CentOS Linux

There are six different runlevels in Linux, there could be more than six, but for compatibility reasons six are the default.

I have used RedHat and Debian based Linux, more specifically Fedora and Ubuntu and Debian itself, I have noticed that there is a difference in the runlevels on this different Linux distributions.

Well but first let's define the runlevels:

Runlevels in Linux are seven and they are:

- 0 = halt
- 1 = single user
- 2 = CLI, multi-user, no net
- 3 = CLI, multi-user, networked
- 4 = open
- 5 = GUI, multi-user, networked
- 6 = reboot

I always prefer to use the package manager instead of compiling from sources, mmh maybe compiling is more creates more efficient programs, than using binaries, but in that case, we better use Gentoo or Sabayon, but if we are using Debian/Ubuntu, or Centos/Fedora, I still think is better to use binaries.

Hi,

This post is to look for volunteers to help me compile and install KDE4 on Centos 5, I worked on this by this time for three days (and one night :) ).. If there is any volunteer I can post in the forums the steps I take so far, and the error I got, so we can continue working together.

Thanks and let me know if you are interested in the comments.

Update: here are my notes about what I am doing, hope this may help anybody, read How to compile KDE4 on Centos

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.

Introduction

If you need to upgrade some packages from the CentOSPlus repository, and do not want to upgrade the whole packages from it, you can enable the priority plugin of CentOS.

What CentOS will do is to install from CentOS Plus only the packages that only exists in that repository, or upgrade the ones that you will allow to upgrade from it.

I am starting to work with Asterisk, so as a first thing I tried to install it from repositories both on Debian and CentOS.

Let's start with Debian.

Once you have installed Debian

Just enter as root:

apt-get install asterisk

Then configure your sip.conf and extensions.conf as minimum, then edit the file:

/etc/default/asterisk

and change the option to start asterisk at boot from "no" to "yes"

As I wanted to install Asterisk on a CentOS Server and I did not need all the stuff a Default Server installation comes with, I made this installation of a CentOS server, only with the basic packages, so I can later install only the packages I may need.

This also applies for an Apache, or xSQL installation, I made some shots of the packages selection screens so you can use them to install your CentOS base system.

First go through all the screens selecting your language, keyboard, time zone, etc. these are two of those screens.

You can access a remote file system securely using sshfs and fuse which is a command to mount a remote filesystem encrypted through ssh.

This way you will be able to access remote files as if they were on you machine, just remember that if the connection between the computers is slow, the access will also be pretty slow.

Ok, I have not tested this yet, as soon as I did I will update this posts, so please if you try it and have good results (or bad) post it on comments.

My friend from http://polishlinux.org, send me this links, that are a good complement to my post of choosing the Linux distro.

Hello, I will try today to share my little experience on using Linux, the
distribution if have tested are:

• Fedora
• CentOS
• Ubuntu
• Debian

CentOS 5.0 the Linux distro based on RedHat has been released, few weeks later RedHat itself has been released.
The news for this version of Centos are among others:

Once I have a problem with a CentOS server (Could be the same on RedHat based). The HOSTNAME given on the instalation was not the reverse lookup name.

I solved with the help of the linux list, here is how.

If you ever need to reinstall your Grub loader, here is how to.

As VNC is not a secure way to connect to your linux server, you can run VNC over an SSH connection, here is how

Hi,

If you want to make your linux machine balance the load of your internet access, you can use ip route.

QEMU, is a great alternative to VMWare or XEN, for installing let's say Windows on your Linux Machine

Whenever you need to left open the port 22 for ssh you machine from every where,but want to prevent Dictionary attacks, you can use DenyHosts to stay protected

First thing you need as DenyHost runs as a python script, is to be sure you python installed.
