How to Remove Kerberos Password in Linux

This is a very rare situation one might face. Suddenly your linux based computer, VPS or server might prompt you to enter Kerberos Password. Same thing happened to me, I don’t remember if I had set kerberos password in the past. I had only updated certain packages. This happened when I tried assign new password to an existing vsftpd user. In this case all I could think of is getting rid of Kerberos password to proceed with my work.

Kerberos password is network authentication protocol which allow nodes communicating over a non-secure network to prove their identity to one another securely. Now to get rid of Kerberos password, all we need to do is removing a package that causes the issue. However this is a security feature that one might use if they are conscious about their data.

To remove Kerberos Password in Linux:

sudo apt-get remove –purge libpam-krb5

This will now remove the kerberos password.

How to Compile and Install a Tar file in Linux

The .tar file format is derived from the phrase “tape archive”. Developers often use this format to compress and distribute their sources. By doing this, they need not worry about the platform, so anyone on any platform can directly compile and install on their computers. This short guide will teach you how to extract an tar file, compile and then install it on any linux distro.

After you download a .tar file, open Terminal and navigate to the directory where the file exists using ‘cd’ command. Then perform following commands:

xvzf packagename.tar.gz
cd packagename
./configure
make
make install

That’s it. The program should be installed now.
