batch file for sporadic internet connection - file

i've seen pingers and auto redials when theres a request time out.
problem:
but im having a hard time researching the 'counter or increment' part.
idea:
heres how it should be:
start pinging continuously while connected to internet,
otherwise
count (or accumulate) request time out until 1min or 60 request time out,
if connection went back after request time out & less than '60 times request time out',reset the
'request time out counter' to zero
if request time out reached 60x :
run another batch or reconnect re-dial up.
loop to internet connection pinging
the closest that i saw:
(but for some reason its not working on my xp)
#echo off
setLocal EnableDelayedExpansion
:loop
ping -n 2 10.174.10.48 >> log
find /i "Reply" < log > nul
if not errorlevel 1 type nul > log & goto :loop
for /f "tokens=1" %%a in ('find /c /i "Request timed out" ^< log') do (
if %%a geq 10 echo file.exe && type nul > log
)
goto :loop

thank you

It would be good to know why the above script is not working. Because possibly other solutions will also not work. If you use a non-English version of windows, you need to replace the text "Reply".
I think the following should work. It just implements the counter. But you can try yourself how you need to set the counter to execute the script after 60 seconds.
#echo off
:reset
set count=0
:loop
ping -n 2 10.174.10.48 | find /i "Reply"
if not errorlevel 1 goto :reset
set /A count=%count%+1
if %count% lss 100 got :loop
call reconnect
goto :reset

Why is this CMD .bat file stopping?

I've written a simple .bat file to monitor the ping between my PC and Google (in an attempt to monitor roughly the health of the network, and record any dropouts).
The following is in a file called Pingtest.bat
#ECHO OFF
:LOOPSTART
FOR /F "tokens=* USEBACKQ" %%i IN ('%DATE:~0% %TIME:~0,8%') DO (SET "TIMED=%%i")
FOR /F "tokens=* USEBACKQ" %%g IN (`ping -n 1 -w 10000 www.google.co.uk`) do (SET "PING=%%g")
FOR /F "tokens=3 delims=," %%a in ("%PING%") do (set AVG_PING=%%a)
SET AVG_PING=%AVG_PING:~11,-2%
set /a varCheck=%AVG_PING%
IF %VarCheck%==%AVG_PING% (goto :OUTPUT) else (goto :ERROR)
:ERROR
SET AVG_PING=ERROR
:OUTPUT
SET OUTPUT=%TIMED% %AVG_PING%
echo %OUTPUT% >> Pingtest.txt
set "TIMED="
set "PING="
set "AVG_PING="
set "varCheck="
timeout /t 5 /nobreak > NUL
GOTO LOOPSTART
Every 5 seconds, this outputs a timestamp and the ping result in ms (e.g. 23/07/2021 23:35:40 15) and appends it to the Pingtest.txt file. This should run indefinitely.
This .bat file is executed via a .vbs file which executes the .bat silently (code from this post), executed at startup.
The issue is that I would expect this code to run indefinitely until the user session ended (shutdown/logoff), but the code seems to stop on its own after ~350 executions (~30 mins). Is there a reason for this, and can this by bypassed/resolved such that the code can run indefinitely?
P.S. Fully aware this is is probably awfully-written code, so open to any feedback/improvements.
Thanks
IF %VarCheck%==%AVG_PING% (goto :OUTPUT) else (goto :ERROR)
This is the core of the issue. If the DNS lookup or ping outright fails, VarCheck ends up being empty, then this line is parsed nonsensically, and the end result is the rest of the batch file is ignored. Changing it to something like:
IF [%VarCheck%]==[%AVG_PING%] (goto :OUTPUT) else (goto :ERROR)
Will handle the case where VarCheck is empty.

Msgbox to prompt user if job (printing) is skip in batch

As suggested in my previous question, 1 question per thread. So Im here to open another question. Basically I want to prompt user that printing will be skip today because nothing to print, then the user will press OK, then code will continue to shutdown the computer. I want to do this to alert user that today's printing job have been run.
So I try some code like below, it seems working but i dont know how to implement in my main code.
#echo off
Call :Msgbox
if "%errorlevel%"=="1" GOTO SHUTDOWN
exit /b
:Msgbox
echo wscript.quit MsgBox ("Printing skipped.. Press ok to shutdow the computer", 48, "Shutdown Computer") >"%temp%\input.vbs"
wscript //nologo "%temp%\input.vbs"
exit /b
:SHUTDOWN
echo "%SystemRoot%\System32\shutdown.exe -s -t 60"
PAUSE
This is part of my main code where i want to place above code.

How to play sound if phone connects to network?

