    I've been following the posts, and can't find the solution to my problem.

    I have been using Fetch for years without any problem, and I'm currently using Fetch 4.0.1. This is the first time I've had this problem.

    When I connect to the server with PASV turned off, I get the error "Server Response: Can't build data connection: connection refused." The error comes up right away.

    Here is the log:
    Connecting to ftp.wiznet.ca port 21 (6/15/03 10:17:42 PM)

    200 PORT command successful.
    LIST
    425 Can't build data connection: Connection refused.
    ftp_list: -30000 (state == GETTING_LIST)

    If I try to connect with PASV turned on, it says it's getting the file list, then it eventually times out and gives me this error message: "server response: can't open data connection". Here is the log:

    I don't have any problem connecting to the server using CuteFTP on a PC. I also tried downloading a different FTP program for the Mac (it wasn't anywhere near as good as Fetch!), and got the same error as Fetch.

    In both cases (PASV on and off) I seem to stay connected to the server, and be able to navigate top level directories, just not see an subdirectories or files. Please help - this is driving me nuts!

    First of all I would recommend using Fetch 4.0.3; it fixes a bug in non-PASV mode on OS X. You can download 4.0.3 from http://fetchsoftworks.com

    My best guess is that you want to uncheck the "Use passive mode transfers (PASV)" box; it looks like the server is behind a Network Address Translation (NAT) device, and they can keep PASV mode from working.

    Thanks Jim. I downloaded 4.0.3 but I still have the same problem. When I unchecked PASV I get:
    LIST
    425 Can't build data connection: Connection refused.
    ftp_list: -30000 (state == GETTING_LIST)

    and when PASV is checked it tries for a very long time, then I get:
    LIST
    425 Can't open data connection.
    ftp_list: -30000 (state == GETTING_LIST)

    Am I missing something? There's only the one place to check/uncheck the PASV, right? In the Firewall part of preference?

    Is there any significance between "building" a data connection and "opening" a data connection?

    Thanks!!

    That's correct, there's only one place to change the PASV setting.

    You mentioned that CuteFTP can connect from the same network. I would be interested in seeing a transcript from CuteFTP, if you can get that.

    Thanks,

    Hi Jim

    I'm out of town (actually at the end of a dock, in the woods, with a rotary dial phone and sloooowwww internet connection), so all I've got access to is my Powerbook. I've asked a friend to log on with their PC and send me the FTP transcript. I'll post it as soon as I've got it.

    We're having trouble with a CGI script, and I can't access it to fix it - it's driving me crazy. I've been using Fetch since about 1995 and this is the first time I've had this problem.

    Thanks for your help.

    It looks to me as if a NAT device on the server side is keeping PASV mode from working. Do you have a firewall (such as the OS X firewall) enabled on your PowerBook? That would keep non-PASV mode from working.

    Thanks,

    That's it! It was my own personal firewall. I'm running Norton Personal Firewall on OS 8.6, and when I turned that off, as well as turning off the PASV, I finally got the file list.

    Thanks, Jim. You're the best!!!!!
