Introduction

Server Administrator provides a comprehensive, one-to-one systems management solution in two ways: from an integrated, web browser-based graphical user interface (GUI) and from a command line interface (CLI) through the operating system. Server Administrator enables system administrators to manage systems locally and remotely on a network. It enables system administrators to focus on managing their entire network by providing comprehensive one-to-one systems management. In the context of Server Administrator, a system refers to a stand-alone system, a system with attached network storage units in a separate chassis, or a modular system consisting of one or more server modules in a modular enclosure. Server Administrator provides information about:

•Systems that are operating properly and systems that have problems

•Systems that require remote recovery operations

Server Administrator provides easy-to-use management and administration of local and remote systems through a comprehensive set of integrated management services. Server Administrator is the sole installation on the system being managed and is accessible both locally and remotely from the Server Administrator home page. Remotely monitored systems may be accessed through dial-in, LAN, or wireless connections. Server Administrator ensures the security of its management connections through role-based access control (RBAC), authentication, and secure socket layer (SSL) encryption.

Installation

You can install Server Administrator using the Dell Systems Management Tools and Documentation DVD. The DVD provides a setup program to install, upgrade, and uninstall Server Administrator, managed system and management station software components. Additionally, you can install Server Administrator on multiple systems through an unattended installation across a network. The Server Administrator installer provides installation scripts and RPM packages to install and uninstall Server Administrator and other managed system software components on your managed system. For more information, see the

Server Administrator Installation Guide and the Management Station Software Installation Guide at dell.com/opemanagemanuals.

NOTE: When you install the open source packages from the Dell Systems Management Tools and Documentation DVD, the corresponding license files are automatically copied to the system. When you remove these packages, the corresponding license files are also removed.

NOTE: If you have a modular system, you must install Server Administrator on each server module installed in the chassis.

Updating Individual System Components

To update individual system components, use component-specific Dell Update Packages. Use the Dell Server Update Utility DVD to view the complete version report and to update an entire system. The Server

Update Utility (SUU) identifies and applies the required updates to your system. SUU can also be downloaded from support.dell.com.

NOTE: For more information about obtaining and using the Server Update Utility (SUU), to update your Dell Systems or to view the updates available for any systems listed in the Repository, see the

Dell Server Update Utility User's Guide at dell.com/openmanagemanuals.

Storage Management Service

The Storage Management Service provides storage management information in an integrated graphical view.

NOTE: For more information about the Storage Management Service, see the Server Administrator Storage Management User's Guide at dell.com/openmanagemanuals.

Instrumentation Service

The Instrumentation Service provides rapid access to detailed fault and performance information gathered by industry-standard systems management agents and allows remote administration of monitored systems, including shutdown, startup, and security.

Remote Access Controller

The Remote Access Controller provides a complete remote system management solution for systems equipped with the Dell Remote Access Controller (DRAC) or Baseboard Management Controller (BMC)/ Integrated Dell Remote Access Controller (iDRAC) solution. The Remote Access Controller provides remote access to an inoperable system, allowing you to get the system up and running as quickly as possible. The Remote Access Controller also provides an alert notification when a system is down and allows you to remotely restart the system. Additionally, the Remote Access Controller logs the probable cause of system crashes and saves the most recent crash screen.

Logs

Server Administrator displays logs of commands issued to or by the system, monitored hardware events, and system alerts. You can view logs on the home page, print or save them as reports, and send them by e-mail to a designated service contact.

Systems Management Standards Availability

Server Administrator supports the following systems management protocols:

•HyperText Transfer Protocol Secure (HTTPS)

•Common Information Model (CIM)

•Simple Network Management Protocol (SNMP)

If your system supports SNMP, you must install and enable the service on your operating system. If SNMP services are available on your operating system, the Server Administrator installation program installs the supporting agents for SNMP.

HTTPS is supported on all operating systems. Support for CIM and SNMP is operating system dependent and, in some cases, operating system-version dependent.

NOTE: For information on SNMP security concerns, see the Server Administrator readme file (packaged with the Server Administrator application) or at dell.com/openmanagemanuals. You must apply updates from your operating system's master SNMP agents to ensure that Dell's SNMP subagents are secure.

Availability On Supported Operating Systems

On supported Microsoft Windows operating systems, Server Administrator supports two systems management standards: CIM/Windows Management Instrumentation (WMI) and SNMP, while on supported Red Hat Enterprise Linux and SUSE Linux Enterprise Server operating systems, Server Administrator supports the SNMP systems management standard.

