[hobbit]help needed

Hi all, I am trying to read the sysDescr from the snmp device, i wanted to know if i can reach the snmp device via snmp, and whether i am using the correct read only community string. But this is the error i get...any ideas on what am missing out or doing wrong?. TM:/home/hobbit/server/etc # snmpget -v1 -c afol-public TM [10.176.10.69] Error in packet Reason: (noSuchName) There is no such variable name in this MIB. Failed object: SNMPv2-TM::rfc1157Proxy.

Thanks
