A month ago we published the world's exclusive review of Red Hat 8.0, Download Edition. In the meatime Red Hat, Inc. sent us a box of their newest product, Red Hat Professional. While the OS is pretty much the same as in the download edition and we have already made an extensive article on it, a few additional goodies await the customer in the box and we review them.

Here is the readme on that mini-CD. And apparently, it is free to download. One more reason to NOT buy Pro edition. Just get the Personal Edition if you want to support Red Hat.
Welcome to the Red Hat SysAdmin Survival CD Version 8.0.
=======================================================
This CD can be used to
- repair broken Linux systems
- help support tracing problems
- check if your hardware is supported by the latest Red Hat Linux release
This CD is based on Red Hat Linux 7.3. Some adjustments have been made to reduce the size of several applications.
Please send bug reports and other feedback to [email].
ftp://ftp.redhat.de/pub/rh-addons/rescue-cd/ contains the current version.
[So, you can download it off the web as well.]
Sample tasks this CD can be used for:
=====================================
Recovering your harddrive's filesystems
---------------------------------------
[Instructions here]
Some tools to repair your filesystems:
--------------------------------------
- fsck
checks your filesystems for errors and can repair damage
- gpart
guesses broken partition tables
- rescuept
rescuept <device> helps to recover the partition table
- badblocks
badblocks help you to detect bad blocks on your IDE drives
- mt
tool for tapedrive handling
- tar
backup/restoring tool
- dump/restore
backup/restoring tool
- sync
flushes filesystem buffers
Checking the network:
---------------------
The loader of our rescue cd tries to configure the network automatically. There are many possibilities to use this CD to check your network. Some tools which can be used to perform network tasks:
- dnsquery
performs dns queries to a nameserver
- host
echos data about the given hostname
- netstat
shows network connections from the local computer
- ssh
permits secure remote login
- scp
permits you to copy file from the local host to a remote computer securely
- ping
lets you check if a remote computer is reachable or not
(relies on the permission to send and receive ping packets in your LAN)
- telnet
lets you perform many checks and also permits you remote access
- ftp
lets you transfer files from the local to a remote host or vice versa
- ifconfig
lets you set/change the machine's IP address and configure additional
network devices
- traceroute
shows the route a TCP/IP packet takes to a specific host.
Help support tracing your problem
---------------------------------
A simple mailer is included on the Sysadmin Survival CD.
Usage example:
export MAILSERVER=mail.domain.org
export FROM=you@your.domain.org
export TO=yoursupportcontact@redhat.com
mail -s "Problem description" -e vi
You can now edit a message to your support contact. Maybe support will ask
you to attach some files - you can simply proceed:
mail -s "Corrupted password file" -f /mnt/rootfs/etc/passwd
Boot the Sysadmin survival CD and type "mail --help" for more information.
