What is “[SNMP] DoS detected” system log message?
This message will be generated when over 300 packets per second are received by the SNMP service.
If you want to change this behaviour, there are 2 configurable fields in the [SNMP] section of uLinux.conf:
EnableDetectDDoS
MaxPacketPerSecond
The default value of EnableDetectDDoS is TRUE.
The default value of MaxPacketPerSecond is 300.
If you want to disable the DoS detection, then run the below command:
# setcfg SNMP EnableDetectDDoS FALSE
If you want to increase the maximum number of packets, then run the below command (XXX is the maximum packets per second):
# setcfg SNMP MaxPacketPerSecond XXX
Remember to restart SNMP after changing these settings.
# /etc/init.d/snmp restart
