TightVNC — Old but Useful Remote Desktop
What it is
TightVNC is one of those tools that’s been around for ages. It’s based on the VNC protocol and was made to be small and free. Nothing fancy, just a way to see and control another desktop. Many admins used it in the 2000s and some still keep it in their toolbox.
How it works
Setup is simple: install the server on the machine you want to reach, connect with the viewer from another. It streams the desktop over RFB with TightVNC’s own compression to save bandwidth. Works on Windows and Linux. Since it follows the VNC standard, it can talk to other VNC-compatible tools.
Technical profile
Area | Details |
Platforms | Windows, Linux |
Protocol | RFB (VNC) |
Features | Remote control, file transfer (Windows), cross-platform |
Auth | Password-based |
Security | Weak alone, better with VPN or SSH |
License | GPL, free |
Why it’s still around
Runs on old hardware, very lightweight.
Free and open, no licenses.
Plays nice with other VNC tools.
Quick fix when you just need access without big installs.
Common use
– Small offices with a couple of PCs.
– Home labs, test benches.
– Connecting to legacy machines.
– Training rooms where cost matters more than speed.
Security notes
By itself, not safe. No strong encryption. Admins usually tunnel it through SSH or VPN. Best not to expose it directly online.
Weak spots
Not actively developed like TigerVNC.
Struggles with heavy graphics.
No modern features (2FA, persistence).
Security needs extra layers.
