Ping command and errorlevel

[SvenBent]

Im trying to go through at list of computer in batch file to verify they are up and running.
Im using this little batch snippet for it.


@echo off

for /F "tokens=*" %%A in (computerlist.txt) do (
ping /n 1 "%%A"
if %errorlevel% == 0 echo %%A online
if %errorlevel% == 1 echo %%A offline
)

however it seems to always report back "online"
Ive tried putting in echo %errorlevel% right after the ping command and it always response 0

however if i ctrl+c'ed a previously batch run and run the batch again withing the same command box. Its reports -1047something something

What am i doing wrong ?

try this

@echo off
setlocal enableextensions enabledelayedexpansion

for /f %%i in (PCS.TXT) do (
   SET bHOSTUP=0
   ping -n 2 %%i |find "TTL=" > NUL && SET bHOSTUP=1
   IF !bHOSTUP! equ 1 (
      CALL :HOSTUP %%i
   ) else (
      CALL :HOSTDOWN %%i 
   )
)
GOTO EOF

:HOSTUP
echo Host UP %1
GOTO EOF

:HOSTDOWN
echo Host DOWN %1
GOTO EOF

:EOF
exit /B
