From FyshyWyky

The FTP service on river.fysh.org no longer allows connections from the general Internet. The only reason to keep the service at all is that at least on user makes use of it when installing/upgrading software on our web server. As such access is only available via localhost and the fysh server IPs.

Users wishing to transfer files onto river.fysh.org are advised to look into alternatives such as [wikipedia:Secure copy|SCP]] or SFTP).
