Problem with iPXE booting to Fog: "/default.ipxe permission denied"

[Tom Elliott]

@dwr I’ve seen this problem on numerous occasions. What you’re seeing isn’t necessarily what is actually going on. It’s trying to load the files but it tries to do so improperly. This does not happen on all systems though. And because of the nature of the problem, seemingly specific to debian OS’s I’ve made corrections for this in trunk/dev versions of fog. Please give that a shot.

@dwr On my system it does not matter if I get ‘default.ipxe’ or ‘/default.ipxe’. Both get properly downloaded. Maybe it’s just file permisson problem.

ls -al /tftpboot
...

Sorry pal, when you say “give that a shot”, do you mean downloading the latest dev version of Fog and installing that instead?

I think it would yeild you much better results. You could even just try the files we have in trunk for ipxe. They are found in:

https://svn.code.sf.net/p/freeghost/code/trunk/packages/tftp

@Tom-Elliott apologies for being a moron, would it literally just be a case of replacing the files in my /tftpboot folder with those in trunk?

[Tom Elliott]

@dwr Pretty much yes.

OK I’ve tried those files and nothing has changed.

I’ve just had a look at my /etc/xinetd.d/tftp and the config doesn’t quite match up with the settings I found here: https://wiki.fogproject.org/wiki/index.php/Unable_to_connect_to_TFTP

My config has the user set as nobody. If I change that to root and then restart the xinetd serivce, I get an entirely different error:

So… does that mean it could be permissions?

@dwr When you access your fog server GUI, what is the URL you go to?

If you go to the url: http://192.168.3.250/fog/service/ipxe/boot.php what does it give you?

Well… I have no idea what’s going on now really, but I’ve changed the config again (it wasn’t the root bit that was important, I was missing -s from the server args)… and then when I was checking the MySQL username/password, I found that MySQL had bugged out. I restarted the service and I can boot to FOG!

Woo

Cool, so I’ve solved this thread then. Thanks for reporting back.