Server Administrator adds considerable security to these systems management standards. All attributes set operations (for example, changing the value of an asset tag) must be performed with Dell OpenManage Essentials while logged in with the required privileges.

The following table shows the systems management standards that are available for each supported operating system.

Setup And Administration

Server Administrator provides security through rolebased access control (RBAC), authentication, and encryption for both the Web-based and command line interfaces.

Role-Based Access Control

RBAC manages security by determining the operations that can be executed by persons in particular roles. Each user is assigned one or more roles, and each role is assigned one or more privileges that are permitted to users in that role. With RBAC, security administration corresponds closely to an organization's structure.

User Privileges

Server Administrator grants different access rights based on the user's assigned group privileges. The four user privilege levels are: User, Power User, Administrator, and Elevated Administrator.

Table 2. User Privileges

User Privilege		Access	Description
Level		Type

	View	Manage
User	Yes	No	Users can view most information.
Power User	Yes	Yes	Power Users can set warning threshold values and
			configure which alert actions are to be performed when a
			warning or failure event occurs.
Administrator	Yes	Yes	Administrators can configure and perform shutdown
			actions, configure Auto Recovery actions in case a system
			has a non-responsive operating system, and clear
			hardware, event, and command logs. Administrators can
			also configure the system to send e-mails.
Elevated	Yes	Yes	Elevated Administrators can view and manage information.
Administrator
(Linux only)

Privilege Levels to Access Server Administrator Services

The following table summarizes the users who have privileges to access and manage Server Administrator services.

Server Administrator grants read-only access to users logged in with User privileges, read and write access to users logged in with Power User privileges, and read, write, and administrator access to users logged in with Administrator and Elevated Administrator privileges.

Table 3. Privileges Required To Manage Server Administrator Services
Service	User Privilege Level Required
	View	Manage
Instrumentation	User, Power User, Administrator,	Power User, Administrator,
	Elevated Administrator	Elevated Administrator
Remote Access	User, Power User, Administrator,	Administrator, Elevated
	Elevated Administrator	Administrator
Storage Management	User, Power User, Administrator,	Administrator, Elevated
	Elevated Administrator	Administrator

Authentication

The Server Administrator authentication scheme ensures that the correct access types are assigned to the correct user privileges. Additionally, when the command line interface (CLI) is invoked, the Server Administrator authentication scheme validates the context within which the current process is running. This authentication scheme ensures that all Server Administrator functions, whether accessed through the Server Administrator home page or CLI, are properly authenticated.

Microsoft Windows Authentication

On supported Microsoft Windows operating systems, Server Administrator uses Integrated Windows Authentication (formerly called NTLM) to authenticate. This authentication system allows Server Administrator security to be incorporated in an overall security scheme for your network.

Red Hat Enterprise Linux And SUSE Linux Enterprise Server Authentication

On supported Red Hat Enterprise Linux and SUSE Linux Enterprise Server operating systems, Server Administrator uses various authentication methods based on the Pluggable Authentication Modules (PAM) library. Users can log in to Server Administrator either locally or remotely using different account management protocols, such as LDAP, NIS, Kerberos, and Winbind.

VMware ESXi Server 5.X Authentication

ESXi Server authenticates users accessing ESXi hosts using the vSphere/VI Client or Software Development Kit (SDK). The default installation of ESXi uses a local password database for authentication. ESXi authentication transactions with Server Administrator are also direct interactions with the vmwarehostd process. To make sure that authentication works efficiently for your site, perform basic tasks such as setting up users, groups, permissions, and roles, configuring user attributes, adding your own certificates, and determining whether you want to use SSL.

NOTE: On systems running VMware ESXi Server 5.0 operating system, to login to Server Administrator, all users require Administrator privileges. For information on assigning roles, see the VMware documentation.

Encryption

Server Administrator is accessed over a secure HTTPS connection using secure socket layer (SSL) technology to ensure and protect the identity of the system being managed. Java Secure Socket Extension (JSSE) is used by supported Microsoft Windows, Red Hat Enterprise Linux, and SUSE Linux Enterprise Server operating systems to protect the user credentials and other sensitive data that is transmitted over the socket connection when a user accesses the Server Administrator home page.

Assigning User Privileges

To ensure critical system component security, assign user privileges to all Dell OpenManage software users before installing Dell OpenManage software. New users can log in to Dell OpenManage software using their operating system user privileges.

