Is it possible to remove the FOG Quick image password?

[Joseph Hales]

Yes it’s listed as one of the examples on how to edit the boot menu on the main FOG wiki.

i should point out that the example is a bit old and is listing the wrong location to find the init file.
it is now located in the web services directory ( /var/www on ubuntu) in /fog/services/ipxe/ and there will be 2 separate versions, init.xz and init_32.xz, for 64 and 32 bit respectively.

[Tom Elliott]

I should point out that quick image is not performed (at all) from the init any more.

[Joseph Hales]

I don’t have edit access on the wiki maybe one of you can revise the entry.

[Darkzion]

Thanks for all the answers guys. I found the files and did the procedure above. unfortunately it did not work.
Im guessing it has something to do with what Tom Elliot wrote.

Tom: Do you know where quick image is performed from ?

Thanks Guys

[Junkhacker]

for any host that is registered, quick imaging is now done by scheduling a task on the server side. i hadn’t looked at the scripting and assumed it would pass the login info to the fog server components to schedule a task, but this is old code from the way it was done before.

[Darkzion]

Thx guys.
But it seems that we have still not managed to find a solution to this problem.
We have done all above but the password screen on quick image is still popping up.
Any other suggestions ?

We found a “BootMenu.class.php” file and other php files but we havent found any way to disable the password screen yet.

[Tom Elliott]

This is actually really simple to accomplish.

In the file that you found (/var/www/fog/lib/fog/BootMenu.class.php:

Look for the four lines:
[php] else if ($_REQUEST[‘qihost’] && !$_REQUEST[‘imageID’])
$this->setTasking();
else if ($_REQUEST[‘qihost’] && $_REQUEST[‘imageID’])
$this->setTasking($_REQUEST[‘imageID’]);[/php

They are at about line numbers: 655 thru 658

Place the lines in the else statement at line 677? right after the curly brack. Remove the first else in the statement so it’ll look like:
[php] if ($_REQUEST[‘qihost’] && !$_REQUEST[‘imageID’])
$this->setTasking();
else if ($_REQUEST[‘qihost’] && $_REQUEST[‘imageID’])
$this->setTasking($_REQUEST[‘imageID’]);[/php]

This won’t, by itself, keep the system from requesting a username and password, but all you should have to do is press enter.

With that you still have to select which image (if host has image already, it defaults to point at that hosts image, but you can choose any you please.)

An even better method would be to just remove the:
[code]login[/code]
from the fog.quickimage database entry.

Replace the lines
[code]param username ${username}
param password ${password}[/code]
With something like:
[code]param username fogusername
param password fogpassword[/code]
In the fog.quickimage database entry.

This should keep it from asking about a username and password as well as allow BootMenu.class.php to remain un touched.

I’ve decided, based on the multiple people wanting to customize the main boot items directly even, to re-enable editing so you can do this from the GUI now as well. So you don’t have to edit a file and you can make your changes
as needed.

[Darkzion]

Thank you very much Tom.
We updated out build with the newest release on the dev branch and as you said, its now possible to edit this from the GUI.
We did as you said and changed the param and removed “login”. And now it skips the login screen and lets us select the image right after clicking quick image

But unfortunately it seems like the password autentication might still be required somewhere in the code.
Because as soon as we click a image that we want to have installed. It jumps us back to the “fog menu” .
With no error message other than a quick “returning to menu”.

Best regards

Do you have anything in your apache error logs?

A good way to get the most out of the information:

Start your client and get it “ready” to select an image to push but don’t choose an image yet.

Open a terminal/ssh to your fog server. Run:
[code]sudo tail -100f /var/log/apache2/error.log[/code]

Press enter on the the image you want to push to the client.

Press CTRL+C on the ssh terminal. The last few lines of the error log should give you where the problem is.

Thank again Tom.
According to the apache logs i keep getting this >

[Fri Feb 20 16:55:48.371529 2015] [:error] [pid 2376] [client 172.16.200.14:33459] PHP Warning: array_unique() expects parameter 1 to be array, null given in /var/www/fog/lib/fog/HostManager.class.php on line 8

Every time i click “quick image” from the main menu, and every time i click on a image on the next menu.But dont think thats related. This only happens when i havent registered the host. If i register it. Then i dont get any error message at all in the error log. But it still kicks me back to the main menu when i select an image

[Tom Elliott]

I’ve found a solution:

For the fog.quickimage menu item
before the params setting put:
[code]set username fogguiusernamehere
set password fogguipasswordhere[/code]

Reset the param username and param password back to:
[code]param username ${username}
param password ${password}[/code]

This should work at least in my testing it has.

[Darkzion]

Thanks again Tom.
Im sorry for the late reply. Been out of the country.
I just wanted to say that the last solution you gave fixed it for us.
Thank you so much for your help

[Mikael]

For the extra clarity, this worked for me. Edited /var/www/fog/lib/fog/BootMenu.class.php, the rows just below "…$option == ‘fog.quickimage’)

//              print "login\n";
				print "set username username\n";
				print "set password password\n";

/Thanks!

[lebrun78]

is it always available on 1.3.3 version ?

[Tom Elliott]

@lebrun78 Is what always available?

[lebrun78]

@Tom-Elliott
Is the procedure described above?

the file fog.quickimage doesn’t exist on base 1.3.3.
Should I add it ?

[Tom Elliott]

@lebrun78 What procedure?

iPXE menu items have never been “files” either.
