1. Introduction

The RSM-8, RSM-16, RSM-16DC, RSM-32 and RSM-32DC Remote Site Managers provide in-band and out-of-band access to RS-232 console ports and maintenance ports on UNIX servers, routers and any other network element that includes a serial console port. System administrators can access the RSM via TCP/IP network, using SSH or Telnet, or out-of-band via modem or local terminal. The RSM features two separate command interfaces; a convenient, user-friendly web browser interface, and a simple, command driven text interface.

Intelligent Port Selection

Each of the RSM’s RS232 serial ports can be individually accessed by number, name or group via SSH or Telnet sessions. The RSM also allows direct connections using TCP port assignments. Each RSM serial port can be separately configured using simple menu driven commands to set the port password, data rate, flow control and other operating parameters.

The full matrix capability of the RSM allows you to easily connect any two ports on the switch, even when the ports are using different communications settings. Ports can also be connected or disconnected by a third party with supervisor rights, and system managers can swap various RS232 devices between ports at a remote location.

Security and Collocation Features

Secure Shell (SSHv2) encryption and address-specific IP security masks prevent unauthorized access to command and configuration functions. The RSM also provides two different levels of user security; the Supervisor level and the Non-Supervisor level. The Supervisor level, which is intended for use by system managers and other administrators, provides complete access to all RSM port connection / disconnection functions, operating features and configuration menus, and also allows access to any port on the switch. The Non-Supervisor level is ideal for collocation applications, since users are only permitted to view status and connect to the ports allowed by their password.

Capture Buffer

"Buffer Mode" allows individual ports to capture and store incoming data, such as error and status messages received from attached console ports. This "snapshot" of the last data received is stored in memory, and can be viewed, saved, or erased by the system operator at any time. Console messages can be stored in the RSM port buffers, and sent to a remote location via SYSLOG, or an SNMP message can be generated to alert administrators when new console messages are received.

1-1

Configuration Backup

Once you have configured the RSM to fit your application, parameters and options can be saved to an ASCII text file on your PC. This allows you to quickly restore userselected parameters if unit configuration is accidentally altered or deleted. Saved parameters can also be uploaded to other RSM units. This allows rapid set-up when several units will be configured with identical or similar parameters.

RSM-8, RSM-16, RSM-16DC, RSM-32 and RSM-32DC Units

This User’s Guide discusses five different models from our RSM product line: the RSM-8, RSM-16, RSM-16DC, RSM-32 and the RSM-32DC. Throughout this User's Guide, all of these units are referred to as the "RSM." Note however that these units differ as described below:

• RSM-8: 8 Serial Ports, 100 to 240 VAC, 50/60 Hz, 5 Watts

• RSM-16: 16 Serial Ports, 100 to 240 VAC, 50/60 Hz, 5 Watts

• RSM-16DC: 16 Serial Ports, -48 VDC

• RSM-32: 32 Serial Ports, 100 to 240 VAC, 50/60 Hz, 5 Watts

• RSM-32DC: 32 Serial Ports, -48 VDC.

Aside from the differences listed above, all other features function identically in all five models.

5. Configuration

5.1. Communicating with the RSM Unit

In order to configure the RSM, you must first connect to the unit, and access command mode. Note that, the RSM offers two separate configuration interfaces; the Web Browser Interface and the Text Interface.

In addition, the RSM also offers three different methods for accessing command mode; via network, via modem, or via local console. The Web Browser interface is only available via network, and the Text Interface is available via network (SSH or Telnet), modem or local PC.

5.1.1. The Text Interface

The Text Interface consists of a series of simple ASCII text menus, which allow you to set options and define parameters by entering the number for the desired option using your keyboard, and then typing in the value for that option.

Since the Web Browser Interface and Telnet accessibility are both disabled in the default state, you will need to use the Text Interface to contact the unit via Local PC or SSH connection when setting up the unit for the first time. After you have accessed command mode using the Text Interface, you can then enable Web Access and Telnet Access in order to allow future communication with the unit via Web Browser or Telnet. You will not be able to contact the unit via Web Browser or Telnet until you have specifically enabled those options.

