I'm trying to configure a DiskStation to use SNMP. I get following error when performing munin-node-configure on my ubuntu system:
root@server:/# munin-node-configure --snmp 10.0.0.2 --snmpversion 3 --snmpusername munin --snmpauthpass (something) --shell --debug
...
# Dropping host '10.0.0.2': SNMPv3 support is unavailable (Required module Crypt/DES.pm not found)
