2 Setup And Administration Dell OpenManage Server Administrator provides security through role- based 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.
Instrumentation User, Power User, Administrator, Elevated Administrator Power User, Administrator, Elevated Administrator Remote Access User, Power User, Administrator, Elevated Administrator Administrator, Elevated Administrator Storage Management User, Power User, Administrator, Elevated Administrator Administrator, Elevated Administrator Authentication The Server Administrator authentication scheme ensures that the correct access types are assigned to the correct user privileges.
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.

• Configuring the SNMP Agent On Systems Running Supported VMware ESXi 4.X and ESXi 5.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, enable Set operations, and send traps to a management station.
6. Click OK to save the changes. Enabling SNMP Set Operations SNMP Set operations must be enabled on the Server Administrator system to change Server Administrator attributes using IT Assistant. 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 then click Services. 4. Scroll down the list of services until you find SNMP Service, right-click SNMP Service, and click Properties.
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 readonly access for the public community only to the MIB-II system branch (identified by the 1.3.
Enabling SNMP Set Operations SNMP Set operations must be enabled on the system running Server Administrator in order to change Server Administrator attributes using IT Assistant. To enable SNMP Set operations on the 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: access publicgroup "" any noauth exact all none none or access notConfigGroup "" any noauth exact all none none. 2.
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.
167. Any SNMP request on the VMware MIB branch is rerouted to the vmware-hostd using the proxy feature of the snmpd daemon. The VMWware SNMP configuration file can be modified manually on the ESX server or by running the VMware Remote Command-Line Interface (RCLI) command, vicfg-snmp, from a remote system (Windows or Linux). The RCLI tools can be downloaded from the VMware website at vmware.com/download/vi/drivers_tools.html. To configure the SNMP agent: 1.
