Getting the connected user's ip in python

Expand Post »

Hi there,

Trying to write a small script in python. What it will basically do is this;

1- A SSH user initiates the python script (from SSH remotely)
2- The script gets the connected users IP (the user is connected through SSH)
3- The connected IP is sent back to the user

I got the part where the user initiates script (the easiest part so far)
I also got to write to a file and send the same file using SSH and Python

The part I need help is in the step 2

I am a first time Python programmer. Been using it for three days so be kind to me please ^_^

Re: Getting the connected user's ip in python

to get your computers ip, try

python Syntax (Toggle Plain Text)
>>> import socket
>>> socket.gethostbyname(socket.gethostname())
>>> import socket
>>> socket.gethostbyname(socket.gethostname())

Doesn't this give the python-running machine's IP ?

Or does it give the IP of the machine that calls it?

It just gave me 127.0.0.2 ?? which isn't really the ip i tried to run the python from

I know that 127.0.0.1 is localhost but what is 127.0.0.2 ?

Re: Getting the connected user's ip in python

Found a better way to solve my find external IP problem with Python. It was foolish of me trying to find it through SSH while there were so many other tools out there.

Python Syntax (Toggle Plain Text)
    def getIPAddress(self):
        """
           This function gets your external ip
           from whatismyop.com
           this program must be called every
           5 minutes not more or else you must
           have your own server.
        """
        site = urllib.urlopen("http://www.whatismyip.com/automation/n09230945.asp").read()
        grab = re.findall('\d{2,3}.\d{2,3}.\d{2,3}.\d{2,3}',site)
        address = grab[0]
        return address
    def getIPAddress(self):
        """
           This function gets your external ip
           from whatismyop.com
           this program must be called every
           5 minutes not more or else you must
           have your own server.
        """
        site = urllib.urlopen("http://www.whatismyip.com/automation/n09230945.asp").read()
        grab = re.findall('\d{2,3}.\d{2,3}.\d{2,3}.\d{2,3}',site)
        address = grab[0]
        return address

In the end the above code was used. Thanks for all your help anyway.
