Server Response: Can't Open Data Connection (10 posts)

    After switching to a Mac, I am using Fetch to try to access an FTP server that I could previously access on a Dell laptop. I go to this particular server to retrieve video files from a local TV station.

    I seem to make a connection to their server, but I get a message that reads:

    Server Response: Can't open data connection

    After I click that window closed, it says I am connected, but I never see any files, directories, etc.

    I unchecked PASV in Firewall Preferences but that has only caused the process to stall at "Getting File List..." under status. That poor little dog has run like 20 miles. :-) When I hit Stop, it says I am connected, but again, no files are visible.

    I am working with an IT person at the TV station and we're not sure where to go from here. Any suggestions?

    If you are running OS X make sure that the OS X firewall is turned off (in the Sharing pane of System Preferences).

    If that is not the answer could you choose "Fetch Transcript" from the Window menu when the dog is running and post the contents of that window?

    Here is the Fetch Transcript from when I try to access this FTP site:

    According to the transcript "Use passive mode transfers (PASV)" is still checked in the Firewall pane of Fetch Preferences. Could you try with that unchecked?

    You might also try Fetch 5, which you can download from http://fetchsoftworks.com. Your serial number will work with Fetch 5, so it will be a free upgrade.

    Thanks,

    Here's the transcript with PASV unchecked. Like I'd mentioned before, it stalls at "Getting File List" under "Status."

    And the OS X firewall is turned off? To check, choose System Preferences... from the Apple menu, click on the Sharing icon, and then on the Firewall tab.

    Thanks,

    Firewall is off.

    There's an entry on the transcript that says:

    "MACB ENABLE
    500 'MACB ENABLE': command not understood"

    What does that mean? "Not understood" infers to me that the two computers did not talk about something important. Could their FTP server not be set up right to enable Mac access?

    Most FTP servers do not support MACB, so that isn't a problem. Fetch is just checking in case the server is one of the few that does support MacBinary transfers.

    Do you have any other firewall or internet security software installed?

    Can you connect to ftp.fetchsoftworks.com and get a file list there? Leave the User ID and Password fields blank. If that does not work, could you post a transcript?

    Thanks,

    Yes, I got the file list there just fine. Quick as a whistle. Does that isolate the problem on their end?

    Posted 8 years ago #

    Yes, that suggests a problem on their end. But I am puzzled; it is unusual for active (non-passive) data connections to work for one server and not another.
