Cannot start snmpd correctly

Question

I trying to setup snmp in an ubuntu-server 15.10 to perform some tests. I have installed snmp as:

sudo apt-get install snmp snmpd snmp-mibs-downloader

After the installation I commented the following line in /etc/snmp/snmp.conf:

#mibs :

I am trying to start the process snmpd in the ubuntu-server 15.10 but it fails if I do:

sudo service snmpd start

I am having the following error:

Job for snmpd.service failed because the control process exited with error code. See "systemctl status snmpd.service" and "journalctl -xe" for details.

However if I do $ sudo /usr/sbin/snmpd -f I can start the service as I checked out that it works with the command snmpwalk. However, it also yields some errors:

$ sudo /usr/sbin/snmpd -f

Turning on AgentX master support.

I have tried to search for a solution but it I have not been able to find absolutely anything. Can somebody help?

Also I copy-paste the output of the two previous commands:

$ systemctl status snmpd.service

Solution

I fixed the same problem using this tutorial

You need to edit the file /etc/snmp/snmpd.conf changing the agentAddress directive accordingly. Then use createUser and rwuser, creating a user and giving it the adequate level of access respectively.

The should look like this.

#  Listen for connections from the local system only
#agentAddress  udp:127.0.0.1:161 # <= comment this line
#  Listen for connections on all interfaces (both IPv4 *and* IPv6)
agentAddress udp:161,udp6:[::1]:161

createUser bootstrap MD5 temp_password DES

rwuser bootstrap priv
rwuser demo priv

To the best of my knowledge you restart snmpd like so: /bin/systemctl restart snmpd
