The needed Debian and Ubuntu packages are snmpd and snmp (tiny-snmpd does not work for some reason).
The following readonly “com2sec” mapping is recommended (in /etc/snmp/snmpd.conf), just uncomment as follows:
# sec.name source community #com2sec paranoid default public com2sec readonly default public #com2sec readwrite default private
Additionally, the following line needs to be present in /etc/snmp/snmpd.conf in order to establish the interface between snmpd and BalanceNG:
pass .220.127.116.11.4.1.2771.1 /sbin/bng
Note: There’s no need to change /etc/default/snmpd anymore with 2.226 and above (snmpd runs now as user snmp).
A typical “snmpget” command line looks like this:
snmpget -v1 -c public localhost .18.104.22.168.4.1.2771.1.1
A complete “snmpwalk” of the BalanceNG 2.x MIB can be invoked like this:
snmpwalk -v1 -c public localhost .22.214.171.124.4.1.2771.1
The BALANCENG-MIB may be copied to the /usr/share/snmp/mibs directory (for Ubuntu/Debian Linux). The following environment variable setting makes all MIBs in this directory available to the snmpd tools:
Note the difference between the two “snmpget” invocations below:
$ snmpget -v1 -c public localhost .126.96.36.199.4.1.2771.1.1 SNMPv2-SMI::enterprises.2771.1.1 = STRING: "2.228" $ export MIBS=ALL $ snmpget -v1 -c public localhost .188.8.131.52.4.1.2771.1.1 BALANCENG-MIB::Release = STRING: "2.228"
You may also setup a local snmp.conf like this to make this setting permanent:
$ mkdir -p $HOME/.snmp $ echo "mibs ALL" >> $HOME/.snmp/snmp.conf
