196 Chapter 2 Command Descriptions
Index numbers and changing default port numbers
An index number is assigned to each of these services. The index numbers
assigned can vary over time. If you want to change the network port
number for a service, enter a “set service” or “show service” command to
display the current index number assigned to all services. Locate the
service for which you want to change the network port number, and note
the index number for the service. Enter a “set service” command, specify
that index number for the “range” option, and the new network port number
for the “ipport” option.
For example, to change the network port number for the Telnet basic
service from its default port number, 23, you would enter the following “set
service” command:
#> set service
which displays the services defined in and their current network port
number assignments:
Service Configuration :

Note that the index number assigned to the Telnet basic service is 1. You
would then specify that index number for the “range” option, and the new
network port number for the “ipport” option:
#> set service range=1 ipport=100