I try to write a little batch script. It should play a sound if my phone joins my network.
#echo off
:A
ping -n 1 xxx.xxx.xxx.xx | findstr TTL && start airsiren.wav
goto A
The problem is now that if the phone is detected, it repeatedly starts the sound. But it's supposed to just play once.
Does anyone know a simple fix? Maybe with an IF condition?
I haven't been doing much with batch, but I think I got some basic knowledge.
I suggest following code:
#echo off
set "LastExitCode=1"
:Loop
%SystemRoot%\System32\ping.exe -n 1 xxx.xxx.xxx.xx | %SystemRoot%\System32\find.exe /C "TTL" >nul
if not %ErrorLevel% == %LastExitCode% set "LastExitCode=%ErrorLevel%" & if %ErrorLevel% == 0 start "Play sound" airsiren.wav
%SystemRoot%\System32\timeout.exe /T 5 /NOBREAK
if not errorlevel 1 goto Loop
PING outputs a line with TTL if there is a response on echo request and exits usually with value 0 on receiving a response and with 1 on getting no response. But PING does not always exit with 0 on a positive response which is the reason for using FIND.
FIND processes the output of PING and searches for lines containing the string TTL. FIND exits with value 0 on finding at least one line with TTL and otherwise with 1 for indicating no line found containing the search string. The output of FIND to handle STDOUT is of no interest and therefore reduced to a minimum by using option /C and redirected to device NUL.
Now the exit code of FIND is compared with an environment variable which holds last exit value of FIND initialized with value 1.
On current exit code being equal last exit code, there is no change in availability of the pinged device on network and therefore nothing to do.
Otherwise on a difference the current exit code is assigned to the environment variable for next loop run and current exit code is compared with value 0. If this second condition is true the pinged device sent the first time a positive response on echo request by PING. In this case the sound is played.
There is nothing else done on pinged device not available anymore on network, i.e. the exit code changes from 0 to 1.
Then a delay of 5 seconds is started using TIMEOUT with giving the user to break it with Ctrl+C. This reduces the processor core usage giving Windows the possibility to use the processor core for other processes and also reduces network usage when the pinged device is available at the moment on network. And of course the pinged device does not need anymore to permanently response on echo requests.
A jump to label Loop is done if TIMEOUT exited normally without a user break. Otherwise on user pressing Ctrl+C the batch file processing also ends.
TIMEOUT with parameter /NOBREAK requires Windows 7 or a later Windows version.
For understanding the used commands and how they work, open a command prompt window, execute there the following commands, and read entirely all help pages displayed for each command very carefully.
echo /?
find /?
goto /?
if /?
ping /?
set /?
start /?
timeout /?
See also single line with multiple commands using Windows batch file for an explanation of operator & and meaning of if not errorlevel 1.
This can be fixed very easily using %errorlevel% and an IF statement.
Original script by Jelle Geerts.
#ECHO OFF
:Search
ping -n 1 "xxx.xxx.xxx.xx" | findstr /r /c:"[0-9] *ms"
if %errorlevel% == 0 (
echo Device was found!
start airsiren.wav
pause.
) else (
goto Search
)
My solution:

There are two problems with your code
Your code will unconditionally goes to the beginning even after the phone is connected, so it repeats playing the sound. You could use ... && (start airsiren.wav & goto :EOF) to terminate the batch file or use another label other than :EOF to do something else. But this doesn't give you the option to keep monitoring the phone for disconnection and re-connection.
You have to check the setting of the default media player (Typically Windows Media Player) and make sure that it is not set to continuously loop or repeat the media. Also it is overkill and somewhat inconvenient to launch a full fledged media player just for playing back a short notification sound, and usually you have to close the media player afterwards.
So this is the code I propose which solves the above mentioned obstacles by providing the option to continuously monitor the phone's connection status and also provide a more programmatic way to play the notification sound in a self contained player by using a hybrid BAT/JSCript solution.

