Resolving The Problem

This document explains how to administrate port restrictions using System i Navigator GUI interface.

Those with installed and working System i Navigator on their Windows PC can take advantage of full GUI implementation of port restrictions. Restrictions can be applied by either a single IP or a set range of IPs associated with a user or group name.


Step 1. Log in to your System i Navigator:



Step 2. Select [NETWORK >> TCP/IP Configuration] and right click on Properties:





Step 3. Select the Port Restrictions tab:



Step 4. Select Add and supply the correct field of information:





Important Note: A user profile that is used as a group profile may be specified in the user profile field of this command. If users have a group profile specified in their user profile and that group profile was specified for a particular port or range of ports, these users are given access to the specified port or range of ports. However, adopted authorities are not used when deciding whether this port is restricted or not. Each user profile or group profile that wants to use a port or range of ports must be explicitly added.

Example

There are two user profiles, USER_1 and USER_2. USER_2 is specified as a member of a group associated with USER_1. If the TCP port 1015 has a user profile list consisting of USER_1, a bind() by USER_2 will work because USER_2 is a part of the group profile USER_1.

Step 5. Click OK and Add more or Remove existing entries.
