NuviraHub 0.15.0

Download

• Windows
  • nuvira-setup.exe: installer (unattended access, Start menu, uninstall from Windows settings).
  • nuvira.exe: the same program, runs without installing; it can install itself from Settings.
  • nuvira-update-0.15.0.zip: the signed update, for your own server: unpack it into the server's updates folder (how).
• Linux (64-bit; Debian 12, Ubuntu 24.04, Mint 22, Fedora 40 or later)
  • nuvira-linux-x64.deb: Ubuntu, Debian, Mint (sudo apt install ./nuvira-linux-x64.deb).
  • nuvira-linux-x64.rpm: Fedora (sudo dnf install ./nuvira-linux-x64.rpm).
  • nuvira-linux-x64.tar.gz: other distributions, or without sudo: extract it and run ./install.sh (installs into ~/.local).

With no server set the app uses the free NuviraHub public server (connect.nuvirahub.dev, terms, privacy); to use your own, see the server image.

Linux: also X11 sessions can be controlled

• Linux Mint, Xfce, MATE and the other desktops with an X11 session now show ID and password and can be controlled: screen (with the cursor), mouse, keyboard, wheel, clipboard, files. No permission dialog on X11. First version: tested on Linux Mint 22.3 Cinnamon.
• With Wayland (Ubuntu, Fedora) it works as in 0.14.0.
• Not yet: unattended access, which is Windows only for now.

Session toolbar

• Ctrl+Alt+Del is shown only towards Windows computers: on Linux and macOS it does nothing.

Updates are also signed with the NuviraHub release key and checked by the app. SHA-256 of the files in SHA256SUMS.txt.

Linux: this computer can be controlled (Wayland)

• With a Wayland session (the default on Ubuntu and Fedora) the app shows ID and password, and the Linux computer can be controlled: screen, mouse, keyboard, clipboard (text and images) and files, through the system's remote desktop portal and PipeWire. Tested with GNOME.
• The first time, after NuviraHub's confirmation, the system asks the person at the computer to allow remote control; the permission is remembered for later sessions, until it is revoked in the system settings.
• When the screen locks the system stops the sharing: the image resumes by itself once the screen is unlocked. If it is locked when the session starts, or the person does not allow it, the viewer says so.
• Received files go to the user's downloads folder ("Scaricati" on an Italian desktop).
• Not yet: X11 sessions (they still only control other computers) and unattended access, which is Windows only for now. Details.
• The packages are now built on Debian 12: Ubuntu 22.04 and Mint 21 are no longer supported (their PipeWire is too old); 0.13.0 keeps working there.

  • nuvira-linux-x64.tar.gz: other distributions, or without sudo: extract it and run ./install.sh (installs into ~/.local).

With no server set the app uses the free NuviraHub public server (connect.nuvirahub.dev, terms, privacy); to use your own, see the server image.

Linux: control other computers

• The app runs on Linux, with X11 or Wayland: ID, address book, connecting, the session window with its toolbar. The Linux computer itself cannot be controlled remotely yet: the app says so (details).
• Automatic updates are for Windows only for now: on Linux, install the new package.

Session window

• While the remote computer has not accepted yet, the window says so ("Waiting for the person at the remote computer to accept…") instead of staying black.
• Its own icon (an N inside a screen), so it is not mistaken for the app in the taskbar, on Windows and on Linux.

Code-signed

• nuvira.exe, nuvira-setup.exe and the automatic update are now signed with a Certum Open Source code signing certificate ("Open Source Developer Alessandro Blason"), with a timestamp. Windows and antivirus software can see who published the program: unsigned, an antivirus took the installation of the service for malware.
• The certificate is new: Windows SmartScreen may still warn the first times ("More info" → "Run anyway") until it has built up reputation.
• Customised installers of NuviraHub Pro keep the signature valid.

Video as datagrams (experimental, off by default)

• One parity shard instead of two while no losses are measured: on a saturated 2 Mbit/s link the median latency went from 125–170 to 76–83 ms.

NuviraHub 0.12.9

Download

• nuvira-setup.exe: installer (unattended access, Start menu, uninstall from Windows settings).

No more freezes when the quality adapts

• Changing the video bitrate or size used to restart the hardware encoder, which froze the image for 0.8–1.3 s every time (at the start of each session, and at every bitrate change on an unstable link). The encoder is now reconfigured in a few milliseconds. A clean session through the relay: 3 freezes → none, 53 → 57 fps. Checked with Intel Iris, UHD 620, HD 2500 and NVIDIA RTX 4060 Ti.

Smoother on slow and congested links

• The adaptive bitrate no longer raises the quality while the screen hardly moves, nor climbs back past the rate at which the link filled up. Simulated 2 Mbit/s link with 40 ms delay: the 95th percentile of the latency went from about 1 s to 150–250 ms.
• At the start on a slow link the bitrate now comes down far enough to empty the queue that formed: the image catches up in about 3 s instead of 6–10.
• Keyframes asked by the viewer are limited to one a second.

NuviraHub 0.12.8

Download

• nuvira-setup.exe: installer (unattended access, Start menu, uninstall from Windows settings).
• nuvira.exe: the same program, runs without installing; it can install itself from Settings.

With no server set the app uses the free NuviraHub public server (connect.nuvirahub.dev, terms, privacy); to use your own, see the server image.

A stopped service is shown, and can be started again

• When the NuviraHub service is stopped, the app shows it (red dot, "this PC is not reachable") with a button that starts it again, first updating it if it is older than the app (asks for administrator rights).

Updates that stop halfway no longer leave the PC unreachable

• The service keeps a backup of its program once it has run well; if an update stops halfway and the program is missing, a system task puts the previous version back and starts the service within about a minute.
• Found with Kaspersky Anti-Ransomware Tool, which took the unsigned program installing the service for malware and deleted the files it had written. The program will be code-signed in a coming release; until then such an antivirus may still block the update itself, but the PC stays reachable on the previous version.
• The Start menu shortcut is created by the program itself instead of a PowerShell script.

The program is not code-signed yet: Windows SmartScreen may warn the first time ("More info" → "Run anyway"). Updates are signed with the NuviraHub release key and checked by the app. SHA-256 of the files in SHA256SUMS.txt.

NuviraHub 0.12.4

Download

• nuvira-setup.exe: installer (unattended access, Start menu, uninstall from Windows settings).
• nuvira.exe: the same program, runs without installing; it can install itself from Settings.

With no server set the app uses the free NuviraHub public server (connect.nuvirahub.dev, terms, privacy); to use your own, see the server image.

Faster sessions

• Intel Quick Sync no longer stops at about 32 fps: the encoder waited for the coarse Windows timer. Real screen between two PCs on the LAN: 28 → 52 fps, median latency 37 → 27 ms, 95th percentile 61 → 40 ms.
• The remote PC encodes at the size of the viewer's window: a 4K screen seen in a 1280×720 window goes from 23 to 40 fps, latency 85 → 39 ms (and less bandwidth). "Actual size" still sends every pixel.
• The viewer no longer falls back to Windows' software renderer on old graphics cards (1.5 → 47 fps there).

Fixes

• Automatic updates of the service can no longer leave the PC unreachable: a system task starts the service again if the update stops halfway, starting is retried, and update.log records the time of each step.
• With the service installed, the server chosen in Settings now applies to the service (asks for administrator rights); the status dot no longer stays yellow after clearing the server name.
• Settings icon is now a gear.
