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. Prerequisites: 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: 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 37.26.104.180 37.26.104.181 37.26.104.182 37.26.104.183 37.26.104.184 37.26.104.185 37.26.104.186 37.26.104.187 37.26.104.188 37.26.104.189 37.26.104.190 37.26.104.191 37.26.104.192 Step 3 - Re-launch the Java Runtime Environment | ||
