修改SNMP连接串

#ls -l /usr/sbin/snmpd

如果指向version 1的snmp，则配置文件为/etc/snmpd.conf。修改public的方法如下：

Edit the /etc/snmpd.conf and change the line:

Old: community public

New: community <new_comm_name>

如果指向version 3的snmp，则配置文件为/etc/snmpdv3.conf。修改public的方法如下：

Edit the /etc/snmpdv3.conf and change these lines from:

Old: VACM_GROUP group1 SNMPv1 public -

New: VACM_GROUP group1 SNMPv1 <new_comm_name> -

Old: TARGET_PARAMETERS trapparms1 SNMPv1 SNMPv1 public noAuthNoPriv -

New: TARGET_PARAMETERS trapparms1 SNMPv1 SNMPv1 <new_comm_name>

noAuthNoPriv -

Old: COMMUNITY public public noAuthNoPriv 0.0.0.0 0.0.0.0 -

New: COMMUNITY <new name> <new name> noAuthNoPriv 0.0.0.0 0.0.0.0 -

上述修改之后，重启snmpd服务：

# stopsrc -s snmpd

# startsrc -s snmpd

# lssrc -s snmpd ---should be active

将hostmibd和aixmibd配置成使用新的community name：

# stopsrc -s hostmibd

# stopsrc -s aixmibd

# startsrc -s hostmibd -a "-c <new_community_name>"

# startsrc -s aixmibd -a "-c <new_community_name>"

# lssrc -s hostmib ---should be active

# lssrc -s aixmibd ---should be active
