How much of the batch file have you done?

[Knighter]

Hi !! i have done only the delete command ( del C:\Users\Desktop\pollo.txt ) but i think how i can do the verify ,
if net user XXX password
if [NOT] password==hello
if DEFINE password==hello

but these are wrong :/

it's possible to make in dos ?

You wrote net user and I'm wondering: are you are referring to the password when someone tries to log onto the account when Windows starts up?

[Squashman]

You cannot verify a users Windows password like that. The passwords are encrypted in the sam database.

Give this utility a try.

Yes foxi i referring to the password when someone tries to log onto the account when Windows starts up

Squash i tries the Auth tools , in cmd the command Usage: Auth.exe /d:dom /u:uid /p:pwd auth /?

but when i write auth /u:XXX the message is :
Auth V01.01.00cpp Joe Richards August 2001
Usage: Auth.exe /d:dom /u:uid /p:pwd

You need to supply the computer name, username and password.

[Squashman]

Code: Select all

C:\Batch>auth /d:%computername% /u:Squashman /p:CorrectPassword

Auth V01.01.00cpp Joe Richards (joe@joeware.net) August 2001

Authenticating COCO\Squashman
Logon Successful.

C:\Batch>auth /d:%computername% /u:Squashman /p:WrongPassword

Auth V01.01.00cpp Joe Richards (joe@joeware.net) August 2001

Authenticating COCO\Squashman
Logon failure: unknown user name or bad password.

Ok it's work : Logon Successfull
but how i can use it for my scope ? xD

if auth /d:XX /u:XX /p:hello
del C:\Users\XX\Desktop\pollo.txt

Mmmm no dont work xD

[Squashman]

A couple of options but I think the easiest would be checking the errorlevel.

Code: Select all

C:\Batch>auth /d:%computername% /u:Squashman /p:CorrectPassword >nul 2>&1

C:\Batch>echo %errorlevel%
1

C:\Batch>auth /d:%computername% /u:Squashman /p:WrongPassword >nul 2>&1

C:\Batch>echo %errorlevel%
0

[Knighter]

But the error level would create when the bath file are start and are ever 1

cd C:\Users\XX\Desktop\ auth /d:%XX% /u:XX /p:hello >nul 2>&1

echo %errorlevel%

cd C:\Users\XX\Desktop\ auth /d:%XX% /u:XX /p:help >nul 2>&1

echo %errorlevel%

if ERRORLEVEL 1 GOTO End
:Error
del C:\Users\XX\Desktop\pollo.txt
:End
pause

in this mode if i insert the wrong password at login the pollo.txt file aren't deleted because the command "auth /d:%XX% /u:XX /p:hello" return errorlevel = 1

[Squashman]

I was giving you examples of what the errorlevel is when the command is sucessfull and when it is not successful. You dont need to run it twice in you batch file.

[Knighter]

Ok , but what i do ?

if i use only one ( this ) , the error level are 1 and goto end

cd C:\Users\XX\Desktop\ auth /d:%XX% /u:XX /p:hello >nul 2>&1

if ERRORLEVEL 1 GOTO End
:Error
del C:\Users\XX\Desktop\pollo.txt
:End
pause

and if i use only one ( this ) , delete the file

cd C:\Users\XX\Desktop\ auth /d:%XX% /u:XX /p:help >nul 2>&1

if ERRORLEVEL 1 GOTO End
:Error
del C:\Users\XX\Desktop\pollo.txt
:End
pause

i dont undestand how i can apply to login, the user enter the correct password ( in login windows ) ? ok , do nothing
the user enter the wrong password ? ok , delete the file

how i can apply this ?

[Squashman]

You cant apply this to the Windows login screen. There is no way to capture the password they typed in to the Windows Login screen and pass it to the batch file. If they cant login how do you expect a file to be deleted?
