| Use this as an example on how to start the virtual console without the need of Java Web Start or accessing it from the web interface. | |
| You can use the user and password that you use for the web interface. | |
| You need an old JRE... I used 1.7.0_80 from the Server JRE package, also I have tested successfully 1.7.0_79 with MacOS. | |
| You don't need to install it, just extract it or copy the files in "jre" folder. | |
| Open the viewer.jnlp file that you get by launching the virtual console from the web interface with a text editor. | |
| Note the urls to the jar files. Download the main jar file avctKVM.jar and the libs for your operating system and architecture. | |
| Extract the dlls (.so Linux, .jnilib MacOS) from the jar libs. | |
| If you don't see the MacOS libs in the file make sure you download it from MacOS. | |
| Edit the bat/sh file according to your needs. | |
| The file structure should look like this: | |
| start-virtual-console.bat (.sh if Linux/MacOS) | |
| avctKVM.jar | |
| jre/<jre home here> | |
| lib/avctKVMIO.dll (.so if Linux, .jnilib if MacOS) | |
| lib/avmWinLib.dll (.so if Linux, .jnilib if MacOS) |

On mac osx big sur, i couldnt manage to make it work with all the instructions properly done and java.security file patched. I downloaded and used jre1.7 as mentioned before. I commented disabledAlgorithms and left it empty, neither way worked as well. I can use the same script to connect on windows using jre1.6.
I still get the following error. Did anybody manage to solve it in big sur+ ?

And here is the command:
sudo spctl --master-disable
./jre1.7-mac/Contents/Home/bin/java -cp avctKVM.jar -Djava.library.path=./lib com.avocent.idrac.kvm.Main ip="10.0.0.100" kmport=5900 vport=5900 user=*** passwd="****" apcp=1 version=2 reconnect=2 vmprivilege=true "helpurl=https://10.0.0.100:443/help/contents.html"
Hi
I'm not on macos but could this be just working directory ambiguity with the lib directory,, i.e.
sudo spctl --master-disable
cd ./jre1.7-mac/Contents/Home
./bin/java -cp avctKVM.jar -Djava.library.path=./lib com.avocent.idrac.kvm.Main ip="10.0.0.100" kmport=5900 vport=5900 user=*** passwd="****" apcp=1 version=2 reconnect=2 vmprivilege=true "helpurl=https://10.0.0.100:443/help/contents.html"
Alternativey fully qualified lib path
sudo spctl --master-disable
./jre1.7-mac/Contents/Home/bin/java -cp avctKVM.jar -Djava.library.path=./jre1.7-mac/Contents/Home/lib com.avocent.idrac.kvm.Main ip="10.0.0.100" kmport=5900 vport=5900 user=*** passwd="****" apcp=1 version=2 reconnect=2 vmprivilege=true "helpurl=https://10.0.0.100:443/help/contents.html"
Apologies if already checked this is correct directory
@jimfrench I havent tried this yet but i ll check if it works. Though, I don't think this would be the cause because it works until tls connection phase. Thanks for the advice anyway.
@ardabeyazoglu Yes I should have explained my reasoning, it could have been using libraries from the wrong java version, but you might be correct in that it probably wouldn't get that far if so, it would error out sooner than during the connection. Hope someone else can step in good luck.
I tried many different combinations, java versions, etc., and finally discovered that iDRAC 6 is compatible with IE v8 on Win 7 SP1. I downloaded Win 7 SP1 and installed it on a virtual machine. It installs its ActiveX to IE 8 on the first run. Then I put the website on trusted sites. and voila!
:)
For those non java-savvy of us that are reading this and stumped on the Virtual Media/Keyboard capture errors above, you're missing a step;
After downloading avctKVMIOMac64.jar & avctVMMac64.jar from the iDRAC service, unzip them and move to the lib folder. Jar files are just glorified Zips, the real lib treasure is inside
unzip -d avctKVMIOMac64 avctKVMIOMac64.jar
unzip -d avctVMMac64 avctVMMac64.jar
mkdir lib
cp avctKVMIOMac64/libavctKVMIO.jnilib ./lib/
cp avctVMMac64/libavmMac.jnilib ./lib/
Thanks to https://github.com/DaveCorder/ikvm-osx for the java-for-dummies explanation.
Works for me allowing me to connect to the virtual console on my R710. Glad I no longer need to dig out a VGA monitor. Thank you!
I am getting java/lang/NoClassDefFoundError: java/lang/Object anyone else?
Does anyone have this running with the separate Java version so I do not need to modify my Java Config? Ifso can you please share the working files as the things in this thread do not seem to work properly at the time im posting this or if anyone is willing to help me diagnose the issue that is more familiar with Java that would be amazing.
I have 20 Servers we have running IDRAC6 and would like to be able to use the feature but DO NOT want to run a unsecured install of Java if we can start a portable version for this.

Hi, I'm currently using a docker container version which is maintained, and seems to work very well without having to change any java versions manually - it is a "portable version" but dockerised
I was able to connect doing this (iDRAC 6 Enterprise):
- Downloaded this file from Oracle website: server-jre-7u80-windows-x64.tar.gz (https://www.oracle.com/java/technologies/javase/javase7-archive-downloads.html#license-lightbox)
- Created a folder on my drive (C:\idrac)
- Expanded the tar file and copied all content from this directory: .\server-jre-7u80-windows-x64.tar\jdk1.7.0_80\jre\ to C:\idrac\
Here's how my directory ended:
Then I'm using this PowerShell script:
Set-Location -Path C:\idrac
$ServerHost = Read-Host "Type the name of the host that you want to connect to"
$HostPassword = Read-Host "Type the password of the host that you want to connect to"
Write-Host "nDownloading files..." wget.exe -N --no-check-certificate "https://$ServerHost/software/avctKVM.jar" -q wget.exe -N --no-check-certificate "https://$ServerHost/software/avctVMWin64.jar" -P lib -q wget.exe -N --no-check-certificate "https://$ServerHost/software/avctKVMIOWin64.jar" -P lib -q Write-Host "nExpanding files to initiate connection..."

Remove-Item .\lib*.dll
Remove-Item .\avctKVM.jarIt worked without modifying my PC java.security file.
The only problems until now is that I didn't find a way to pass the password using PowerShell in a secure way (I have tried the -AsSecureString), so for now the password is in plain text... =/ And I have tried to use this code to download the files:
Invoke-WebRequest https://$ServerHost/software/avctKVM.jar -OutFile .\avctKVM.jarBut sometimes worked, sometimes don't, I think that I need to initiate the connection first... Meanwhile I'm using wget as other users commented previously.
Anyway, thanks a lot for your time to help a lot of people!!!
JAN 29 2023 / WINDOWS 10: Took your script and made changes to get it to work on my PC.
Steps:
- Downloaded the same JRE you mentioned first from Oracle website
- Created C:\IDRAC and expanded as you suggested
- Created C:\IDRAC\idrac.ps1 file using notepad with the following contents. Notice that I exit before the last 2 remove commands. It works now, I don't have time to spruce it up.

Thank you for this!! I was able to do the same for my Linux running Debian 11.
I unzipped the two files:
avctKVMIOLinux64.jar
avctVMLinux64.jar
Then I copied the two extracted files over to jdk1.7.0_80_x64/lib folder:
libavctKVMIO.so
libavmlinux.so
Boom it worked!
I got it to work:
The tricky part was trying various platform .jar files till I found one that worked. As @greecemunky said, it was just a matter of finding the right one.
