Important: Remote Desktop uses two-factor authentication, but you won't get a reminder about that on the screen when you log in. When you log in to Remote Desktop, you must check the phone to confirm the login in Microsoft Authenticator (with Remote Desktop you cannot confirm login with anything other than Authenticator).
RDP with FreeRDP
Install FreeRDP
FreeRDP is a free and open implementation of the RDP protocol. Install it on your computer as normal.
Ubuntu:
$ sudo apt-get install freerdp-x11
Fedora and RedHat:
$ sudo yum install freerdp
To connect
All RDP must go through the gateway rds-portal.uio.no. Use your normal UiO password. You will be asked for your password twice; one time for the portal and one time for the server you want to connect to (in the example it is: win.uio.no).
Some Linux distributions have newer versions of FreeRDP in their packet handler. In version 1.0.2 you can connect using:
$ xfreerdp -u brukernavn -g rds-portal.uio.no win.uio.no
For newer versions you must use the following (/gt:rpc is for using correct authetication for rds-portal.uio.no)
$ xfreerdp /u:brukernavn /g:rds-portal.uio.no /v:win.uio.no /gt:rpc
