LinuxQuestions.org - SNMP conundrum

Hi,

Running Fedora 11 with following SNMP packages installed:

net-snmp-utils-5.4.2.1-10.fc11.i586
net-snmp-5.4.2.1-10.fc11.i586
net-snmp-libs-5.4.2.1-10.fc11.i586

When I run a simple snmpwalk:

[root@system ~]# snmpwalk -v 2c -c public localhost system
SNMPv2-MIB::sysDescr.0 = STRING: Linux steve 2.6.29.4-167.fc11.i686.PAE #1 SMP Wed May 27 17:28:22 EDT 2009 i686

SNMPv2-MIB::sysORUpTime.1 = Timeticks: (54) 0:00:00.54

SNMPv2-MIB::sysORUpTime.8 = Timeticks: (54) 0:00:00.54

Things look ok but when i try a:

[root@system snmp]# snmpwalk -v 2c -c public localhost 1

The output is the same except for an additonal line:

HOST-RESOURCES-MIB::hrSystemUptime.0 = Timeticks: (164543) 0:27:25.43
HOST-RESOURCES-MIB::hrSystemUptime.0 = No more variables left in this MIB View (It is past the end of the MIB tree)

When I try:

root@system snmp]# snmpwalk -v 2c -c public localhost hrDiskStorageTable
HOST-RESOURCES-MIB::hrDiskStorageTable = No more variables left in this MIB View (It is past the end of the MIB tree)

or

[root@system mibs]# snmpwalk -v 2c -c public localhost ifAdminStatus
IF-MIB::ifAdminStatus = No Such Object available on this agent at this OID

Basically, I am unable to retrieve any information past the 'system' group for any specific OID. Ive run countless snmpwalk's and snmpget's to no avail. I have made no amendments to the snmpd.conf file so suspect some kind of permission problem or something silly ive overlooked.

An snmptranslate shows:

[root@steve mibs]# snmptranslate .1.3.6.1.2.1.2.2.1.2
IF-MIB::IfDescr

Basically what I am trying to do is retrieve the information on the status of a network interface and feed into Servers Alive but am hitting a brick wall at every turn.

We already monitor diskspace and processes via add-on's but are struggling configuring SNMP. Unfortunately it seem's Servers Alive is far more Windows orientated so may have to revert to Big Brother or Nagios...

Thanks in advance.
