### Configure TLS with PSK

Edit the zabbix configuration file:

```
sudo nano /etc/zabbix/zabbix_agentd.conf
```

Set the following parameters where **unique\_psk\_identity** is some unique value for the agent you are configuring. I can be anything as long as it's unique for this host:

```
TLSConnect=psk
TLSAccept=psk
TLSPSKIdentity=unique_psk_identity
TLSPSKFile=/etc/zabbix/zabbix_agentd.psk
```

save the file and close

Run the following command to generate a psk file using the path and name specified in the **TLSPSKFile** parameter from above:

```
openssl rand -hex 32 | sudo tee /etc/zabbix/zabbix_agentd.psk
```

Note the generated random string as you will need it to configure the agent on the Zabbix server under the **Configuration --> Hosts --> Host -->Encryption** tab.

```
sudo systemctl start zabbix-agent
sudo systemctl stop zabbix-agent 
sudo systemctl status zabbix-agent
