| 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!
Step 1 - Modify 'java.security' File:
3.) 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!)
4.) On a Linux device, find and open the file 'java.security' in /etc/java-X-openjdk/security/java.security (X being your Java version so may differ!)
5.) Now look for a non commented out line that begins 'jdk.tls.disabledAlgorithms' - comment it out and underneath it add the following line:
jdk.tls.disabledAlgorithms=SSLv3, EC, ECDHE, ECDH
6.) Similarly, look for a non commented out line that begins 'jdk.jar.disabledAlgorithms' - comment it out and underneath it add the following line:
jdk.jar.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
