KVM connection no longer working after upgrading to bmc-support branch

[jleroy]

First of all, thank you Kevin for your hard work on the RFB protocol. This is really appreciated. 👍

Since I've updated my noVNC setup from commit 63cc01f (lastest commit from bmc-support-old branch) to eb386b7 (latest commit from bmc-support branch), I can no longer connect to any of my servers.

I get a red banner in noVNC with the following error message: Unsupported server.

Here's the output of my browser's console (latest version of Google Chrome on macOS 10.12.3):

Here's the list of motherboard tested:

• X9SRI-F
  • BIOS Version: 3.2 / BIOS Revision: 4.6
  • BIOS Version: 3.0a / BIOS Revision: 3.0
  • BIOS Version: 3.0 / BIOS Revision: 3.0
• X9SRH-7TF
  • BIOS Version: 3.2 / BIOS Revision: 4.6
  • BIOS Version: 3.00 / BIOS Revision: 2.0
• X10SRi-F
  • BIOS Version: 2.0 / BIOS Revision: 5.6
  • BIOS Version: 1.0b / BIOS Revision: 5.6

All of these motherboard worked with the bmc-support-old branch, none works with the bmc-support branch.

I second this -- bmc-support-old works (63cc01f), bmc-support doesn't (eb386b7) -- on:

• X9DRi-LN4F+
  • BMC firmware version 3.48
