我尝试在 ubuntu-server 15.10 中设置 snmp 来执行一些测试。我已将 snmp 安装为：
sudo apt-get install snmp snmpd snmp-mibs-downloader
安装后我评论了以下行/etc/snmp/snmp.conf：
#mibs :
我正在尝试在 ubuntu-server 15.10 中启动进程 snmpd 但如果我这样做就会失败：
sudo service snmpd start
我遇到以下错误：
Job for snmpd.service failed because the control process exited with error code. See "systemctl status snmpd.service" and "journalctl -xe" for details.
但是，如果我这样做，$ sudo /usr/sbin/snmpd -f我可以启动该服务，因为我检查它是否可以与该命令一起使用snmpwalk。然而，它也会产生一些错误：
$ sudo /usr/sbin/snmpd -f

Turning on AgentX master support.

我试图寻找解决方案，但我一无所获。有人可以帮忙吗？
我还复制粘贴前两个命令的输出：

我使用修复了同样的问题本教程
您需要编辑该文件/etc/snmp/snmpd.conf改变代理地址相应的指令。然后使用创建用户和RW用户，创建一个用户并分别为其授予足够的访问级别。
应该看起来像这样。
# 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