Once Telnet Access is enabled, you will then be able to use the Text Interface to communicate with the RSM via local PC, Telnet or SSH connection. You can also use the text interface to access command mode via the RSM's internal modem, or via an external modem installed at one of the RSM's RS232 serial ports.

In order to use the Text Interface, your installation must include:

• Access via Network: The RSM must be connected to your TCP/IP Network, and your PC must include a communications program (such as HyperTerminal.)

• Access via Modem: A phone line must be connected to the RSM's Phone Line port, and your PC must include a communications program.

• Access via Local PC: Your PC must be physically connected to one of the RSM’s RS232 ports as described in Section 4.3, and your PC must include a communications program.

5-1

Configuration

To access command mode via the Text Interface, proceed as follows:

Note: Command mode cannot be accessed via a Buffer Mode Port, Passive Mode Port, or any port that is presently connected to another RSM port.

1. Contact the RSM Unit:

a) Via Local PC: Start your communications program and press [Enter]. Wait

for the connect message, then proceed to Step 2.

b) Via Network: The RSM includes a default IP address (192.168.168.168) and a

default subnet mask (255.255.255.0.) This allows you to contact the unit from any network node on the same subnet, without first assigning an IP Address to the unit. For more information, please refer to Section 5.8.

i. Via SSH Client: Start your SSH client, and enter the RSM’s IP Address.

Invoke the connect command, wait for the connect message, then proceed to Step 2.

ii. Via Telnet: Start your Telnet Client, and then Telnet to the RSM’s IP

Address. Wait for the connect message, then proceed to Step 2.

Note: When communicating with the unit for the first time, you will not be able to contact the unit via Telnet, until you have accessed command mode, via Local PC or SSH Client, and used the Network Parameters Menu (/N) to enable Telnet as described in Section 5.8.

c) Via Modem: Use your communications program to dial the number for the line

connected to the RSM’s Phone Line port.

2. Login / Password Prompt: A message will be displayed, which prompts you to enter a username (login name) and password. The default username is "super" (all lower case, no quotes), and the default password is also "super".

PORT STATUS: Site ID: (undeﬁned) 02/07/2007 00:23:39 GMT (GMT+0000)

Enter /H for command menu. RSM>

5-2

Configuration

3. If a valid username and password are entered, the RSM will display the Port Status Screen, shown in Figure 5.1.

Note: If the Telnet connection is refused, it is most likely due to one of the following reasons:

• The IP Security feature has denied the connection.

• You are attempting to use an account that permits Supervisor commands to

connect to a port that does not permit Supervisor Commands.

5.1.2. The Web Browser Interface

The Web Browser Interface consists of a series of web forms, which can be used to select configuration parameters and enable/disable RSM operating functions, by clicking on radio buttons and/or entering text into designated fields.

Notes:

• The Web Browser Interface cannot be used to connect and disconnect ports;

the Web Browser Interface is used only for configuration purposes.

• In order to use the Web Browser Interface, Web Access must be enabled

via the Text Interface Network Parameters Menu (/N), the RSM must be connected to a TCP/IP network, and your PC must be equipped with a JavaScript enabled web browser.

1. Start your JavaScript enabled Web Browser, key the RSM’s IP address (default =

192.168.168.168) into the web browser’s address bar, and press [Enter].

2. Username / Password Prompt: A message box will prompt you to enter your username and password. The default username is "super" (all lower case, no quotes), and the default password is also "super".

3. If a valid username and password are entered, the RSM Home Screen will appear as shown in Figure 5.2.

Configuration

5.2. System SetUp Ports

Serial Ports 1 and 2 are reserved as SetUp Ports, and will always permit password protected access to Supervisor commands. Therefore, Ports 1 and 2 cannot be configured as Buffer Mode Port or Passive Mode Ports, because these port modes do not permit access to command mode. In addition, the Supervisor Mode cannot be disabled at Ports 1 and 2.

