ftp - Python ftplib connection error (gaierror)

Question

I am trying to make a very basic FTP client in python, and within the first few lines of code I have already run into a problem

My Code:

from ftplib import FTP
ftp = FTP('ftp.mysite.com')

With this code, and with countless different urls used, I will always get the same error:

gaierror: [Errno 11004] getaddrinfo failed

Answer 1

I found myself here with this error trying to connect using the full path rather than just the hostname. Make sure you split that out and use cwd(path) after login().

For example:

ftp = FTP('ftp.ncdc.noaa.gov')
ftp.login()
ftp.cwd('pub/data/noaa/2013')

instead of:

# Doesn't work!!
ftp = FTP('ftp.ncdc.noaa.gov/pub/data/noaa')
ftp.login()
ftp.cwd('2013')

Kind of obvious in hindsight, but hopefully I help you notice your simple mistake!
