Supported Target Devices

A target device managed by the MergePoint 5224/5240 SP manager can be one of the following:

• An SP on a server. SPs are out

their servers.

• A server or other type of device that does not have an SP but that provides access to its

command line through a dedicated Ethernet port. This type of device includes servers that redirect their serial console output to dedicated Ethernet ports (which provide a type of access generally referred to as serial over LAN or SoL).

• A device with a dedicated Ethernet port that supports management access via Telnet, SSH,

SNMP or by means of the MergePoint 5224/5240 SP manager’s native IP access capability.

NOTE: The terms target device and connected device are used in this guide when referring to an SP, server or other connected device, unless otherwise stated.

-of-band management controllers that many vendors include in

MergePoint 5224/5240 SP Manager’s Advantages for Target Device

Management

The MergePoint 5224/5240 SP manager, also called the appliance, controls access to server

-management services that are provided by direct connected SPs and to other types of

services that may be provided by other connected devices without SPs. Connected and configured devices are referred to as target devices.

A MergePoint 5224/5240 SP manager may be managed and target devices may be accessed through DSView 3 management software, as described in the document Managing MergePoint 5224/5240 Service Processor Managers Using DSView 3 Management Software. Alternately, a standalone MergePoint 5224/5240 SP manager may be managed and its target devices may be accessed using the Web Manager or console connections.

When managed as a standalone, the MergePoint 5224/5240 SP manager provides a single source for authentication, authorization managed using DSView 3 management software, the DSView 3 software acts as the single source.

Whichever way users access the MergePoint 5224/5240 SP manager, users can manage multiple servers with SPs from a single point without having to learn how to use multiple SP interfaces. For example, power management is provided by most SPs but each SP has its own interface and its own commands for power management. The MergePoint 5224/5240 SP manager allows an authorized user to manage power on multiple servers with SPs from multiple vendors using a single interface and a single set of power commands.

The security features provided by the MergePoint 5224/5240 SP manager work together to create a secure path between a user and a managed server or target device.

Chapter 1: Introduction 3

Figure 1.1 is a conceptual illustration of a secure path between a remote user and an SP through the MergePoint 5224/5240 SP manager. A remote user is shown, but users may also be locally located, on the same LAN. In Figure 1.1, the remote user accesses the MergePoint 5224/5240 SP manager through a network connection to the public Ethernet port. Users may also dial into the MergePoint 5224/5240 SP manager through an optional external modem or PC modem card.

Public Network Ethernet Port

Private Network Ethernet Port

Server

In Figure 1.1, the dedicated Ethernet port of an SP is separate from the server’s Ethernet ports. The SP’s dedicated Ethernet port is connected to one of the SP manager’s private Ethernet ports.

The IP address of the public Ethernet port is the only publicly defined IP address used for out

-of-band management of all connected SPs, which reduces the deployment costs for the SPs.

Each target device is configured with a private designated IP address and, at the administrator’s discretion, each target device may also have a virtual IP address. If virtual addresses are defined, users may be allowed to see a target device’s virtual IP address but not to see the target device’s privately defined IP address.

After the user selects the desired management action, the MergePoint 5224/5240 SP manager then creates a secure connection between the user and the SP, acting as a proxy on behalf of the user. While the user is performing any SP management action, the connection between the MergePoint 5224/5240 SP manager and the SP is kept separate and protected from the connection between the user and the MergePoint 5224/5240 SP manager. Nothing that happens on the private network is exposed to the public network. Depending on the mode of access (either by browser or by SSH), either HTTPS or SSH is always being used to protect communications that are transported on the public network between the user and the MergePoint 5224/5240 SP manager.

4 MergePoint 5224/5240 Service Processor Manager User Guide

Web Manager

The Web Manager may be used when the MergePoint 5224/5240 SP manager is managed as a standalone. If the MergePoint 5224/5240 SP manager is managed through DSView 3 management software, access to the Web Manager is usually disabled.

When the Web Manager is enabled, both authorized and administrative users can launch the Web Manager from a supported browser using HTTP or HTTPS. Authorized users can use the Web Manager to perform management actions on target devices, manage power on devices plugged into optional Intelligent Power Distribution Units (IPDUs) and change their own passwords. Only administrative users have access to the MergePoint 5224/5240 SP manager screens used for configuring users or target devices.

See Chapter 3 for information about using the Web Manager that is required for authorized and administrative users.

