Installing and Configuring an SNMP Agent on the Linux Operating System
1.
Install the LSI SAS SNMP Agent using rpm -ivh <sas rpm>.
After installation, the LSI-AdapterSAS.mib SAS MIB file is in the /etc/lsi_mrdsnmp/sas directory.
This RPM makes the necessary modification needed in the snmpd.conf file to run the agent.
NOTE Before installation, check if there is any pass command that starts with 1.3.6.1.4.1.3582 OID in the snmpd.conf file.If so, delete all of the old pass commands that start with 1.3.6.1.4.1.3582 OID. This situation can occur if an earlier version of LSI SNMP Agent was installed in the system.
The snmpd.conf file structure should be the same as lsi_mrdsnmpd.conf. For reference, a sample conf file (lsi_mrdsnmpd.conf) is in the /etc/lsi_mrdsnmp directory.
com2sec snmpclient 172.28.136.112 public
In this example, the IP address of the remote machine is 172.28.136.112.
3.
To receive an SNMP trap to a particular machine, add the IP address of that machine to the com2sec section of the snmpd.conf file.
For example, to get a trap in 10.0.0.144, add the following to the snmpd.conf file.
# sec.name source communitycom2sec snmpclient 10.0.0.144 public
5.
To start or stop the SAS SNMP Agent daemon before issuing a SNMP query, enter the following command:
/etc/init.d/lsi_mrdsnmpd start/stop
You can check the status of the SAS SNMP Agent daemon by entering the following command:
/etc/init.d/lsi_mrdsnmpd status
snmpwalk -v1 -c public localhost .1.3.6.1.4.1.3582
snmptrapd -P -F "%02.2h:%02.2j TRAP%w.%q from %A %v\n"
NOTE To receive a trap in a local machine with Net-SNMP version 5.3, you must modify the snmptrapd.conf file (generally located at /var/net-snmp/snmptrapd.conf). Add "disableAuthorization yes" in the snmptrapd.conf file and then run the sudo snmptrapd -P -F "%02.2h:%02.2j TRAP%w.%q from %A %v\n” command.It is assumed that the snmpd.conf file is located in the /etc/snmp directory for Red Hat operating system and the /etc directory for the SLES operating system. You can change the file location from the /etc/init.d/lsi_mrdsnmpd file.
You can install SNMP without the trap functionality. To do so, set the TRAPIND environment variable to N before running the RPM.
Before you install a new version, you must uninstall all previous versions.
For the SLES 10 operating system, perform these steps to run SNMP:
1.
Copy the /etc/snmp/snmpd.conf file to the /etc/snmpd.conf file.
2.
Modify the /etc/init.d/snmpd file, and change the SNMPDCONF=/etc/snmp/snmpd.conf entry to SNMPDCONF=/etc/snmpd.conf.
3.
Run LSI SNMP rpm.
