System Boot-Up Configuration

Hey Friends,


I am new to RedHat Linux.

What is the best way to examine the system configurion
immediately after system-boot-up?


Instead of reading the boot-up script, is there any
command to examine the "package application
configuration" as well as "system configuration"?


Thank,
MIke

Not sure what you are after, exactly, but you will find a plethora of
info in the /var/log files and configurations are usually under
/etc/something (like /etc/httpd/conf for apache, /etc/squid, /etc/mail
....) and /etc/sysconfig holds a lot of stuff for system settings and
the list can go on all day.

It's very SysVish so if you are used to other Unices then that might
help. /etc/rc.d/init.d is where all your startup scripts live and
they are all called through their corrisponding links in the
/etc/rc.d/rc#.d (replace # with your run level, default is 5,
methinks). Startup scripts start with uppercase "S" Kill scripts with
uppercase "K". So, you can usually figure out what all is running and
how it is configured by sifting through these scripts.

Also "man man" and "man ps" are your friends today.

That would depend on the package, but I doubt it. You could simplify
things with webmin which is part of most RH default installs. Check
/etc/init.d/ for webmin and start it. The best way to know your OS is
to know it, get dirty with it, find out where things are and how to
tickle it.

Remember when asking questions in *NIX forums/lists/newsgroups to
include OS and product versions and be specific as possible in your
queries. NEVER top post and always trim out the junk (good habbit to
form for when you go to the hardcore lists)

Enjoy, and welcome to the wonderful, robust, world of Linux, where you
are in control of your OS, if you want to be. :)

Scott.
