Problem accessing Values in SWRAID-MIB (Error in packet)

Hello,

I have problems accessing specific OIDs in a MIB i loaded (SWRAID-MIB).

The MIB is :
  SWRAID-MIB (the one from 
http://www.net-snmp.org/wiki/index.php/Net-snmp_extensions listed as 
dlmod module)

My Configuration is :
  Opensuse 11
  Kernel 2.6.25.5-1
  net-snmp 5.4.1-77.2

I followed the installation Instructions for the MIB which includes :
  -> compiling and installing the .so file with the according 
SW-RAID.txt file in /usr/share/snmp/mibs (that's the place for opensuse 11)
  -> edited the snmpd.conf with "dlmod swRaidMIB 
/usr/lib/snmp/dlmod/swRaidPlugin.so"
  -> started snmpd with following cmd line option "-m+SWRAID-MIB"

The Problem :
  a query like :
  snmpwalk -v1 -c public -m+SWRAID-MIB localhost swRaidMIB
  does succeed, so far so good.

  But when I query the server with snmpget (or snmptranslate) to only 
get one value by the MIBs OID !!! -  i get an error - that there is no 
such variable name in this MIB.
  Then again this only happens if I haven't recently queried the server 
before on the SW Raid MIB with Snmpwalk.
  If i did so, the snmpget requests works ...

  It seems to me, that snmpwalk somehow initializes the values for my 
MIB when walking over it, so that after an snmpwalk query i can do an 
individual request on the MIB OIDs. Here is what it looks like when I do 
some queries :

-----------------------------------
linux-6m2a:/usr/share/snmp/mibs # snmpget -v1 -c public 192.168.0.211 
.1.3.6.1.4.1.2021.13.18.1.1.3.1
Connection from UDP: [192.168.0.211]:39088
Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: UCD-SNMP-MIB::ucdExperimental.18.1.1.3.1

linux-6m2a:/usr/share/snmp/mibs # snmpwalk -v1 -c public 192.168.0.211 
.1.3.6.1.4.1.2021.13.18.1.1.3.1
Connection from UDP: [192.168.0.211]:35280
Connection from UDP: [192.168.0.211]:35280
UCD-SNMP-MIB::ucdExperimental.18.1.1.3.1 = STRING: "raid5"

linux-6m2a:/usr/share/snmp/mibs # snmpget -v1 -c public 192.168.0.211 
.1.3.6.1.4.1.2021.13.18.1.1.3.1
Connection from UDP: [192.168.0.211]:58333
UCD-SNMP-MIB::ucdExperimental.18.1.1.3.1 = STRING: "raid5"
-----------------------------------
The "Connection from" stuff is from the snmpd which i started with 
logging in foreground ....


"snmpget -Dparse-mibs" gives me
-----------------------------------
parse-mibs:   Module 16 SNMP-PROXY-MIB is in 
/usr/share/snmp/mibs/SNMP-PROXY-MIB.txt
parse-mibs: Checking file: /usr/share/snmp/mibs/SWRAID-MIB.txt...
-----------------------------------
so I suppose the MIB gets correctly loaded by snmpd ?

"snmpd -H" says dlmod support is compiled in in my suse package


Probably I misconfigured or misunderstood something ... ?

Any help would be appreciated.

Thanks Marco
