Ping Function always return 4.

[GraaF]

I've been playing around with the ping function, and according to the help page, the ping function should be able to return 4 types of errors.

But no matter what i do, no matter what i enter into the ping field, it returns error 4 for some reason? I tried with countless stuff, am i misusing the function?

Success:	the roundtrip-time in milliseconds ( greater than 0 ).
Failure:	0 if host is not pingable or other network errors occurred and sets the @error flag to non-zero.
@error:	1 = Host is offline 2 = Host is unreachable 3 = Bad destination 4 = Other errors

GUICtrlSetData($probar, "Testing connection..")
            $inettest1 = ping("www.Imnotawebsite.nope", 250)
            If $inettest1 Then
            GUICtrlSetData($probar, "Connection was made after: " & $inettest1 & "MS")
         Else
            If @error = 1 Then
            GUICtrlSetData($probar, "An unknown error occurred code: " & @error)
         Else
            If @error = 2 Then
            GUICtrlSetData($probar, "An unknown error occurred code: " & @error)
         Else
            If @error = 3 Then
            GUICtrlSetData($probar, "An unknown error occurred code: " & @error)
         Else
            If @error = 4 Then
            GUICtrlSetData($probar, "An unknown error occurred code: " & @error)
         EndIf
         EndIf
         EndIf
         EndIf
         EndIf

I mean i can ping google.com and the script run fine, but incase i ping a domain thats offline it will return the error 4 instead of error 1?..

The function works fine, but i don't like that no matter what goes wrong in the function it will return the error code 4, while error code 1 might have been the problem.

 

Let me explain:

If i ping www.google.com no problem, no errors everything is perfect.

Now lets say i ping a domain which is offline the script SHOULD return error code 1 or 2, yet i get error code 4.

Have you tried it on a real domain that is off-line rather than a made up domain that does not exist. I correctly get @error = 2 for domains at work that I know exist but are unreachable from my home PC.

Yeah i tried with websites that are unreachable from here, still error 4.

[JohnOne]

Have you tried changing An unknown error occurred code to the real corresponding error?

What about supplying some exact information so we can actually check it?

It prompt

"An unknown error occurred" & @error

@Error part shows the real error..

What information would you like? I included the script & as i said before i tried with multiply real and fake websites it either run right through no errors or return error 4.

 

[Jos]

Show us a script that can be ran with the hostnames you are testing with would help for starters.

GraaF,

This works for me...

#include <array.au3>

Local $aURLS = [ _
        'www.google.com', _
        'www.autoitscript.com', _
        'www.probablynotawebsite.com', _
        'www.samolyk.net' _
        ]

Local $ret

For $i = 0 To UBound($aURLS) - 1

    $ret = Ping($aURLS[$i], 250)
    If $ret = 0 Then
        Switch @error
            Case 1
                ConsoleWrite('! ret = 1...' & $aURLS[$i] & ' is offline' & @CRLF)
            Case 2
                ConsoleWrite('! ret = 2...' & $aURLS[$i] & ' is unreachable' & @CRLF)
            Case 3
                ConsoleWrite('! ret = 3...' & $aURLS[$i] & ' is a bad destination' & @CRLF)
            Case 4
                ConsoleWrite('! ret = 4...' & $aURLS[$i] & ' other error' & @CRLF)
        EndSwitch
        ContinueLoop
    EndIf

    ConsoleWrite('+ ' & $aURLS[$i] & ' reached in ' & $ret & ' milliseconds' & @CRLF)

Next

note - the timeout is so short (250 ms) that sometimes valid websites are reported as unreachable
