snmp를 켜려면
community1 설정해주고 실행을 하면되는데
중단이면 당연히 응답을 해주는 애가 없으니 응답이 없는데
$ snmpwalk -v 2c -c test 192.168.10.1 Timeout: No Response from 192.168.10.1
snmp를 켜놓으면 한참 걸려서 먼가 나오긴 한다.
그런데 CPU 관련 문구는 없어서 cpu 사용량을 확인할 방법은 없는건가...

snmpget을 써보려는데 음.. AGENT와 OID가 필수라..
$ snmpget -v2c -c test 192.168.10.1 Missing object name USAGE: snmpget [OPTIONS] AGENT OID [OID]...
대충 위에서 나온걸로 해보는데 OID가 아니랜다.
$ snmpget -v2c -c test 192.168.10.1 iso.3.6.1.4.1.12874 iso.3.6.1.4.1.12874 = No Such Object available on this agent at this OID
딱 맞는걸 넣어야 나온다. 그래서 walk가 짱인가?
$ snmpget -v2c -c test 192.168.10.1 iso.3.6.1.2.1.2.1.0 iso.3.6.1.2.1.2.1.0 = INTEGER: 5
