Script Configuration

The script needs a configuration file where it can be read by the Bacula DIR user. We suggest copying the provided example configuration to a suitable location:

# cp -a ITS-*.py /usr/local/lib/python3.9/site-packages/pysnmp/smi/mibs
# chown root. /usr/local/lib/python3.9/site-packages/pysnmp/smi/mibs/ITS-*
# chmod 644 /usr/local/lib/python3.9/site-packages/pysnmp/smi/mibs/ITS-*

  cp -iv bsnmp.conf /opt/bacula/etc/
  chown bacula. /opt/bacula/etc/bsnmp.conf

The configuration needs to be adapted. Using your favourite plain text editor, edit it:
```
[thisengine]
snmp_version = Valid values are 1, 2c or 3
username = USM user name on TRAP/INFORM receiver system
authkey = passphrase used to generate the SNPMv3 authkey
privkey = passphrase used to generate the SNPMv3 privkey

[target]
ipv4 host = DNS or IP address of trap receiver. IPv4 only
udp port = 162
```
The information to put will, naturally, be very site specific and may need to be provided by a different team/person. Note that, at this time:
- SNMPv1, SNMPv2c and SNMPv3 are supported. It is strongly recommended to use SNMPv3.
- only the USM scheme is supported (we may support more in the future, but USM still seems to be the typical case)
- only HMAC-SHA authentication and AES-CFB-128 encryption are supported. This will probably be extended in the future.
- only UDP transport is supported. This should not be a problem. The port number is optional, default is 162, which is the assigned port number, and thus should not need modification in most cases.
