Free red hat certification software for linux

Red Hat Linux is probably the best-known Linux distribution. Red Hat Linux is well-supported by commercial software, and tends to be easy to install and have good hardware support out of the box.

Compaq has taken over the maintenance for Red Hat for their Alpha processor - theres a link to their Alpha Red Hat page below.

Red Hat 9 is the last version of Red Hat Linux per se, and Red Hat will stop supporting it soon. Instead they offer a commercial Linux distribution, "Red Hat Enterprise Edition", and a free distribution, "The Fedora Project".

Scientific Linux is a Linux release put together by various labs and universities around the world. Scientific Linuxs primary purpose is to reduce duplicated effort of the labs, and to have a common install base for the various experimentors.
The base Scientific Linux distribution is basically Enterprise Linux, recompiled from source.
Our main goal for the base distribution is to have everything compatible with Enterprise, with only a few minor additions or changes. An example of of items that were added are Pine, and OpenAFS.
Enhancements:
- Scientific Linux 5.0 i386 is now available." Some of the extra applications include: "CFITSIO - a library of C and FORTRAN subroutines for reading and writing data files in FITS; FUSE - an implementation of a fully functional file system in a userspace program; Graphviz - graph visualization tools; IceWM - a lightweight window manager; Intel wireless firmware, MadWiFi and NdisWrapper; Java; MP3 support; OpenAFS; R - a language and environment for statistical computing and graphics....

Using
To use Red-Piranha - open your favourite web browser and point it at http://localhost:8080/RP . Within a few seconds , you should see the Red-Piranha start screen. This will have three items of interest
- A Text box , where we enter the information to add or search
- An add information button - to tell Red-Piranha about new information
- A Search button - to carry out a search.
Before we can search , we must tell Red-Piranha we information we are interested in. This is as easy as putting the piece of information we want to add (e.g. the folder c:temp) in the search box and pressing the Add information button. A message will be displayed saying that your information is being added and will be available to search shortly. For more information , look in the logs at TOMCAT_HOMEWebappsRPlogsrp.log
Examples of things we can add to Red-Piranha are
- A folder (e.g. C:Temp). All files in both this folder and *all* its subfolders will be added.
- An individual file. This file can be text , a web page , a word document , or pdf document. For binary files (like word , which are not plain text) , Red-Piranha will scan the file for recognizable text and add that.
- A Web page. Red-Piranha will add this web page , *and* web pages it links to.
- A Google Search (e.g. http://www.google.com/search?q=some+thing?m=100). Red-Piranha will get the results of the google search , and add information on the pages it links to.
- An XML file (including RSS feeds) , either on disk or over the web.
- Favourites / Bookmarks folders - Red-Piranha will index the web pages that these favourites point to.
Adding information can take anything from a few milliseconds , depending on the amount of information being added. Once added, Red-Piranha will check on a regular basis to see if the information added has changed and re-index if required. Your information is now available to be searched.
To do a search , put the item you want to search for into the textbox and press search. Red-Piranha will show the search results on the screen. Clicking on the link beside the search results will show you the original information (as long as you have access to it).
From version 0.3 onwards , Red-Piranha can learn what search results you are interested in an improve your future searches. To give Red-Piranha feedback and help it learn what you are interested in , click on any of the links on the search results page. Red-Piranha makes a note of your choice , which is used to adjust the search results later.

Lineox Enterprise Linux distribution is based on source RPM packages from which Red Hat Enterprise Linux is compiled. Lineox Enterprise Linux contains all programs included in various Red Hat Enterprise Linux variations (Advanced Server (AS), Entry/Mid Server (ES), and Workstation (WS)).
It also contains programs included in separately sold Red Hat Cluster Suite and Red Hat Developer Suite. Lineox has removed and replaced all files of Red Hat Enterprise Linux which have restrictive copyright by Red Hat, Inc. Lineox has also tried to remove all user-visible references to Red Hat in Lineox Enterprise Linux.
The most notable difference between Lineox Enterprise Linux and Red Hat Enterprise Linux is the support options provided by Red Hat, Inc. Lineox, Inc. does not provide any support for Lineox Enterprise Linux with the base product.
Lineox, Inc. however plans to provide binary package updates for Lineox Enterprise Linux as long as Red Hat, Inc. provides updates for Red Hat Enterprise Linux in source package format.
Lineox has an automated system running on a cluster which builds new binary rpm packages as soon as new source code is available. New rpm packages are usually available in less than 12 hours after source code release.
After that Lineox builds Always Current Lineox Enterprise Linux disks automatically, but because of the time it takes to transfer the disk images to our web server, they are available from 2 to 12 hours after we release new packages.
Isnt Always Current Lineox Enterprise Linux untested or unreliable if it is released so often? Not really. We dont rebuild the installation environment, we just replace the installable packages with new ones.
You can even use same boot floppies or other boot media created for Lineox Enterprise Linux 4.0 to boot Always Current series Lineox Enterprise Linux. So Always Current Lineox Enterprise Linux is as tested and reliable as a system installed from "base release" and updated later. The only difference really is the work and time saved and the higher security right from the start.
Enhancements:
- Always Current Lineox Enterprise Linux 4.096 with Update 4 available. In the version 4.096 the installation environment is rebuilt, so it offers better hardware support during the installation. See the release notes for full information. The x86_64 release requires either AMD Opteron or Athlon64 CPU based computer. Some new Intel Xeon and Pentium IV processors with EM64T (Extended Memory 64 Technology) will also be able to run this version.

