Python Scanner

Hi, I would like to know how can I detect what server is using some web site?, what OS?, version? and all that kind of info. Im trying something like:

Code:

import asyncore, socket

class AsyncGet(asyncore.dispatcher):
    def __init__(self, host):
        asyncore.dispatcher.__init__(self)
        self.host = host
        
        self.create_socket(socket.AF_INET, socket.SOCK_STREAM)
        self.connect((host,80))
                     
        self.request = 'GET /index.html HTTP/1.0\r\n\r\n'
        self.outf = None
        print 'Requesting server from',host

Is that correct?

Way, pretty low level thing you got going on there.. you can get quite allot of info about a webpage very easily with the urllib module..

>>> import urllib
>>> urllib.urlopen('http://www.python.org/').info()
<httplib.HTTPMessage instance at 0x01074558>
>>> print urllib.urlopen('http://www.python.org/').info()

>>> print urllib.urlopen('http://www.python.org/').info()['Server']
Apache/1.3.26 (Unix)
>>> >>> d = dict(urllib.urlopen('http://www.python.org/').info())
>>> d
{'content-length': '10611', 'via': '1.1 webcacheB10 (NetCache NetApp/5.3.1D2)', 'age': '255', 'server': 'Apache/1.3.26 (Unix)', 'last-modified': 'Sat, 22 Nov 2003 18:48:15 GMT', 'etag': '"5a7599-2973-3fbfaf6f"', 'date': 'Fri, 28 Nov 2003 23:25:38 GMT', 'content-type': 'text/html', 'accept-ranges': 'bytes'}
>>>

You have Server type, version and platform all in one key! What other info are you trying to get here?

Mark.

as far as i know your can't.. or not with a spacific module, if you had SSH/telnet access you should connect to the server and check what ports are open from there using the telnetlib module..

My best bet would be to try and connect to each port one by one (i dont know how fast this will be) and return only the open ports..

If i think of another way i'll let you know!