Better way to use findstr to get packet loss, batch

Looking to use findstr to get it to find "0% loss" after a ping command.
Perhaps an array of anything up to "50% loss".
This is for checking and ensuring a connection to the internet is 100% established before launching something online.
Currently it's structured:
ping %ip% -n 3 -w 3000 | findstr "0% loss"
pause
goto Starting
It's currently ignoring findstr and no matter what it refuses to find what I'm looking for
Ideally it would flow like:
ping %ip% -n 3 -w 3000 | findstr "0% loss" || goto Echo
pause
goto Starting
:echo
Could not find "0% loss"
pause
And I have tried that, it will go to echo, but even with 100% connection so it's clearly just not operating how I'd like it to.
Is there a better way to find % packet loss?
Or
Is there a better way to test internet connection, given ping doesn't work when a device is totally offline.
The search string you are looking for is too broad. When you check findstr for "0% loss", you are inadvertently picking up "100% loss" as well. Fortunately, ping puts the packet loss in parentheses, so you can simply include the open parenthesis in the search string.
#echo off
title Restart
color 0A
cls
:start
Cls
set ip=www.google.com
:Pingcheck
echo Checking ping..
timeout /t 3
ping %ip% -n 5 -w 3000 | findstr /C:"(0% loss" || goto Loss
pause
:NoLoss
echo We found 0 packet loss, at %ip% on %date% at %time%
pause
goto start
:Loss
echo We found some packet loss.
pause
I've also changed the name of the :Echo label because echo is already a command and having it also be a label would be confusing.
You can also check ping status with wmi. The advantage to this method is that it'll goto :fail on the first failure, and not continue its lost cause of completing 5 ping attempts, while also providing a simple way to preserve the average response time. It uses set /a to check whether the result of the wmi query contains a numeric value. If it does, pass. If not, fail.
#echo off & setlocal
set "host=www.google.com"
echo Pinging %host%...
for /L %%I in (1,1,5) do (
for /f "delims=" %%x in (
'wmic path win32_pingstatus where "address='%host%' and timeout=3000"^
get ResponseTime /value ^| find "="'
) do (
2>NUL set /a "%%x, avg += ResponseTime" || goto fail
)
)
set /a "avg /= 5"
echo 0%% packet loss. Woo. Average response time was %avg%ms.
exit /b
:fail
echo Aw snap. Packet loss.

batch file timeout command jumping to 10k, 30k, 40k seconds

I'm currently running a set of commands that utilizes the timeout function in my batch files. The timeout function uses a variable for how many seconds it should pause, and I think that may be causing issues, but I desperately need it to function properly.
I've got an update to my question which details more about what may be happening.
I used some suggestions that I had in the comments to try and fix my script, but it did not work.
Here is my script:
:connectToTheInternet
setlocal EnableDelayedExpansion
set timeout=2
echo checking internet connection
echo.
:connectToTheInternetRestart
ping -n 1 google.com | find /i "TTL=" >NUL && (
echo Internet connection already established, checking script versions.
echo.
goto scriptVersion
REM toupd
) || (
if "%COUNTER%"=="0" (
echo Creating wifi profile.
echo.
set /A COUNTER=1
goto createWifiProfile
)
SET /A "tries = (%COUNTER%-1)+1"
REM if failed endonfail times, give up
if "%COUNTER%"=="%endonfail%" (
echo Error: Could not connect to network %tries% times, stopping script.
echo.
goto endNoShutdown
)
echo.
echo Attempt #%COUNTER%.
echo.
REM raise waiting time between connections
SET /A "modulo = (%COUNTER%-1) %% 2"
if "%modulo%" EQU "0" (
set /A timeout=timeout+2
echo failed %tries% times in a row. Increasing wait time between actions to %timeout% seconds.
set /A COUNTER=COUNTER+1
) else (
set /A COUNTER=COUNTER+1
)
REM disconnect existing network
netsh wlan disconnect
netsh wlan delete profile name="%wifissid%"
timeout /t 1 /nobreak
echo.
REM attempt connection
netsh wlan add profile filename="connect.xml"
netsh wlan connect name="%wifissid%" ssid="%wifissid%" >NUL
echo.
echo Wait time is currently !timeout! seconds.
timeout /t !timeout! /nobreak
echo.
REM check pings
ping -n 1 google.com | find /i "TTL=" >NUL && (
echo Successfully connected. Checking script version.
echo.
goto scriptVersion
) || (
set /a COUNTER2=COUNTER+1
echo Connection attempt failed. Starting attempt #%COUNTER2% in 3 seconds.
echo.
timeout /t 3 /nobreak
cls
goto connectToTheInternetRestart
)
)
My problem is specifically the timeout /t !timeout! /nobreak which should wait for a variabled amount of time. The problem is, sometimes (it only happens when the device successfully connects to the internet, but not every time the device connects to the internet) the timeout jumps up to 10,000 seconds, 30,000 seconds or some other random high number (And they really are random, I've seen some at like 12,536 seconds.) When it should always be less than 12 based on the timeout variable. Yes, I mean seconds NOT milliseconds. As you can imagine, there is a big difference between 10k seconds (roughly 21 days) vs 10 seconds.
I have no idea what could be causing this, or how to solve it and would love some help.
Here's a left-field thought, brought about by your comment
(it only happens when the device successfully connects to the internet, but not every time the device connects to the internet)
Before it connects to the internet, is the date, time and timezone correct? Connecting will synchronise the time - which may muck up your timeouts!
Like I said: left-field, but...
choice seems not to be affected by the mentioned behaviour of timeout: "when changing the time from another cmd window while running a timeout 300, the "waiting for ..." prompt indeed changes the remaining time accordingly".
So instead of timeout /t !timeout! you can use
choice /n /c yn /d y /t !timeout!
/c yn is just for making it language independent.