Linux NFS Utilities are NFS utilities for Linux NFS clients and servers.
Main features:
- NFS Versions 2, 3, and 4 are supported on 2.6 and later kernels.
- NFS over UDP and TCP on IPv4 are supported on the latest 2.4 and 2.6 kernels.
- Linux NFS clients and servers have been tested against many non-Linux implementations.
- Since version 1.0.1 of the NFS utilities tarball has changed the server export default to "sync", then, if no behavior is specified in the export list (thus assuming the default behavior), a warning will be generated at export time.
- If you plan to deploy NFS extensively, consider subscribing to one of these mailing lists: NFS Mailing List, or the AutoFS Mailing List. Before reporting problems, you should search for similar issues in the searchable mail archive. Another searchable archive for NFS, supported by Google, is here. The searchable mail archive for AutoFS is here.
- A useful set of generic NFS references includes the following:
- - "NFS Illustrated," by Brent Callaghan; Addison-Wesley, 2000.
- - "Managing NFS and NIS, 2nd edition," by Hal Stern, Mike Eisler, Ricardo Labiaga; OReilly, 2001.
- - "Linux NFS and Automounter Administration," by Erez Zadok; Sybex, 2001.
- - "Using the Linux NFS Client with Network Appliance Filers," by Charles Lever; Netapp TR-3183, 2004.
- - "Mike Eislers NFS blog."
- - "Eric Kustarzs blog."
- - "NFS version 4 home page."
- - Finally, the "linux.org online library" has many references.
Quick setup client guide
1. Acquire and install a recent distribution of Linux.
2. Set up your /etc/exports file (man exports for details).
3. Consult your distributions documentation to determine which /etc/init.d start-up script is used to start your server. Start NFS services by invoking this script as root, using the "start" parameter. Consider adding this script to the list of scripts that are automatically run at system start-up. (Red Hat uses the chkconfig command for this purpose).
4. Read the NFS How-To for advice on tuning and securing your server.
Quick Client Setup Guide
1. Acquire and install a recent distribution of Linux. To enable NLM lock recovery, ensure your clients host name, as returned by uname -n, matches the host name returned by DNS.
2. The NLM protocol is handled by an in-kernel service in modern kernels, but the user-level rpc.statd program must be running to enable NLM lock recovery. Consult your distributions documentation to determine which /etc/init.d start-up script is used to start it. Start the NSM daemon by invoking this script as root, using the "start" parameter. Consider adding this script to the list of scripts that are automatically run at system start-up. (Red Hat uses the chkconfig command for this purpose).
3. Create the directories on your client where you will mount the NFS shares.
4. Add entries in /etc/fstab corresponding to your mount points (man nfs for details).
5. Use mount -a -t nfs to mount the NFS shares.
6. During system boot-up, most distributions automatically mount NFS shares that are listed in /etc/fstab. If yours doesnt, check your distributions documentation for instructions on how to configure your client to do this.
Enhancements:
- The "mount.nfs" command was added, since the nfs mount functionality is being migrated from util-linux to nfs-utils.
- Substantial changes to were made statd. Various pieces of old code were removed.
- Lots of bugfixes and improvements were made.

The PHP Firewall Generator is a simple PHP script that generates a firewall script for iptables or ipchains based firewalls. The script is created based on configuration rules entered by the user. The aim is to support a rule set similar to those supported by commercial Firewall systems, and make it easy to configure.

Make sure that you have apache and PHP installed (tested with apache-1.3.19-5 and php-4.0.4 from Red Hat 7.1 but shouldwork with others).

Make sure that PHP is actually running.
Make sure that you have iptables installed. Tested with iptables-1.2.1a-1 from Red Hat 7.1
Run this as root:
make install
If you dont have make installed on your system, then you could just run:
installme
Make sure that the files in /var/www/html/phpfwgen/ are readable by the HTTP daemon user (often httpd or apache) and that the files in /var/lib/phpfwgen are readable AND writeable by this user.
The script gets copied into /var/www/html/phpfwgen/ so you should be able to access it as http:// /phpfwgen/
Make sure that the files created in /var/lib/phpfwgen make sense, particularly the "interfaces" file.
