Loading MIB Definitions - Help me get out of SNMP Hell!

Problem solved.  NANOG is awesome!  Thanks much to all who assisted.

It is actually quite easy to load the MIB definitions to you Ubuntu machine.
 I just downloaded the complete Cisco MIB tree to make life easier "
ftp://ftp.cisco.com/pub/mibs/v2".  Downloaded the "v2.tar.gz file".
 Unpacked the MIB(s) into '$HOME/.snmp/mibs' directory and life is good.
 Note that when the tarball unpacks it creates a weird directory structure.
 Just find the .my files and move them to $HOME/.snmp/mibs.

Here is success:

*jozo at crdtools:~/.snmp$ snmpget -v 1 -c 'ptasa2etb' 192.168.10.2
CISCO-PROCESS-MIB::cpmCPUTotal5min.1*
*CISCO-PROCESS-MIB::cpmCPUTotal5min.1 = Gauge32: 0*

Now that my servers understand the MIB I can get the numerical OID for
Cacti:

*jozo at crdtools:~/.snmp$ snmptranslate -On
CISCO-PROCESS-MIB::cpmCPUTotal5min.1*
*.1.3.6.1.4.1.9.9.109.1.1.1.1.5.1*

Hope this helps someone down the road.

Cheers,

Joe
