rfb.js: Support Supermicro SSG-6028R-E1CR12L

[LAKostis]

This seen on Supermicro SSG-6028R-E1CR12L (mb Super X10DRH-iT):

Firmware Revision : 3.40
Firmware Tag : BL_SUPERMICRO_X7SB3_2016-07-15_B
Build Time : 07/15/2016
Kernel Version : 2.6.28.9
Manufacturer ID : 47488
Manufacturer Name : Unknown (0xB980)
Product ID : 2137 (0x859)
Product Name : Unknown (0x859)

Apparently it's RFB v3.8 but iKVM sends 055.008 as version string and
expect the same version on client.

Thank you for the contribution!

I know exactly how frustrating dealing with the protocol negotiation oddities of the ATEN iKVMs can be, but I think that it might be better to revise your comments to indicate that this is a workaround for X7SB3 boards.

Once that's squared away, I'll be more than happy to take your pull request!

Hello,

In fact, it's not X7SB3 board, I think this name used by fw UI for internal references. Moreover, if you check official site SuperServer SSG-6028R-E1CR12L has X10DRH-iT board inside but X10DRH-iT itself works just fine with noVNC/bmc-support and official fw v3.40 (they send standard 003.008 version string). So maybe we have device with custom firmware, I'll check this tomorrow and decide how to call this board )

Okay, here the results:

• All those changes in RFB protocol version are introduced in v3.40 IPMI update for X10DRH-iT, just checked another box with dedicated board it has the same issue:

I'm seeing the 055.008 version on a X11SSE-F board as well. More interestingly, port 5900 now runs SSL, so you have to use websockify's --tls-client mode.

[kelleyk]

Very interesting. I'll see if I can find a moment to take a look; if anyone else is having the same trouble, please chime in!

Unfortunately, I don't have any X11 / E3v5 hardware to test with. I'll have to update one of my X10 boards and see if I can reproduce the issue.
