What is PASV? (4 posts)

Unless I check PASV in the Firewall Preferences, I cannot use Fetch 3.0.3. What exactly is PASV and does it compromise my Firewall at all? Thanks.

You can read about the difference between active and passive (PASV) mode FTP here.
PASV does not compromise your firewall. Your firewall blocks connections coming into your network from the Internet; in passive mode all your connections go out from your computer to the Internet.

I recently had a vendor request that the PASV be turned off while uploading files to their ftp site. If I can only upload files with PASV turned on, will that mess up the transfer?

If you can successfully connect to their server and upload files to their server with PASV, then it shouldn't mess up anything.
The usual reason for making that request is that PASV doesn't work with their server - if PASV does work, you should ask them why they don't want you to use it when uploading to their site (and pass along the answer here, we'd be curious to hear it).
