Remmina — The Complete Guide: Every Remote Connection on Linux in One Window

Remmina is an open-source (GNU GPL-2.0 or later) remote connection client for Linux. You keep a list of computers and servers in it and connect to each one with the protocol it needs. It is free for any use, commercial included, and available from distribution repositories, Flathub and the Snap Store.

What you get

RDP — connect to an office Windows workstation that runs the design software.
VNC — connect to computers and servers running a VNC server.
SSH — a terminal to a compute server in the same window.
SPICE and X2Go — access to virtual machines and Linux desktops.
Tabs and full screen — several connections open at once, with multi-monitor support.

Who it suits, and security

Remmina suits an engineer working on Linux who needs to reach Windows computers and servers. It is a client only: the target computer needs a running RDP or VNC server, and the program is available only for Linux. Never expose the target’s RDP or VNC directly to the internet — connect through a VPN or an SSH tunnel, and keep the passwords saved in the program behind a strong system password.
