I want to delete a user account. But I can't find any command to do so.
Is there any utility to do so?

Many of the Linux distributions ship with a deluser or userdel command that reverses the action of the adduser or useradd command. Search the man pages or simply try the commands to see if they exist on your system.
Failing that, deleting a user consists of two main steps:
1) Delete the user's entry in /etc/passwd
As root, and using your favorite editor, edit /etc/passwd (I always make a backup copy before messing with the password file because you can never be too careful). Search for the line that starts with the users login ID and delete the entire line.
2) Delete the user's home directory.
Again as root, use the rm command recursively to get rid of
files by typing

I have just added four additional drives to my Linux/Compaq
Proliant 1000. I recompiled the kernel to include the md/linear option.
Now I cannot find any instructions on how to make the MD work with
all the drives. What I want to do is have all five drives connected
such that when the first drive is full, the data will go to the
second drive and so on.

More information on using MD can be found in the MD FAQ at ftp://sweet-smoke.ufr-info-p7.ibp.fr/pub/linux/. You should find two files. The first, md-FAQ, can answer many of your questions. The second, md035.tar.gz (this is the current version of MD at the time of this writing), contains the utilities you will need to manage your MD system, as well as more documentation.
Be aware the MD package is still under development. Certain parts of
the system (such as mirroring) are not yet considered stable. If you plan
to use MD, I recommend you join the mailing list by sending mail
to majordomo@vger.rutgers.edu with the message body ``subscribe
linux-raid''.

I need to create a captive account which restricts the user
to only FTP access of the system. I also need to restrict the
user to accessing only directories above a root directory
I specify. Can you please let me know how to implement this?

First add a guest group entry in the /etc/ftpaccess file. Specify which group of users will be treated as guests by typing guestgroup ftponly. Then create the ftponly entry in /etc/group by typing ftponly::22:. Next, create a user member of this group, with no shell, in /etc/passwd:
user1:the_passwd:22:22:Limited FTP user:/home/ftp/user1:/bin/trueDon't forget to create the /home/ftp/user1 directory. Last, add /bin/true in /etc/shells. Now check your work to make sure it works!
There are simple and complex ways to restrict user access to FTP only. There is a HOWTO that describes this in detail, as well as potential security problems you should be aware of.
This FAQ is unfortunately not an official part of the Linux HOWTO and
mini-HOWTO compilation, but Slackware users can find it as part of the
installation anyway, in /usr/doc/faq/howto/mini/Anon-FTP-FAQ. Although the
document is geared primarily towards creating a secure anonymous FTP site,
it actually covers an extensive range of the setup required for your desired
effect.

After a successful installation of Red Hat's Colgate release of
Linux, I have found I would like to change some of my configuration
settings. Is there a way to get back into the setup utility that steps you
through setup? Or is there an easier way of doing this? In particular,
my NIC is not working right and I don't know how to configure it
correctly.

You need to use the control panel. It is an X-based set
of utilities. The control panel will start automatically if you do
a startx as root, or you can do a su, set your
DISPLAY environment variable, and then run control-panel. In particular you want to run the Network
Configurator (netcfg) and possibly the Kernel Configurator

Any Linux distribution should come with a bootpd (probably either
/usr/sbin/bootpd or /usr/sbin/in.bootpd) and a man page for it.
