Hi,

Is there recommended way of setting up custom SNMP (net-snmp) scripts used for monitoring the status of software or hardware RAID, Web site hits, etc.? I created a special directory for them - /usr/local/snmp/bin/, and then let sealert and audit2allow tell me what to do. My snmpScripts.te on a server with software RAID looks like this:

I would probably label /usr/local/snmp/bin/ and anything below type bin_t. This will atleast stop snmpd_t from executing generic usr files.

Example;

semanage fcontext -a -t bin_t "/usr/local/snmp/bin(/.*)?" restorecon -R -v /usr/local/snmp/bin

Besides that i guess you would need to allow snmpd_t to read /proc/mdstat files but you can use audit2allow for that as you did below.

Thanks, I like it. My snmpScripts.te looks simpler now:

module snmpScripts 1.0;

require { type snmpd_t; type proc_mdstat_t; class file { read ioctl open getattr }; }

#============= snmpd_t ============== allow snmpd_t proc_mdstat_t:file { read ioctl open getattr };

I notice that I failed to include all of my previous snmpScripts.te. Two allow lines at the bottom were missing - one for usr_t as you mentioned above and the one shown here for proc_mdstat_t.
