Question

How do I enable java applets.

Hi,

I need to adminster a number of virtual machines hosted on a FreeNas system and accessed through a phpVirtualBox interface.

To access the console of the virtual machines a Java based VNC Viewer applet is launched. As soon as this happens my MacBook blocks the execution.

I have attempted to add the site to the list of safe sites, but as this is my home and accessed via a dynamic DNS redirection system, and I do not have an SSL Certificate I am not permitted to trust machines my own home.

I work abroad, I am not physically in the same building as the FreeNas server.

The machine is a mid 2012 Macbook Pro and has been factory reset and reinstalled with Sierra last night.

How should I approach this task?

MacBook Pro (Retina, Mid 2012), iOS 10.1.1, null

It is possible that you are running into this issue from https://www.java.com/en/download/help/java_blocked.xml

"Java has further enhanced security to make the user system less vulnerable to external exploits. Starting with Java 7 Update 51, Java does not allow users to run applications that are not signed (unsigned), self-signed (not signed by trusted authority) or that are missing permission attributes."

Your error is discussed at the above linked to site. And once again I think you might want to visit the phpVirtualBox site. This appears to be a case of an app issue.

Cool thanks, I will investigate this exception site list that link talks about, think I might be getting closer!

So this is nothing to do with apple and all to do with Java then?

FWIW, bumping your post an hour later isn't going to get you an answer any sooner. You just have to wait until someone who may have an answer responds. However, your question doesn't seem to be Mac or OSX specific, but more how to get a phpVirtualBox interface to work. You might want to post your question on the VirtualBox forums.

phpVirtualBox is a web front end to access a virtual box. When is your problem sowing up? If it is in your browser I suspect you have not allowed javascript in the browser.

Your best source of assistance will be as already suggested by dialabrain.

Thanks I will try this as soon as I get back to the hotel and let you know. There are no third party apps on the machine except firefox which I installed to see if it was a safari issue or a macOS issue. I concluded MacOS because changing to the firefox browser made no difference.

You didn't originally say you are trying to access from a hotel. It is common for hotel and other similar access point to restrict access to other than common ports and protocols. It is very possible that the hotel is blocking the necessary port or protocol.

Hey,

ok so I am perfectly able to get into the website on the right ports, these are the browser settings relating to javascript and below is the error message once I attempt to view the remote virtual machine console.

So, I really don't care about these security settings, this is a freshly installed operating system, the website is hosted in my own home and I trust the application developers of the FreeNAS software and VNC Viewer completely.

How do I override the security settings in macOS Sierra and tell it to run this application regardless of what it thinks is a good idea?

Thanks for your replies.

The problem occurs as soon as I click on the "console" button in either safari or Firefox. A warning appears saying that the application is blocked by security settings.

Disable the security settings in the browser. Enable allow javascript. Or, you have installed a third party app that claims to protect your computer. Uninstall this app.

I want to say "Thats cracked it", I still have issues but they are nothing to do with the OS and more to do with navigating the IP and port forwarding I have set up.

Thanks a lot for your help!