CAUTION: To protect access to your critical system components, assign a password to every user account that can access the Dell OpenManage software. Users without an assigned password cannot log in to Dell OpenManage software on a system running Windows Server 2003 due to the operating system design.

CAUTION: Disable guest accounts for supported Windows operating systems to protect access to your critical system components. Consider renaming the guest accounts so that remote scripts cannot enable the accounts using the default guest account names.

NOTE: For instructions on assigning user privileges for each supported operating system, see your operating system documentation.

NOTE: To add users to OpenManage software, add new users to the operating system. You do not have to create new users from within the OpenManage software.

Adding Users To A Domain On Windows Operating Systems

NOTE: You must have Microsoft Active Directory installed on your system to perform the following procedures. See Using the Active Directory Login for more information about using Active Directory.

1.Navigate to Control Panel → Administrative Tools → Active Directory Users and Computers.

2.In the console tree, right-click Users or right-click the container in which you want to add the new user, and then point to New → User.

3.Type the appropriate user name information in the dialog box, and then click Next.

4.Click Next, and then click Finish.

5.Double-click the icon representing the user that you just created.

6.Click the Member of tab.

7.Click Add.

8.Select the appropriate group and click Add.

9.Click OK, and then click OK again.

NOTE: New users can log in to Dell OpenManage software with the user privileges of their assigned group and domain.

Creating Server Administrator Users For Supported Red Hat Enterprise Linux and SUSE Linux Enterprise Server Operating Systems

Administrator access privileges are assigned to the user logged in as root. For information about creating users and user groups, see your operating system documentation.

NOTE: You must be logged in as root or an equivalent user to perform the procedures.

NOTE: You must have the useradd utility installed on your system to perform the procedures.

Configuring The SNMP Agent

Server Administrator supports the Simple Network Management Protocol (SNMP—a systems management standard—on all supported operating systems. The SNMP support may or may not be installed depending on your operating system and how the operating system was installed. In most cases, SNMP is installed as part of your operating system installation. An installed supported systems management protocol standard, such as SNMP, is required before installing Server Administrator.

You can configure the SNMP agent to change the community name and to send traps to a management station. To configure your SNMP agent for proper interaction with management applications such as the Dell OpenManage Essentials, perform the procedures described in the following sections.

NOTE: The default SNMP agent configuration usually includes a SNMP community name such as public. For security reasons, you must rename the default SNMP community names. For information about renaming the SNMP community names, see Changing The SNMP Community Name.

NOTE: For IT Assistant to retrieve management information from a system running Server Administrator, the community name used by IT Assistant must match a community name on the system running Server Administrator. For IT Assistant to modify information or perform actions on a system running Server Administrator, the community name used by IT Assistant must match a community name that allows Set operations on the system running Server Administrator. For IT Assistant to receive traps (asynchronous event notifications) from a system running Server Administrator, the system running Server Administrator must be configured to send traps to the system running IT Assistant.

The following procedures provide step-by-step instructions for configuring the SNMP agent for each supported operating system:

•Configuring the SNMP Agent For Systems Running Supported Windows Operating Systems

•Configuring the SNMP Agent On Systems Running Supported Red Hat Enterprise Linux

•Configuring the SNMP Agent On Systems Running Supported SUSE Linux Enterprise Server

•Configuring the SNMP Agent on Systems Running Supported VMware ESXi 5.X and ESXi 6.X Operating Systems

Configuring The SNMP Agent On Systems Running Supported Windows Operating Systems

Server Administrator uses the SNMP services provided by the Windows SNMP agent. You can configure the SNMP agent to change the community name and send traps to a management station. To configure your SNMP agent for proper interaction with management applications such as IT Assistant, perform the procedures described in the following sections.

NOTE: For additional details on SNMP configuration, see the operating system documentation.

Enabling SNMP Access On Remote Hosts (Windows Server 2003 Only)

Windows Server 2003, by default, does not accept SNMP packets from remote hosts. For systems running Windows Server 2003, you must configure the SNMP service to accept SNMP packets from remote hosts if you plan to manage the system by using SNMP management applications from remote hosts.

To enable a system running the Windows Server 2003 operating system to receive SNMP packets from a remote host:

1.Open the Computer Management window.

2.Expand the Computer Management icon in the window, if necessary.

5.Click the Security tab.

6.Select Accept SNMP packets from any host, or add the remote host to the Accept SNMP packets from these hosts list.

