Im trying to connect to an ftp server that is behind ftp proxy. The proxy server does not require username and password, the ftp server does. I have searched through several posts:
How to use urllib2 to access ftp/http server using proxy with authentification
How to connect to ftp server via proxy using ftplib
How to specify an authenticated proxy for a python http connection?
Here is the last version of my code. So far I've figured out that to open the ftp server behind an ftp proxy, the notation ftp://username:password@server can be used. I'm using the urllib2 library to define the proxy server.
import urllib2
proxy_host = '101.11.44.84:8021' # only host name, no scheme (http/ftp)
proxy_handler = urllib2.ProxyHandler({'ftp': proxy_host})
auth = urllib2.FTPHandler()
try:
opener_thru_proxy = urllib2.build_opener(proxy_handler, auth)
except:
logger.exception('build_opener error')
raise
print opener_thru_proxy
try:
conn = opener_thru_proxy.open('ftp://user:password@100.159.66.113')
except:
logger.exception('opener thru proxy error')
raise
print conn.read()
conn.close()
The output of this code yields:
2016-05-23 16:15:28,286 - root - ERROR - opener thru proxy error

It seems that I'm unable to establish the ftp connection with the ftp server. However, when I use the same set of connection data and use it in Total Commander, the connection works correctly. See the image enclosed Total Commander ftp connection window.
