KRDC
What KRDC is
KRDC is a free Linux app for viewing or controlling another computer’s desktop session when that machine has a compatible server enabled. It connects through VNC, RDP, and SPICE protocol plugins, and the client and server can use different operating systems. KDE documents its use with Desktop Sharing (Krfb), a VNC server.
KRDC offers bookmarks and connection history, and can discover VNC services advertised on the local network through Zeroconf. RDP options include FreeRDP security modes NLA, TLS, RDP, and Ext, plus a configurable TLS security level. Users can configure a network proxy or gateway and set resolution, sound, shared media, and smartcard redirection. For SPICE sessions, dynamic resizing requires spice-vdagent in the guest, while clipboard exchange depends on guest support.
To connect, the remote server must be enabled and reachable, and its firewall must allow the required connection. KRDC can read basic connection details from an .rdp file, but does not import every setting available in other RDP clients. KDE lists Linux installation through AppStream-compatible stores or a distribution package manager, with a handbook, forum, and bug tracker for help.
Who it suits
KRDC suits Linux users who need to view or control remote desktop sessions over VNC, RDP, or SPICE. It is also relevant when the client and remote machine use different operating systems, provided the remote server is compatible and reachable.
What it does well

- Works across client and server operating systems.
- Provides bookmarks, connection history, and local VNC discovery.
- RDP settings include security modes, proxy, and gateway options.
- Can read basic connection details from an .rdp file.
What to know first
- Requires Linux and a compatible remote desktop server.
- The remote server must be enabled, reachable, and allowed through its firewall.
- .rdp import does not cover every setting supported by other RDP clients.
Limits

Getting started
- Install KRDC through an AppStream-compatible store or your Linux distribution’s package manager.
- Enable a compatible remote desktop server and ensure it is reachable through the firewall.
- Open KRDC and enter connection details, select a bookmark, or discover an advertised local VNC service.
- Configure protocol options such as RDP security, proxy, gateway, or display settings as needed.
- Connect to the remote desktop session.
Verdict
Choose KRDC if you need a free Linux client for VNC, RDP, or SPICE sessions and value its connection discovery and RDP controls. Look elsewhere if you need full import of settings from .rdp files or a client for a platform other than Linux.
