Chapter 3 - Software Loading and Configuration
4. Build your user database by filling in the following fields for each user.
User Name
The User Name can have as many as 39 characters. All printable characters are permitted with
the restriction that no blanks are allowed in the user name. In dial-in and dial-out applications, the
user name is treated as a case insensitive string.
User Passwor d
The User Password can have as many as 7 characters. In places where the password is used as
a character string, it is treated as a case insensitive string. Elsewhere (PPPs CHAP), it is treated
as a case sensitive pattern.
Filter
The drop-down list enables you to select the unique filter entry that was defined in the ID field in
the Add/Edit Filters dialog box. This filter ID must be a unique alphanumeric identifier of up to 9
characters in length that identifies the remote user.
Call Back
You have to click this check box to enable the Call Back function. If the user is at a location where
he wants to be called at then he must be allowed to choose the specific location where he wants
to be called back at. To do this, the Call Back option must be enabled (activated) and the Call
Back Security Enabled option must NOT be enab led (activated). The remote user would then use
a standard PPP client or ASCII terminal dial-in.
To enable Call Back Security , the Call Back option must be checked (activated) and the following
three boxes/fields filled in.
• Call Back Security Enabled
This parameter is of use in dial-in applications where the user must always be called back at
a specific location. Enabling this parameter (Alt-S) results in having the administrator
assigning the call back parameters. Leave this function disabled if the user is to be allowed to
choose the call back number and the call back delay.
• Call Back Number
The Call Back Number is editable only if Call Back Security is enabled (checked). This is the
number where the user will be called back. The user cannot choose the location where he
wants to be called back.
Note: You can enter the Call Back Number with or without dashes, the modem will simply
ignore them.
• Call Back Delay
Call Back Delay is editable only if Call Back Security is enabled. This specifies the duration
(in seconds) after which the user will be called back at the administrator-assigned number.
Dial In Ports
The systems administrator can enable (highlight) WAN Ports 1, 2, and/or 3 to be made available
for dialing in to the RASFinder.
Dial Out Ports
The systems administrator can enable (highlight) WAN Ports 1, 2, and/or 3 to be made available
for dialing out from the RASFinder .
Click the Rights button to assign user permissions for the remote user.
MTASR3-200

Chapter 3 - Software Loading and Configuration
5. The User Permissions dialog bo x displays.
6. Build your user permissions by filling in the following fields for each remote user.
Auto Protocols
This group enables the systems administrator to assign unrestricted LAN/Intranet access or
limited protocol access. You have the follo wing three options.
• None
This option allows the user to have unrestricted access to the LAN/Intranet. This is the
default setting.
• Telnet
This option allows Telnet sessions between the designated server (defined by the Host IP
Address field) and the remote users. Telnet is an applications-level protocol commonly found
in IP-based networks that allow terminal emulation at a remote workstation. If you select
Telnet, you are required to enter an IP address in the Host IP Address field. This limits the
user to only specific functions on the network.
• RLogin
This option allows the RASFinder to be used as an RLogin client for connecting to an RLogin
Server (defined by the Host IP Address field). RLogin is an application protocol that provides
a terminal interface between Unix hosts using TCP/IP network protocol. Unlike Telnet, RLogin
assumes that the remote host is a Unix machine. If you select RLogin, you are required to
enter an IP address in the Host IP Address field. This limits the user to only specific functions
on the network.
Host IP Address

Protocols
The Protocols group enables you to limit the remote user to IP routing, IPX routing, or bridging
(Spanning Tree); or, a combination of any two or all three routing protocols. The default setting
enables all three protocols.
User Service Types
The User Service Types group enables you to set the permissions for the entry being configured.
The systems administrator can enable or disable the following options to customize the types of
services for a particular remote user. By default, all permissions are enabled. To deny
permissions to the entry being configured, click (check) the box to the left of the permission to
disable the feature.
• Outbound Permissions - grants the remote user dial-out rights.
• Inbound Permissions - grants the remote user dial-in rights.
• Framed Protocol Permissions - gr ants the remote user fr amed protocol rights (e.g.,
Framed Protocol – PPP). By enabling (checking) this option, the user becomes an
unrestricted user (i.e., both framed and unframed protocols are allowed).
• Telnet Permissions - grants the remote user Telnet file transfer rights.
• RLogin Permissions - grants the remote user RLogin server connection rights.
Time Limits
The Time Limits group enab les the systems administrator to impose time-related restrictions to
the entry being defined.
Note: The SNTP Client check box must be selected in the SNTP Setup dialog box and pointed
to a valid time protocol server in order to monitor Time Limits and Time of the Day Logins.
Time of the Day Logins
The User Permission grid enables the administrator to deny a remote user Internet access at
certain times during the week. This would be applicable when the administrator wants to bring a
system down for a particular reason and does not want users to access the Internet at that time.
By default, all time periods are color-filled with yellow indicating that the remote user has
permission to access the Internet all the time. To deny permission for certain periods of time,
click all applicable yello w boxes over the target time range to toggle them to red (Access
Denied).
