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 |

Ya snmpd server is installed on my ubuntu.I checked it by command " ps -A | grep snmp " and i got this line---> ps -A | grep snmp 6978 ? 00:00:00 snmpd |
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... |

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 |
