Re: [Net::FTPServer] FTP<>SFTP bridge?

[Yair Lenga]

Hi,

I'm using Net::FTPServer in production - and I have the same request 
from my clients - add support for SFTP. Does any one have any pointers 
on how to start solving  this problem ?  I'm quite familiar with the FTP 
protocol, and the Net::FTPServer - and almost clueless as the the SFTP 
protocol.

Is it simply wrapping of the FTP control (and possibly data) ports 
inside SSL, or does it include full tunnelling of both the data and the 
client thru SSH tunnel ?

Thanks
Yair
