snapin and batch script

Avaryan

Based on a couple minutes of research, I don’t think you can run UpdateInstaller.exe silently. So this is likely just not going to work.

UpdateInstaller.exe

is only for testing, the command i want to launch is :

"call W:\cmd\DoUpdate.cmd /verify /updatecpp /updatetsc /instdotnet4 /autoreboot"

from the samba share

Tom Elliott

@plegrand Does the “DoUpdate.cmd” script call UpdateInstaller.exe?

plegrand

@Tom-Elliott no
It works alone without waiting something from the user

Tom Elliott

@plegrand So have you tried with using the DoUpdate.cmd instead of trying with UpdateInstaller.exe?

plegrand

@Tom-Elliott @Avaryan
It works !!! with psexec
for the moment from command line, then i need to package my script and psexec ?

here is the command :

psexec \\%computername% -u %computername%\Administrateur -p password -e cmd /c "net use y: \\samba\wsus$ "my'password" /User:samba\Administrateur & y:\wsusoffline\client\UpdateInstaller.exe"

UpdateInstaller.exe open a windows and wait for user input.
For the moment i dont if it will works with snapin

plegrand

@plegrand yes
but for the moment nothing happen
I’m trying snapin pack
with this command :

psexec \\%computername% -u %computername%\Administrateur -p password -e cmd /c "net use y: \\samba\wsus$ "my'password" /User:samba\Administrateur & y:\wsusoffline\client\cmd\DoUpdate.cmd /verify /updatecpp /updatetsc /instdotnet4 /autoreboot"

i made a zip with my batch script (test.bat) and psexec

Snapin Pack File cmd.exe
Snapin Pack Arguments /c “[FOG_SNAPIN_PATH]\MyScript.bat”

@plegrand You know, most people just keep their images updated so they don’t have to worry about this so much. I know some of the community do quarterly images while others do annual images.

You’d probably have better luck just opening an Amazon Web Services account and installing Systems Manager into your image so you can control patching through AWS. This tool is specifically built for this, among a few other things.

Or, just a WSUS server and some group policy to control how updates work.

I cant make it works for the moment with snapinpack, I’ve got an error that i don’t understand :

An idea ?

@plegrand
It seams that i have to create the zip file on windows , on linux i have this error.
After that the snapin pack is launched but i think it’s waiting interaction with user and even i use psexec the script is launch by system. Then it doesn’t works.
I have to find an other solution

Quazz

Psexec needs the EULA to be accepted on first use (I’m guessing per user basis even)

So add -accepteula maybe.

edit: But given you only to execute commands on the local system as a different user, runas is likely the easier/better tool for the job.

edit2: Just remembered you can’t pipe passwords to it, nvm

plegrand

@Quazz
I think the problem is that snapin is launched as SYSTEM user, then even i use psexec or runas to run command as local user, snapin is launched as SYSTEM and then it does not works. I try with -accepteula but …

@Avaryan @Tom-Elliott @Quazz @Wayne-Workman
May be someone know a solution to launch remote command on mulitple computers without GPO’s ?

@plegrand PDQ Deploy?? https://www.pdq.com/pdq-deploy/

We use this tool instead of FOG Snapins to deploy applications in our offices. They have a free version that should do what you need, but the paid for version is reasonable in cost and well worth the price because of the additional functionality.

Avaryan

So, the overall objective here, is it just to get Windows updated? Does it have it be offline using wsusoffline?

There are PowerShell modules for Windows Update that may be able to trigger updates.

This is not a problem, this is by design. Not only is it by design in the FOG Client, it is by design from Microsoft. This is how deployments are made safe, anything less is a breach of security.

I already said it, Systems Manager from Amazon Web Services.

plegrand

@Wayne-Workman I understand that

plegrand

@Wayne-Workman Not sure i want to use Amazon service

@Wayne-Workman @Avaryan @george1421 @Quazz @Tom-Elliott

Just for information :

I found this tool :
https://github.com/CoreSecurity/impacket/tree/impacket_0_9_13

There is this script inside : “psexec.py”

The package exist for debian : Package python-impacket
psexec.py works fine from the linux command line (very long command line )

And i think i will be able to use it on several remote windows computers with tmux.
