Log into FTP With proxy

Is it po开发者_如何学Gossible to write Perl (or other language) code that logs into an FTP server with proxy?

Yes. See here http://perldoc.perl.org/Net/FTP.html

Firewall - The name of a machine which acts as an FTP firewall. This can be overridden by an environment variable FTP_FIREWALL . If specified, and the given host cannot be directly connected to, then the connection is made to the firewall machine and the string @hostname is appended to the login identifier. This kind of setup is also referred to as an ftp proxy.

But it's a question so obviously answerable by googling (it was the first match for "perl ftp proxy") that there must be more to the question. Tell us more about what you're trying to do.
