Setting up an SELinux enabled system to receive alerts

About this task

Security-Enhanced Linux (SELinux) is a security module that authorizes or prevents operations in Linux operating systems. When

SELinux is enabled on the system running SupportAssist, alerts (SNMP traps) from remote devices are not received by

SupportAssist. Without receiving alerts, SupportAssist will not be able to identify hardware issues that may occur on remote devices.

Therefore, you must perform the following steps on the system running SupportAssist to allow SupportAssist to receive alerts from

remote devices.

NOTE: SELinux is enabled by default in the following operating systems:

• Red Hat Enterprise Linux 6 or 7

• CentOS 6 or 7

• Oracle Enterprise Linux 6 or 7

Steps

1. Open the terminal window and create a policy le named supportassistpolicy.te.

2. Open the policy le (supportassistpolicy.te) and type the following:

module supportassistpolicy 1.0;

require {

type websm_port_t;

type snmpd_t;

type root_t;

class tcp_socket name_connect;

class dir { write add_name };

class file { write getattr open create };

}

#============= snmpd_t ==============

allow snmpd_t websm_port_t:tcp_socket name_connect;

allow snmpd_t root_t:dir write;

allow snmpd_t root_t:dir add_name;

allow snmpd_t root_t:file { write create open getattr };

3. Save the policy le.

4. Browse to the folder where you saved the policy le.

5. Type checkmodule -M -m -o supportassistpolicy.mod supportassistpolicy.te and press Enter.

6. Type semodule_package -o supportassistpolicy.pp -m supportassistpolicy.mod and press Enter.

7. Type semodule -i supportassistpolicy.pp and press Enter.
