chainloading failed advanced menu

What exactly do you mean? I just installed a fresh 1.5.4 test system and it looks exactly the same to me. FOG_PXE_ADVANCED empty and no field to edit it.

If I look at my fog server running 1.5.4 I can enter an Advanced menu command, because the field (edit box) is there. If you look at what Scott posted below he doesn’t have the box to enter anything in and he’s using 1.5.5.3 https://forums.fogproject.org/topic/12911/chainloading-failed-advanced-menu/5

I don’t know why the menu is being displayed in the iPXE side, but the first is to be able to edit in the webui. The rest is executing “I think” correctly. Its possible that the advanced menu field has a single white space in it causing the menu to be displayed in the ipxe side. I didn’t do a length in my query.

@george1421 Can’t stop laughing. We all seem to have stepped into the same puddle of mud here. I figured that the field is not being displayed because AdBlock Plus Firefox Add-in is blocking it!!!

The rest is executing “I think” correctly.

Sorry, no. There is an issue in the advanced.php as mentioned earlier. As soon as Scott has fixed that in the code (manually for now) and maybe disabled AdBlock for this site to be able to edit that field he should be all up and running.

But still I am wondering about the structure of this. When you got to FOG Configuration -> iPXE Menu Item Settings -> fog.advanced. From my understanding this is how the advanced menu was meant to be used at some stage but was never finished. Maybe I am wrong here. @Tom-Elliott is the only one who can tell us I suppose.

I’ll push that one fix to github for now and we’ll see about the rest later.

Yeah, I got that upside down. Has been a long time since I last used it. iPXE Menu Item Settings is just that, the menu definition itself. Those should be fine for Scott as far as I see (only issue which should not cause trouble is the && you have, make this && in the fog.advancedlogin so you won’t have that isset message on screen). Now after the menu item (login or not) it proceeds to load what is defined in the “Advanced menu command” field (disable AdBlock Firefox Add-in to see that). For that to work you need to fix that code in /var/www/html/service/ipxe/advanced.php as mentioned before.

The “Advanced menu command” field needs to begin like this:

#!ipxe
...

I made the change to /var/www/html/fog/service/ipxe/advanced.php as suggested. The menu still isn’t working but does a few extra errors about Exec format as seen in the image below.

[Sebastian Roth]

@Scott-B What have you set in the “Advanced Menu Command” field?

It’s blank and uneditable.

[Sebastian Roth]

@Scott-B As mentioned yesterday you need to disable Firefox Add-in AdBlock Plus to see the field. Not sure why that is but I figured that was blocking the field for me. Pretty sure it’s the same for you.

Doh! I must have only allowed it temporarily. The field is there now. It’s blank.

[Sebastian Roth]

@Scott-B Well then start adding your advanced menu code here:

#!ipxe

That get’s me past the chainload error and drops me off at a blinking cursor.

[Sebastian Roth]

@Scott-B You need to define a proper menu code yourself. The ... is not enough. Who designed your advanced menu last time?

I think we are good. I was able to add DBAN back to the menu list.

OK great this is what we were seeing in the database with our sql query. Somewhere along the way this field must have been reset. You will need to hand code this menu entry for it to work correctly. I can tell you that by using the boot.php url I provided below which was displayed in your browser, you can see the structure of what you need to include in your advanced menu design.

@Sebastian-Roth what kind of shady stuff are you doing to have that field blocked by the ad blocker?? <just kidding> I wonder why this field still exists? If you look in the ipxe menu configuration there is a field Menu show on, some options are Advanced menu and Advanced menu with password. Were these options never implemented? I had the idea to make just a checkbox in the ipxe menu configuration to be advanced menu but it looks like someone already thought of that??

Yeah I was mislead by that as well. Those two are just the entry points for the Advanced Menu. Without login -> no ipxe code needed -> will lead you straight to Advanced Menu Command definition. With Login -> do the Login (defined in the menu entry) -> then on successful login run same Advanced Menu Command. Might be a bit confusing at first.

[Sebastian Roth]

Marking this solved now as I have just pushed a fix to the dev-branch…

Seems like not very many people use this stuff at all. The issue has been in the code for a long time - even in 1.5.0 and probably earlier (didn’t look back further). But possibly this issue came up with an update of iPXE. Anyway, should be fixed now.

@Scott-B Be aware that I just re-added the #!ipxe stuff as other users told us the advanced menu is broken for them now: https://forums.fogproject.org/topic/13230/advanced-menu-bug

This is only in the current development version but it will also be in the next release 1.5.7. Just so you know in case you update to that or a later version at some point in time.