Changing the SNMP community name

NOTE: You cannot set the SNMP community name from Server Administrator. Set the community name using operating system SNMP tools.

Configuring the SNMP community names determines which systems are able to manage your system through SNMP. The SNMP community name used by management applications must match an SNMP community name configured on the system running Server Administrator so that the management applications can retrieve management information from Server Administrator.

1.Open the Computer Management window.

2.Expand the Computer Management icon in the window, if necessary.

3.Expand the Services and Applications icon and click Services.

4.Scroll down the list of services until you find SNMP Service, right-click SNMP Service, and then click

The SNMP Service Properties window is displayed.

To edit a community name:

a.Select a community name in the Accepted Community Names list and click Edit. The SNMP Service Configuration window is displayed.

b.Edit the community name in the Community Name box, and then click OK. The SNMP Service Properties window is displayed.

6.Click OK to save the changes.

Configuring Your System To Send SNMP Traps To A Management Station

Server Administrator generates SNMP traps in response to changes in the status of sensors and other monitored parameters. You must configure one or more trap destinations on the system running Server Administrator for SNMP traps to be sent to a management station.

1.Open the Computer Management window.

2.Expand the Computer Management icon in the window, if necessary.

3.Expand the Services and Applications icon and click Services.

4.Scroll down the list of services until you find SNMP Service, right-click SNMP Service , and then click

The SNMP Service Properties window appears.

5.Click the Traps tab to add a community for traps or to add a trap destination for a trap community.

a.To add a community for traps, type the community name in the Community Name box and click Add to list, which is located next to the Community Name box.

b.To add a trap destination for a trap community, select the community name from the

Community Name drop-down box and click Add under the Trap Destinations box. The SNMP Service Configuration window appears.

c.In the Host name, IP or IPX address box, type the trap destination, Add. The SNMP Service Properties window appears.

6.Click OK to save the changes.

Configuring The SNMP Agent On Systems Running Supported Red Hat Enterprise Linux

Server Administrator uses the SNMP services provided by the net-snmp SNMP agent. You can configure the SNMP agent to change the community name, enable Set operations, and send traps to a management station. To configure your SNMP agent for proper interaction with management applications such as IT Assistant, perform the procedures described in the following sections.

NOTE: For additional details on SNMP configuration, see the operating system documentation.

SNMP Agent Access Control Configuration

The management information base (MIB) branch implemented by Server Administrator is identified by the Object Identifier (OID) 1.3.6.1.4.1.674. Management applications must have access to this branch of the MIB tree to manage systems running Server Administrator.

For Red Hat Enterprise Linux and VMware ESXi 4.0 operating systems, the default SNMP agent configuration gives read-only access for the public community only to the MIB-II system branch (identified by the 1.3.6.1.2.1.1 OID) of the MIB tree. This configuration does not allow management applications to retrieve or change Server Administrator or other systems management information outside of the MIB-II system branch.

Server Administrator SNMP Agent Install Actions

If Server Administrator detects the default SNMP configuration during installation, it attempts to modify the SNMP agent configuration to give read-only access to the entire MIB tree for the public community. Server Administrator modifies the SNMP agent configuration file /etc/snm, p/snmpd.conf by:

•Creating a vew to the entire MIB tree by adding the following line if it does not exist: view all included

•Modifying the default access line to give read-only access to the entire MIB tree for the public community. Server Administrator looks for the following line: access notConfigGroup "" any noauth exact systemview none none

•If Server Administrator finds the above line, it modifies the line as: access notConfigGroup "" any noauth exact all none none

NOTE: To ensure that Server Administrator is able to modify the SNMP agent configuration for providing proper access to systems management data, it is recommended that any other SNMP agent configuration changes be made after installing Server Administrator.

Server Administrator SNMP communicates with the SNMP agent using the SNMP Multiplexing (SMUX) protocol. When Server Administrator SNMP connects to the SNMP agent, it sends an object identifier to the SNMP agent to identify itself as a SMUX peer. Because that object identifier must be configured with the SNMP agent, Server Administrator adds the following line to the SNMP agent configuration file, /etc/ snmp/snmpd.conf, during installation if it does not exist:

smuxpeer .1.3.6.1.4.1.674.10892.1

Changing The SNMP Community Name

Configuring the SNMP community name determines which systems are able to manage your system through SNMP. The SNMP community name used by management applications must match an SNMP community name configured on the system running Server Administrator, so that the management applications can retrieve management information from Server Administrator.

