Clonning CentOS 6.2 in VirtualBox

Posted by ePlus on February 27, 2012 No comments

Step 1

Install, update & configure your new CentOS installation. I wanted to install the Virtualbox Guest Additions and I recommend that you do the same due to the extra drivers and extensions it installs as it will make it easier later on (seamless mode and you don’t have to RIGHT CTRL every time you want to click outside the VM)

To install the Virtualbox Guest Additions do the following:

Ubuntu Mediawiki Move LocalSettings.php Fix

Posted by ePlus on January 16, 2012 No comments

If you have just installed Mediawiki from its .deb package and you get the below message:

Then all you have to do is move the the LocationSettings.php file:

 sudo mv /var/lib/mediawiki/config/LocalSettings.php /etc/mediawiki

Refresh the page and it should all work nicely!

Auto Mount SMB/CIFS Shares Ubuntu 11.10

Posted by ePlus on January 14, 2012 No comments

If you are always accessing network shares from your Linux desktop you might find it easier to have those shares automatically mounted at login.

This can be achieved like so on a Ubuntu installation:

Step 1

First we’ll add our remote SMB/CIFS share information to the /etc/fstab file:

sudo nano /etc/fstab

And at the end of the bottom of the fstab file add the following:

//YOURSMBCIFSSHAREIP /media/YOURSMBCIFSSHARE smbfs credentials=/home/YOURUSERNAME/.smbcred,gid=users

Simply put your SMB/CIFS share IP address and then the desired name that will appear in /media/ as. Then in the next step we’ll create a credentials folder so you’ll want to put in your username in the path there and ultimately we want to allow all users to access this share, so we add the users group.

Step 2

Now create a credentials file in your home directory /home/yourusername

 nano ~/.smbcred

And add the following in the newly created file:

username=YOURSMBUSERNAME
password=YOURSMBPASSWORD

Now you don’t have to create the .smbcred file if authentication is disabled on your share. You can leave the fields blank or remove credentials=/home/YOURUSERNAME/.smbcred.

Update Ubuntu 11.10 to Kernel 3.2

Posted by ePlus on January 6, 2012 No comments

So you want to take advantage of the new features the new version of Kernel 3.2 has to offer? Fear not, simply copy and paste the below commands and you’ll be good to go!

Some of the main features along with many others of 3.2 are:

Ext4 now supports block sizes up to 1MB, which decreases the time spent doing block allocations.
Btrfs delivers detailed curruption error messages, so instead of something like ‘block xyz is bad’ you get this:
btrfs: checksum error at logical 5085110272 on dev /dev/sde, sector 2474832, root 5, inode 32583, offset 0, length 4096, links 1 (path: default/kernel-0/Makefile)
Lots of filesystem performance improvements.
A process scheduler divides the available CPU bandwidth between all processes that need to run.
Inclusion of a TCP “Proportional Rate Reduction” algorithm, developed by Google, which improves latency and the time to recover.
Support for transmission of IPv6 packets as well as the formation of IPv6 link-local addresses and statelessly autoconfigured addresses on top of IEEE 802.15.4 networks.

I am always finding myself searching for Romanian Sopcast TV channels. Here is a list of some of the popular Romanian channels, plus some others:

Windows XP SP3 & 7 SP1 Disabling Safe Services

Posted by ePlus on December 15, 2011 No comments

I frequently have to tweak and optimize the operating systems that I work with. And one of the things that I do as part of my check list is to disabled unnecessary services that are safe to do so which won’t impact usability of the desktop.

The lists of services which are to be disabled was taken from Black Viper’s resourceful website.

Save the following as a batch file and run it.

Windows XP SP3


net stop Alerter
net stop ClipSrv
net stop HidServ
net stop Messenger
net stop NetDDE
net stop NetDDEdsdm
net stop RemoteAccess
net stop ERSvc
net stop cisvc

net stop RemoteRegistry
net stop seclogon
net stop SCardSvr
net stop LmHosts
net stop TlntSvr
net stop UPS
net stop WebClient
net stop W32Time
net stop WmiApSrv

Windows 7 SP1


net stop RemoteAccess

Xubuntu 11.10 & USB Headset Workaround

Posted by ePlus on December 12, 2011 No comments

So you got yourself Xubuntu 11.10 installed and now want to Skype with your USB headset. Great, so you plug in your headset into the USB port, start Skype call a friend (or the test call bot) and BAM – audio out from the speakers and no mic recording in sight! You scratch your head… You dig around the ALSA mixer but nothing, no matter how many “Controls” you select it just wouldn’t happen and this is why ladies and gents Linux is still a basement level 10 paladin player toy OS to brag about on forums.

Xubuntu 11.10 & Redshift Howto

Posted by ePlus on December 12, 2011 No comments

Following on from my previous rant/workaround in getting your USB headset to work, it is time to save our eyes by configuring “Redshift. As the developer puts it:

Redshift adjusts the color temperature of your screen according to your surroundings. This may help your eyes hurt less if you are working in front of the screen at night. This program is inspired by f.lux (read here for the reason why I started this project).

In my case, simply installing it via “Ubuntu Software Center” didn’t work, why should it? It would be too easy then, so anyway.

Scheduling sFTP Transfers with PSFTP

Posted by ePlus on November 25, 2011 No comments

Recently I was asked by a client to implement some sort of system that will establish a sFTP connection to a remote server and download the desired data. Initially I was like, yeah easy, get a sFTP FOSS client, configure it with the remote servers’ details, schedule it and done!

Well… Wasn’t I in for a surprise!!! Turns out that there isn’t really any nice, simple GUI software which can be scheduled and off we go. Nope, CLI all the way baby! Of course, there is Filezilla which can establish sFTP connections and other FTP software around, including cuteFTP but for that you have to pay, and you know… I like my FOSS, so I didn’t really want to go down that route.

So I finally settled for PSFTP – Putty sFTP client, after reading up its short but comprehensive manual I got it working the way I wanted it to like so:

Posted by ePlus on November 14, 2011 No comments

In the this tutorial we will be going through deploying a OpenVPN Access Server (AS) from scratch in a VMWare ESXi 4.1 environment. This should be perfect for a home VPN server (due to licence limitations of a maximum of 2 users being connected at the same time)!

Good luck and read on!
