Cisco UCS Manager and Java 8 - can't connect to a server console

Evgeniy Lotosh

Recently I updated Java on my Windows 8 PC from v7 to v8. After that I discovered that I was unable to connect anymore to Cisco UCS Manager due to security reasons (the certificate is not trusted, we can't let you connect to that extremely dangerous site, and even don't ask for it... I hate Java!) I managed to add the IP addresses of Cisco USC Manager and all blade servers management processors to the safe address list (both HTTP and HTTPS), so now I can connect to the USC Manager itself. However, I still can't connect to KVM consoles of blade servers. The console application starts, then says that it's connecting to the server, then just displays the message "Connection failed". That's all.

 

In the same time I still can connect to a KVM console from another server running Java 7 and Windows Server 2012 RTM.

 

Is there any way to connect to a server console using Java 8? I'd prefer not to downgrade Java to v7 as it would start complaining again that it's obsolete and must be upgraded. Among other things, it makes more difficult working with other Java-based applications.

 

Our 6248UP interconnects and B200 M3 servers run firmware 2.2(1d).

I think I fixed this by removing 3DES_EDE_CBC from jdk.tls.disabledAlgorithms in lib/security/java.security (in the JRE directory)
