Wink snmpwalk not working for localhost


Hi Everybody,
I have ubuntu-8.04(2.6.24-23-generic) os and my network interface is only ipv6 i.e. on eth0 interface ipv6 address(2001:468::3) is available. I am able to get statistics of remote host-system by following command--->
# snmpwalk -v2c -c public udp6:[2000:ffff::192.168.1.2] system
But I am unable to get the statics of localhost and getting following output when i run this command
# snmpwalk -v2c -c public localhost system
o/p->Timeout: No Response from localhost
Please help me, where im doing wrong thing and how to get snmpwalk for localhost?
Thanks Alot...

Hello,

Do you have snmp server installed on your Ubuntu? That's a prerequisite in order to be able to query your localhost. If it doesn't have an snmpd in the ps -ef then there's nobody home on localhost to reply to your questions.

Kind regards,

Eric

No problem, glad to help out if I can.

Did you set the community string on the server-side? Is the snmp server accepting connections on localhost? Is localhost defined correctly in the hosts file? Check with netstat -al if it's listening...

Ya i have set the rocommunity on server side,localhost is also defined in /etc/hosts
I did "netstat -an | grep :161" and its listening on port no. 161,i dint understand ur 2nd question i.e. whether snmp server accepting connection on localhost?
shall i show you my /etc/snmp/snmpd.conf file? i checked "netstat -al" also but im not understanding its output.

Sure, if you send me your config file I'll take a look at it. Also the output of netstat -al would tell me something.

I'm leaving office in one hour (14:30). I'll try to take a look at it at home and if not then tomorrow.

Kind regards,

Eric
