookmarking of connections.
• Import and export of saved connections.
• Virtual mouse button controls with haptic feedback.
• Two-finger swipe gesture recognition.
• A super fast touchpad mode for local use.
• Hardware-accelerated OpenGL drawing and zooming.
• Supports server framebuffer resize.
• Copy&paste to and from Android.

MultiVNC for Desktop

Features

• Support for most encodings including Tight.
• TLS support, i.e. AnonTLS and VeNCrypt.
• Discovery of VNC servers advertising themselves via ZeroConf.
• Bookmarking of connections.
• Supports server framebuffer resize.
• Several connections with one viewer using tabs.
• Listen mode (Reverse VNC). Via tabs it's possible to listen for and serve multiple incoming connections.
• Record and replay of user input macros.
• Under X11, seamless control of the remote side by moving pointer over the (default upper) screen edge. Borrows heavily from x2vnc by Fredrik Hübinette [email protected], which in turn was based on ideas from x2x and code from vncviewer.
• Simple, loggable statistics.
• MulticastVNC ;-)

How to get it

To get bleeding-edge packages built from the master development branch, navigate to the list of CI runs, select the last successful one and download the wanted artifact.

How to build

The prerequisites:

• the usual c-compiler with headers and stuff
• wxWidgets dev package version >= 3.0
• zlib dev package
• libjpeg dev package

After cloning the repo, do

   git submodule init
   git submodule update

To build:

   mkdir build
   cd build
   cmake ..
   cmake --build .
   cpack

Depending on which OS you are on, you end up with a .deb, .dmg or .exe you can install.

MulticastVNC notes

You can get a modified libvncserver/libvncclient at https://github.com/LibVNC/libvncserver/tree/multicastvnc - this is the same library that MultiVNC uses internally.

Android: Code cleanup

There are some issues (related to style & formatting) that I can fix. I would like your feedback/suggestions before I start.

Issues

• Code formatting: Currently there are different styles of formatting (eg. tab vs space) used. We can follow a consistent style.
• Missing license: Some files are missing license headers. We should fix it.

Why fix it

• Increased readability
• Reduced maintenance efforts
• Easy on-boarding for new contributors

remove top right options overlay

there should be an option to remove the top right menu overlay

VNC

Crashes on startup on Arch Linux

I have built a package based on multivnc-git, using an updated PKGBUILD:

https://gist.github.com/kode54/c03b9a9e8b3203f222ee

And the resulting application crashes with this stderr output:

Function key on Gemini PDA Android device broken, can't enter dashes, underscores and more

When using multivnc on the Gemini PDA Android phone (which has a hardware keyboard where some different key characters are accessed via shift, but some others also via an additional function key) the function key doesn't work inside the vnc session, making it impossible to enter dashes, underscores and many other vital keys. It works fine in all other apps including e.g. termux

Huavei 10 mate lite Capslock state detection problem

Dear specialists, I Am using yours app with Archlinux Aarch 64 which run by using Termux and Android device. Sure, Multivnc run on normal Android phone. I have issues with The Capslock key detection state. Orca screen reader uses XKB protocol to get information about pressed keys. For example. When I turn Capslock on, I can correctly type big letters. But Orca do not detect if Capslock have been pressed and its state. On or off. This problem is independent which Hardware keyboard model will I use. Orca can not also correctly detect if I have pressed left ALT or right ALT key. Orca speak left ALT even I press right ALT. The most annoing issue is The fact, that I can not control Orca navigation system. Because if Orca do not detect CAPSLOCK state, it can not react on key combination CAPSLOCk and some letter such as u, j or l.
Do you think, that there is some chance to find out The ccause of this issue?
The problem is really in VNC client app. May be, that Orca need to get more specific more exact info about keys. The question is, if is itpossible to develop such code inside yours app, which would inform this screen reader about The state of CAPSLOCk key.
Sure. Orca have been developed for A situation, where user uses it iwth standard Linux not controlled by using VNC protocol.
Any help will be very welcomed.
Thank you very much for yours time.

Cannot build using autogen.sh

The autogen.sh script does not work, because it can't find the config.h.in file, due to .gitignore restrictions.

Phone vs tablet behaviour

Hello, I'm a long time user of MultiVNC and I like it a lot. I'm trying to use it now in a tablet with a big eInk screen. There seems to be different behaviors between this device and a phone, and I'm not sure that you are aware of it, since I couldn't find anything about it in the help of the app or here in the repo. Both devices are running MultiVNC 1.8.9, the tablet running Android 9, the phone running LineageOS 16 (Android 9).

From the phone I'm moving the mouse by swapping in the screen. Taps don't work. Mouse clicks are done with the bottom screen buttons. If Toggle Mouse Buttons is disabled, then taps works, where one tap is a left click, and two taps is a right click. In the Tablet, mouse movement by swipe is not working, because swipe seems to be interpreted as a multiple tap, and tap is interpreted as a left click, which I think is fine, since with a big screen is easy to tap where you want to click. I couldn't find a way to do a right click without toggling the mouse buttons.

