If the OP has a BMC/ILO in his server, he could set the next boot device to
a PXE server he controls.  Then issue a reboot via serial over LAN and it
can boot whatever live Linux image (benefit being SSH is available) and
shred from there.  DBAN is nice as it is/can be automated, but it may not
be a suitable solution for this situation.  The OP will not have any SSH
access with DBAN nor access to the console (I'm thinking serial over LAN)
because DBAN does not likely output to a serial port.

To the best of my knowledge DBAN has not had SSH support added.  The
original/primary developer no longer works on the project.
