snmpd를 올바르게 시작할 수 없습니다.

몇 가지 테스트를 수행하기 위해 ubuntu-server 15.10에서 snmp를 설정해 보았습니다. snmp를 다음과 같이 설치했습니다.

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

설치 후 다음 줄에 주석을 달았습니다 /etc/snmp/snmp.conf.

#mibs :

ubuntu-server 15.10에서 snmpd 프로세스를 시작하려고 하는데 그렇게 하면 실패합니다.

sudo service snmpd start

다음 오류가 발생합니다.

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

하지만 이렇게 하면 $ sudo /usr/sbin/snmpd -f해당 명령어로 동작하는지 확인하면서 서비스를 시작할 수 있습니다 snmpwalk. 그러나 다음과 같은 오류도 발생합니다.

$ sudo /usr/sbin/snmpd -f

해결책을 찾으려고 노력했지만 아무것도 찾지 못했습니다. 누구든지 도와줄 수 있나요?

또한 처음 두 명령의 출력을 복사하여 붙여넣었습니다.
