[c-nsp] help on snmp mib

[teklay gebremichael]

hello,
i have a nagios server monitoring some of my servers. i am using snmp plugin to check some services. my problem is i can't find any mib data other than the .iso.org.dod.internet.mgmt.mib-2.system from my  ubuntu machine where i have installed the snmp and can access all the info under the system mib.
at the end of the snmpwalk, it says End of MIB as the shown below.
.............
.iso.org.dod.internet.mgmt.mib-2.system.sysORTable.sysOREntry.sysORUpTime.3 = Timeticks: (0) 0:00:00.00
.iso.org.dod.internet.mgmt.mib-2.system.sysORTable.sysOREntry.sysORUpTime.4 = Timeticks: (0) 0:00:00.00
.iso.org.dod.internet.mgmt.mib-2.system.sysORTable.sysOREntry.sysORUpTime.5 = Timeticks: (0) 0:00:00.00
.iso.org.dod.internet.mgmt.mib-2.system.sysORTable.sysOREntry.sysORUpTime.6 = Timeticks: (0) 0:00:00.00
.iso.org.dod.internet.mgmt.mib-2.system.sysORTable.sysOREntry.sysORUpTime.7 = Timeticks: (0) 0:00:00.00
.iso.org.dod.internet.mgmt.mib-2.system.sysORTable.sysOREntry.sysORUpTime.8 = Timeticks: (0) 0:00:00.00
End of MIB


but i got it working from my sun servers(mib like mib-2.host and others ). where i have put the same access from the snmp config. can any one help what i am missing?
thanks in adavance.
