Hace un par de semanas, DynDNS cambió su política de uso de las cuentas gratuitas para incluir una cláusula por la cual es necesario hacer mínimo un login al mes si no se quieren perder los dominios que tengamos:
Starting now, if you would like to maintain your free Dyn account, you must log into your account once a month. Failure to do so will result in expiration and loss of your hostname. This activity helps us eliminate hostnames that are no longer needed and/or dormant. Note that an update client will not suffice for this monthly login.
El siguiente script permite iniciar sesión haciendo uso de la librería
mechanize para Python:
#!/usr/bin/env python
import mechanize
import cookielib
LOGIN_URL = "https://account.dyn.com/entrance/"
USERNAME = "username"
PASSWORD = "password"
# Browser
br = mechanize.Browser()
# Cookie Jar
cj = cookielib.LWPCookieJar()
br.set_cookiejar(cj)
# Browser options
br.set_handle_equiv(True)
br.set_handle_redirect(True)
br.set_handle_referer(True)
br.set_handle_robots(False)
# Follows refresh 0 but not hangs on refresh > 0
br.set_handle_refresh(mechanize._http.HTTPRefreshProcessor(), max_time=1)
# User-Agent (this is cheating, ok?)
br.addheaders = [('User-agent', 'Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.1) Gecko/2008071615 Fedora/3.0.1-1.fc9 Firefox/3.0.1')]
# Open some site, let's pick a random one, the first that pops in mind:
r = br.open(LOGIN_URL)
html = r.read()
# Select the second (index one) form
br.select_form(nr=1)
br.form["username"] = USERNAME
br.form["password"] = PASSWORD
br.submit()
if br.response().read().find(USERNAME) >= 0:
print("OK")
else:
print("KO")
