Hello!
I have two 4-Day Tickets to LinuxTag. If someone like to go, please make your comment with email address.
Ich habe 4-Day Tickets für LinuxTag. Wenn jemand gerne gehen, Sie bitte einen Kommentar mit E-Mail-Adresse machen.
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.
Some links about Grub:
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.
I bought a cheap webcam called C3Tech to talk with my family. But, when I installed openSUSE 11.2, I can’t work with that. Solution? Use Video4Linux to solve this.
Some data about webcam:

## dmesg when I put the webcam on the usb port.

And now we will install the C3tech camera.
1 – First, add we add webcam repo on YaST.
2 – Search for v4l libs and devel and install it. Install linux development packages also(make, gcc, bison..) Install mercurial also.
3 – Clone the last version of V4Linux drivers to your desktop, using hg.
hg clone http://linuxtv.org/hg/v4l-dvb
4 – Enter on v4l-dvb directory and compile the source.
cd v4l-dvb
make && make install
5 – If you have errors, please check linux development packages, we will need it to compile using make.
6 – Ready! Now we will use LD_PRELOAD prefix to run some camera programs, like skype and cheese.
To skype, you can try a shell-script(create a file using your prefered text editor, add the content below and add basic permissions to execute):
#!/bin/bash
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype
To cheese, the same stuff, just change the program name in the end of PREFIX line.
#!/bin/bash
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so cheese.
And now, you can use skype and cheese with v4libs.
ALL THANKS TO DOUGSLAND. HIS WORK TO V4L IS GREAT.
Now, we will test YaST and sharing. Another superficial test: How a user can access YaST and setup printers, keyboard and manage new packages? For example, in a company, a workstation user will need share files… and where is this option? YaST is the answer!
For example, YasT new look
. 
Comment: I found the same YasT style on GNOME. And I like it! All options, concerning Software, Hardware, System.. as part of a list, and when you click in the left menu, YaST just adjust focus to the section. But, If I want to use a option for the last section, I just use the scroll and have fun! For search a specific module, just use the field Search and will be fine too!
Sharing Files with a Samba Server
Comment: Like previous versions of Samba Server administration of YaST2, just click on the module in the section Network Services. YaST2 will ask to install samba server and samba client. After, few dialogs screens to define WORKGROUP and some share… and voilá! Is there an easier way to install Samba using only graphical screen and setup it?
My first test was: How to simple install a linux desktop system, and use a workstation, with internet browser, email, IM,openoffice, widgets.. I did the automated install with KDE, follwing all already selected patterns in the installation process.
Its just a superficial review. Looking for news, updates and popular software. I didn’t work extensively with those applications, because its a initial test: Just run the application and check. I will do more extensively tests on those applications, to prevent crashes or another problems.
I changed only the package setup: installed VirtualBox Guest Additions to improve the virtual machine performance and usability.
Desktop Presentation after login – KDE 4.3.1 RC1
Comment: Beautiful! Quick start and new wallpaper. Surprises! I love this!
Desktop Presentation – Menu
Desktop Presentation – My Computer
Comment: Nothing different than older versions to me(first impression)
Desktop Presentation after login with widgets
Comment: No surprises. Widget is a feature from KDE 4. But, we have a lot of new widgets, like Remember the Milk, Twitter, Identi.ca and much more! Work and follow some important tasks and some twitter updates from our friends. I like lancelot, which I didn’t know it!
IM and Twitter
Comment: Lovely! I just added my gtalk account and works! Perfectly! Without additional setups. Kopete works stable, without crashes. Twitter widget have some problems with showing updates. I need to close and re-setup twitter account with more updates to show.
Kmail
Openoffice
Few days ago I received nice news. Now I’m part of Test Core Team. I will start with some posts about my tests. The first test will be the Automated Installation, with minimum setup, using Virtualbox. The same test with a real machine, on my Macbook Black, 4GB RAM.
We have a lot to do, and I`m so glad to participate of Test Core Team. Its a great opportunity to test, give a lot of feedback and help to improve the distribution which I had been working since 1999.
Later!
For all test team which started to develop tests, running openSUSE 11.2 M7 in Virtualbox:
To install Virtualbox Guest Additions…
- Using YaST >> Software Management, select the view Patterns and choose Development Packages(like gcc, make and another kernel compiling stuff) and search for kernel-default-devel package. Install both and after run the installer *.run of Virtualbox Guest Additions.
