What is systeminfo.sh?

	systeminfo.sh is a system information gathering script
	for linux systems. It in non-intrusive and simply gathers
	information from linux commands that are already available.

	Distribute freely... Modify openly... Send me any updates
	or ideas.

	CYA STATEMENT: *** USE AT YOUR OWN RISK ***
	As is the script does not write over or near any system files,
	unless someone modifies it to do so. ALWAYS TEST THE SCRIPT 
	ON A NON-PRODUCTION SYSTEM.

	FUTURE INTENT: Install the systeminfo.sh
	script in /usr/local/bin on all servers. Run it nightly, and
	rsync the data to a central server that has a httpd running
	on it. Farther down the road would be to compare the static 
	config data and check against it daily to see if something 
	changes. If so, send out notification as such. 

What kinds of information does it gather?
	Host		Software Packages	Memory
	OS Info		Process Info		Kernel Mods
	Network Routes	Socket Ports		ulimites
	chkconfig	Hardware Devices	swap
	disks		DNS info		top
	processor	sysctl			dmesg
	Cron Jobs	Network Interfaces	AND MORE....

What is supported?
	Currently only Red Hat and Fedora Core Linux is supported.
	Only Disks with sd, hd, cciss, and ida as devices
	Only ext3 filesystems.
	(This is all I can test against for the moment)
	(The script can easily be adapted to support more)
	firefox for browsing. We don't do MS.

HOW DO I INSTALL IT?
	It is only a shell script that needs to run as root. It can be
	executed from anywhere. 

How do I make it work in my environment?
	Just set the DPATH variable to where you want the data files to go.
	it is best to set the path to one of these paths:
	/tmp/systeminfo    /var/tmp/systeminfo   /usr/local/systeminfo

HOW DO I RUN IT:
	systeminfo.sh [OPTION]

	Only one option is allowed at a time:
	-a : Collect info, generate web pages and tar file, then display to stdout.
	-d : Display to stdout as it collects the info.
	-h : Display this message.
	-t : Creates just a tar file of the web pages for centralizing.
	-w : Creates just the web pages and master info file.

	When ran with no options the script will output to stdout
	Data collection can takes about 40-90 seconds depending on the system.

What is generated?
	A master file is generated that contains all the information collected and
	a series of text files that are displayed from 2 html files.

	[HOSTNAME].txt	Master collection of all information in one place
	index.html 	The initial starting web page
	menu.html	Displays the menu of possible collected data
	general.txt	general host information
	chkconfig.txt	contains chkconfig info
	cron.txt	contains all the crontabs set up
	disks.txt	Disk and partition configuratons
	dmesg.txt	the system dmesg
	network.txt	All the network info
	proc.txt	Process tables and top
	sockets.txt	Socket port connections
	software.txt	software rpm packages
	system.txt	system configs

	systeminfo_[HOSTNAME].tar	A tar file of the above files.

Why is a tar file generated? 
	A tar file is generated so that a central admin web server can
	remotely login, get the tar file, and extract it locally so 
	the local web server can see it.
