Hello guys , I was trying to get a command output from my Centos 6 server using the snmpd "exec" section. The line added to snmpd.conf id: exec get_whitelist /bin/cat /home/snmp_user/whitelist.txt Afer trying to get the resut performing the snmpwalk client form another server I always got "permission denied" After reading some forums I founded that disabling selinux It works. My question is .. What is the proper way to achieve snmpd executing some commands ? In my case it is working now but ... Im not sure if disabling selinux is the best way. Regards. Leandro.
