I'm trying to help a user who can't FTP from OS X 10.2; the server
never receives the passive mode data connection. The strange thing
is that the built-in ftp client works, as does Fetch 3.0.3 running in
Classic. But FTP clients that run native and use Open Transport APIs
-- Fetch 4.0.2, Captain FTP, and NetFinder -- all fail to connect.
As far as I can tell the only distinction between the programs that
work and the ones that don't is the API they use. I've seen one
other case like this -- running the NortonPrivacyControl feature of
Norton Personal Firewall on OS X blocks uploads of some text files
with Fetch, but not with the command-line FTP client. I assume
that's because the Norton software catches calls to the OT API but
not BSD socket calls, but I don't know exactly why.
So are there "patching" mechanisms that would draw a distinction
between networking APIs? Does the built-in firewall software?
Thanks,
