pythonping

PythonPing is simple way to ping in Python. With it, you can send ICMP Probes to remote devices like you would do from the terminal. PythonPing is modular, so that you can run it in a script as a standalone function, or integrate its components in a fully-fledged application.

Basic Usage

The simplest usage of PythonPing is in a script. You can use the ping function to ping a target. If you want to see the output immediately, emulating what happens on the terminal, use the verbose flag as below.

from pythonping import ping


ping('127.0.0.1', verbose=True)

This will yeld the following result.

Reply from 127.0.0.1, 9 bytes in 0.17ms
Reply from 127.0.0.1, 9 bytes in 0.14ms
Reply from 127.0.0.1, 9 bytes in 0.12ms

Regardless of the verbose mode, the ping function will always return a ResponseList object. This is a special iterable object, containing a list of Response items. In each response, you can find the packet received and some meta information, like the time it took to receive the response and any error message. You can also tune your ping by using some of its additional parameters:

• size is an integer that allows you to specify the size of the ICMP payload you desire
• timeout is the number of seconds you wish to wait for a response, before assuming the target is unreachable
• payload allows you to use a specific payload (bytes)
• count specify allows you to define how many ICMP packets to send
• sweep_start and sweep_end allows you to perform a ping sweep, starting from payload size defined in sweep_start and growing up to size defined in sweep_end. Here, we repeat the payload you provided to match the desired size, or we generate a random one if no payload was provided. Note that if you defined size, these two fields will be ignored
• df is a flag that, if set to True, will enable the Don't Fragment flag in the IP header
• verbose enables the verbose mode, printing output to a stream (see out)
• out is the target stream of verbose mode. If you enable the verbose mode and do not provide out, verbose output will be send to the sys.stdout stream. You may want to use a file here, for example.

Advanced Usage

If you wish to extend PythonPing, or integrate it in your application, we recommend to use the classes that are part of Python Ping instead of the ping function. executor.Communicator handles the communication with the target device, it takes care of sending ICMP requests and processing responses. It ultimately produces the executor.ResponseList object. The Communicator needs to know a target and which payloads to send to the remote device. For that, we have several classes in the payload_provider module. You may want to create your own provider by extending payload_provider.PayloadProvider. If you are interested in that, you should check the documentation of both executor and payload_provider module.
