    error message can't open data connection

    what does it mean...
    how do I fix that?

    The first thing I'd try is changing the setting of the "Use passive mode transfers (PASV)" box in the Firewall section of Fetch Preferences. If that doesn't help could you post the contents of the Fetch Transcript window after you see the error? Choose "Fetch Transcript" from the Window menu to open the window.

    Thanks,

    I am having the same problem/message when using Fetch to connecti to certain servers, but am able to get through on others. Below is the transcript of my latest attempt:

    I am on a MAC OS 10.3.2 using Fetch 4.0.3. Have tried turning PASV on and off.

    Data connection problems are usually caused by a firewall or router problem on one end of the connection or the other. A blockage on the Mac's side can usually be worked around by using PASV; a blockage on the server side can usually be worked around by unchecking PASV. But if things are blocked on both ends you might be stuck.

    ftp.fetchsoftworks.com is a server you can log into (leaving the User ID and Password fields blank), and it does not have any firewall in front of it. Can you login to ftp.fetchsoftworks.com with PASV turned off? If so, I'd try connecting to your server with the same setting, and post the transcript if it doesn't work. If not, I'd try to figure out what the problem is. Do you have any firewall software running on your computer?

    Thanks,

    Thanks Jim for your thorough explanation and troubleshooting steps.

    I was able to get through by turning off the Firewall in System Preferences/Sharing as well as turning off PASV in System Preferences/Network/Proxies and in Fetch.

    Seems to working with other servers too.
