Boot.php permissiondenied

[Xibeaga]

Yes, it reads:
drwxrwxrwt /tmp

[Tom Elliott]

What’s in the /etc/fstab for the /tmp?

[Xibeaga]

tmpfs /tmp tmpfs defaults,noexec,nosuid,size=10485760 0 0

Remove the ,noexec and restart your system.

Then try rerunning the installer.

[Xibeaga]

okay, i did.
now install runs clean (including correct UDP cast)

but when i try to pxeboot a client: boot.php permission denied
the fog boot-menu never show up

[Tom Elliott]

I am only working off of theory here:

You have a redirect somewhere? Maybe you’re trying to go: hostnameoffog without actually go to hostnameoffog/fog

What’s happening (in my theory) is the file is searching for:

hostnameoffog/fog/service/ipxe/boot.php

But because of the redirect, it’s trying to go to file:

hostnameoffog/service/ipxe/boot.php

Because hostnameoffog/service/ipxe/boot.php doesn’t exist, it’s not able to find it, hence permission denied.

[Xibeaga]

Hm, no, I only use next-server-option at my DHCP, everything else does not have any redirections.

[Tom Elliott]

Is next server pointing at the proper server?

[Xibeaga]

yes. It all runs fine until boot.php

[Junkhacker]

what is the contents of your default.ipxe file? have you changed the IP of the server since you installed?

[Xibeaga]

this: IP looks fine

#!ipxe
cpuid --ext 29 && set arch x86_64 || set arch i386
params
param mac0 ${net0/mac}
param arch ${arch}
isset ${net1/mac} && param mac1 ${net1/mac} || goto bootme
isset ${net2/mac} && param mac2 ${net2/mac} || goto bootme
:bootme
chain [url]http://172.16.3.93/fog/service/ipxe/boot.php##params[/url]

[Tom Elliott]

I’m under the impression something else is going on.

Is the ONLY error a Permission denied on the boot.php, or are there (even a flash) of a few more lines? Maybe something along the lines of Console error or what not?

[Xibeaga]

Okay, here is a screenshot, maybe this helps.

Well the good news is its not really the boot.php that’s having the error but I’m not sure where the boot script is failing.

Can you set the permissions for the while service ipxe folder? Maybe: [code]chmod -R 777 /var/www/fog/service/ipxe[/code]

Also can you give us your Apache error log directly after this occurs? Also is thus happening on all systems.

[Xibeaga]

Okay, i did. no change to the behaviour.

I recognized that dir ipxe is not owned by “www-data” but by “fog”, the contents of ipxe are also owned by “fog”
everything else is owned by “www-data” it seems.

And YES this appears on all clients, also with different hardware

How i generated the logfile:

1. I stopped apache
2. i deleted all logs
3. i launched apache
4. i pxebooted a client
5. stopped apache
   Unfortunately ther is exactly 1 line in the logfile:

---

172.16.3.51 - - [27/Nov/2014:22:15:43 +0100] “POST /fog/service/ipxe/boot.php HTTP/1.1” 401 722 “-” “iPXE/1.0.0+ (3a02)”

[Xibeaga]

I Found it!
*** OUCH ***
The apache-log revealed it: HTTP 401 is the problem. 401 -> user authorization required!!!
/var/www was protected by .htaccess sigh

I am really sorry to have bothered you with this, on the other hand: I would have had no chance to figure it out without your hint to check the apache-log

THANKS A LOT !!!
Best regards!

No problem and glad to be of some kind of assistance. The folder should be owned by fog and www-data/apache. This is specific to allow kernel updates to work properly.

[Xibeaga]

Hey, konw I know lots more about fog than i used to know, and i use it since 0.30 or so
