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. > Instead of reading the boot-up script, is there any > command to examine the "package application > configuration" as well as "system configuration"? 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. - : send the line "unsubscribe linux-admin" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
