SSH into GRUB2

SSH into GRUB2

[DebBug]

[-- Attachment #1: Type: text/plain, Size: 480 bytes --]

Hello grub-devel,

Is there any support for or are there any 
intentions to support SSHing into GRUB2?

I realize this would require a network stack 
to be integrated. Is this feasible with 
reasonable effort? Would it be accepted at all?

The idea behind this is to be able to SSH into GRUB, 
having remote unlock capability for true Full Disk 
Encryption where /boot is equally encrypted.

Thanks for your input. Evaluations welcome ;-)

Happy holidays!

Nils

grub2 already contains a complete and working TCP/IP stack. The only 
thing which may be missing is a card driver for the environment it is 
running on.

I once wrote a card driver for the Xen virtual network card and a Telnet 
implementation, just to educate myself. It is not perfect (nor secure), 
but it works. So it should not be impossible to implement ssh support.

Hello Manfred,

Thank you for your quick reply.

That's good news.

Any chance you could provide your code for reference?

Happy holidays,

Nils
