Ubuntu上的snmpdconfiguration问题

关于Ubuntu服务器16.04 LTS上的snmpd服务的configuration,我有以下问题:

问题1:

/etc/snmp/snmpd.conf ,有一段评论:

 ############################################################################### # # SNMPv3 AUTHENTICATION # # Note that these particular settings don't actually belong here. # They should be copied to the file /var/lib/snmp/snmpd.conf # and the passwords changed, before being uncommented in that file *only*. # Then restart the agent 

注意They should be copied to the file /var/lib/snmp/snmpd.conf部分。

但是在/var/lib/snmp/snmpd.conf中还有另外一段评论:

 ############################################################################ # STOP STOP STOP STOP STOP STOP STOP STOP STOP # # **** DO NOT EDIT THIS FILE **** # # STOP STOP STOP STOP STOP STOP STOP STOP STOP ############################################################################ 

那么我应该在/var/lib/snmp/snmpd.conf创build用户吗?

问题2:

createUser的密码部分应该是明文还是摘要?
