ping program in Python - Skaperen - Mar-02-2022

i am looking for a Python3 implementation of the ping program. i've already done one that invokes /bin/ping and it is too awkward to do what i want (timing changes for the ping packets).

RE: ping program in Python - BashBedlam - Mar-03-2022

Here is a simplified example using therequestslibrary.
import requests
from time import time

while True :
	start_time = time ()
	print (requests.get ('https://youtube.com'), end = ' ')
	print (f'{time () - start_time:.3f}')

Did you search PyPI?

RE: ping program in Python - Skaperen - Mar-03-2022

i don't understand how that requests example sends and receives a ping packet.

i searched PyPi but nothing looked promising. it's hard to search there

RE: ping program in Python - ndc85430 - Mar-03-2022

Yeah, Requests does HTTP not ICMP.

What did you find on PyPI and what was hard about searching? You might also try searching GitHub.

A standard search eg google you should be able to find something.
These took me not long time to find,can also test all.
icmplib | pythonping | ping3.
icmplib(GitHub) maybe the best one a modern implementation of the ICMP protocol in Python.
from icmplib import ping, multiping, traceroute, resolve

print(ping('google.com', count=4))
Output:
  142.250.74.142
------------------------------------------------------------
  Packets sent:     4
  Packets received: 4
  Packet loss:      0.0%
  Round-trip times: 44.0 ms / 46.749 ms / 51.999 ms
  Jitter:           2.666 ms
------------------------------------------------------------
The rest.
import subprocess
from pythonping import ping
from ping3 import verbose_ping

# The one on OS
output = subprocess.run(['ping', 'google.com'], capture_output=True, encoding='utf-8')
print(output.stdout)

print('-' * 50)
# pip install pythonping
ping('google.com', verbose=True)

print('-' * 50)
# pip install ping3
verbose_ping('google.com')
Output:

does that mean to concatenate the two source blocks? i assume yes ...

there are 2 imports bringing in the name "ping" at line 1-1 and line 2-2. so, which should i use?

The last code is just 3 different solution's run at once,just spilt it up want to use one them.

After looking at this the clear best implantation is icmplib,and what i would advice to use.
from icmplib import ping
 
print(ping('google.com', count=4))

RE: ping program in Python - Skaperen - Mar-04-2022

i want my code to run while the ping is on its way there and the reply is on its way back. i need to send a ping request every second, wake up in X seconds and check if anything was received. if not, run the fixer script (i'm thinking it should wait for it).

edit 1:

so, i need a means to send pings separate, then i need a means to get what comes back when it does, separate from other traffic from the same host (i may be pinging it manually in some virtual terminal.

Cool, you can use it as unprivileged user.

import os
import time
import icmplib


def pinger(host, callback=None, timeout=1, *cb_args, **cb_kwags):
    def ping():
        privileged = os.getuid() == 0
        return icmplib.ping(
            host, count=1, timeout=timeout, privileged=privileged
        ).is_alive

    while True:
        time.sleep(1)
        if not ping():
            print(host, "is dead")
            if callable(callback):
                callback(*cb_args, **cb_kwargs)
        else:
            print(host, "is alive")


pinger("google.de")
