If you have a domain name associated with the restaurant location, you will not be able to<br />

reference the POS system using that name without an error from your browser. The reason is<br />

that the system is reporting as xxx.penguinpos.com and you may be surfing to it as<br />

bgr123.mycompany.com. Since “mycompany.com” doesn’t match <strong>SICOM</strong>’s certificate, it will alert<br />

you.<br />

In that case, you would want to reference the system as:<br />

bgr123.mycompany.com bgr123.penguinpos.com<br />

This is especially important if the restaurant location is using a Dynamic DNS (DYNDNS) service<br />

instead of a fixed ip address. The entry in the hosts file will permit mapping from an accepted<br />

name for the certificate to the DYNDNS name that will ultimately find the restaurant.<br />

You will now want to connect to https://manager.penguinpos.com (or whatever entry you created<br />

in your hosts file). However, you will get the following message because there is one more step<br />

that is needed:<br />

You have entered the correct address, but your browser doesn’t trust the security certificate. If<br />

you have Internet Explorer 7, you can continue to the site (although IE actually recommends<br />

closing the browser).<br />

If you do, the address bar on your browser will have a red highlight and indicate a certificate error<br />

as shown below:<br />
