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 Command- Line Interface (CLI) is used to configure systems running
VMware ESXi 5.X and ESXi 6.X to send SNMP traps to a management station.
