getting permission denied error while using NET-SNMP-EXTEND-MIB

Question

Hi Guys,

I have created two shell scripts to monitor file size of two files and want to run using NET-SNMP-EXTEND-MIB kept in /bin folder.

a) /bin/etcodbc.sh

#!/bin/sh

ls -l /etc/odbcinst.ini | awk '{ print $5}'

Script a is working fine using NET-SNMP-EXTEND in UnDP poller and giving proper output.

b)/bin/rootodbc.sh

#!/bin/sh

ls -al /root/.odbc.ini | awk '{ print $5}'

added below lines into snmpd.conf

exec rootodbc /bin/sh /bin/rootodbc.sh

exec etcodbc /bin/sh /bin/etcodbc.sh

while running snmp translate command getting OID as well. But in UnDP getting permission denied error.

Can any one help me solve this.

Finally, I got the solution. I allowed snmpd_t context in selinux and got success.For this "policycoreutils-python" package should be installed on server.

1. Install below package for

yum install policycoreutils-python -y

2. Allow snmpd in selinux policy

semanage permissive -a snmpd_t
