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

Post updated due to new Forum.
Enjoy

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

Junkhacker

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

Maybe he likes to live dangerously.

@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)

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

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

Tom Elliott

@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.

ch3i

@Tom-Elliott Ok

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

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

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

Wayne Workman

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

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 ?

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 !

@Tom-Elliott It seem to be back

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