I have two different servers (A and B, both are Windows) and I am executing putty via command line between them. Server A executes remotely an script in server B and everything works fine, but I am not able to get the output (ERRORLEVEL) in server A once the script has been executed in server B. I mean, I can get the output but always says that the process has finished successfully even if the process in server B has failed.

I attach an small example of the process (ExProcess.bat) I have in server B:

set LOG_PATH=C:\Project\Logs
set BIN_PATH=C:\Project\bin

echo %date% %time% >> %LOG_PATH%\logfile.txt
if not %ERRORLEVEL%==0 exit %ERRORLEVEL% 

And this is how I am making the remote call from server A:

putty -ssh server02 -P 22 -l user1 -pw password1 -m C:\Project\SSH_PRG0001_CMPG0001.txt

SSH_PRG0001_CMPG0001.txt contains the remote batch (C:\ExProcess.bat)

If I execute in Windows Command line %ERRORLEVEL% once I have executed the putty command I am not getting the correct output of the process I have run remotely.

I have checked that the remote process is returning the correct output error in server B, but my problem is that I cannot get this output from server A.

Thanks for your help

As you're discovering, this won't work.

%ERRORLEVEL% (which is not, in fact, "output", but rather a function of the local shell) returns the status of the last command executed; on server B, that's EXECUTE_MY_COMMAND, as you want it to be -- but on A, it's instead putty! Since Putty successfully connected and did its thing, %ERRORLEVEL% is 0, as it should be.

You could modify your script on B to end with something like echo %ERRORLEVEL% (instead of your if statement), then capture that output on A (e.g. via redirection) and react accordingly. Or, whatever it is on A that's responding to the result, you could consider reacting on B instead, making the entire process entirely self-contained on server B and merely triggered by the connection from A.

Thanks for your response. I have added "echo" at the end of the script instead of using the IF statement, but when I try to redirect the output to a flat file it doesn't write anything. For example: putty -ssh server02 -P 22 -l user1 -pw password1 -m C:\Project\SSH_PRG0001_CMPG0001.txt > C:\file.txt Thanks –  Jesus Mar 25 '14 at 20:04
When you run it without the redirection, do you see the expected output? –  Kromey Mar 25 '14 at 20:12
I see that the process fails and it writes 1 (echo 1 when fails), but I cannot get this error from the server that is making the remote call –  Jesus Mar 25 '14 at 23:00
