I have created a network scanner, that looks for a specific port on a range of IP's. I would like to thread the application but I am getting and error message

ERROR: for worker in range(network.hosts): TypeError: 'method' object cannot be interpreted as an integer

Now I understand why the error is there it is because the IP Address is not an INT. However, what I would prefer to do is split the subnet into equal parts and run X number of IP's on a per thread bases.


Thread 1 192.168.1 - 30 Thread 2 192.168.31 - 60 Thread 3 192.168.61 - 90 Thread 4 192.168.91 - 120 Thread 5 192.168.121 - 150 Thread 6 192.168.151 - 180 Thread 7 192.168.181 - 210 Thread 8 192.168.211 - 240 Thread 9 192.168.241 - 254

Something along these lines. I"m not quite sure how to do this. I am posting the main function, the tcp ping and the threading function.

I suspect I need to get a list of IP's and then somehow tell the thread to execute on X number of IP's at a time but not really sure how to do that.

Thanks for the help in advance

First off I let this question season since I'm not a python guru. But as I code in many languages the error looks to be that something expects an integer and that's it.

Read https://stackoverflow.com/questions/28036309/typeerror-list-object-cannot-be-interpreted-as-an-integer to see if this kicks the problem loose for you.

I can't tell which line is in error so I can't do much else but agree that the error message is telling us what is wrong.

What does worker in range(network.hosts) require? Some IP address? That may not be an integer but something like or IP notation.

Here's an idea, you can ping by integer. Here's how. http://www.aboutmyip.com/AboutMyXApp/IP2Integer.jsp
