Hi,
First, I run "sudo snmpd" not "sudo snmp". Sorry for the typo.
I delete those duplicated lines and it works. So, I realize that the snmpd
should take care of this kind of issue.
Now, I run snmpget -c public -v2c localhost system.sysUpTime.0
It gives me the correct result.
But, I run snmpget -c public -v2c 137.99.10.108 system.sysUpTime.0
It says "Timeout: No response from 137.99.10.108"
"137.99.10.108" is my ip address.
I suppose both "localhost" and "ip address" would give me the result. but
why not?
Thanks,
Xian
