[SCRIPTS] Customization of Ubuntu - "Fog Service" for Ubuntu

ch3i

Hi,

I made two scripts to customize a master and enabled a “Fog Service” in ubuntu.
I used it in dual boot configuration (Win7/Ubuntu 14.04)

The first script - Cutom_My_Master (only launch on the master to prepare image) :

Update host (apt-get update / upgrade)
Modify Grub : Set timeout to 30s and default boot
Modify Gnome authentication : Disable login history
Enable Fog Service : add a service that allow to modify hostname, domain at startup/shutdown
Display a cool Hello Kitty at end (It was to justify my daughter why I was working at home)

The second script - host_rename_fog (it’s the “FOG client”) :

It’s installed as a service
Update hostname and domain by contacting Fog Mysql Server (at startup/shutdown)
-> Detect all networks cards and check if a mac address is present in Fog. If the hostname or domain is different it apply the update
->Turn all interfaces in DHCP in /etc/network/interface
-> Updating /etc/hosts and /etc/hostname
-> Remove persistent cards, very usefull in deployment
-> Automatically restart machine to apply modification, and modify default boot to ubuntu once time.

Howto :
1/ Copy paste the code below in two files (saved in the same folder) : Custom_My_Master (in my case) and rename_host_fog (the name is important for this file, it’s used to declare the script in the init process).
2/ Change right of Custom_My_Master : chmod 755 Custom_My_Master
3/ Modify the rename_host_fog to match with your fog installation
4/ Run Custom_My_Master : ./Custom_My_Master

Scripts :

Custom_My_Master

More slow because 10 seconds timeout in hostname.php request.

Sleep on hostname.php is removed, I’ll try to post a version with hostname.php instead MySQL request.

@Tom-Elliott It seem to be back

ch3i

Update host_rename_fog :

Add the “dots” function used in FOG scripts like the installer (more sexy lol)
Checking Mysql status
Update MAC/Hostname checking (a better compatibility with multiple eth cards)

To use that script please create a user in mysql database with select right only on tables : hosts and hostMAC !

2.0? At the rate I’m going I’ll have Linux and Mac released for 1.3.0

Cool, with 2.0 we have an Android/iOS client ?

Wayne Workman

@ch3i True, true. @Jbob says that the client complies and runs fine on Linux… which is pretty amazing.

IMHO, I’d say leave it as a request to MySQL. FOG 2.0 will not use PHP, it’ll use nodeJS and any PHP-based scripts out there will then stop working with FOG 2.0.

I know But I think in FOG 2.0 we have a linux client

@Tom-Elliott said:

@ch3i the sleep is an attempt to give the client system, booted into windows, a kind of delay so winmgmt has to to start up.

It’s possible to change sleep(10) with something like that :

$_REQUEST['delay'] ? sleep($_REQUEST['delay']) : sleep(10);

To specify delay using that :

<fog-ip>/fog/service/hostname.php?mac=f8:bc:12:6e:67:78&newService=0&delay=3

@Tom-Elliott Ok

is there a reason you chose to use a mysql query instead of using the built in mechanism of an http request to
<fog-ip>/fog/service/hostname.php?mac=f8:bc:12:6e:67:78&newService=0 
using the http request, you wouldn’t need to utilize database credentials

Hi,

I’ve tested with hostname.php it’s functional but very long…

Why there is a sleep during 10 seconds ?

sleep(10);
    // Make system wait ten seconds before sending data

Wayne Workman

@ch3i Wow you have been busy, very nice work!

ch3i

@cspence When I’ve wrote that script I only used FOG Database… But to minimize security problem I’ve created a read only mysql user.
If you can help me than @Junkhacker to optimize my script or create a FOG client for Linux, you are welcome lol.

@Junkhacker I’m trying to optimize security (I’ve discover service/class files on fog since 2/3 months), I’ll post a “FOG client” for linux (Redhat/Debian based during this month)

I forgot to tell you that you could choose to only install the “fog service” :

Post updated due to new Forum.
