Xen is a cuil package add-on for virtualization of the RHEL kernel. I understand it was not meant to fully operate at the level that VMware can but like in 300 with the supporting villager troops with the Spartans “they do thier part” …

When examining a 0-day exploit you compare:
system directory vs. user home directory vs. root compromise
everything is denied by default.
Mandatory Access Control (MAC)
The SELinux Linux Security Model (LSM) is incorporated in RHEL Core 5 andTrusted X Windows rocks on servicing MAC (as opposed to discretionary access control) with Flask security architecture which essentially breaks down the power of root.
Domain Name System (DNS) resolver
Red Hat Linux 7.1 also delivers new configuration tools that enable users to effortlessly set up and administer DNS
Establishing an Ethernet Connection
Managing DNS Settings
For Linux and Windows clients you may have a couple of options for your resolver configuration depending on your network environment:
suggested breakdown of your partitions ::based on a computer with 1GB of RAM and a 160GB hard drive/boot 100MB / 10240MB swap 2048MB (this should be twice and a half the size of your system memory) /tmp 5120MB /var 133120MB (this is where the majority of your web content will be stored) /var/log 10240MB
sd*
the way linux asign names to disk drive is as follows:
SD- SCSI or SATA based is designated as SD.
if it is denoted as HD- it denotes that the disk drive is IDE based.
When configuring formatting for Red Hat RHEL5 (Tikanga :: “the Māori right way of doing things”) working on setting partitions and primaries on SCSI or SATA or USB drives will be designated “sda”, “sdb”, “sdc” and so on.
x- denotes the position of the drive. If its installed in the IDE controllers as the Primary Master it will be designated as HDA. If as the Primary Slave it will be designated as HDB. If as the Secondary Master, HDC. HDD if the drive is installed as the Secondary Slave.
n- this denotes the partition number. For example the first partition of the Primary Master will be designated as HDA1. Usually the primary partitions are designated with the numbers 1-4. The logical drives are given the numbers 5-n (depends on how many logical partitions you have.
so you could have :
sda
sdb
sdc
sdd
etc…
RedHat Enterprise Setup Linux 5 steps while in VMWare:
Go to VMWare Infrastructure Client and select your Virtual Machine.
Power the VirtualImage On
Next goto Settings
and [X] checkbox set reboot to boot into BIOS
IN BIOS, go into [Boot Options Tab] and Set boot to CD Primary
While you are in there, Connect to CD/DVD ISO Image…
Browse to your RHEL ISOs
and then Exit out of BIOS and reboot thus launching the ISO
Cntrl+Alt to escape out of VMWare to your Desktop
then click
select language (duh) then click
select keyboard (yawn) then clickchoose to enter your install number
if you enter your Installation Number , you should have access to install add-on packages available with RedHat, otherwise you would probably be limited to only the essentials…
suggested breakdown of your partitions ::based on a computer with 4GBs RAM and 30GB hard drive
However, there are circumstances when you may want to restrict the growth of certain file systems. For example, if your mail spool was in the same partition as your root file system and it filled the remaining space in the partition, your computer would basically hang. first A primary partition should be planned. This partition ought to be a primary partition, not a logical partition at the front first 1024 MBs of the disk. This will ease recovery in case of disaster, but it is not technically necessary/var estimate to be 133120MB
(this is where the majority of your web content will be stored)
This file system contains spool directories such as those for mail and printing. In addition, it contains the error log directory. If your machine is a server and develops a chronic error, those msgs can fill the partition. Server computers ought to have /var in a different partition than /.
/var/log 10240MB/usr
This is where most executable binaries go. In addition, the kernel source tree goes here, and much documentation./tmp estimated size 5120MB
Some programs write temporary data files here. Usually, they are quite small. However, if you run computationally intensive jobs, like science or engineering applications, hundreds of megabytes could be required for brief periods of time. In this case, keep /tmp in a different partition than /./home
This is where users home directories go. If you do not impose quotas on your users, this ought to be in its own partition./boot 100MB estimated to be 10240MB
This is where your kernel images go. See discussion above for placement on old systems.
swap 2048MB for one or more primary logical swap partitions
(this should be twice and a half the size of your system memory)
For any other drive
One or more primary/logical partition(s)
Zero or more swap partition(s)…
Proceed in installing the core OS then you can use packet manager to custom install other software like Software Development IDE and Web Server wares…
