iDRAC6: undocumented settings for console com2

Sorry, I haven't gotten back to you.  A hernia operation has left me flat on my back (literally).

The topology can be much simpler and still fail.  For example

A-sysadm desktop <-----> B=iDRAC6 

If A runs a vncviewer (either locally or on B's machine) and brings up a browser in the vncviewer, points the browser to B's iDRAC6, and launches the console, the keys will be mapped incorrectly.  Chuck Anderson ( wrote of one possible solution, but it only seems to address the arrow and sysreg keys.  With respect to the iDRAC6, all the keys appear to be mapped incorrectly when typing in any text window on the console within a VNC session.  Since the same situation work fine with the iDRAC5, I would think that this should be an issue Dell should correct.

Note that if one brings up the browser from A and points the browser to B's iDRAC6 (without using VNC), it works okay.  However, my actual situation is much more complicated which, because of network security on the gateway machine, prohibits port forwarding.

In addition to working on the iDRAC5, the VNC interface also works when using HP's iLo3.  So again, I think that this is a bug in Dell's iDRAC6 firmware.  Does anyone know the method for reporting this bug?

I did.  Our desire to use a serial console stems in part from how
cumbersome it can be to access DRACs located on a secure network --
which I expect has something to do with why you're having to use VNC.
So I guess in that sense our posts are related.

So, topology:
  A=Sysadmin's desktop  <--->  B=gateway  <--->  C=DRAC

You're using VNC for the link between "A" and "B", then running the
browser/java on "B".  So https and proprietary-applet-VNC are
connecting "B" and "C".  I don't know what OS your intermediate host
is running.  If *nix, you might check X11 keymaps and such.  Have you
tried switching the flavor of VNC software running on A and/or B?

We initiate an ssh connection to the intermediate host with port
forwarding, so that ports 443, 5900, and 5901 pass from A, through B
to C.  That is, if both A and B are *nix/Mac OS: 
  ssh gatewayhost -L 443:drac-host:443 -L 5900:drac-host:5900 -L 5901:drac-host:5901 -N
and then on my desktop, I point my browser to 

Would our approach be of use to you?
