Appendix I: Frequently Asked Questions, and Resources

A Few Frequently Asked Questions

Question: How do I see my IP address?

For Windows95/98, go to Start menu, then Run, then type: winipcfg /all 
or for NT, go to Start menu, then Run, then type: ipconfig /all
This will show your IP number plus a lot more information.
(Seeing the same IP number more than once does not indicate if it 
is fixed or dynamically assigned. Ask your ISP for more information.)

For Macintosh, go to the Apple menu, then Control Panels, then
to the TCP/IP control panel.

Another method of finding out your IP number: 
Gibson Research's http://www.grc.com/ Shields Up! bypasses any proxy 
server and returns your computer's actual IP number.

Question: How can I see shared resources on my home PC?

In Windows98, go to Start, then Run, and type: \\xxx.xxx.xxx.xxx 
(where xxx.xxx.xxx.xxx is your home computer's IP number). The 
shared resoureces at that location will be shown. You can also 
type this in an Internet Explorer window.

Question: How do I limit access to my shared resources?

"Network Neighborhood allows you to treat the rest of the computers on 
the network and their shared resources as if they were inside of the 
Network Neighborhood folder." (need to find reference)

Windows95/98, NT, and Macintosh operating systems offer two levels of
access control: resource-level and user-level passwords. Resource-level
allows you to set a password on a specific folder or device. User-level
allows you to set a password for a user who can have access to many
folders and devices.

For more information on networking with Windows95, see the
clear, step-by-step section called "Letting Others Access Your 
Computer" from Intel(R) InBusiness[tm] products: Networking with 
Windows* 95

Another good page for disabling file/print sharing on Windows95/98
or Macintosh computers:  http://www.home.com/statement.html

Question: How do I set a password on my printer? I'm using Windows9x.

You can and should set passwords on shared printers and other
devices. For a printer, go to your Control Panels then open the
Printers folder. Right-click on the printer you wish to share, then
select Properties. Go to the Sharing tab and enter a password where
indicated. Click OK. Confirm your password if prompted.

Question: Where can I find more information on how to use
encryption?

While this site's graphics make it rather difficult to read,
the primer is good: http://ils.unc.edu/pgp/index.htm
