Computer powers on itself after shutdown.

I used to run into a problem in which my newly built computer would power on itself after being shutdown. Most of the online posts talked about Windows Scheduled Tasks. However, these come into play only when the computer is in 'Sleep' mode not in shutdown.

Finally, I found the solution. The problem was a default setting on Asus motherboard (Z87 Pro) which kept the Wireless adaptor powered on even though the computer was shutdown. This would cause the box to boot up anywhere between 2 and 20 mins after shutdown.

The solution was to enable "ErP Ready" under the APM Configuration in the BIOS. When the machine shuts down with the Wifi adapter enabled, the Wifi LED will go off (instead of staying on like before). The ErP mode setting will disable the Wifi wakeup at the BIOS level. The setting description says, "This item allows user to switch off some power at S5 to get the system ready for ErP requirement."

S5 state is the shutdown/OFF state. So it makes sense when it says it switches off power at the S5 state; it switches off power to the Wifi module, essentially disabling it and not allowing it to turn the machine on.

Installing a SSL on a synology DS

I assume you are running OSX or Linux and have openssl installed.

Follow the steps below to create and install the SSL

1. Open a terminal and type the following commands. The first command will ask for a paraphrase. The same paraphrase will be required by the other commands.

• openssl genrsa -des3 -out my.key 2048
• openssl rsa -in my.key -out final.key
• openssl req -nodes -new -key my.key -out request.csr
• openssl x509 -req -in request.csr -signkey my.key -out certificate.crt -days 3650

2. The above commands will create the key and the certificate. They will be stored in my.key and certificate.crt respectively.

3. Login to the DSM GUI, go to the control panel, DSM Settings, HTTP Service and click the button marked Import Certificate.

4. For the private key select my.key and for the certificate select certificate.crt. Reboot the NAS.

Disable notifications for a service in nagios

Assuming you are running nagios on a UBuntu box and want to disable notification emails for a particular service, you would follow the steps below.

1. Locate the service configuration file. In my case it happened to be located at /etc/nagios3/conf.d/localhost_nagios2.cfg

2. Edit the file and find the service definition for the service you are interested in. The service definitions all start with 'define service'

3. Add the following configuration inside the service definition

notifications_enabled 0

4. Restart nagios - /etc/init.d/nagios3 restart

Notification would now be disabled for this service.
