AsyncPing

AsyncPing is an async-friendly pure python3 version of ICMP ping implementation using raw sockets.
(Note that on Linux and Windows, ICMP messages can only be sent from processes running as root.)

The Python2 version originally from here.
The Python3 version originally from here.
This version maintained at this github repo.

Get Started

• If you met "permission denied", you may need to run this as root. Alternatively see this for troubleshooting on linux.

pip install asyncping3

>>> from asyncping3 import ping, verbose_ping
>>> anyio.run(ping,'example.com')  # Returns delay in seconds.
0.215697261510079666

>>> anyio.run(verbose_ping,'example.com')  # Ping 4 times in a row.
ping 'example.com' ... 215ms
ping 'example.com' ... 216ms
ping 'example.com' ... 219ms
ping 'example.com' ... 217ms

$ pping example.com  # Verbose ping.
ping 'example.com' ... 215ms
ping 'example.com' ... 216ms

Installation

pip install asyncping3  # install asyncping3
pip install --upgrade asyncping3  # upgrade asyncping3
pip uninstall asyncping3  # uninstall asyncping3

Functions

>>> from ping3 import ping, verbose_ping

>>> ping('example.com')  # Returns delay in seconds.
0.215697261510079666  # `0.0` returned means the delay is lower than the precision of `time.time()`.

>>> ping('not.exist.com')  # If host unknown (cannot resolve), returns False.
False

>>> ping("224.0.0.0")  # If timed out (no reply), returns None.
None
