#Debian #Squeeze does not install #SNMP #MIBs. Example error message:

# snmpget -Os -c public -v 1 <host> system.0

system.0: Unknown Object Identifier (Sub-id not found: (top) -> system)

Fix: Insert non-free into /etc/apt/sources.list:

deb http://ftp.de.debian.org/debian/ squeeze non-free

... and install snmp-mibs-downloader:

# apt-get update && apt-get install snmp-mibs-downloader
