# 01.02-Booting

由於執行 snmpd 需要 libnetsnmpagent.so.20，可是 libnetsnmpagent.so.20 並不在預設的路徑中，所以必須要 export libnetsnmpagent.so.20 所在的資料夾 /usr/local/lib，必須使用 root 權限才可以完成。

\[net-snmp-5.5]#sudo su -

\[root]# export LD\_LIBRARY\_PATH=/usr/local/lib

\[root]#snmpd

\[root]#exit // 切回一般使用者權限

\[net-snmp-5.5]#sudo chmod a+s /bin/nano

\[net-snmp-5.5]#export LD\_LIBRARY\_PATH=/usr/local/lib

\[net-snmp-5.5]#sudo snmpd

\[net-snmp-5.5]#sudo netstat -tuple

//查看snmpd是否已被開啟，如已正確開啟會和圖 3相同
