There are more than a couple of ways of updating Red Hat Enterprise Linux (RHEL) packages on your machine. One is by using up2date, the default package updater of RHEL systems. Unlike Fedora and CentOS which uses yum, up2date requires you to be registered to Red Hat Network (RHN) to be able to download or update your packages from the RHN repository.
Now, what if you need to install a certain package that is not available in your current repository by up2date? Or what if the package in the repository wreaks havoc in your system? Maybe you should try using yum to install or update rpm packages.
But… but… but how can I install yum in my RHEL machine?, you may ask. It’s actually very simple.
I got this tip from Babar Haq’s Blog with a little modification since I am using RHEL 4.
1. Download yum by using wget
# wget http://linux.duke.edu/projects/yum/download/2.0/yum-2.0.8-1.noarch.rpm
2. Install the rpm
# rpm -ivh yum-2.0.8-1.noarch.rpm
3. Configure /etc/yum.conf to use compatible repository
[main]
cachedir=/var/cache/yum
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
distroverpkg=redhat-release
tolerant=1
exactarch=1
[base]
name=CentOS-$releasever - Base
baseurl=http://mirror.centos.org/centos/4/os/i386/
gpgcheck=1
[updates]
name=Red Hat Linux $releasever - Updates
baseurl=http://mirror.centos.org/centos/4/updates/i386/
gpgcheck=1
4. Download and install the CentOS GPG Key
# wget http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-4
# rpm –import RPM-GPG-KEY-CentOS-4
5. Test yum to see if it works (I tested by running full update on my machine)
# yum update
*Note: This will update ALL installed packages in your machine. If you do not want to do this, cancel the process or skip this step.
If you reach step 5 without encountering any errors, it means that yum is successfully updating your machine with the latest versions available in the repo. 
This worked perfectly fine for me. If you experienced any errors, post a message and I will try to help you out

When using VMware for virtualization, you might encounter an error related to your sound device:
Failed to open sound device /dev/dsp: Device or resource busy
If you see this error, this means the sound device in your host machine is currently in use and the VMware client is not able to access the device. Here is also a little bit of information from the vmware knowledge base:
Some other program is using the sound device. You must quit that program first. While every virtual machine on a host can be configured with a sound device, only one virtual machine at a time can actively use the device. If another virtual machine is currently using it, simply terminate the application inside it that is producing sound.
Another possible cause is that the Enlightenment Sound Daemon is running and using the sound device. VMware recommends you turn off the Enlightenment Sound Daemon.
Though I have not found a way to fix this yet, there is a workaround that might help if you want to use sounds in your virtual machine. You might want to kill all esd processes:
# killall esd
You might need to restart your VMware service for the changes to take effect. This method will get the sound device available for your guest OS.
I have tested this on my machine running Fedora 7on my host machine and VMware Server 1.04 with Windows XP as guest OS. Works like a charm.
