ssh tunneling+cacti監(jiān)控遠(yuǎn)程主機(jī) 問題

通過cacti監(jiān)控本地主機(jī)，是沒問題。想通過ssh tunneling來開通到遠(yuǎn)程主機(jī)10.10.10.8的一個通道。通過ssh mysql@10.10.10.8是正常能登錄的。

ssh tunneling命令如下：

ssh -N -L 16000:127.0.0.1:161 -L 16001:127.0.0.1:11211 mysql@10.10.10.8 >> /tmp/tunnel.log &

在10.10.10.8遠(yuǎn)程主機(jī)通過snmpwalk命令正常顯示net-snmp信息。
[mysql@edm ~]$ snmpwalk -v 1 127.0.0.1 -c public system

其中cacti設(shè)置遠(yuǎn)程主機(jī)10.10.10.8參數(shù)如下：

Description: 10.10.10.8
Hostname: 10.10.10.8
Host Template: ucd/net SNMP Host
SNMP Community: public
SNMP Version: Version 1
SNMP Port: 16000


遠(yuǎn)程主機(jī)10.10.10.8的snmp.conf如下：
#       sec.name  source          community
com2sec notConfigUser  127.0.0.1       public

####
# Second, map the security name into a group name:

#       groupName      securityModel securityName
group   notConfigGroup v1           notConfigUser
group   notConfigGroup v2c           notConfigUser

####
# Third, create a view for us to let the group have rights to:

# Make at least  snmpwalk -v 1 localhost -c public system fast again.
#       name           incl/excl     subtree         mask(optional)
#view    systemview    included   .1.3.6.1.2.1.1
#view    systemview    included   .1.3.6.1.2.1.25.1.1
view all included   .1

####
# Finally, grant the group read-only access to the systemview view.

#       group          context sec.model sec.level prefix read   write  notif
access  notConfigGroup ""      any       noauth    exact  all none none




問題：cacti的10.10.10.8主機(jī)設(shè)置，一直指示SNMP ERROR。我想可能是ssh tunneling的問題，通過snmpwalk -v 1 127.0.0.1:16000 -c public system，沒net-snmp信息顯示。。。不知道有兄弟有沒有遇到過，請教，謝謝�。�！
