Access the file manager on webmin

Question

Today, when I try to open the file manager on my webmin page, it shows me the error that your security settings have blocked an untrusted application from running.

I updated the java but I am getting the same error.

Please help me to find the solution.

Thanks.

Solution 1

Due to a change of the Java Runtime version 7u51 on loading the file manager an error displays, that the application is blocked by security settings. This can be avoided by adding the address of the Webmin to the Exception Site List in Java Control Panel.

Please proceed as follows:

Open the Java Control Panel in Systems|Java. Select the tab "Security". Click the "Edit Site List..." button. Click the "Add" button in the "Exception Site List" dialog. Enter the address of Webmin, e.g. „http://licensecentral.company.local:10000“. Click the "OK" button. Click the "Continue" button to accept the security warning. Click the "OK" button to close "Java Control Panel".

By default the latest versions seem to block the Webmin Java modules, usually because there is some problem with the certificate. You can change the security settings or, much much better, add the server(s) you manage with Webmin to the site exception list using the Java security settings in the Java control panel. On a home server just add https:// followed by the site ip addresss. For me it seems to work if you tack on the :10000 for the Webmin port at the end. You will still get all sorts of dire warnings of the impending apocalypse when you access the modules, but at least they will work.

Chrome 42 has disabled java feature by default now.

For now you can just go to the url below in chrome and enable the npapi and relaunch.

chrome://flags/#enable-npapi

Come September 2015, that option will disappear permanently.

I found Chrome Version 42.0.2311.90 m still shows the "plugin not supported" message even after trying all of the above suggestions. I did find however if I clicked on this link http://www.java.com/en/download/installed.jsp I was able to allow the security prompts again and then noticed with Alauddin's tip you have to click the "restart" button at the very bottom right hand corner after enabling

chrome://flags/#enable-npapi

The browser closed and restored with all my open tabs and the java app was working again after confirming a prompt.
