c.haslam Posted July 11, 2013 Share Posted July 11, 2013 I have read in several threads that, if there is no connection, ping() times out after 15 seconds, independent of the value of the timeout parameter. So, to me, ping's timeout parameter is of limited use. Am I missing something? This question arose from calling ping to determine whether my router is connected and working properly: Ping('192.168.0.1',200). I have also read http://www.autoitscript.com/wiki/Interrupting_a_running_function . I am thinking that ping() should be handling the multi-processing, but it appears that it doesn't.

BrewManNH Posted July 11, 2013 Share Posted July 11, 2013 I have read in several threads that, if there is no connection, ping() times out after 15 seconds, independent of the value of the timeout parameter. So, to me, ping's timeout parameter is of limited use. Am I missing something?The help file says 4 seconds is the default, not 15, not sure where you read that.With my network card disabled, the Ping returns in about 5ms with an error code set.I have also read http://www.autoitscript.com/wiki/Interrupting_a_running_function . I am thinking that ping() should be handling the multi-processing, but it appears that it doesn't.That link is for a non-native function, not an internal one, and what do you mean by multiprocessing?

c.haslam Posted July 11, 2013 Author Share Posted July 11, 2013 Many thanks for your reply. Here is my script (which suffers significant delays when I disconnect the PC from the router): expandcollapse popupOpt('TrayIconDebug',1) Do $nRouter = Ping("192.168.0.1",200) $eRouter = @error $nInternet = Ping("www.example.com",400) $eInternet = @error $tit = "Check "&StringLeft(@ComputerName,1)&StringLower(StringMid(@ComputerName,2)&"'s connections") if $nRouter>0 Then $msg = "Connected to the LAN: to the router and back: "&GetMsecs($nRouter) Else $msg = "Not connected to the LAN: "&GetErrMsg($eRouter) EndIf $msg &= @CRLF if $nInternet>0 Then $msg &= "Connected to the Internet: there and back: "&GetMsecs($nInternet) Else $msg &= "Not connected to the Internet: "&GetErrMsg($eInternet) EndIf If $nRouter>0 And $nInternet>0 Then $style = 0 + 64 ; i in circle Else $style = 0 + 32 ; question mark EndIf $ans = MsgBox($style+5,$tit,$msg ) ; retry, cancel Until $ans = 2 ; cancel Func GetErrMsg($err) Switch $err Case 1 Return "offline" case 2 Return "unreachable" Case 3 Return "bad destination" Case Else Return "reason unknown" EndSwitch EndFunc Func GetMsecs($n) If $n= 1 Then Return $n&" millisecond" Else Return $n&" milliseconds" EndIf EndFunc I saw 15 seconds in post #9 in I also met it elsewhere.

guinness Posted July 11, 2013 Share Posted July 11, 2013 If you want to check if you're connected to the network, then there is no need for pinging. Look at _WinAPI_IsNetworkAlive in WinAPIEx (check out the AutoIt beta) plus if you want to know whether you're connected to the Internet, then look at _WinAPI_IsInternetConnected (Vista+).

Moderators JLogan3o13 Posted November 19, 2013 Moderators Share Posted November 19, 2013 c.haslam, have you looked at the example in the help file under Ping?! It word for word does what you're asking, just change the URL to the IP or DNS name of the machine you want to ping. "Profanity is the last vestige of the feeble mind.
