NIS and User Port PermissionsSECURE CO NSO LE S ERVERS

7.9.4 User Names and Groups

The LSI Port User Definition file (/nis/lsi_port_users) is used to assign a

user to a given Port Access group. This file information is found in /usr/doc/nis.

The following example will illustrate how it is set up.

user name : group name

where

user name a valid SCS user

group name a valid user’s group

Example:

tomv : pbxgrp

billf : itgrp

The above example shows two users, tomv and billf. User tomv is in the group

pbxgrp and billf is in the group itgrp. When user with the lsi_port_access file, it illus-

trates how tomv can log into tvscs320 and be able to connect, monitor and clear the

ports that were set up in the previous example. The same goes for billf.

# LSI Port Access User definition file...

# Port Access user and their respective ‘port access group name is defined

# below.

# Users must be valid system usernames.

# Group names are those defined in the “lsi_port_access” file.

# user_name : group_name

lsiuser1 : user_group1

lsiuser2 : user_group1

lsiuser3 : user_group2

lsiuser4 : user_group2

Group Permissions

A user may not get access to a port, depending on their group permissions. Only

members of the scsusers group (group id of 701) may access SCS ports. Only members

of the monitor group (group id of 702) may access SCS monitor ports.

7.9.5 NIS Database file

The lsi_port_awk file is used to create the lsi database file (lsiportdbase)

on the NIS server. It contains the awk code that the Make file needs.
