LinuxQuestions.org - can anyone help me pl with this eror i a python script

i made this script about 3 months ago and it was working very good till few days ag where i started getting this error and i don't know why

Code:



import urllib, commands, datetime

i = commands.getoutput("lynx -dump -nolist -auth safrout:sa1782ao http://10.0.0.138/ip.htm | grep '^ *[0-9].*ppp$' -m 1 | cut -c 4-15")

x= commands.getoutput ("host safrout.homelinux.net | cut -c 35-46")

url="http://aokda:saf1782ao@members.dyndns.org/nic/update?system=dyndns&hostname=safrout.homelinux.net&myip="+i+"&wildcard=OFF&backmx=NO&offline=NO"

def compare():

  if x == i :

    print datetime.datetime.now(),"-->", i,"=", x

    exit

  else:

    url_new = urllib.urlopen(url)

    print datetime.datetime.now(), "ur IP was changed to ", url_new.read(), ", and it up2date now :)"

compare()

and the error looks like this

Code:

safrout@home IP-Update $ python ip_update.py

Traceback (most recent call last):

  File "ip_update.py", line 12, in ?

    compare()

  File "ip_update.py", line 10, in compare

    url_new = urllib.urlopen(url)

  File "/usr/lib/python2.3/urllib.py", line 76, in urlopen

    return opener.open(url)

  File "/usr/lib/python2.3/urllib.py", line 181, in open

    return getattr(self, name)(url)

  File "/usr/lib/python2.3/urllib.py", line 281, in open_http

    if not host: raise IOError, ('http error', 'no host given')

IOError: [Errno http error] no host given

maybe it is a silly error but really i can't figure it out
