sftp using ftplib

问题:

I need to download a file from a host using sFTP.

Do you know if is it possible to do that using python ftplib? I saw an example here, but when I try to connect I receive EOFError.

I tried this code:

import ftplib
ftp = ftplib.FTP()
ftp.connect( "1.2.3.4", "22" )

This method returns with an error after long time so I cannot perform a call to login. I cannot try the constructor FTP([host[, user[, passwd[, acct[, timeout]]]]]) because my port is 22 but ftplib default is 21.

If I follow the example

ftp = ftplib.FTP("1.2.3.4")
ftp = ftplib.FTP("1.2.3.4","22")

I receive a connection refused so I cannot enter any username password. Can you help me? Thank you very much

As the question you linked to states, ftplib doesn't support sftp (which is FTP over SSH and has nothing to do with FTPS, FTP over SSL). Use the recommended paramiko instead.
