How to Suppress SNMP UDP connections from syslog

what is the debug file for SNMP ?

for 5.x Linux servers its :- /etc/sysconfig/snmpd.options
For 6x :-   /etc/sysconfig/snmpd

Below you can see default debug file for 6x Linux servers.

[root@linuxtechnotes ~]# cat /etc/sysconfig/snmpd
# snmpd command line options
# OPTIONS="-LS0-6d -Lf /dev/null -p /var/run/snmpd.pid"
[root@linuxtechnotes ~]#


Incase if you notice lot of udp connection in syslog and if you want to suppress, try to change the debug level to 5 and restart the snmpd deamon.


[root@linuxtechnotes ~]# cat /etc/sysconfig/snmpd
# snmpd command line options
OPTIONS="-LS0-5d -Lf /dev/null -p /var/run/snmpd.pid"
[root@linuxtechnotes ~]#
[root@linuxtechnotes ~]# service snmpd restart
Stopping snmpd:                                            [  OK  ]
Starting snmpd:                                            [  OK  ]
