We the Linux users, are always interacting with Windows users, and one of the most difficult part of that interaction is the exchange of documents, that they create and edit mostly with Microsoft Office, and we use Open Office, and I think that even if they use OpenOffice, they will have access to the system's fonts, so, we need MS fonts installed in our Linux Operating System, in order to look at the documents in the same way they are looking at it.

Let's go first with

Debian / Ubuntu

It is really easy, just enter at the console, the command:

sudo aptitude install msttcorefonts

And that is all.

Fedora / Centos

Here we will need a little more job

1. Install the software needed

sudo yum install rpm-build cabextract

2. Download the specs to build the RPM

wget http://corefonts.sourceforge.net/msttcorefonts-2.0-1.spec

3. Build the RPM

rpmbuild -ba msttcorefonts-2.0-1.spec

4. Install the RPM

rpm -ivh /usr/src/redhat/RPMS/noarch/msttcorefonts-2.0-1.noarch.rpm

Thats all, now you have installed your new fonts on your system, you can start using them immediately in you Open Office, or in any other application, I have tested on Fedora, Ubuntu, Debian with Gnome and KDE.
