[SOLVED] DELL bios setup package

[seb b]

Hello everyone,

I am trying to create a configuration package for DELL UEFI BIOS using their cctk tool.
Some computers have a BIOS password, others do not. We also don't want BIOS passwords to be transmitted in plain text, so I generated executables using CCT, one that removes the password and one that resets it.

I would like to follow these steps in my WAPT package:

• Check if the password is set

• If so, run the executable that deletes it

• make the scripted changes

• launch the executable that resets the password

The only way I've found to check if the password is set is to cause an error in cctk with a bad password; it then gives me a return code that tells me whether a password is set or not.
My problem is that I can't capture this return code.

When I place my order:

Code: Select all

run (r'"C:\Program Files (x86)\Dell\Command Configure\X86_64\cctk.exe" --numlock=enabled --valsetuppwd=impossiblepasswd'")

I have a CalledProcessErrorOutput (normal) which displays this return code

Code: Select all

Traceback (most recent call last):
  File "C:\Program Files (x86)\wapt\common.py", line 3851, in install_wapt
    exitstatus = setup.install()
  File "C:\waptdev\iut-dell-bios-configuration-wapt\setup.py", line 39, in install
    run (r'"C:\Program Files (x86)\Dell\Command Configure\X86_64\cctk.exe" --numlock=enabled --valsetuppwd=impossiblepasswd', return_stderr=errlist, accept_returncodes=[0,3])
  File "C:\Program Files (x86)\wapt\common.py", line 3630, in run
    return ensure_unicode(setuphelpers.run(*arg,pidlist=self.pidlist,**args))
  File "C:\Program Files (x86)\wapt\setuphelpers.py", line 1066, in run
    raise CalledProcessErrorOutput(proc.returncode,cmd,''.join(output+return_stderr))
CalledProcessErrorOutput: Command '"C:\\Program Files (x86)\\Dell\\Command Configure\\X86_64\\cctk.exe" --numlock=enabled --valsetuppwd=impossiblepasswd' returned non-zero exit status 58.
Output:
The setup password provided is incorrect. Please try again.

I would like to be able to retrieve this exit code (58 and 106 in my specific case) in order to be able to verify my first condition.

I tried a try/except on the command to capture the return code, it works great in pyscripter but impossible to launch a package on the clients.

Code: Select all

# -*- coding: utf-8 -*-
from setuphelpers import *
import subprocess

uninstallkey = []


def ispwddefined():

    try:
        print (subprocess.check_output(["C:\Program Files (x86)\Dell\Command Configure\X86_64\cctk.exe", "--numlock=enabled", "--valsetuppwd=impossiblepasswd "]).decode())
    except subprocess.CalledProcessError, e:
        cctkerrorcode = e.returncode
        print cctkerrorcode

    if (cctkerrorcode == 58):
        print "password configured"
        return True;
    elif(cctkerrorcode == 106):
        print ("no password configured")
        return False


def install():

    print ispwddefined()
    

In the PyScripter environment, launching the execution configuration "install" correctly displays the True or False value as well as the relevant return code.

Code: Select all

Ligne de Commande : install "C:\waptdev\iut-dell-bios-configuration-wapt\WAPT\.."
Using config file: C:\Program Files (x86)\wapt\wapt-get.ini
Installing WAPT files C:\waptdev\iut-dell-bios-configuration-wapt
58
password configured
True

Once the package is in the repository and deployed to a test machine, I get this error:

Code: Select all

UnboundLocalError: local variable 'cctkerrorcode' referenced before assignment

I tried defining the cctkerrorcode variable at the beginning of the ispwddefined() function, and here's something even more curious: the package is successful, and the result is:

Code: Select all

NumLock=Enabled

None

I have the impression that in this case, he doesn't see the cctk error...

I must admit that I'm starting to fall short of what I know how to do...

Does anyone know how to capture return codes in a more basic way?

Thank you in advance for your help.

Seb.

Hello again,

I'm adding fuel to the fire, and I apologize in advance...

I just tested it by running the command that should throw an error, specifying that it should accept return code 58 (a password is defined, you didn't provide the correct one), and there was no error. The return code I'm trying to retrieve is indeed returned to the 'run' command. Is it possible to retrieve this code (easily) into a variable?

Code: Select all

run (r'"C:\Program Files (x86)\Dell\Command Configure\X86_64\cctk.exe" --numlock=enabled --valsetuppwd=impossiblepasswd', accept_returncodes=[0,58])

[htouvet]

The `run` command returns a slightly enriched string...
a returncode attribute gives the return code.

Code: Select all

result = run (r'"C:\Program Files (x86)\Dell\Command Configure\X86_64\cctk.exe" --numlock=enabled --valsetuppwd=impossiblepasswd'")
if result.returncode == 58:
    print('Probleme mot de passe')

[seb b]

THANKS!

Unfortunately, it seems that the result of `run` is not an object but Unicode (I'm not sure of my terminology, I admit) ).

Code: Select all

AttributeError: 'unicode' object has no attribute 'returncode'

I tried directly printing the run command with exactly the same result.

Code: Select all

print (run (r'"C:\Program Files (x86)\Dell\Command Configure\X86_64\cctk.exe" --numlock=enabled --valsetuppwd=impossiblepasswd', accept_returncodes=[0,58]).returncode)

[htouvet]

With wapt 1.7.4, it's Unicode enriched with the attribute...
Which version do you have?

[seb b]

Hello,

we are on version 1.7.4.6229.

[htouvet]

I see the problem...
The `run` command in the Wapt class (the one available in the package's `install` function) is patched to return Unicode (for obscure backward compatibility reasons)
But the setuphelpers.run command returns either unicode or bytes (raw string output from the launched command) with the returncode attribute depending on whether the launched command is in unicode or bytes.

https://github.com/tranquilit/WAPT/blob ... rs.py#L949

https://github.com/tranquilit/WAPT/blob ... s.py#L1075

In your case, you should therefore use the direct run function of setuphelpers:

Code: Select all

import setuphelpers

def install():
    result = setuphelpers.run (r'"C:\Program Files (x86)\Dell\Command Configure\X86_64\cctk.exe" --numlock=enabled --valsetuppwd=impossiblepasswd'")
    if result.returncode == 58:
        print('Probleme mot de passe')

[seb b]

Great!

It works, thank you so much.
Now I just have to do the rest of the package.

Thanks again!

Good morning,
I'm trying to do the same thing as "Seb b" but I can't retrieve the return code with `result.returncode`. I think the installation crashes on the first run with the errors below. When the provided password matches the BIOS password, the script displays "Return code = 0.".

The message in your case is: The setup password provided is incorrect. Please try again with exit code 58

So if you want to catch code 58, I recommend using accept_returncodes:

Code: Select all

result = run (r'"%s" -i cctk.ini --valsetuppwd=password -l c:\dell_cctk.log' %cctk_binaries,accept_returncodes=[0, 3010,58])
if result.returncode = 58:
    print(r"Le mot de passe de configuration fourni est incorrect")

or to switch it to error:

Code: Select all

result = run (r'"%s" -i cctk.ini --valsetuppwd=password -l c:\dell_cctk.log' %cctk_binaries,accept_returncodes=[0, 3010,58])
if result.returncode = 58:
    error(r"Le mot de passe de configuration fourni est incorrect")
