# Add the following line to /etc/rc.conf to enable snmpd:
#
# snmpd_enable="YES"
# snmpd_flags="<set as needed>"
# snmpd_conffile="<set as needed>"
#
# Add the following line to make snmpd run as root. By default it drops
# privileges after initialization, but some configurations may require
# root privileges. In particular, extension scripts may need to be run as root.

# snmpd_sugid="NO"
#
# To troubleshoot permission errors, it may be useful to run snmpd with the
# following option in rc.conf:
#
# snmpd_prepend="ktrace -i -f /tmp/snmpd_ktrace.out"
#
# The resulting trace can be inspected with "kdump -f /tmp/snmpd_ktrace.out".
