# This program is used to stress test the LANforge system, and may be used as
|
|
# an example for others who wish to automate LANforge tests.
|
|
|
|
# The purpose of this script is to create 10 (or more) TCP and/or UDP connections on
|
|
# specified ports. The connections will run for a short period of time, and
|
|
# then 10 more will be created on a new set of ports (the next 10). It
|
|
# writes it's cmds to a log file so you can get an idea of what it's doing.
|
|
#
|
|
# This script should be useful for people who are testing firewalls and other
|
|
# types of systems that care about what ports the data is transmitted on...
