What are the .plan and .project files read by the
finger command and what should they contain?

In the good old days before the Web, there were no home pages. Instead, if I wanted to find out more about someone, I would ``finger'' them. The finger command asks the server to display information about a user, including the contents of the user's .plan and .project files. You can put any information you wish in these files: your name, e-mail address, fax and phone numbers or favorite sayings.
Note that many system administrators consider the
finger command to be a potential security risk and have turned it off, so don't
be surprised if you ``finger'' someone and receive a message along the lines of
``access denied''. Also, many implementations of finger read only the
.plan file.

I have a PC with an Intel Pentium 150. Will Linux run on it?
I've heard it runs on a 386 or a 486 but has trouble
with certain IBMs--I'm not sure which ones.

You should have no problem running Linux on the machine you
describe. Early versions of the Linux kernel were unable to support true IBM
machines that used the microchannel architecture or MCA (the PS\2 line). That's probably the
IBM computer referred to.

Most likely you need to find the hdparm package and
use it to set the spin down times. I know it can do this for
IDE drives. If it's not part of your distribution, you can find it on
Sunsite.

Are there any drivers that provide SCSI support on the motherboard?

That depends on the type of SCSI you wish to use. You can
check the hardware compatibility lists at http://www.redhat.com/.

After installing Linux, I noticed I am missing an option
available
in MS Windows: the US-International keyboard layout. This layout lets anyone
with a US keyboard type the special punctuation needed for foreign
languages. I live in Puerto Rico, and most, if not all, keyboards sold here
are US versions. Since I write mostly in Spanish, I am interested in
learning how to make a keymap that emulates Windows' US-International
layout. Is there any information about the subject or any already-made
keymap file that fits the job?

There may indeed be a keyboard mapping that fits your keyboard. If not, you will have to take one that is close to your desired arrangement and modify it.
You should obtain the kbd package from
ftp://sunsite.unc.edu/pub/Linux/system/keyboards/kbd-0.98.tar.gz. It
contains tools, documentation and examples that will assist you in your
remapping project. It also contains a file called kbd.FAQ, which contains
answers to
frequently asked questions about the operation of the keyboard under
Linux.

I have a problem with hackers and one security hole is the command
su.
I have several users on my system. While I don't want to eliminate the
capability of these users to change to other IDs, I do want to eliminate the
capability to use su to change to root for all except one or
two users. Is this possible?

You may be missing a handy program called sudo, which you can obtain from your nearest Sunsite mirror. This program allows you to configure su actions for each user based on who the user is and what you wish him to be able to access.
If that does not meet your goal, why not fall back to the standard Unix security functions? Create a new group called su. Change the group on /bin/su from bin to su. The permissions are most likely 4755 (-rwsr-xr-x), which means anybody can execute it and the program will execute as root.bin.
You can then change the permissions of /bin/su.
Try changing them to 4750 (-rwsr-x---), which allows root or any user in the su group
to execute it. Then you can put those users you wish to have
su privileges in the su group.

How do I use man? For example, when I enter:
man lsI get a blank screen with a weird message at the bottom of the screen--something like 1/1. Whatever I enter, it beeps at me.
Check whether there are any files in the /usr/man/manx directory
(where x is a number, usually from 1 to 8). You should find several different
files with names like gpm.1. Each of these files is a man page. Whenever you
use the man command, you get a processed version of
the file corresponding to the command specified (for the
ls command, it is the ls.x file).
For this file to be processed, the groff utility must be
installed. groff is usually found in the /usr/bin directory.

When I installed Linux, I didn't set up a swap space. I have since created a swap file but I have to enter:
swapon /dev/hda5every time I boot, and I can do it only as root. Can I make this simpler?
Slackware puts entries to automatically mount swap partitions (if they exist) in your rc script files. All you need to do is tell those files that your swap partition exists and is available for use. To do that, put a line in the /etc/fstab file like the following:
/dev/hda5 swap swap defaults 1 1This tells the system to set up a swap space from /dev/hda5 with the default settings for a swap partition. This entry is normally created by the setup scripts when you install Slackware, and is the missing item that prevents your swap area from being initialized with each boot.
