SNMP: Instalasi & Konfigurasi di Ubuntu
Sumber: http://www.it-slav.net/blogs/2009/02/05/install-and-configure-snmp-on-ubuntu/
This guide describe howto install and configure SNMP on Ubuntu.
In an earlier article I have described howto set it up on RHES or CentOS, it is slightly different in Ubuntu.
1.Installation
root@ibsen:~# sudo apt-get install snmpd Reading package lists... Done Building dependency tree Reading state information... Done The following packages were automatically installed and are no longer required:
libmpich1.0gf libdc1394-22 genisoimage linux-headers-2.6.27-7 libgfortran2 dvd+rw-tools linux-headers-2.6.27-7-generic libcarp-clan-perl libxml-xql-perl libparse-yapp-perl rdate python-xml localechooser-data gcc-4.2-base libimage-size-perl libdebconfclient0 libvisual-0.4-0 libmyth-python perlmagick libvisual-0.4-plugins libavdevice52
Use 'apt-get autoremove' to remove them. The following extra packages will be installed:
libperl5.10 libsensors3 libsnmp-base libsnmp15
Suggested packages:
lm-sensors
The following NEW packages will be installed:
libperl5.10 libsensors3 libsnmp-base libsnmp15 snmpd

answer y
2. Configuration
Move existing /etc/snmp/snmpd.conf configuration file to /etc/snmp/snmpd.conf.org
mv /etc/snmp/snmpd.conf /etc/snmp/snmpd.conf.org
Create a new /etc/snmp/snmpd.conf file:
rocommunity public syslocation "PDC, Peters DataCenter" syscontact peter@it-slav.net
Make snmpd use the newly created file and make it listen to all interfaces:
Edit /etc/default/snmpd
Change from:
- snmpd options (use syslog, close stdin/out/err).
SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid 127.0.0.1'
To:
- snmpd options (use syslog, close stdin/out/err).
- SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid 127.0.0.1'
SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid -c /etc/snmp/snmpd.conf'
and restart snmpd
/etc/init.d/snmpd restart
3. Test
Do a snmpwalk from another host against your newly configured host.
[root@op5 ~]# snmpwalk -v 1 -c public -O e ibsen SNMPv2-MIB::sysDescr.0 = STRING: Linux ibsen 2.6.27-9-generic #1 SMP Thu Nov 20 21:57:00 UTC 2008 i686 SNMPv2-MIB::sysObjectID.0 = OID: NET-SNMP-MIB::netSnmpAgentOIDs.10 DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (68869) 0:11:28.69 SNMPv2-MIB::sysContact.0 = STRING: peter@it-slav.net SNMPv2-MIB::sysName.0 = STRING: ibsen SNMPv2-MIB::sysLocation.0 = STRING: "PDC, Peters DataCenter" SNMPv2-MIB::sysORLastChange.0 = Timeticks: (1) 0:00:00.01 SNMPv2-MIB::sysORID.1 = OID: SNMP-FRAMEWORK-MIB::snmpFrameworkMIBCompliance SNMPv2-MIB::sysORID.2 = OID: SNMP-MPD-MIB::snmpMPDCompliance SNMPv2-MIB::sysORID.3 = OID: SNMP-USER-BASED-SM-MIB::usmMIBCompliance SNMPv2-MIB::sysORID.4 = OID: SNMPv2-MIB::snmpMIB SNMPv2-MIB::sysORID.5 = OID: TCP-MIB::tcpMIB SNMPv2-MIB::sysORID.6 = OID: IP-MIB::ip
Yes it works!!
4. Monitor example
Below is an example of how it looks using op5 Monitor a Nagios based Enterprise Monitor solution.
