    @kratkale I want to fully understand:

    this is after a fresh install/fresh update from the installer and your’e having all these issues?

    it seems (at least at first glance) ftp isn’t liked very much.

    As for the snapins I’m at a loss. If you’d be daring can you install the branch working-1.6?

    This shifts from FTP in preference of actual SSH and might be better. Of course working-1.6 is more or less in “beta” so this is understandable to be hesitant, but at the same time, without enough testing and feedback, little can move the needle closer and closer to RC -> Master.

    Even in the age of AI, there’s not enough data (for me at least) to feel comfortable moving it toward master/stable yet so if you’re daring please upgrade to working-1.6

    I will highly recommend making a backup or snapshot pre-upgrade to it just in case something is significantly worse.

    The error message you got (OOPS: cannot change directory) seems to indicate authentication is now working but ftp is failing because it cannot drop you to the users’ home directory. The why of that I do not know but I do believe this would be fixed in working-1.6 (or at least I’ll have more assistance to troubleshoot things with you as I’m generally working from that branch).

    @Tom-Elliott I really appreciate that you are putting effort into providing more frequent releases, which makes it easier for everyone to deploy new security fixes in time. Keep up the good work!

    @Florent Hi Florent,

    I actually have been meaning to look into this some more, but the likely answer is no, or at least, not entirely. The way that support works is, you download a signed iPXE 2.0 binary from iPXE and a copy of their signed shim. That shim is signed with the Microsoft keys and trusts the iPXE signing keys. What this means in practical terms is, all the steps above would still need to occur, it’s just that the signing of the iPXE binary is managed by iPXE, and you don’t need to enroll a key to boot iPXE.

    That said, I would imagine this only covers you for booting iPXE, any chainloaded binaries would still need to be signed either with Microsoft’s key or a MOK key you’ve enrolled on the machine. In FOG’s case this means the FOS kernel has to be signed and trusted on the system, in addition to any other binaries (for example memtest, refind) you plan to boot via FOG.

    The other likely blocker is the build itself. Naturally, only iPXE can sign binaries that the iPXE Shim will support. Currently the FOG installer actually builds a slightly modified iPXE binary from source. While I’m unsure if these are all that different from the pre-built binaries from 2.0 in terms of support and functionality, it would at the very least need to be changed to instead pull the iPXE 2.0 binaries.

    I don’t think any of these are particularly hard to overcome or deal with though. The bottom line is, 2.0 makes it easier, but only to a point. To get real proper Secure Boot support in FOG, they’ll likely need to generate their own signing keys, and start signing at least the FOS kernels (if not iPXE itself) and update FOG to include shim support somehow.

    That said, for basic support, I doubt they would need to go the full mile and get a Microsoft approved signing key, I think distributing a certificate/key you can enroll via MokManager and using a pre-existing signed shim (like the iPXE provided one) would more than suffice for most usecases. I’m not sure how difficult it would actually be to implement any of this into FOG, that’s a question for someone who knows PHP and is more familiar with the FOG codebase than I.

    Sorry if that’s a bit long winded, it’s not an easy topic to distill. Hope that helps though.

    @Valer Hi Valer,

    You can see my tutorial on using Secure boot with Shim, and my thoughts on what 2.0 means for Secure Boot with FOG here: http://forums.fogproject.org/post/158170
