Is it possible to remove the FOG Quick image password?

[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.

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!

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.

@lebrun78 I still don’t understand what you’re talking about.

You posted to a thread that’s over a year old since it’s last communication asking about a procedure that I still don’t know what you’re looking for.

The IPXE menu stuff is handled on the GUI now. the fog.quickimage script from the init’s perspective doesn’t exist which was already discussed in this thread as well. (https://forums.fogproject.org/topic/4433/is-it-possible-to-remove-the-fog-quick-image-password/3#)

I don’t know what it is you’re asking or trying to accomplish.

[lebrun78]

indeed, I’m a drag

[Tom Elliott]

@lebrun78 what are you trying to do? I can’t help without understanding what you are looking for.

[lebrun78]

I would like, for a group of machine which the name is beginning by i207, not have to insert login/password to deploy image directly from pxe menu.
But for all the other machines I would have to keep the login/password

[Wayne Workman]

@Tom-Elliott this is what he’s trying to do: https://forums.fogproject.org/topic/9290/boot-menu-configuration-document

@lebrun78 For the one classroom that you want to not manage, give them their own server on their own vlan, or give the teacher ‘mobile’ access only. Or schedule the machines to just get imaged every single night or weekend or whenever the teacher requests the classroom be imaged. You can just schedule these things, we can walk you through it. Also it’s not hard to use groups to deploy whenever it’s requested either. If you’re using the FOG Client and DHCP and have WOL enabled, and you have systems set to boot to the network first, you can deploy to a classroom without being there and all will be fine.

The amount of work involved with you continuing to do all of the imaging is not that much when your environment is setup to your advantage.

thanks for your answer

[lebrun78]

I tried modify the fog.deployimage with this code:

#login
params
param mac0 ${net0/mac}
param arch ${arch}
param hostname ${hostname}
goto host_${hostname} || goto autres
:host_admin13
param username toto
param password toto
param qihost 1
isset ${net1/mac} && param mac1 ${net1/mac} || goto bootme
isset ${net2/mac} && param mac2 ${net2/mac} || goto bootme
goto fin
:autres
login
param username ${username}
param password ${password}
param qihost 1
isset ${net1/mac} && param mac1 ${net1/mac} || goto bootme
isset ${net2/mac} && param mac2 ${net2/mac} || goto bootme
:fin

My test machine admin13 goes into the loop host_admin13, but login and password are not valid.
It may be a coding problem for the password ?

[lebrun78]

login toto and password toto is a mobile account