5.3. Configuration Menus

Although the Web Browser Interface and Text Interface provide two separate means for selecting parameters, both interfaces allow access to the same set of basic parameters, and parameters selected via one interface will also be applied to the other. To access the configuration menus, proceed as follows:

• Text Interface: Refer to the Help Screen (/H) and then enter the appropriate command to access the desired menu. When the configuration menu appears, key in the number for the parameter you wish to define, and follow the instructions in the resulting submenu.

• Web Browser Interface: Click the appropriate button on the left hand side of the Home Screen (Figure 5.2) to access the desired configuration menu. To change parameters, click in the desired field and key in the new value or select a value from the pull-down menu. To apply newly selected parameters, click on the "Change Parameters" button at the bottom of the menu or the "Set" button next to the field.

The following sections describe options and parameters that can be accessed via each of the configuration menus. Please note that essentially the same set of parameters and options are available to both the Web Browser Interface and Text Interface.

Note: Configuration menus are only available when you have logged into command mode using a password and port that permit Supervisor Level commands.

Configuration

In the Text Interface, the System Parameters menu is also used to create and manage user accounts and passwords. Note however, that when you are communicating with the unit via the Web Browser Interface, accounts and passwords are managed and created via a separate menu that is accessed by clicking on the "Users" link on the left hand side of the menu.

• Text Interface: Type /F and press [Enter]. The System Parameters Menu will appear as shown in Figure 5.3.

• Web Browser Interface: Click the "System Properties" link on the left hand side of the RSM Home Screen. The System Parameters menu will be displayed as shown in Figure 5.4.

The System Parameters Menus are used to define the following:

• User Directory: This function is used to create, modify and delete user accounts and passwords. As discussed in Section 5.6, user accounts allow you to set the security level for each password as well as determine which ports a user will be allowed to access.

Note: The "User Directory" option does not appear in the Web Browser Interface’s System Parameters menu, and is instead, accessed via the "Users" link on the left hand side of each configuration menu.

• Site ID: A text field, generally used to note the installation site or name for the RSM unit. (Up to 32 chars.; Default = undefined.)

Notes:

• The Site ID cannot include double quotes.

• The Site ID will be cleared if the RSM is reset to default settings.

• Real Time Clock: This prompt provides access to the Real Time Clock menu, which is used to set the clock and calendar, and to enable and configure the NTP (Network Time Protocol) feature as described in Section 5.4.1.

• Invalid Access Lockout: If desired, this feature can be used to automatically disable an RSM serial port after a user specified number of unsuccessful login attempts are made. For more information, please refer to Section 5.4.2.

• Audit Log: Enables and configures the Audit Log feature, as described in Section 5.4.3. (Default = On - Without Syslog.)

• Callback Security: Enables / configures the Callback Security Function as described in Section 5.4.4. In order for this feature to function, a Callback number must also be defined for each desired user account as described in Section 5.6.

• "/PW" Command: Enables/Disables the /PW (Change Password) command. When enabled, the /PW command can be issued at the text interface by any user account in order to change that account’s password. When disabled, accounts that do not permit Supervisor commands will not be able to change passwords. (Default = Off.)

Configuration

5.4.1. The Real Time Clock and Calendar

The Real Time Clock menu is used to set the RSM's internal clock and calendar. To access the Real Time Clock Menu, proceed as follows:

• Text Interface: Type /F and press [Enter]. The System Parameters menu will appear as shown in Figure 5.3. At the System Parameters menu, type 3 and press [Enter] to display the Real Time Clock menu.

• Web Browser Interface: Click on the "System Properties" link at the left hand side of the RSM Home Screen to display the System Parameters menu as shown in Figure 5.4. From the System Parameters Menu, click on the "Real Time Clock" link to access the Real Time Clock menu.

The configuration menu for the Real Time Clock offers the following options:

• Date: Sets the Month, Date, Year and day of the week for the RSM’s real-time clock/calendar.

• Time: Sets the Hour, Minute and Second for the RSM’s real time clock/calendar. Key in the time using the 24-hour (military) format.

• Time Zone: Sets the time zone, relative to Greenwich Mean Time. Note that the Time Zone setting will function differently, depending on whether or not the NTP feature is enabled and properly configured. (Default = GMT (No DST).)

