 Posted: Tue Sep 11, 2018 7:39 am Post subject: Genkernel SSH option explained. |
 |
|
I've installed the initramfs with the ssh (dropbear) option, but I'm still lost as far as the implementation goes. This is what I have figured out, so far, from going through /usr/share/genkernel/default/login-remote.sh and initrd.scripts...
* I start the box in questions.
* From the remote system, I transmit the LUKS key (ref:login-remote.sh:114-123):
| Code: |
$ dd if=fortknox.key | ssh -o UserKnownHostsFile=/tmp/tmpknownhost root@fortknox.example.org -- post root
1+0 records in
1+0 records out
512 bytes copied, 5.9631e-05 s, 8.6 MB/s
|
* Then I bump it to get it unlocked (ref: login-remote.sh:124-127):
| Code: |
$ ssh -o UserKnownHostsFile=/tmp/tmpknownhost root@fortknox.example.org
rmdir: 'tmp': Directory not empty
Connection to fortknox.example.org closed.
|
Yet, the box still remains held up at:
| Quote: | | Enter passphrase for /dev/vda3: |
I know that it has unlocked the luks volume, as evident in busybox, but it doesn't free up the local cryptsetup request.
Any ideas? Is there a how-to/wiki page as far as incorporating SSH Dropbear with a genkernel generated initramfs? |

Hi,
I also ran into a similar issue. As you noticed, the current script doesn't work (cryptsetup keeps running and blocks the boot process). I've submitted a PR here which will hopefully be merged and fix this: https://github.com/gentoo/genkernel/pull/8 |
