Install terminator in CentOS 6.5 (64bit)

 in GNU/Linux  tagged CentOS / epel / terminator by

We installed CentOS 6.5 (64bit) using this ISO, which we downloaded from http://vault.centos.org/6.5/isos/x86_64/

Once we got the OS started, we executed yum update -y to update all installed packages that were older than the versions in the repositories.
After the update process was complete, we then tried to install terminator using yum.

Executing yum install -y terminator resulted in an error:

Loaded plugins: fastestmirror, refresh-packagekit, security
Setting up Install Process
Loading mirror speeds from cached hostfile
* base: mirror.us.leaseweb.net
* extras: mirror.us.leaseweb.net
* updates: mirror.us.leaseweb.net
No package terminator available.
Error: Nothing to do

To solve the problem we needed to install the Extra Packages for Enterprise Linux (EPEL) repository using yum install -y epel-release.

After the installation was done, we executed yum install -y terminator once more and the installation of terminator succeeded.

Downgrade texinfo on CentOS 7.0 (64bit) to version 4.13

 in GNU/Linux  tagged CentOS / downgrade / texinfo by

Recently we had to download texinfo from version 5.1 to any version less than version 5 series.
We used texinfo version 4.13 which is the latest in the version 4 series.

We were trying to compile some tools using an older version of gcc. Instead of using 4.8.5, we used 4.8.2 to achieve our goal and that caused a problem with some .texi files.

Methodology


#Making sure we are not missing any 32bit libraries since we are on a 64bit machine
yum install glibc.i686 ncurses-libs.i686;
#Download the source code
wget http://ftp.gnu.org/gnu/texinfo/texinfo-4.13.tar.gz;
#Extract the files
tar -zxf texinfo-4.13.tar.gz;
#Navigate to the folder
cd texinfo-4.13;
#Configure the installation and make all necessary checks
./configure;
#Build
make;
#Install
sudo make install;

Downgrade gcc on CentOS 7.0 (64bit) to version 4.8.2

 in GNU/Linux  tagged CentOS / downgrade / gcc by

Recently we had to download gcc from version 4.8.5 to 4.8.2.

We were trying to compile some tools and they required using that older version of gcc.
To compile the old version of the gcc we used the version version that was shipped with the distribution.

Methodology

#Making sure we are not missing any 32bit libraries since we are on a 64bit machine
yum install glibc.i686 ncurses-libs.i686;
#Download the source code
wget http://ftp.gnu.org/gnu/gcc/gcc-4.8.2/gcc-4.8.2.tar.gz;
#Extract the files
tar -xvf gcc-4.8.2.tar.gz;
#Navigate to the folder
cd gcc-4.8.2/;
#Make sure we have all dependencies met
./contrib/download_prerequisites;
#Configure the installation and assign the installation folder to be /usr/local/gcc/4.8.2. Finally make all necessary checks before compilation.
./configure --prefix=/usr/local/gcc/4.8.2;
#Build
make;
#Install
sudo make install;

How to restart or shut down Windows through Remote Desktop 2

 in Windows  tagged remote desktop / restart / shutdown / windows by

Assuming you have the following scenario: you are connected to a remote Windows machine via remote desktop and you need to restart it.
Soon you will realize that there is no restart button on the Start menu to click on….
So.. without that button, how do you restart your machine???

Do not fret as there is a way!

To Restart the remote Windows machine

Press the keys Windows+R on the keyboard together, it will pop-up the run command screen.
In the input line type shutdown /r /t 0 and hit the Enter button to restart the machine immediately.

  • The /r option instructs the machine to reboot
  • The /t 0 option sets the number of seconds to delay before executing the restart to 0 (initiate restart process immediately)

To Shut Down the remote Windows machine

Press the keys Windows+R on the keyboard together, it will pop-up the run command screen.
In the input line type shutdown /s and hit the Enter button to shut down the machine immediately.

To Stop a Shut Down or Restart process

To try and stop a shut down process, type shutdown /a and hit enter, it will attempt to abort the shutdown/restart sequence.
Keep in mind though that there still is a high chance for this to fail.
