Cannot connect to RDP over SSH to multiple hosts

I have several RDP over SSH connections defined in Remmina. When I connect to one, the fingerprint is stored in .freerdp/known_hosts – but for the “host” 127.0.0.1, due to the SSH tunnel.

When I try to connect to the next RDP over SSH connection, this fails with “Unable to connect to RDP server 127.0.0.1”, due to the record in known_hosts.

Seems like Remmina should allow several RDP to localhost to avoid this.

Workaround: Remove ~/.freerdp/known_hosts between each connection.

Permanent workardound:

rm .freerdp/known_hosts && ln -s /dev/null .freerdp/known_hosts
