Starting with Java version 7 and beyond,The Java development team continues to make security "improvements" that unintentionally cause havoc with Java
embedded devices such as web GUIs on KVMoIP and network switches.
As a result, we've created this knowledge base article to walk you through the process of fine-tuning your Java settings to make them compatible with our
Dell KVMoIP appliances.
Requirements:
1.) The device or laptop that connects to our KVMoIP appliance must be based on Linux or Windows,MAC is not officially supported.
2.) You must have administrator, root, or superuser access to the computer/laptop in question!
First Step: Modify the 'java.security' file
3.) On a Windows system, search for and open the file 'java.security' in Program Files (x86) > Java > jreX.X.X X > lib > security > java.security (X denotes
your Java version, which may vary!)
4.) On a Linux system, search and open the file 'java.security' in/etc/java-X-openjdk/security/java.security (X denotes the Java version, which may vary!)
5.) Find a non-commented out line that starts with 'jdk.tls.disabledAlgorithms', comment it out, and add the following line underneath it:
jdk.tls.disabledAlgorithms=SSLv3, EC, ECDHE, ECDH
6.) Similarly, look for a line that starts with 'jdk.jar.disabledAlgorithms' that isn't commented out - comment it out and add the following code underneath it.
jdk.jar.disabledAlgorithms=SSLv3, EC, ECDHE, ECDH
7.) Exit the file after saving.
Second Step: White List KVM IP:
8- For the following KVM IP addresses, please add 'http' white list entries to the 'Security' tab in your Java control panel
37.26.104.1
37.26.104.2
37.26.104.3
37.26.104.4
37.26.104.5
37.26.104.6
37.26.104.7
37.26.104.8
37.26.104.9
37.26.104.10
37.26.105.205
Third Step: Restart the Java Runtime Environment .
