Set user <user name> Idle_timeout <idle timeout value>

IMPORTANT: Please be aware that if you do not change the idle timeout

default value, which is set at 0, on-demand configurations will not

timeout. This means that you could incur costly telco charges. Therefore,

we recommend that you change this default from the CLI.

Before loading the RAS 1500 NT NOS Authentication application, be sure

to uninstall any previous versions of this or the AccessBuilder NOS

Authentication application that may have been used previously.

Use the following steps to install and configure NOS authentication

software on the Windows NT station:

1 Insert the RAS 1500 Resource CD into the Windows NT station.

2 Select Install Software from the Main Menu.

3 Select NT NOS Security. The setup program will be executed.

4 From the Windows NT desktop, click Start, then Programs, then RAS

1500 Security Client, then Enable Authentication.

5 Follow the directions to enable the service on the NT platform. This

ensures the service starts each time the machine is rebooted.

6 By default the NOS program is installed to authenticate users without

regard to time differences between the RAS 1500 and the NT system

running NT Security Client. If you do wish to use the NT Security Client to

check timestamps between the RAS 1500 and the NT system, change the

default time of 0 to 15 minutes.

7 On the NT system, go to Start, Programs, RAS 1500 Security Client and

select Security Client Config. The encryption key is a password exchanged

between the NT system and the RAS 1500. 3Com recommends you do

not change this. If you do, you must change the secret password on the

RAS 1500 the Web Configurator or the CLI with the following command:

set authentication secondary_secret [password]

8 By default, there is no timestamp checking (0). To check timestamps

between the RAS 1500 and the server, enter the allowable time

difference, for example, 15.

9 It is very important to set the date, time, and time zone correctly on the

RAS 1500 when using the timestamp check feature of NT Security Client.

To do this, through the Web Configurator click Date & Time/Timezone