In my phone I am able to scroll by two finger swap. In the tablet I can't do that. There's also a problem with the zoom. In my phone I long press to show the zoom +, keyboard and zoom - icons at top, but in the tablet long press is like a tap, like a mouse click, so is not showing those buttons.

No menu on Samsung tab A

If you'd like to put out an incentive for fixing this bug, you can do so at https://issuehunt.io/r/bk138/multivnc?tab=idle

Is your bug report about the Desktop Multivnc or the Mobile MultiVNC?

• Desktop (wxWidgets) or Mobile (Android): Android 7.1.1

Describe the bug

Samsung galaxy tab a, connects to raspberry pi3, but the hamburger menu does not open. It makes an audible click, but I expect a menu to open with keybd mode, exit, etc.

• Android version: 7.1.1
• Installed from Play Store or F-Droid: f-droid

Doesn't work with turbo vnc

Version 1.7.9 f-droid
Show error when connecting Unknown RFB message type 145
Works with other vnc servers.
Also tight vnc client connects just fine

Submit app to F-Droid

It would be great if this app was available via the F-Droid repository (https://f-droid.org/) in addition to Google Play Store. This is useful for people who don't like to use Google Play Store in general.

Also, F-Droid creates an archive of previous versions, something that Google Play does not do. This can be useful if there is a bug in a new version, allowing the user to revert to an older one.

change how jmdns is integrated

Right now, we have jmdns running in a background service in order to have mdns discovery decoupled from the mainacitvitiies on-rotate re-create(). Starting from android Oreo, this should probably be a ForegroundService (with an ugly notification) or something else...

Android (Multi-touch support)

Can't rotate Android app

The orientation is fixed horizontal. It should either rotate when the device is rotated, or else be a setting per connection.

Feature request: Change of default controls for buttonless mode

If you'd like to put out an incentive for implementing this feature, you can do so at https://issuehunt.io/r/bk138/multivnc?tab=idle

Is your feature request about the Desktop Multivnc or the Mobile MultiVNC?

• Desktop (wxWidgets) or Mobile (Android): Mobile
• If Mobile, installed from Play Store or F-Droid: F-Droid

Is your feature request related to a problem? Please describe.

There are a few controls I'd like to be able to configure. I'd like to be able to:

1. Make a long press gesture send the right click signal (rather than open the zoom controls)
2. Make a double tap gesture send a double click
3. Make a double tap and hold gesture (i.e. tap, release, tap and hold on the second tap) send a click and hold signal (i.e. click and drag)

These controls are akin to the controls for the VNC Viewer app on the playstore. I prefer these controls to MultiVNC's default controls. In fact, I only keep that closed source app installed for those controls.

Describe the solution you'd like

Rather than impose my preference on all users of MultiVNC, it would be great if users could configure their preferred controls. Maybe a menu to configure key-value pairs of "gesture:signal"

Describe alternatives you've considered

What happened to x11vnc-multiptr

Hi,

sorry for creating the issue here, it is not really related.
However, I am looking for a repository which existed once and doesn't anymore: x11vnc-multiptr

I like to use VNC for remote pair programming.
I found this screenshot which looks really awesome.
https://media-cdn.ubuntu-de.org/forum/attachments/23/19/2448200-vnx-mpx-shot.jpg

Can you give a reason why the repo is offline now or maybe even provide a copy of the sources?

Best regards
Andreas

Android: Mixed line terminators

Currently following files uses CRLF line terminators:

• COLORMODEL.java
• ColorModel256.java
• ColorModel64.java
• ColorModel8.java
• Utils.java

All other files use LF. We should use same for these files to be consistent.
Also, git (with default config) converts CRLF to LF when committing. Then small changes appears as if the whole file is changed.

I can submit a PR but GitHub also says that every line is changed.

Keyboard doesnt work at all with UserLAnd

Describe the bug
I set up a UserLAnd install on an Android 9 (LineageOS) phone. UserLAnd works fine in combination with MultiVNC. I can connect, move the mouse, use the onscreen mouse buttons. However, if I toggle keyboard the keyboard pops up but I cannot press any key on the keyboard. It's there but it doesnt work. Instead if I press a button those touches go right 'through' the keyboard and are recognized by the underlying 'virtual mouse'.

To Reproduce

1. Install MultiVNC
2. Install UserLAnd
3. Connect to a VNC session
4. Press the menu button and then toggle keyboard
5. Keyboard pops up but doesnt respond to any input.

Expected Behavior
The keyboard should respond to the input via touch.

For the Desktop Version (please complete the following information):
OS: Ubuntu@UserLAnd
XORG: The one that comes with UserLAnd

For the Mobile Version (please complete the following information):
Android 9 (LineageOS 16)

Additional information
Why does that seem to be a MultiVNC bug? Tried realVNC with the same setup, the keyboard there works as it should.

Readme or wiki file: android activities list

With the growing trend of Termux based Linux environments and scripts emerging from this, it would be great to have an on-hand list of supported activities for your application.

This comes in handy to help initialize, populate or start VNC sessions directly from Termux or any other capable application/activity.

Thank you for your consideration!

Is there a binary release for macOS?

