    First thing you should do is to remove the -o => 'PreferredAuthentications publickey' part that is not really required and may interfere with Net::SFTP::Internals... unless you have some reason to include it!

    Do you know the vendor and version of the remote software? you can just telnet the server at port 22 and it will tell you.

      I have tried without -o => 'PreferredAuthentications publickey' this too. It was not working. I did telnet. -> telnet 121.241.2.65 22 Its showing this Telnet: connect to address 121.241.2.65: Connection timed out although when i used the port provided by the vendor I got this output Trying 121.241.2.65... Connected to 121.241.2.65. Escape character is '^]'. SSH-2.0-OpenSSH_5.3 Connection closed by foreign host.