◆

NTP Enabled: The Time Zone setting is used to adjust the Greenwich Mean

Time value (received from the NTP server) to determine the precise local time for the selected time zone.

◆

NTP Disabled: If NTP is disabled, or if the RSM is not able to access the NTP

server, then status screens and activity logs will list the selected Time Zone and current Real Time Clock value, but will not apply the correction factor to the displayed Real Time Clock value.

• NTP Enable: When enabled, the RSM will contact an NTP server (defined via the NTP IP Address prompts) once a day, and update its clock based on the NTP server time and selected Time Zone. (Default = Off.)

Notes:

• The RSM will also contact the NTP server and update the time whenever you

change NTP parameters.

• To command the RSM to immediately contact the NTP server at any time,

make certain that the NTP feature is enabled and configured, then type /F and press [Enter]. When the System Parameters menu appears, press [Esc]. The RSM will save parameters and then attempt to contact the server, as specified by currently defined NTP parameters.

• Primary NTP Address: Defines the IP address or domain name (up to 64 characters long) for the primary NTP server. (Default = undefined.)

5-7

Configuration

• Secondary NTP Address: Defines the IP address or domain name (up to 64 characters long) for the secondary, fallback NTP Server. (Default = undefined.)

• NTP Timeout: The amount of time in seconds, that will elapse between each attempt to contact the NTP server. When the initial attempt is unsuccessful, the RSM will retry the connection four times. If neither the primary nor secondary NTP server responds, the RSM will wait 24 hours before attempting to contact the NTP server again. (Default = 3 Seconds.)

5.4.2. The Invalid Access Lockout Feature

When properly configured and enabled, the Invalid Access Lockout feature will watch all login attempts made at all RSM ports. If a given port exceeds the selected number of invalid attempts, then that port will be automatically disabled for a user-defined length of time. The Invalid Access Lockout feature uses three separate counters to track invalid access attempts:

• Serial Port Counter: Counts invalid access attempts at each individual serial port. If the number of invalid attempts at a given port exceeds the user-defined Lockout Attempts value, then that port will be locked.

• Raw Socket Counter: Counts invalid attempts to connect to a port via Raw Socket protocol. If the number of invalid attempts at a given port exceeds the user-defined Lockout Attempts value, then Raw Socket connections to that port will be locked.

• Telnet, SSH and Web Browser Counter: Counts all invalid attempts to access command mode via Telnet, SSH or Web Browser interface. If the number of cumulative invalid attempts exceeds the user-defined Lockout Attempts value, then the Network Port will be locked.

Note that when an Invalid Access Lockout occurs, you can either wait for the Lockout Duration period to elapse (after which, the RSM will automatically reactivate the port), or you can issue the /UL command (type /UL and press [Enter]) via the Text Interface to instantly unlock all RSM serial ports.

Notes:

• Invalid Access Lockout parameters, defined via the System Parameters

menu, will apply to all RSM serial ports.

• When a Port is locked, an external modem connected to that port will not

answer.

• When a given RSM serial port is locked, the other RSM serial ports will

remain unlocked, unless the Invalid Access Lockout feature has been triggered at those other ports.

• If any one of the RSM’s logical network ports is locked, all other network

connections to the unit will also be locked.

• All invalid access attempts at the RSM Network Port are cumulative (the count

for invalid access attempts is determined by the total number of all invalid attempts at all 64 logical network ports.) If a valid login name/password is entered at any of the logical network ports, then the count for all RSM logical network ports will be restarted.

• A Port that has been locked by the Invalid Access Lockout feature will still

respond to the ping command (providing that the ping command has not been disabled.)

5-8

Configuration

The Invalid Access menus allow you to select the following:

• Lockout Enable: Enables/Disables the Invalid Access Lockout feature. (Default = On.)

• Lockout Attempts: The number of invalid attempts required to activate the Invalid Access Lockout feature. (Default = 9.)

• Lockout Duration: The length of time ports will remain locked when an Invalid Access Lockout occurs. If the duration is set at "Infinite", then ports will remained locked until the /UL command is issued. (Default = 30 Minutes.)

