Nice.
Can you update this so it works if you have DSL or Cable modem, or if you are behind a router ? Gethostbyname() will only return the INTERNAL address of your machine, which is not addressable from the outside world, UNLESS you know your cable/DSL modem address.
Give this a try ;). This will give you the ip or the gateway, which is what you need. Just replace ip=socket.gethostbyname(blah) with this code.
import os,string
address={}
cmd = 'c:/windows/system32/ipconfig.exe /all' # whatever your path
junk, txtOut = os.popen2(cmd)
for x in txtOut.readlines():
print address['gate']
ip=address['gate'] #replace the old ip way with this.
print address['ip']
Detect current ip using http://checkip.dyndns.org. I added this function to read the ip address from http://checkip.dyndns.org
def readip(): import re, urllib f = urllib.urlopen('http://checkip.dyndns.org') s = f.read() m = re.search('([\d].[\d].[\d].[\d])', s) return m.group(0)
and changed the calls to socket.gethostbyname(name) by calls to the new function. The start() function ended up like this:
def start(): def getIP(name, path): ip = readip() print 'Current ip: '+str(ip) open(path,'w').write(ip) #Save the current IP address. out(name,Path_dat)
Thanks for posting this useful program! Later I will work on updating the entry in www.dyndns.org, to have the complete package: detection of the IP change and update of the dns record in www.dyndns.org.
Detect current ip using http://checkip.dyndns.org - fixed format. My previous post did not display well, this is the fixed and shortened version.
I added this function to read the ip address from http://checkip.dyndns.org
There are other places that provide the same service (free); the function should work with many of them with minor o none modifications: it will parse the first occurrance of an ip-address like string and return it.
def readip():
import re, urllib
f = urllib.urlopen('http://checkip.dyndns.org')
s = f.read()
m = re.search('([\d].[\d].[\d].[\d])', s)
return m.group(0)
I changed the calls to socket.gethostbyname(name) by calls to the new function readip()

How can i check the change of ip adrress of a remote machine. I have some 10 machines in my network, and two machines ip adresses are overlapping with each other, so i want to know which are the two machines among those 10 machines that have the same ip adresses. Yogi
Re: Detect current ip using http://checkip.dyndns.org. This piece of code is simpler and cleaner:
