Error When Reading From Ssl Socket Connection Avocent
SSL Socket Connection Error Posted on August 14, 2015 10:41 pm by Phillip Jones Comment Issue: Error message "Error when reading from SSL socket connection" when launching Remote console on a Dell DRAC server using the Java Plug-in Type. I have always had a love/hate relationship with Java (You got me, its actually just hate, no love). There are a lot of Java configurations required for various applications but let's get on to the actual issue. I have a Dell PowerEdge 2950 in my lab with DRAC that I sometimes use for remote console and management especially if I am working remotely trying to resolve something in my lab. I tried to use the Java Console and I get the following error message. Error Message: "Error when reading from SSL socket connection" Some lab details: Server: Dell PowerEdge 2950 Bios: 2.7.0 RAC version: DRAC 5 v1.65 Java Version 1.8.0_31 (latest installed) OS: Windows 10 Enterprise Browser: Any - tested with IE, Chrome and Firefox In doing some digging I found that it was using SSLv3 which is disabled by default in JAVA. Resolution: Open java.security file located in C:Program FilesJava%java_version%libsecurity Note %java_version% will actually be the version of Java you have installed on your machine. Such as if you have installed JRE 1.8 Update 31 you would see the following path "C:Program FilesJavajre1.8.0_31libsecurity" Comment out the following line by adding a # "jdk.tls.disabledAlgorithms=SSLv3" Voila!! Issue resolved. I can now launch the remote console using the Java Plugin. I could have switched to Native and used ActiveX plug-in type but I also don't always use Internet Explorer and broken things and work-arounds bother me… Thanks for listening, and let me know if this does not work for you. See you on the flip side!! 📂This entry was posted in 2950 Dell Drac Error Java PowerEdge SSL - - - tweet html « ESXi Customizer and Windows 10 Fix Back in the Sad
cards in our server farm. The remote access cards are a separate ethernet port that is always on, even when the server is powered off. You can connect in to this interface using your web browser to monitor the server's status and issue minimal commands, such as power on and open a remote console. Because most of our servers are based on the Dell PowerEdge 1950 and PowerEdge 2950, they are running some slightly-older cards, the Dell DRAC 5. The most important use for this is the remote console, the ability to connect and use http://p2vme.com/2015/08/dell-drac-java-console-ssl-socket-connection-error/ your system as if you were sitting right in front of it. The problem begins with Java, like usual. The remote console relies on Java and due to Dell considering the DRAC 5 to be end of life, hasn't given it a firmware update in several years. Over the past few years, many advances in security have taken place. As of the time of this post, https://nacko.net/dell-drac-5-with-java-1-8-error-when-reading-from-ssl-socket-connection/ the latest and greatest is TLS v1.2, with SSLv3 considered deprecated and insecure. The problem is that these old cards still want to use SSLv3 and do not support TLS. To top it off, the newer versions of Java are defaulted with SSLv3 disabled. Even after adding our URLs to the whitelist, we could not get the console to open because of the error "Error when reading from SSL socket connection". Fortunately, Java still offers a way to resolve these problems. First, make sure your DRAC address is added to the whitelist in your Java control panel under the "Security" tab. Next, we will manually have to edit the java.security file to enable SSLv3. On Windows 7 with Java 1.8u60, this file can be found in C:\Program Files (x86)\Java\jre1.8.0_60\lib\security\java.security. Search for the parameter "jdk.tls.disabledAlgorithms". Simply comment it out by adding a pound sign in front of it (#). Save your file and relaunch your remote access console from the DRAC 5 interface. You should be able to connect successfully! Please remember that, while this fixes your connection problem, you just told Java that it's okay to use what is considered an insecure cipher. Once y
