Getting Dell SNMP MIB to work on Debian?

Mon Jun 23 13:49:10 CDT 2008

Kevin,

As I've been experimenting with SNMP on Debian last week, I took one of 
our servers that didn't have SNMP installed and running and checked what 
steps I have to take to configure it to work. Hope this gives you an idea 
of what might be going wrong in your setup:

Situation before I start (done from another server in our serverpark):
username at mgmt-server:~$ snmpwalk -v 2c -c public 192.168.2.71 
.1.3.6.1.4.1.674.10892.1.300.10.1.11.1
Timeout: No Response from 192.168.2.71

Steps I take to install and configure snmpd:
* apt-get install snmpd
* Edit /etc/snmp/snmpd.conf
        - Comment out 'com2sec paranoid  default         public
        - Uncomment out '#com2sec readonly  default         public'
        - Change 'default' into our management IP range in the previous 
step (resulting in 'com2sec readonly  192.168.2.0/24         public')
* Edit /etc/default/snmpd
        - Change SNMPDOPTS
                - Before: SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux 
-p /var/run/snmpd.pid 127.0.0.1'
                - After: SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -p 
/var/run/snmpd.pid 0.0.0.0' (this enabled smux and made snmpd listen on 
all interfaces, instead of lo)
* /etc/init.d/dataeng enablesnmp (this should enable SNMP for both dataeng 
itself, as it adds a line to /etc/snmp/snmpd.conf)
* /etc/init.d/dataeng restart (restarts dataeng and starts dsm_sa_snmp32d)
* /etc/init.d/snmpd restart

After this, SNMP seems to be working:
username at mgmt-server:~$ snmpwalk -v 2c -c public 192.168.2.71 
.1.3.6.1.4.1.674.10892.1.300.10.1.11.1
SNMPv2-SMI::enterprises.674.10892.1.300.10.1.11.1 = STRING: "<our tag was 
here>"

RE: Getting Dell SNMP MIB to work on Debian?

Jonas, Here's what I get with both 10892 and 10893:
kevinz at centernet:~$ snmpwalk -v2c -c xxxxxxxx localhost
1.3.6.1.4.1.674.10893
SNMPv2-SMI::enterprises.674.10893 = No more variables left in this MIB
View (It is past the end of the MIB tree)
kevinz at centernet:~$ snmpwalk -v2c -c xxxxxxxx localhost
1.3.6.1.4.1.674.10892
SNMPv2-SMI::enterprises.674.10892 = No more variables left in this MIB
View (It is past the end of the MIB tree)
kevinz at centernet:~$

The query I'm using should return the Dell service tag, as it does on
the Dell PE www.jhuccp.org server:
kevinz at centernet:~$ snmpget -v2c localhost -c xxxxxxxx
.1.3.6.1.4.1.674.10892.1.300.10.1.11.1
SNMPv2-SMI::enterprises.674.10892.1.300.10.1.11.1 = No Such Object
available on this agent at this OID
kevinz at centernet:~$ snmpget -v2c www.jhuccp.org -c xxxxxxxx
.1.3.6.1.4.1.674.10892.1.300.10.1.11.1
SNMPv2-SMI::enterprises.674.10892.1.300.10.1.11.1 = STRING: "14DC491"
kevinz at centernet:~$ 

This query should return the ambient temperature in tenths of a degree
Celsius:
kevinz at centernet:~$ snmpget -v1 localhost -c xxxxxxxx
.1.3.6.1.4.1.674.10892.1.700.20.1.6.1.3
Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: SNMPv2-SMI::enterprises.674.10892.1.700.20.1.6.1.3

kevinz at centernet:~$ snmpget -v1 www.jhuccp.org -c xxxxxxxx
.1.3.6.1.4.1.674.10892.1.700.20.1.6.1.3
SNMPv2-SMI::enterprises.674.10892.1.700.20.1.6.1.3 = INTEGER: 210
kevinz at centernet:~$

Thanks for your suggestion. I welcome any ideas or thoughts.

-Kevin

            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

are you sure that this OID is correct? 

I'm using for testing omsa with snmp (on PE2950) this OID: 
snmpwalk -v2c -c xxxxxxxx localhost 1.3.6.1.4.1.674.10893

Greets,
                 Jonas