"null" after connecting an external keyboard

The problem appears if you connect (or disconnect) external keyboard to a device while MultiVNC is connected to a session. It disconnects from session with error message: "VNC connection failed! null". After reconnecting everything works as expected but if you disconnect keyboard (or just turn off the Bluetooth) — it goes the same way.

Is your feature request related to a problem? Please describe.

The currect zoom is a bit "jerky". It sometimes doesn't register and stops zooming in/out in the middle of a pinch, resulting in the user doing many pinches to get the desired zoom. I tested this with different devices to make sure it was a specific device quirk.

Describe the solution you'd like

A smoother zoom that is more like the zoom experienced in the popular web browsing apps (firefox, chrome, etc). It currently feels like the zoom stops when the fingers stop moving. It might be better to stop the zoom when one or both fingers are lifted

Describe alternatives you've considered

add ability to save passwords

Idea is to employ https://docs.wxwidgets.org/trunk/classwx_secret_store.html for storing the credentials.

• a) tied to bookmarks

  • pro: when saving a bookmark (host:port), we know the credentials where right cause the connection is up
  • con: we have to store credentials for the connection in-memory until the user saves a bookmark

• b) tied to server's host:port

  • pro: can store creds right away, no need to persist them in-memory, key could be host:port
  • con: at the time of get_creds(), we dunno if they were actually ok
    • delete them after conn fail?

• what about servers hosting multiple accounts?

Feature Request: send right clicks when using a hardware mouse

Is your feature request about the Desktop Multivnc or the Mobile MultiVNC?

• Desktop (wxWidgets)
• [ X ] Mobile (Android)

Is your feature request related to a problem? Please describe.
I sometimes use a USB mouse connected to my phone using an USB OTG cable when I need more clicking precision than the touchscreen offers. Currently the right click button sends the same signal as the Android Back button, and MultiVNC asks me "Are you sure you want to disconnect?". It would be great if MultiVNC could interpret a mouse right right click and then send then right click signal like it does when tapping MultiVNC's on screen/virtual mouse button.

Describe the solution you'd like
If a hardware right click is used in the MultiVNC (and the VNC server OS supports it), then a context menu should open. Ideally it would act just like the on-screen right mouse button that MultiVNC already has.

Too much wasted space for key combo toolbar on Android

As a general principle, UI bars waste the least useful space when placed across the smaller dimension of the screen. This toolbar is taking away a lot of the screen. It should be possible to hide, and to put onto the smaller dimension (which should be the default).

Is this software support multicast udp?

Too many bookmarks due to automatic bookmarking, launched from UserLAnd

Describe the bug
Using MultiVNC in combination with UserLAnd. Every time I log into a desktop session a new bookmark is created within MultiVNC. Those add up eventually.

Could you make automatic bookmarking optional? Otherwise those get too much eventually. Had to delete 25 or so bookmarks one by one.

Thanks.

To Reproduce

1. Install MultiVNC
2. Install UserLAnd
3. Set up desktop inside UserLAnd
4. Connect to desktop via UserLAnd app
5. Bookmark is created in MultiVNC

Expected Behavior
No bookmark is created within MultiVNC

Android: VNCConn Refactoring

VNCConn refactoring Proposal (as per #15 ):

Extract progress dialog & fatal error alert

• Move ProgressDialog and error dialogs to VncCanvasActivity.
• VNCConn will expose an observer interface which will be implemented by VncCanvasActivity.
• VNCConn will publish updates through the observer.

This will allow the activity to attach/detach to VNCConn without affecting its operation. It also simplifies VNCConn and makes it UI agnostic.

Move Credential dialog

• Move credential dialog from VncCanvas to VncCanvasActivity .
• VNCConn will notify the activity through observer.
• Activity will display the dialog.

In future when we implement rotation, it will allow the activity to save the credential request in its ViewModel to handle restarts. It will also reduces the direct dependency on VncCanvas.

Extract FrameBuffer

• Create a new 'FrameBuffer' class.
• Move bitmap data from VNCConn to FrameBuffer
• Move pointer position from VncCanvas to FrameBuffor
• Attach FrameBuffer with VncCanvas and pass a reference to VNCConn

Now we will be able to generate a new FrameBuffer whenever required. It also enables VNCConn to function without any fame buffer (time between activity restarts). See figure below.

---

After this refactoring we should be able to put VNCConn in a ViewModel which will persist across activity restarts. Now we can implement whichever strategy (Restarts vs No restart) we choose.

For Restarts:

We detach from VNCConn inside onStop() and attach again in onStart() of new activity

For No restart

We can simply generate a new FrameBuffer for the resized VncCanvas and pass it to VNCConn

Data flow

---

Future/Optional
These are few ideas we can try after refactoring is complete.

• Now that all dialogs/alerts are handled by VncCanvasActivity, we can unify them into one custom dialog. It will allow us to replace ProgressDialog which is deprecated and it will integrate better with ViewModel.
• Rename ServerToClientThread to ReceiverThread & ClientToServerThread to SenderThread.

Let me know if you have any suggestion or something is wrong.
Thanks.