Browser access to the Web Manager is achieved in one of the following ways:

• Through the Ethernet port

• Through dialing into one of the modem or PC phone card types described in Dial-in Access on

page 19

Types of Users

Two predefined administrators are root and admin, and they cannot be deleted. Either root or admin can add regular user accounts and can authorize users to access management features on target devices. Any regular users added to the admin group become administrative users able to perform MergePoint 5224/5240 SP manager administration as described in the MergePoint 5224/5240 Service Processor Manager Installer and Administrator Guide. The default password for root and admin is cyclades and should be changed immediately to prevent unauthorized access.

The admin user (and any optionally added administrative users) can do the following:

• Access the Web Manager and use any of its functions

• Access the MergePoint 5224/5240 SP manager’s console and use the unrestricted shell

• Invoke the MergePoint 5224/5240 SP manager configuration utility, cli

• Invoke any Linux commands available to the non

• Invoke any Linux commands available to the root user by using the sudo command The root user can do the following:

• Access the MergePoint 5224/5240 SP manager’s console and use the unrestricted shell

• Invoke the MergePoint 5224/5240 SP manager configuration utility, cli

• Invoke any Linux commands available to the root user The root user cannot access the Web Manager.

-root user

Chapter 1: Introduction 5

Only one administrative user can be connected to the MergePoint 5224/5240 SP manager at a time. Regular users may be authorized for access to management features available on the connected SPs

or other types of target devices.

NOTE: The administrator may create and enable a custom security profile that has the override authorization feature set, which causes all authenticated users to have all access to all target devices. For details, see

Profiles’ Effects on Users’ Actions on page 14.

Events are messages logged when system management events are detected. The events can be logged either by the SP or by the server. Table 1.3 shows the event log management option names and command names used when you are logged into the Web Manager, when you have selected a target device from the spshell menu on the MergePoint 5224/5240 SP manager console and when you are entering the ssh command on a remote workstation. These options display the system event log (SEL) menu from the server where the SP resides. The user can view or clear event logs directly on the SP using the ssh command. All options are only available for managed servers with SPs.

Access to native features on a target device

Both Native IP and DirectCommand management options provide native access to target devices and enable an authorized user to connect directly either to the web management interface of a target device or to the command line of a device that redirects console output to a dedicated Ethernet port. When users are configured for target device management actions, the same permission authorizes the user for both Native IP and DirectCommand.

The authorized user obtains authenticated access to a target device’s native features such as native applications, integrated web servers and other proprietary interfaces that are available over IP. Native applications are proprietary SP management applications provided by some server vendors, such as HP InSight Manager, IBM Director and Dell Open Manage. Access to a native application usually requires the application to be installed on the user’s workstation. Some management applications reside on the SP itself.

Access to native functions on some SPs is through a proprietary web interface on the SP. HP iLO, Dell DRAC and IBM RSA II SPs have a local web server running and provide a web interface that allows administrators remote access for provisioning, monitoring and managing the server. The web interface is accessed through a specific port number. The monitoring and management features supported by some SPs through native web interfaces include access to the server’s serial or graphical user interface, power control, access to sensor data and server event logs, SNMP agents and virtual media.

management options

• View event log

• Clear event log

• Displays the event log

• Clears the event log

DirectCommand requirements

The DirectCommand option is available only through the Web Manager. DirectCommand creates a Java applet that runs in the background to start a secure SSH tunnel and to connect to the native web interface on the target device. Therefore, the Java Runtime Environment must be installed on the user’s workstation. The JRE is also a requirement for Web Manager access.

The Web Manager allows the administrator to configure up to 20 ports and associate them with other services that may also be invoked by DirectCommand. As described in the troubleshooting appendix in the installer and administrator guide, the administrator must take care to ensure that local applications are not using the same TCP ports that are used by DirectConnect.

8 MergePoint 5224/5240 Service Processor Manager User Guide

Native IP requirements

Native IP access requires a pre-existing secure tunnel between the user’s workstation and the MergePoint 5224/5240 SP manager. Table 1.5 shows the native IP parameters and command names available when you are logged into the Web Manager, when you have selected a target device from the spshell menu on the MergePoint 5224/5240 SP manager console and when you are entering the ssh command on a remote workstation.

Table 1.5: Native IP Management Options

Method Parameter or Command Name

Web Manager Native IP spshell menu in the MergePoint 5224/5240 SP manager

console ssh command • nativeipon

• Enable native IP

• Disable native IP

• nativeipoff

After an authenticated and authorized user establishes a secure tunnel and selects the Native IP option, the user can bring up a native web interface or launch a native web management application from where it resides on the user's workstation or from the SP’s console.

Native IP access depends on the following being true:

• The SP must provide the desired native management functionality. For example, SPs using IPMI protocols do not provide native web access.

• The user is authorized to access the Native IP option on an SP.

• The user has created a secure tunnel to the MergePoint 5224/5240 SP manager. An SSH tunnel gives access to native web applications only while a VPN tunnel gives access to both native web and native management applications.

