How can I ping a specific port and report the results?

Question

I'm making a discord bot for my friends. This one feature, !status, is supposed to ping the server and report the replies.

    from tcping import Ping
    if message.content.startswith('!status'):
        ping = Ping('HOST', 25565)
        response = ping.ping(1)
        await message.channel.send(str(response))

The problem is, the bot only responds with "None." Any help?

Im guessing you want to see if there is something available (as opposed to ping) ... if thats true this might work for you ...

import socket

def check(host,port,timeout=2):
    sock = socket.socket(socket.AF_INET,socket.SOCK_STREAM) #presumably 
    sock.settimeout(timeout)
    try:
       sock.connect((host,port))
    except:
       return False
    else:
       sock.close()
       return True

print(check('google.com',1234,timeout=1))
print(check('google.com',443,timeout=1))

maybe you want to time this... easy enough

import time
def timed_check(host,port,timeout=2):
    t0 = time.time()
    if check(host,port,timeout):
       return time.time()-t0 # a bit inexact but close enough

print(timed_check('google.com',1234,timeout=1))
print(timed_check('google.com',443,timeout=1))

or maybe you want stats

def timed_stats_check(host,port,timeout=2,retries=5): 
    minimum,maximum,sumation = float('inf'),float('-inf'),0
    errors = 0
    for i in range(retries):
        t = timed_check(host,port,timeout)
        if t is None:
           print("ERROR Unreachable...")
           errors += 1
        else:
            print(f"Time {t:0.5f}s")
            maximum = max(maximum,t)
            minimum = min(minimum,t)
            sumation += t
    if retries > 0:
        print(f"Max Time: {maximum:0.5f}s")
        print(f"Min Time: {minimum:0.5f}s")
        print(f"Average: {sumation/(retries-errors):0.2f}s")
    print(f"Failures: {errors}/{retries}")