To change the SNMP community name used for retrieving management information from a system running Server Administrator:

1.Open the SNMP agent configuration file, /etc/snmp/snmpd.conf.

2.Find the line that reads: com2sec publicsec default public or com2sec notConfigUser default public.

NOTE: For IPv6, find the line com2sec6 notConfigUser default public. Also, add the text agentaddress udp6:161 in the file.

3.Edit this line, replacing public with the new SNMP community name. When edited, the new line should read: com2sec publicsec default community_name or com2sec notConfigUser default community_name.

4.To enable SNMP configuration changes, restart the SNMP agent by typing: service snmpd restart.

Configuring Your System To Send Traps To A Management Station

Server Administrator generates SNMP traps in response to changes in the status of sensors and other monitored parameters. One or more trap destinations must be configured on the system running Server Administrator for SNMP traps to be sent to a management station.

To configure your system running Server Administrator to send traps to a management station, edit the SNMP agent configuration file, /etc/snmp/snmpd.conf, and perform the following steps:

1.Add the following line to the file: trapsink IP_address community_name, where IP_address is the IP address of the management station and community_name is the SNMP community name.

2.To enable SNMP configuration changes, restart the SNMP agent by typing: service snmpd restart.

Configuring The SNMP Agent On Systems Running Supported SUSE Linux Enterprise Server

Server Administrator uses the SNMP services provided by the net-snmp agent. You can configure the SNMP agent to enable SNMP access from remote hosts, change the community name, enable Set operations, and send traps to a management station. To configure your SNMP agent for proper interaction with management applications such as IT Assistant, perform the procedures described in the following sections.

NOTE: For additional details on SNMP configuration, see the operating system documentation.

Sever Administrator SNMP Install Actions

Server Administrator SNMP communicates with the SNMP agent using the SMUX protocol. When Server Administrator SNMP connects to the SNMP agent, it sends an object identifier to the SNMP agent to identify itself as a SMUX peer. This object identifier must be configured with the SNMP agent, therefore, Server Administrator adds the following line to the SNMP agent configuration file, /etc/snmp/ snmpd.conf, during installation if it does not exist:

smuxpeer .1.3.6.1.4.1.674.10892.1

Enabling SNMP Access From Remote Hosts

The default SNMP agent configuration on SUSE Linux Enterprise Server operating systems gives read-only access to the entire MIB tree for the public community from the local host only. This configuration does not allow SNMP management applications such as IT Assistant running on other hosts to discover and manage Server Administrator systems properly. If Server Administrator detects this configuration during installation, it logs a message to the operating system log file, /var/log/messages, to indicate that SNMP access is restricted to the local host. You must configure the SNMP agent to enable SNMP access from remote hosts if you plan to manage the system by using SNMP management applications from remote hosts.

NOTE: For security reasons, it is advisable to restrict SNMP access to specific remote hosts if possible.

To enable SNMP access from a specific remote host to a system running Server Administrator, edit the SNMP agent configuration file, /etc/snmp/snmpd.conf, and perform the following steps:

1.Find the line that reads: rocommunity public 127.0.0.1.

2.Edit or copy this line, replacing 127.0.0.1 with the remote host IP address. When edited, the new line should read: rocommunity public IP_address.

NOTE: You can enable SNMP access from multiple specific remote hosts by adding a rocommunity directive for each remote host.

3.To enable SNMP configuration changes, restart the SNMP agent by typing: /etc/init.d/snmpd restart.

To enable SNMP access from all remote hosts to a system running Server Administrator, edit the SNMP agent configuration file, /etc/snmp/snmpd.conf, and perform the following steps:

4.Find the line that reads: rocommunity public 127.0.0.1.

5.Edit this line by deleting 127.0.0.1. When edited, the new line should read: rocommunity public.

6.To enable SNMP configuration changes, restart the SNMP agent by typing: /etc/init.d/snmpd restart.

Changing The SNMP Community Name

Configuring the SNMP community name determines which management stations are able to manage your system through SNMP. The SNMP community name used by management applications must match the SNMP community name configured on the system running Server Administrator,, so the management applications can retrieve the management information from Server Administrator.

To change the default SNMP community name used for retrieving management information from a system running Server Administrator:

1.Open the SNMP agent configuration file, /etc/snmp/snmpd.conf.

2.Find the line that reads: rocommunity public 127.0.0.1.

3.Edit this line by replacing public with the new SNMP community name. When edited, the new line should read: rocommunity community_name 127.0.0.1.

