DRAC

Dell DRAC is very bad remote KVM which doesn't age well at all. Only way I found which works to have keyboard work is to use Windows XP for iDRAC7 on PowerEdge R720 which is just junk.

There is very nice fix for keyboard problems on Linux at

https://github.com/anchor/idrac-kvm-keyboard-fix

which doesn't work for me but might be worth exploring.

To make it work at all on Linux I did:

apt install icedtea-netx

Modified /etc/java-11-openjdk/security/java.security to remove everything which disables old and broken cipers which are required for DRAC 7 to work
