Few Questions on Linux Servers.

[kanata]

Hi everyone,
I have few questions regarding linux Servers.

1.On x86 Machines ( Pentium4 ), What is the maximum number of Services( sshd, ntpd,named ,samba, etc.) that can be installed.? Is there a rule of thumb to attain the best possible performence.?

2. Is there a systematic way to boot a remote Machine.?

3. Are there any problems of having two dhcp servers on the same network.?

4. What is the equivalent to Group Policy in lInux.?

5. Can Linux Commands such as ( mkdir, ls, cat ) changed so that they behave different.?

6. How can you deny a user to use Linux Commands such as (mkdir, rm etc).?

7.How can I monitor what files users erase.?

8. How are the systems accounts different from user accounts.?

1: there is none, as a services (daemons) can differ greatly. If you are not using 100% cpu, then your good, if you are, then you should probably scale down.

2: man shutdown
most of the time, `shutdown -r now` will work, but you can change this depending on your environment.

3: yes, if you dont configure them right, they can cause problems, but it is possible to have 2, I just dont know how.

4: if your talking about file permisions, there are group permisions on files. see `man chown` and `man chmod`

5: yes, see `man command` to see all the options.

6: you can, but i dont know how well enough to inform you.

7: dont know

8: system accounts can't be logged into (technicaly not acurate, but the true difference is slim, and is usualy defined by each admin )

Let me see if I can help you with these homework questions.

1. There are...

Hang on. Asking for help with your homework is agains the rules of this forum. May I suggest you go back to your course notes and read then?

Hi everyone ,

The questions that I posted are not for school. I am new to LINUX; I wanted to clarify the Operating Systems capabilities and what it can do best.
So please, can anyone answer the questions, No one has really answered them all.

thanks,

Well you can pick up answers to these questions using your favourite search engine. Why don't you try Linux, and we'll help out if you have any problems installing or configuring it?

It still looks like the kind of questions that someone would ask on a term paper.

And meton_magis has had a good stab at answering some of these questions; I think you're being unfair to the volunteers here by suggesting that no one has.

1.On x86 Machines ( Pentium4 ), What is the maximum number of Services( sshd, ntpd,named ,samba, etc.) that can be installed.? Is there a rule of thumb to attain the best possible performence.?
No. of Serivces using will be depend on the resources such as RAM and disk space no. of users etc., and Pentium 4 is considerably good machine to work with those services
2. Is there a systematic way to boot a remote Machine.?
Ofcourse in terms of warm booting, come to me with specific requirements i will give a script to do that.
3. Are there any problems of having two dhcp servers on the same network.?
No, you can happily use and at present i am also using in the same way.
4. What is the equivalent to Group Policy in lInux.?
LDAP you can use as a cross plat form solution and NIS/NIS+ is also a good option
5. Can Linux Commands such as ( mkdir, ls, cat ) changed so that they behave different.?
yes, you define a custom path to the users where you want to happen in this way and define alias in their respective profiles with your command options.
6. How can you deny a user to use Linux Commands such as (mkdir, rm etc).?
you can define sudoers or as per Ans 5.
7.How can I monitor what files users erase.?
best way is to use w or else provide an alias to rm to mv and store in a diff location hope you got the logic
8. How are the systems accounts different from user accounts.?
System accounts will not have login credentials and will be invoked any time by others.
