Hi everyone,

I have question about SFTP's connection modes. FTP can use Active or Passive
mode for same.

Is SFTP also supports such modes?

Thanks.

It does not need the distinction. SFTP connects via ssh on port 22
only.

Active vs passive has to do whether both the server and the client
make connections (active aka original) or only the client makes
connections (passive). In the SFTP protocol only the client initiates
connections, so you can think of SFTP as always being in passive mode.

You might want to read more about how active and passive modes work
here: http://slacksite.com/other/ftp.html.

This question and the others you have asked lead me to believe you
want an FTP client, but want the connection to be secure. SFTP is not
your only choice. You can also use FTPS:
http://en.wikipedia.org/wiki/FTPS. FTPS is FTP tunneled over SSL.
There is even a Perl module for it
http://search.cpan.org/dist/Net-FTPSSL/FTPSSL.pm.

server.
