So the VMWare uses dropbear ssh in their ESXi 3.5 product, problem is
there is a bug in it where the return status is always 255, regardless of
the commands return status. I'm trying to set up with ESX localdisk, Did I
miss something important here related to the setup of ssh for ESXi 3.5? A
quick google search shows that this is a know bug in dropbear, and has been
patched in recent versions, but vmware does not have an updated version that
I can find. Is there a known work-around?

 example:

[r...@vcl VCL]# /usr/bin/ssh -l root -p 22 -x 192.168.28.2 "echo yeah &&
echo $?"
yeah
0
[r...@vcl VCL]# echo $?
255

So this time with -vv:

[r...@vcl VCL]# /usr/bin/ssh -vv -l root -p 22 -x 192.168.28.2 "echo yeah &&
echo $?"
