解决SNMP服务日志错误--“transport socket”

一般这种问题出现在操作系统版本不一致，或者不同种类的操作系统，在做snmp服务监控时，大家尽量选取相同的snmp服务版本！！！

The net-snmp in Red Hat Enterprise Linux 4.5 generates the following messages. This causes flooding of /var/log/messages.

Dec 2 14:05:08 host34 snmpd[14612]: Connection from - 127.0.0.1 Dec 2 14:05:08 host34 snmpd[14612]: transport socket = 12 Dec 2 14:05:08 host34 snmpd[14612]: Connection from - 127.0.0.1 Dec 2 14:05:08 host34 snmpd[14612]: transport socket = 12 

To solve this issue, add the following options to the file /etc/sysconfig/snmpd.options:

OPTIONS="-LS 5 d -Lf /dev/null -p /var/run/snmpd.pid -a" 

Restart snmpd service. Test with an snmp query, For example, the following will test this:

snmpwalk -v 1 -c public localhost 

There should not be excessive logging of snmpd in /var/log/messages from this command.
