For Comfortable Network Use, Free Software Is Required
Software selection must be suitable for specific purposes
- Free software is indispensable if networks are to be used with
comfort. The software can add functions that your PC’s operation
system does not have or it can enhance its standard features. In fact,
a number of free applications actually overshadow commercial software.
This article looks at 10 specific purposes and examines Windows-based
free software that can be used in each case. Nikkei Network helps you
to create a unique “tool box” for your own use by collecting
the necessary free software.
Purpose 1: To create an address list for a certain device that exists
in a LAN
Purpose 2: To check whether or not unnecessary ports are open
Purpose 3: To measure the speed of a line for throughput and downloads
Purpose 4: To find a program that communicates with other computers
on the Internet without the user knowing about it
Purpose 5: To create a secure password that is not easily compromised
by a hacker
Purpose 6: To check the country from which an unauthorized packet was
transmitted
Purpose 7: To transmit a processed packet for testing
Purpose 8: To create a dummy server for checking protocol processing
Purpose 9: To exchange huge files easily
Purpose 10: To let your PC perform troublesome subnet calculations
All-Purpose Tools: To create the most useful “tool box”

Results of Nikkei Network’s Questionnaire Survey of 1800
Network Users
Frequent troubles in networks today
- Unfortunately, we cannot simply side step trouble when we operate
or use networks. It can be said that all network users have experienced
some kind of trouble. In order to come up with ways to deal with future
trouble, this article examines how the problems were resolved in those
cases covered in the questionnaire survey.
Part 1: There is a problem with a device or a cable
- Every device breaks down at some point, and when a layperson constructs
a network, he or she should be very careful
Part 2: There is a problem with the environment where network devices
are installed
- Noise is the worst enemy of communication, and potential causes of
noise exist in wiring
Part 3: There is a problem with configuration
- Despite the appearance that a network is working normally, there
can still be an error in the network that causes problems
Summary: Many problems occur due to typical causes