Tasks for creating secure tunnels and obtaining native IP access

See Chapter 2 for creating information on creating secure tunnels and obtaining Native IP access.

Power management options

Table 1.6 shows the power management option names and command names used when you are logged into the Web Manager, when you have selected a target device from the spshell menu on the MergePoint 5224/5240 SP manager console and when you are entering the ssh command on a remote workstation. The power management options are only available for managed servers with SPs.

Reset commands

Table 1.8 shows the reset options available when you are logged into the Web Manager, when you have selected a target device from the spshell menu on the MergePoint 5224/5240 SP manager console and when you are entering the ssh command on a remote workstation. The reset management options are only available for managed servers with SPs.

Table 1.8: Reset Options

Method Command or Option

Web Manager Reset spshell menu in the MergePoint 5224/5240 SP

manager console ssh command reset

The effects of the reset command differ from one vendor’s SP to another and sometimes between firmware versions from the same vendor. In addition, some SPs have more than one type of reset, as described in the following list:

• Warm reset (or warm boot): only the server’s operating system is restarted

• Cold boot: the server is fully restarted (the same effect as issuing a Power cycle command) If an SP has more than one type of reset option, the MergePoint 5224/5240 SP manager Reset

command performs the highest level of reset: the cold boot option if available. If the administrator is configuring an SP that provides multiple reset options, the administrator can

customize an associated SP management script to cause the reset command to perform one of the lower levels of reset available on the SP. Customizing SP management scripts is described in the MergePoint 5224/5240 Service Processor Manager Installer and Administrator Guide.

Sensor management options

An authorized user or administrative user can view graphical displays of sensor data collected from servers by their SPs. These users can also modify graph display settings through the Web Manager or the user shell menu or by using the ssh command with the sensor commands.

Figure 1.2 shows an example graph. The sensor va l ue in a graph’s heading varies with the type of data being measured and the type of SP. The example fan sensor reading in Figure 1.2 has a heading Time Vs. % because the sensor is measuring the percentage of total possible fan speed. Examples of other possible values for sensor_value are Volts, Degrees Centigrade and Degrees Fahrenheit.

Table 1.10 shows the sensor management options available when you are logged into the Web Manager, when you have selected a target device from the spshell menu on the MergePoint 5224/ 5240 SP manager console and when you are entering the ssh command on a remote workstation. The sensor options display unformatted sensor data collected from the server by its SP. The page that appears provides a button that when clicked displays graphs of data from individual sensors.

Chapter 1: Introduction 13

The sensor management options are only available for managed servers with SPs.

Authentication

Anyone accessing the MergePoint 5224/5240 SP manager must log in by entering a username and password. Controlling access by requiring users to enter names and passwords is called authentication. The usernames and passwords entered during login attempts are checked against a database. Access is denied if the username or password is not valid.

The password database being checked can reside either locally (on the MergePoint 5224/5240 SP manager) or on an authentication server on the network.

The user is required to enter a username and password in the following cases:

• When logging into the MergePoint 5224/5240 SP manager. The authentication method chosen for the MergePoint 5224/5240 SP manager is used for all

access through Telnet, SSH or the Web Manager. By default, logins to the MergePoint 5224/ 5240 SP manager use local authentication.

• When accessing an SP or other target device.

Users may be required to enter different usernames and passwords when accessing the MergePoint 5224/5240 SP manager than when accessing a target device.

Security Profiles’ Effects on Users’ Actions

When the MergePoint 5224/5240 SP manager is being managed without DSView 3 management software, the administrator needs to select a security profile based on the security requirements of the organization.

NOTE: All of the features and procedures described in this guide work when the Moderate security profile is in effect.

Table 1.11: Services and Other Functions Controlled by Security Profiles

Service Other Functions That May Be Allowed/Disallowed

FTP N/A HTTP, HTTPS Redirect HTTP automatically to HTTPS ICMP N/A IPSec N/A PPTP N/A RPC N/A SNMP v1, v2c, v3 N/A SSH v1, SSH v2 Allow root login using SSH

Telnet Allow Telnet to MergePoint 5224/5240 SP manager

Assign an alternate port to SSH

Services may also be turned on and off independently from the security profile. For more details, see the MergePoint 5224/5240 Service Processor Manager Installer and Administrator Guide.

In addition to turning services on and off, an administrator may select the security profile option to override authorizations, which enables access based on authentication only.

NOTE: If you are prevented from using a service you need to use, such as FTP or SNMP, talk with the administrator to find out if the service can be enabled or if another way of performing a necessary task is available that is consistent with your site’s security policies.
