Package: snmpd
Version: 5.7.3+dfsg-5+deb10u2
When starting snmpd on a non-systemd machine the init script
/etc/init.d/snmpd
fails to source the file
/etc/default/snmpd
which results in SNMPDOPTS specified in the default file
being ignored:
% grep ^SNMPDOPTS /etc/default/snmpd
SNMPDOPTS='-Lf /dev/null -u Debian-snmp -g Debian-snmp -I
-smux,mteTrigger,mteTriggerConf -p /run/snmpd.pid'
% service snmpd restart
[ ok ] Restarting SNMP Services: snmpd.
% ps auxf|grep snmpd

/usr/sbin/snmpd -Lsd -Lf /dev/null -u Debian-snmp -g Debian-snmp -I
-smux mteTrigger mteTriggerConf -p /run/snmpd.pid
Please note the parameter "-Lsd" to snmpd in the process list
which is not present in SNMPDOPTS in /etc/default/snmpd.
Snippet from the init script:
DEFAULT_SNMPDOPTS="-Lsd -Lf /dev/null -u Debian-snmp -g Debian-snmp -I
-smux,mteTrigger,mteTriggerConf"
[ -z "$SNMPDOPTS" ] && SNMPDOPTS=$DEFAULT_SNMPDOPTS
It checks $SNMPDOPTS which isn't defined because the defaults file
wasn't sourced.
The init script from snmpd from stretch has these lines:
# Reads config file (will override defaults above)
[ -r /etc/default/snmpd ] && . /etc/default/snmpd
After updating snmpd from stretch to buster the default file is being
ignored.
This affects
buster (oldstable) snmpd-5.7.3+dfsg-5+deb10u2
bullseye (stable) snmpd-5.9+dfsg-3+b1
