2013-11-04 Get SNMP(v3) working on Ubuntu 12.04

I am running an Ubuntu 12.04 as working environment on my local machine. Ubuntu 12.04 is latest LTS (Long Term Support) version so that it's a good choice for a server. I need to install SNMP on my machine recently and I install it by following command
1
sudo apt-get install snmpd snmp
Copied!
However it seems doesn't work. After checking the system log, I found the following errors in /var/log/syslog
1

So let's fix the problem. I comment the snmpd.conf configurations appeared in syslog, then use command cat /etc/snmp/snmpd.conf | grep -v '#' | grep -v '^\s*#x27; to get a clean version.
1

Copied!
After updated /etc/snmpd/snmpd.conf and /etc/init.d/snmpd restart, now it's working.
