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 ESX 4.X Operating
Systems To Proxy VMware MIBs
The ESX 4.X server can be managed through a single default port 162 using the SNMP protocol. To do
this,
snmpd is configured to use the default port 162 and vmwarehostd is configured to use a different
(unused) port, for example, 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.
