    I'm using Fetch 4.0.3 on Mac OS X 10.3.2. Everything was working fine until recently, when I found that I could access certain FTP sites, but not others, even though I had permission to access them (even some I administer as webmaster). I have checked my settings, and tried different schemes, but none have seemed to work. Do you have any suggestions?

    Right now, I have tried to log into one of these sites, and all that is happening is that the dog is running, and the dialog says that it is "getting file list..."

    Thanks in advance for your help...

    The first thing I'd try is toggling the setting of the "Use passive mode transfers (PASV)" box in the Firewall section of Fetch Preferences. If that does not help could you choose "Fetch Transcript" from the Window menu and post the contents after you see the problem?

    Thanks,

    That was the first thing I tried, but no luck. Here is a transcript from one of the FTP sites (which I know is working) that I tried to log into, but couldn't.

    Thanks in advance for your help!

    Do you have the OS X firewall enabled (or a firewall device on your network)?

    Can you connect to ftp.fetchsoftworks.com (leave the User ID and Password fields blank) and get a file list there? How about with "Use passive mode transfers (PASV)" checked?

    Thanks,

    I tried with PASV mode on and off

    Off - couldn't get directory

    On - did

    However on isn't sloving the problem with my other servers. 4.0.3 with Panther.

    As I mentioned in another post - no matte the settings or version, this isn't working for us with Panther, though just fine with Jaguar

    here's the transcript from connecting to fetchsoftworks

    Played around a bit more...

    With Panther & Fetch 4.0.3, turning off the firewall and NOT checking passive mode works fine...

    HOWEVER, we really need to have the firewall active on our machines (laptops) With the firewall active, no matter whether passiv eis on or off, it simply will nt connect.

    Any advice or thoughts?

    You are probably stuck unless you get the server administrator to support passive mode. Non-passive mode does not work with a firewall software running on your Mac.

    Thanks-
    I was thinking that the OS may be at fault. But if I turn off the firewall (or Norton), what type of security risk am I running? Would it be better to run the FTP off another Mac running Jaguar, if this is available? At least until a fix comes?

    After playing around a bit more, we find a solution that allowed us to leave the firewall on - its just weird though.

    We started the personal ftp server on laptop we were originally having problems with and ftp to the original external server was suddenly possible.

    Of course now the laptop is technically open to ftp access, but that can be addressed. Trading one vulnerability for another. Though I suppose restrcting ftp access to only user accounts on the system is far better than not using the firewall at all.

    Not even sure why this had any effect - let alone a positive one.

    I really can't see how running a laptop without a firewall active is a real option.

    Is there a fix planned for this on Fetch's side of the gameboard or is this something in Apple's court?

    (not trying to put you in an awkward spot, Jim - actually not even sure you would know this - I'm just trying to figure out where I should be looking for other possible answers)

    The issue is inherent in the FTP protocol. To do an FTP file transfer (or even list the contents of a directory) there has to be a second connection, called the data connection, and that connection is made to a different port number each time.

    If you use PASV mode the data connection is made from your Mac to the server. That works most of the time, but it sounds like this particular server blocks incoming PASV connections. The other option is to uncheck the PASV option and have the server connect back to your Mac. But for that to work you can't have a firewall running on your Mac. You can't work around the problem by opening a few ports in the firewall because the port number changes each time you transfer a file or list a directory.

    I would petition the server administrator to allow passive mode transfers; it's the recommended method, and would let you keep running a firewall.
