| As of Java version 7 onwards, the Java development team continue to make security "improvements" that inadvertently play havoc with Java embedded devices such as the web GUI's on KVMoIP and network switches.|
As such, we have put together this knowledge base article that will guide you through the process of tweaking your Java settings to work with our Dell KVMoIP appliances.
1.) The source computer/laptop connecting to our KVMoIP appliance must be Linux or Windows based, MAC is not officially supported
2.) You must have administrator/root/superuser access to the aforementioned computer/laptop above!
3.) You need an up-to-date install of the Java Runtime Environment which at the time of writing this article is Version 8 Update 66
Step 1 - Modify 'java.security' File:
4.) On a Windows device, find and open the file 'java.security' in Program Files (x86) > Java > jreX.X.X_X > lib > security > java.security (X being your Java version so may differ!
5.) On a Linux device, find and open the file 'java.security' in /etc/java-7-openjdk/security/java.security
6.) Now look for a non commented out line that begins 'jdk.tls.disabledAlgorithms' comment it out and underneath it add a new line with:
jdk.tls.disabledAlgorithms=SSLv3, EC, ECDHE, ECDH
7.) Save and exit the file
Step 2 - White List KVM IP:
8.) Please add 'http' white list entries into the 'Security' tab in your Java control panel for the following KVM IP addresses:
Step 3 - Re-launch the Java Runtime Environment
