ftp connection fails if SYST command is unknown #5949
Description
1d1178e created the issue
cyberduck will abort connection to an ftp server if it doesn't know the SYST command, which is frequently disabled, and not necessary for proper operation. Here's a log from ftp://dl.free.fr (a server used to file exchange on the french ISP Free.fr) :

I had been using cyberduck to upload files there until recently, I believe it broke after version 4.x.
