Marslert Guy – A walking guy to the M@rs

I’m just awake from a long Zzzzz.

Now, I’m back to post, reply, view blog. Gzeee.

Today, I’m going to share my experience related to title.

Above path is actually the Jailshell configuration path created by WHM when a Cpanel user was granted with shell access.

Note : Do not delete any data inside /home/virtfs/Cpanelusername as it can screw up your Cpanel server.

Reason : The /home/virtfs/ is created for user with Jailshell. Virtfs is hardlinked to some system files. By delete the data inside /home/virtfs/, you delete the actual system file they’re linked to. This is going to be bad and screw up your system file and delete other important data such as Mysql database. So, beware on this.
Shall you need to remove any shell access from any cpanel user, just navigate to WHM >> Manage Shell Access and disable Jailed Shell for users.

For your information, when we check the disk size for /home/virtfs/Cpanelusername. You will see some disk size. Imagine if there is few more cpanel user granted with Jailshell, there will few more directories create at /home/virtfs/. You will find there is more disk space after du -sh those directories. But don’t worry as it will not consume your actual server diskspace. Some advice which is /home/virtfs need to excluded from backup system.

Additionally, always be careful when run command ‘rm -rf *’. It will delete all the file with option of recursive and force. Need more information, visit here.

Hope this sharing could help someone to avoid causing error.

Want to test some new Windows system but not plan to install at production machine or current use machine? Try on a free virtualization tool, Microsoft Virtual Server 2005 R2 if using Windows system. Personally I try Vmware before, but found that this application is not bad and give a try on it.

A classic banana song to share to cheer up your day.



Lyrics

Day-o, day-ay-ay-o
Daylight come and he wan’ go home
Day, he say day, he say day, he say day, he say day, he say day-ay-ay-o

A beautiful bunch a’ripe banana
(Daylight come and he wan’ go home)
Hide thee deadly black tarantula

(Daylight come and he wan’ go home)

Last 3 days, I had the Window Server 2008 First Look training trip at GuidanceView.

Well, I can say that this is a nice training which include clinic that has hands-on labs to test on Window Server 2008. The trainer is nice which I like the course. By having 2 years beginner level experience on Window Server 2003, I able to know the some feature improve from previous version. As know that Win2k8 still under Beta version and it has approximate 75 days to launch the full release version. All the material I took during training still in pre-release version. Lolz. Thats true for it and there will be another official training after this great product launch. Yes, you can always check the launching date at here.

Of cause, there are a lot stuff which need to expose in-depth.

Shall you need some first look to Win2k8 great feature, do visit Microsoft and download free e-learning pdf file. P/s : A msn account need when register for free e-book.

dpkg was interrupted, you must manually run ‘dpkg –configure -a

How we get this error? It could be there is any interruption when running apt-get update.

Based on my understanding, I have installed some broken program. I need to reconfigure the last broken installed program.

This is the magic word can use to fix this problem,

sudo dpkg –configure -a && sudo apt-get -f install

Somehow, my root partition full even though has 3.7GB disk space. I got this error when update my Ubuntu. So the update command just hang at Terminal and little message prompted me for this

I able to clear some space by this command,

sudo apt-get clean

However, I know there might be some other way which I still looking on. I will keep on share if any update on this topic.

My experience when installed Deluge which I have installed but unable to load it. For first time when load Deluge, it will require to make some configuration adjustment. If there is any error during the configuration. Your Deluge will not able to load.

So, we need to re-configure the setting. But, the previous adjustment config file have to remove.

Deluge config file store at ~/.config/Deluge/ . Just remove Deluge directory and launch Deluge again and you will prompt for the adjustment configure again. You may decide to backup the directory before remove, but will not have problem if delete it

When you have prompted with a message state : You need to have root privileges , when opened an application. There are few ways actually to deal with this,

1. type $ sudo application_name , to run under root user
2. type $ gksudo > a screen will display which you may type the application launch command
3. right click on application properties > Launchers > add gksudo at the command field there. When execute the application next time, it will run under root privileges

Thats it if have some application that require root privileges to do something.

How to get rid if the screen turn to blank when watch movie or etc after 10 minute. Well, I checked that it consider a bug when look at launchpad. But, there is a way to work around by add below line to Xorg.conf,

Section “ServerFlags”
Option “blank time” “0″
Option “standby time” “0″
Option “suspend time” “0″
Option “off time” “0″
Option “screen blank” “0″
EndSection

Try again after restart your system.
