Ping() issue

[mLipok]

I have problem with:

_Example()
Func _Example()
    Ping('google.com', 20)
EndFunc

Never ends......

so I checked ping in CMD console, the same problem, even If I ping my local router.

But internet works fine.
I already restart WifiConnection
Also I switch to another router (Tehering for my smartphone)

 

Question 1:
Anybody know what is fix for this issue (I will restart Windows as soon as I post this topic)
EDIT 1: after restart - issue still exist

Question 2:
Why Ping.exe and Ping() from AutoIt never ends ?

 

EDIT 2: I have ESET SmartSecurity - but turn off Firewall, and still not fixed

If you can browse the web, that means DNS, HTTP and HTTPS traffic is working. I suspect it is some firewall blocking ICMP; could be the router (0.1), or perhaps firewall software on your computer.

Can you ping any other local computers, including your own IP?  Is this a personal computer, company computer?

Found this....

So this is really freak AV (ESET Security) issue.

Translation by hand:

Quote

connection refuesed by the rule "Block connection on ICMP protocol"

When I click unblock ..... then I saw "Please wait" and nothing happend for few minutes

 

I also notice that I can not change anything in my ESET configuration.
I finally call to ESET Helpdesk...

For now the proposed solution is to reinstall ESET .....

But the question is:

Why Ping() stoped AutoIt execution (even if I set TimeOut parameter) ?

I too use Eset (simple NOD32, not the Endpoint product) and have zero issue pinging the world.

Note that your ISP may block ICMP requests.

Good question Dorothy. It should not happen.
But living in a moment of high strangeness, posting Windows version and build, and AutoIt version can come in handy. Also trying versions 3.3.8.1 and 3.2.14.x can show if it ever had a problem.
All this may help, but unless the problem can get replicated, it can not be observed by others to bring about a solution.

...then that shows, that is not necessarily AutoIt but likely, the anti-virus solution

(I am assuming you're running Windows 10, by the look of the command line at top)

Have you tried to repair the TCP/IP stack?

Type netsh winsock reset and press Enter.
Type netsh int ip reset and press Enter.
Type ipconfig /release and press Enter.
Type ipconfig /renew and press Enter.
Type ipconfig /flushdns and press Enter.

Also if using Windows 10, there are auto-adjustments. Let me stress "AUTO". So windows is supposed to fix this automatically.
Sometimes it fails.

Here's an interesting link and it might help, assuming this is TCP/IP related.
https://docs.microsoft.com/fr-fr/archive/blogs/netgeeks/a-word-about-autotuninglevel-tcp-receive-auto-tuning-level-explained

Finally I'm lazy. I use TCP Optimizer. It will create a backup file before it does any changes. It can fix your stack in a jiffy. Make sure you run it as administrator. If you're paranoid, go into system restore and create a restore point.
So now you've got some options.

This being said, I've never seen Ping not completing. 

If all else fails scan your computer for spyware (assuming ESET isn't intercepting it) . Here's my favorite quick-fix tool : https://fr.malwarebytes.com/adwcleaner/ Apparently malware can graft itself within the stack (which is why we reset it).
In any case, ADWCleaner saved my client's bacon many times. Worth it's weight in gold.

Typical tech support response

And it indeed looks like the Ping function in AutoIt has a bug, it should return if a timeout is defined.

Few hours before I had a problem with Internet on my router so I switch to SmartPhone Tehering.
Then I switch back to router (TPLink + DDWRT).

The problem was in ESET AV which block each ICMP connection (PING) this mean all Incoming/Outgoing PING connection was dropped by my ESET AV FIREWALL software.
But.. this was not only one prolbem with this AV software.
ESET had an issue as I could not even change configuration.

After ESET resintall all was fine.

And this is the main problem which I'm asking for.
But you must take into account, that this is not only issue wiht AutoIt Ping() function .
The same problem have ping.exe from MS Windows instalation.

So it seams that AutoIt use the same Windows API as ping.exe  .... which mean that probably this is internal windows issue.

 

btw.

You can easly simulate this issue by blocking all connection for ICMP on your computer.

EIDT:
I use ESET software for long time (more than 10 years), on more than 200 PC's,  and this is the first time when I had such problem.

Really? I dropped eset ys ago due to all it’s windows issues. It’s garbage. Use windows built-in defender and that’s all you need maybe Malwarebytes in addition

I see, that is interesting.

I do the same, it works good enough when you follow safe practices. Not sure about MalwareBytes, I never used it.
