    Hello,

    I am working with a client that is having some trouble FTP-ing using Fetch on a Mac. He is FTP-ing to a Windows server. The user gets the error message listed in the subject of this post.

    Here is the contents of the Fetch Transcript Window:

    Please advise.

    My first suggestion would be to check the "Use passive mode transfers (PASV) box in the Firewall section of Fetch Preferences. Does that help?

    Thanks,

    It kind of helps. This all started when the FTP host locked down the FTP server. All FTP users had to turn off Passive (or PASV) FTP in their FTP clients. We have turned off the PASV FTP but we get this problem now.

    Please advise.

    It looks like the client is going through a Network Address Translation (NAT) device (such as a router or wireless base station) that is translating the PORT command (when PASV is not checked). Unfortunately it is corrupting the following command (LIST) so that all the server sees is "T". So the options I can see are to fix or replace this NAT device, or get the server to allow PASV. Fixing the NAT device might involve getting a new version of the firmware; you'd have to contact the vendor to see what the options are.

    Thanks,
