Hi people :
I thought i should ask more than one question in a thread to save space on this forum and since i believe my questions are really simple ones too, hope you understand.

1.There is a linux server course (32 hours)that costs about US$150 and it enables you to become a linux network administrator(don't know if this is the correct translation , please correct me if i'm wrong since portuguese terms and english often look alike but the meaning is totally different), to know the main admin tools and to be abble to install and configure a network.What i wanted to know is if you think this is worthwhile doing ( i mean 32hours seems very little and also very cheap compared with nasty US$1300 i saw somewhere ), would you recommend a book instead ?
It was supposed to start last week but i was told no one signed in for it. They also told me that i had to have their first course first ,if i had no linux experience, which was basically :
-introduction
-instalation
-basic commands
-some notions on KDE and Staroffice

so i figured that with some effort i could learn more about the subject (which i imagine one could not fully understand on such small amount of lessons, i'm not that stupid).
BTW sorry if i posted here but another thing i would like to ask is about Slackware and other distros ( here in Brazil Linux is almost synonymimous of the connectiva linux distro):
How different would distros be from a server point of view ?

2. i realized that the netscape 4.77 version has everything that the version 6.0 has and more (it comes with the plugins i had to install on the later version afterall )so i decided to stick with the old one , but there's this small problem, i can't scroll text on it . Is there any simple way to do this ?

and lastly

3. I'm using Slackware as root all the time now. I knew that it might be dangerous as i could mess up something and it would not prevent me from doing so .But i started to have just one account ,at least,for the time being, as i configured everything i wanted (so i think ) and i noticed it would be much easier and quicker to work as root , well i read that you should not work only as root for it might be insecure :

can you tell me more about ? please , cause i'm really thinking of keeping root as my main account but i don't want to have hacking kind of trouble either (i need to get a firewall soon too but i still need to know what information do i need to set up one). Thanks a lot .

2: Not true - while it might have all the plugins that NS 6 has, its JavaScript support is more limited, and its CSS support is worse then pathethic.

3: Root can do anything on a system, and programs that are run by root can do anything on a system. If you run a program that has a bug / security hole / virus / anything else that isn't very nice then the worst it can do is trash your data files (which are easy to restore from backup) HOWEVER if you are running as root the worst it can do isn't as easy to recover from, it could trash your entire system and make it very easy to 3rd parties to use your machine as a springboard for attacks against other computers.

1: Be careful. Some courses just cram stuff up your STDIN , and that definitely doesn't make you a sysadmin automatically. Most "sysadmins" from those courses are security holes themselves. There is absolutely no substitute for experience and especially research you conduct yourself, that's the best kind of learning! I would definitely recommend a book (there should even be some free ones at http://www.tldp.org/) when it comes to basics. Don't bother wasting your time and money on their basics course.

thanks a lot . I have just donwloaded some stuff really interesting and i can't wait to get some more . I guess you were right sewer_monkey i better read and experiment .
