I might be getting closer. Now I am getting "I/O error(ftp error):
(111, 'Connection refused')" error with the following code:
import urllib2
proxies = {'ftp':'ftp://proxy_server:21'}
ftp_server = 'ftp.somecompany.com'
ftp_port='21'
username = 'aaaa'
password = 'secretPW'
password_mgr = urllib2.HTTPPasswordMgrWithDefaultRealm()
top_level_url = ftp_server
password_mgr.add_password(None, top_level_url, username, password)
proxy_support = urllib2.ProxyHandler(proxies)
handler = urllib2.HTTPBasicAuthHandler(password_mgr)
opener = urllib2.build_opener(proxy_support)
opener = urllib2.build_opener(handler)
a_url = 'ftp://' + ftp_server + ':' + ftp_port + '/'
print a_url
try:
data = opener.open(a_url)
print data
except IOError, (errno, strerror):
print "I/O error(%s): %s" % (errno, strerror)
