This guide describe how to install and configure SNMP on Ubuntu.


root@netflow:/# sudo apt-get install snmpd

2. Configuration
Move existing /etc/snmp/snmpd.conf configuration file to /etc/snmp/snmpd.conf.org

root@netflow:/# mv /etc/snmp/snmpd.conf /etc/snmp/snmpd.conf.org

Create a new /etc/snmp/snmpd.conf file:

# Configure Read-Only community and restrict who can connect
rocommunity COPUBLIC
rocommunity COPUBLIC

# Information about this host
sysLocation bdHUB Dhaka Bangladesh
sysContact noc@bdhub.com

# Which OSI layers are active in this host
# (Application + End-to-End layers)
sysServices 72

Make snmpd use the newly created file and make it listen to all interfaces:

Edit /etc/default/snmpd

root@netflow:/# vi /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’


# snmpd options (use syslog, close stdin/out/err).
#SNMPDOPTS=’-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid’
SNMPDOPTS=’-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid -c /etc/snmp/snmpd.conf’

and restart snmpd

root@netflow:/# /etc/init.d/snmpd restart

3. Test
Check SNMP is running

root@netflow:/# sudo netstat -ulnp | grep 161
udp 0 0* 28676/snmpd

Check the snmpstatus output

root@netflow:/# snmpstatus -c ‘COPUBLIC’ -v2c