4.To enable SNMP configuration changes, restart the SNMP agent by typing: /etc/init.d/snmpd restart.

Configuring The SNMP Agent On Systems Running Supported VMware ESXi 5.X And ESXi 6.X Operating Systems

Server Administrator supports SNMP traps on VMware ESXi 5.X and ESXi 6.X. If a stand-alone license is only present, SNMP configuration fails on VMware ESXi operating systems. Server Administrator does not support SNMP Get and Set operations on VMWare ESXi 5.X and ESXi 6.X as the required SNMP support is unavailable. The VMware vSphere CommandLine Interface (CLI) is used to configure systems running VMware ESXi 5.X and ESXi 6.X to send SNMP traps to a management station.

NOTE: For more information about using the VMware vSphere CLI, see vmware.com/support.

Configuring Your System To Send Traps To A Management Station

To configure your ESXi system running Server Administrator to send traps to a management station:

1.Install the VMware vSphere CLI.

2.Open a command prompt on the system where the VMware vSphere CLI is installed.

3.Change to the directory where the VMware vSphere CLI is installed. The default location on Linux is /usr/bin. The default location on Windows is C:\Program Files\VMware\VMware vSphere CLI\bin.

4.Run the following command: vicfg-snmp.pl --server <server> --username <username> --password <password> -c <community> -t <hostname> @162/<community>

where <server> is the hostname or IP address of the ESXi system, <username> is a user on the ESXi system, <community> is the SNMP community name and <hostname> is the hostname or IP address of the management station.

NOTE: The extension .pl is not required on Linux.

NOTE: If you do not specify a user name and password, you are prompted. The SNMP trap configuration takes effect immediately without restarting any services.

Firewall Configuration On Systems Running Supported Red Hat Enterprise Linux Operating Systems And SUSE Linux Enterprise Server

If you enable firewall security while installing Red Hat Enterprise Linux/SUSE Linux, the SNMP port on all external network interfaces is closed by default. To enable SNMP management applications such as IT Assistant to discover and retrieve information from Server Administrator, the SNMP port on at least one external network interface must be open. If Server Administrator detects that the SNMP port is not open in the firewall for any external network interface, Server Administrator displays a warning message and logs a message to the system log.

You can open the SNMP port by disabling the firewall, opening an entire external network interface in the firewall, or opening the SNMP port for at least one external network interface in the firewall. You can perform this action before or after Server Administrator is started.

To open the SNMP port on Red Hat Enterprise Linux using one of the previously described methods:

1.At the Red Hat Enterprise Linux command prompt, type setup and press <Enter> to start the Text Mode Setup Utility.

NOTE: This command is available only if you have performed a default installation of the operating system.

The Choose a Tool menu appears.

2.Select Firewall Configuration using the down arrow and press <Enter>. The Firewall Configuration screen appears.

3.Press <Tab> to select Security Level and then press the spacebar to select the security level you want to set. The selected Security Level is indicated by an asterisk.

NOTE: For more information about the firewall security levels, press <F1>. The default SNMP port number is 161. If you are using the X Window System graphical user interface, pressing <F1> may not provide information about firewall security levels on newer versions of Red Hat Enterprise Linux.

a.To disable the firewall, select No firewall or Disabled and go to Step7.

b.To open an entire network interface or the SNMP port, select High, Medium, or Enabled and proceed to step 4.

4.Press <Tab> to go to Customize and press <Enter>. The Firewall Configuration-Customize screen appears.

5.Select whether to open an entire network interface or just the SNMP port on all network interfaces.

a.To open an entire network interface, press <Tab> to go to one of the Trusted Devices and press the spacebar. An asterisk in the box to the left of the device name indicates that the entire interface is opened.

b.To open the SNMP port on all network interfaces, press <Tab> to go to Other ports and type snmp:udp.

6.Press <Tab> to select OK and press <Enter> The Firewall Configuration screen appears.

7.Press <Tab> to select OK and press <Enter> The Choose a Tool menu appears.

8.Press <Tab> to select Quit and press <Enter>.

Firewall Configuration

To open the SNMP port on SUSE Linux Enterprise Server:

1.Configure SuSEfirewall2 by running the following command on a console: a.# yast2 firewall

2.Use the arrow keys to navigate to Allowed Services.

3.Press <Alt><d> to open the Additional Allowed Ports dialog box.

4.Press <Alt><T> to move the cursor to the TCP Ports text box.