5.4.3. The Audit Log

This feature allows you to create a record of command activity at all RSM ports. Audit Log records will include the time, date, username, and a brief description of each logged event (e.g., Connect, Login, etc.) The Audit Log is enabled and configured via the System Parameters Menus as described in Section 5.4.

The System Parameters Menus includes three different options for Audit Log configuration; Off (Audit Log disabled), "On with Syslog" and "On without Syslog." When "On with Syslog" is selected, each individual Audit Log record will be sent out to the user-defined Syslog IP Address as a Syslog message at the time that it is generated. The Syslog IP Address is defined via the Network Parameters Menu, as described in Section 5.8.

To read or erase the Audit Log, access command mode (via the Text Interface,) using an account and port that permit Supervisor commands, type /A s, press [Enter] (where s is an optional text string that you wish to search for,) and follow the instructions in the resulting submenu. When the s (search string) option is included, the /A command will return only those records that match the selected search string.

Notes:

• The RSM dedicates a fixed amount of internal memory for Audit Log records,

and if log records are allowed to accumulate until this memory is filled, memory will eventually "wrap around," and older records will be overwritten by newer records.

• The Audit Log cannot be viewed via the Web Browser Interface.

• When the

s option is used to search for all records that contain a specific text string, the Delete function will still delete all Audit Log records; the Delete function is not limited to the records that are currently displayed on screen.

Configuration

5.4.4. Callback Security

The Callback function provides an additional layer of security when callers attempt to access command mode via modem. When this function is properly configured, modem users will not be granted immediate access to command mode upon entering a valid password; instead, the unit will disconnect, and dial a user-defined number before allowing access via that number. If desired, users may also be required to re-enter the password after the RSM dials back.

In order for Callback Security to function properly, you must first enable and configure the feature via the System Parameters menus as described in this section, and then define a callback number for each desired user account as described in Section 5.6. To configure and enable the Callback function, proceed as follows:

• Text Interface: Type /F and press [Enter] to access the System Parameters menu, then type 6 and press [Enter] to display the Callback Security Menu.

• Web Browser Interface: Click the "System Properties" link on the left hand side of the screen to access the System Configuration menu, then click the "Configure Callback Security" link to display the Callback Security Menu.

In both the Text Interface and Web Browser Interface, the Callback Security Menu offers the following options:

• Callback Enable: This prompt offers five different configuration options for the Callback Security feature: (Default = On - Callback (Without Password Prompt.)

◆

Off: All Callback Security is disabled.

◆

On - Callback (Without Password Prompt): Callbacks will be performed for

user accounts that include a Callback Number, and the login prompt will not be displayed when the user’s modem answers. If the account does not include a Callback Number, that user will be granted immediate access and a Callback will not be performed.

◆

On - Callback (With Password Prompt): Callbacks will be performed for user

accounts that include a Callback Number, and the login prompt will be displayed when the user’s modem answers (accounts that include a Callback Number will be required to re-enter their username/password when their modem answers.) If the account does not include a Callback Number, then that user will be granted immediate access and a Callback will not be performed.

5-10

Configuration

◆

On - Callback ONLY (Without Password Prompt): Callbacks will be performed

for user accounts that include a Callback Number, and the username/password prompt will not be displayed when the user’s modem answers. Accounts that do not include a Callback Number will not be able to access command mode via an RSM modem port.

◆

On - Callback ONLY (With Password Prompt): Callbacks will be performed

for user accounts that include a Callback Number, and the username/password prompt will be displayed when the user’s modem answers (users will be required to re-enter their username/password when their modem answers.) Accounts that do not include a Callback Number will not be able to access command mode via an RSM modem port.

• Callback Attempts: The number of times that the RSM will attempt to call the Callback number. (Default = 3 attempts.)

• Callback Delay: The amount of time that the RSM will wait between Callback attempts. (Default = 30 seconds.)

Notes:

• After configuring and enabling Callback Security, you must then define a

callback phone number for each desired user account (as described in Section 5.6) in order for this feature to function properly.

• When using the "On - Callback (With Password Prompt)" option, it is

important to always define a callback number for each user account. Otherwise accounts that do not include a callback number will be allowed to immediately access command mode, and the callback function will not be performed.
