Sorry for an MS post. But I challenge who NEVER worked with windows clients and servers.
Well, this post its about WSUS and “How to change remotely Regedit from Clients”. This is an neeeded step to networks which don’t use Windows Update and have a local server with all updates to local clients. We need to change the regedit from clients to make a link between clients and the local updates server WSUS.
We need first Pstools.
After, we need and script to execute a command remotely: Psexec. This command comes with Pstools. We will use a for to read a file, line by line and apply the regedit keys.
Create a file with clients names, just a client per line. And I put an errorfile in the end, to check some running problems.
@Echo Off
for /f %%a in (file_with_clients_names.txt) do (psexec \\%%a -u DOMAIN\USER-p -e cmd.exe /c “reg import \\UNC_PATH.reg”) 2> errorlog.txt
Cool? Please test first before execute!! Any feedback, comments.
Well, I posted a tutorial about clones, and who never forget some steps making a clone? After the end of the cloning process, grub just say “no way” for you. Important: just for cases which grub its installed on MBR.
There are many websites talking about specific errors, but I will give some hints which helped me sometimes.
Frequent Error: its the “Error 2″ on the stage 1.5 of grub loading. When this error occurs, please check your HDD configuration on FSTAB and MTAB. Normally when we change some old machines which use PATA HDDs to new SATA HDDs, Grub get confused with these devices. After check FSTAB(/etc/fstab) and MTAB(/etc/mtab) after a successful clone process, please pay attention on file device.map, usually at /boot/grub.
If you can’t find it, run grub-install with the option –recheck:
grub-install –recheck /dev/sda
When you execute this command and receive an error with device “hdaxx”, you have to check the configurations on /etc/fstab and /etc/mtab.
Its something simple and appears stupid, but when you are restarting your Linux studies, you lost few hours until discover this kind of problem.

I found an excellent tutorial like a “Howto” to work with NetCat and make clones of HDDs(same size). This tutorial really works, I tested and its on my bookmarks since few days ago.

After 4 months without posts, I’m back. I had been busy, because last December I moved to Germany and my adaptation was so long as I could imagine.
Unfortunately my English its not getting better, because I’m studying a lot of German – and yes, now I can speak Denglish 
and my priority now isn’t study English. But, after 4 months I saw few comments to be approved, and I got some motivation to write about Linux and a bit of Programming too.
And yes working more with Linux, burning my brain with some concepts which I lost after years and years using Linux only as Desktop and small jobs. I have a lot to study! A lot of things to remember, its not big deal or some amazing hacking, but maybe the blog will help me to remember.
Of course, if I have time I will put some materials using German, to help more IT people whom are trying to learn this amazing language to have a chance to work.
As long I can, I will post some articles, and its a little chance which I have to study a bit of English and help someone. If WordPress don’t disturb me with the vocabulary “red lines” at least I’m not so wrong, there are some grammatical problems to resolve, I know.
