VNCtalk Resources & Requirements¶
VNCtalk System Requirements for Clients¶
VNCtalk Webclient (Linux/ MacOS/ Win64)¶
The Hardware of your installed operating system must be capable to execute the Google Chrome/Chromium web-browser properly. If you can use YouTube, then your are ready for the VNCtalk Webclient as well. Current versions of Google-Chrome/Chromium, Firefox-ESR and Firefox Quantum are supported.
Mobile App¶
-
iOS 17 and newer
-
Android 11 and newer
For both mobile operating systems, you need to at least fulfill these hardware requirements:
- CPU: 2 Cores (1,8 GHz per Core)
- Memory: 2GB RAM
- Internal Storage: 1GB min free internal space.
Required Network-Bandwidth for video calls/conferencing¶
While for your upstream bandwidth 1MBit/s is the minimal requirement in order to use VNCtalk video conferencing properly, depending on the number of participants, you need to provide at least this amount of free downstream bandwidth in order to run VNCtalk properly on your Client:
| Number of participants | Required minimal bandwidth in Mbit/s (down) |
|---|---|
| 2 | 1.8 |
| 3 | 2.6 |
| 5 | 3.4 |
| n | 0.8(n-q)+1 |
This means, per AV-Stream at least 800kbit/s are required for proper functionality, if more is available, the quality of the stream is increased in resolution and bitrate depending on the participant's bandwidth abilities.
Required Network-Bandwidth for audio only calls/conferencing¶
While for your upstream bandwidth 256kBit/s is the minimal requirement in order to use VNCtalk audio conferencing properly, depending on the number of participants, you need to provide at least this amount of free downstream bandwidth in order to run VNCtalk properly on your Client:
| Number of participants | Required minimal bandwidth in kbit/s (down) |
|---|---|
| 2 | 256 |
| 3 | 320 |
| 5 | 448 |
| n | 64(n-1)+192 |
This means, per Audio-Stream at least 64kbit/s are required for proper functionality, if more is available, the quality of the stream is increased in resolution and bitrate depending on the participant's bandwidth abilities.
Required minimum Network-Bandwidth without A/V conferencing¶
To use the VNCtalk web client and mobile app features, except A/V-conferencing (Chat, etc.) you need at least GPRS/EDGE/ISDN connectivity in order to have fun with it.
VNCtalk System Requirements for Deployments¶
DNS-settings and IP requirements¶
Assuming, the domain for your VNCtalk installation will be yourdomain.tld, then
- a TLS-certificate, which covers the hostnames listed in column Public Hostname and
- the assignment local to public IPs
according to the table are required:
| Service | Public Hostname | Local IP | Public IP |
|---|---|---|---|
| VNCtalk | vnctalk.yourdomain.tld | Local-IP1 | Public-IP1 |
| VNCdirectory (user management) |
vncdirectory.yourdomain.tld | Local-IP1 | Public-IP1 |
| VNCidp | vncidp.yourdomain.tld | Local-IP1 | Public-IP1 |
| VNCpad | etherpad.yourdomain.tld | Local-IP1 | Public-IP1 |
| VNCchannels | wss-vncdirectory.yourdomain.tld | Local-IP1 | Public-IP1 |
| Fileshare | files.yourdomain.tld | Local-IP1 | Public-IP1 |
| XMPP | xmpp.yourdomain.tld | Local IP2 | Public-IP2 |
| Jitsi | meet.yourdomain.tld | Local IP3 | Public-IP3 |
| Stun | stun.yourdomain.tld | Local IP4 | Public-IP4 |
| Videobridge | - | Local IP5 | Public-IP5 |
In addition, for video conferencing, these two SRV-records are required as well:
_xmpp-server._tcp.yourdomain.tld in SRV 0 10 5269 xmpp.yourdomain.tld
_xmpp-server._tcp.conference.yourdomain.tld in SRV 0 10 5269 xmpp.yourdomain.tld
Mailrelay¶
In order to send eMail-Notifications and invitations to meetings to external users, a suitable mailrelay is required, that is properly configured for the domain yourdomain.tld, which we can setup for the VNClagoon applications.
