SuperMicro

For the public cloud "Betacloud" we use hardware from SuperMicro. Therefore there is this chapter with hints about SuperMicro.

Copy & paste in the iKVM remote console

MacOS

Bind the following command to a hot key, for example with BetterTouchTool (https://folivora.ai). Copy the text you want to paste into the clipboard. Then press the hot key in the opened iKVM console.

osascript -e 'tell application "System Events" to keystroke the clipboard as text'

Reset IPMI password

$ apt-get install ipmitool
$ ipmitool user list
$ ipmitool user set password 2 ADMIN

Configure and mount Samba share

Samba service

Virtual Media

Application Blocked by Java Security

In older Supermicro systems, Java is still used for the virtual console.

When calling the virtual console via the Java WS file you get the error Application Blocked by Java Security.

In the Java control panel, an exception can be added to the Exception Site List (under Security) (https://techhelpkb.com/why-do-i-see-application-blocked-by-security-settings/).

Then execute the Java WS file again. There is now another safety instruction, which can easily be confirmed.

Use of old Java iKVM Viewer with current JRE version

In older Supermicro systems, Java is still used for the virtual console.

If the Java iKVM Viewer does not work correctly this is probably due to disabled SSLv3 support.

SSLv3 can be enabled in the java.security file.

The file can be found in the lib/security directory of the active JRE installation. On a MacOS e.g. /Library/Java/JavaVirtualMachines/jdk1.8.0_74.jdk/Contents/Home/jre/lib/security. The version of the used JRE can be obtained by calling java -version.

#jdk.tls.disabledAlgorithms=SSLv3, RC4, MD5withRSA, DH keySize < 768
jdk.tls.disabledAlgorithms=RC4, MD5withRSA, DH keySize < 768
You can’t perform that action at this time.
