Hi all,
I have a problem trying to FTP from a Mac to a Mac through my ABS but can do so from a PC (windows machine).
I have a webserver http://jeanmatthieu.free.fr/pureftpd/ installed on one of my Macs which is connected to the internet via my ABS (snow). My other Mac is connected to the net via a dial-up modem. I can successfully FTP to the Mac with a webserver using an FTP application on a PC, but I am unable to successfully connect from a Mac using an FTP appllication (I have tried Transmit, Fetch, and Cyberduck). The Mac FTP application connects but will not list the files on the FTP server, eventually timing out (see Transmit log below). I can successfully FTP Mac to Mac if the server is connected to the net through ethernet and not my ABS.
Can anybody give me pointers as to what I need to do to solve this.
Thanks

Sounds like a configuration issue. Is the Mac using Passive FTP? What about the PC?

Hi,
I have tried both PASV and Active. The Mac and PC FTP clients are both using Active FTP. PASV won't allow the FTP client to connect. I had to set a PASV rule in Sharing to allow FTP connections.
Any other pointers please?

Is the firewall active on the Mac (or is it behind a router)? Using Active FTP requires the ability to open up arbitrary ports on the client computer which a firewall would prevent.

Hi, thanks for your reply.
My internet connection is from a DSL cable modem, this then connected to my Airport Base Station, which in turn connects wirelessly to my Mac.
What I find strange is that a PC using CoreFTP client can connect but Mac FTP clients (Transmit, Fetch, Cyberduck) cannot.
Which arbritrary ports do I need to open?
Thanks
