We’ve decided for now to just boot to Windows, and set the thing up so that we can test it “on the floor”. If it behaves like it should, we’re gonna buy some other ones to replace older devices currently in use. When we do that, I’ll have more time to play with capturing/deploying it so make our life easier So you guys have plenty of time to think about this weird piece of hardware, and I’ll get back to this thread when we have more devices to play with!

Thanks all for the help so far!!

Great find! This is really unusual. Have never seen this before! Why would if not be able to read the MAC I wonder?!? Random MAC is kind of breaking the whole FOG logic of identifying hosts via MAC address.

Exactly. And I’m pretty sure there IS a mac address in the nic: when I enable uefi and let it network boot, I see always the same mac address. Would it be possible that it uses a different nic with uefi disabled?

[edit] note web will only be there when you are in capture/deploy menu mode not in the debug mode from the menu entry.

Ok, that explains why the $web variable doesn’t exist in debug-mode, and why the fog script doesn’t work then.

I understand this (linux) is a alien world to most windows folks. But you see there IS a lot of magic that goes into make FOG functional and universal.

You have the unfortunate situation of having very strange hardware (maybe one of a kind) that make imaging difficult to manage. FOG has a lot of instruments in the band, its takes a bit of cohering to get them to all play the same tune.

I do have some linux knowledge, and understanding some scripts would not cause too many problems. But it’s the (network)boot-process that I don’t know anything about. Like you say, trying to understand that, together with the fog scripts, and some weird hardware, makes the step too big. If I really want to learn how fog works, I’d better start with some normal hardware

bmaster001

It’s a difficult mechanism to understand. A lot of unfamiliar technologies, scripts and boot-arguments working together. It’ll take a while for me to better understand it. But it’s a very interesting subject!

The very first line in the fog script is the call to funcs.sh. when I run that on the command line, and do set, I see no web variable:

_=/usr/share/fog/lib/funcs.sh
acpi=off
boottype=usb
consoleblank=0
has_usb_nic=1
init=/sbin/init
isdebug=yes
ismajordebug=0
loglevel=7
name=has_usb_nic
oIFS='
'
ramdisk_size=127000
root=/dev/ram0
rootfstype=ext4
value=1
var=has_usb_nic=1

bmaster001

That seems to work! I’m now stuck on the ntfs inconsistency again that’s not fog’s fault… I’ll have to find a way to fix that too.

Before doing what you described, I took a loog at the contents of /bin/fog . It starts like this:

### If USB Boot device we need a way to get the kernel args properly
if [[ $boottype == usb && ! -z $web ]]; then
    mac=$(getMACAddresses)
    wget -q -O /tmp/hinfo.txt "http://${web}service/hostinfo.php?mac=$mac"
    [[ -f /tmp/hinfo.txt ]] && . /tmp/hinfo.txt
fi $

The $web part seems to be a problem, because that variable doesn’t exist. So it skips the getMACAddresses-part…

@george1421 said in another init.xz issue:

@bmaster001 I saw the kernel driver, but not sure what you wanted to tell me. I assume the driver is built into the current FOS kernel otherwise you would not get an ip address.

In that source you can see that the driver tries to get a MAC address from the EEPROM but if that fails, it generates a random one. I thought that it might help to know that it’s the driver who does this, and not some weird config option somewhere…

Another thing that I’ve tried is to boot in debug mode, and manually add a host to the fog server with the random mac. Then schedule a capture task, and run ‘fog’ on the host. It fails with the “unknown request type :: Null” error. Maybe you know if there’s a way around that?

Thanks a lot for you help anyway, I’ve learned a lot! Let’s hope someone else with a deeper knowledge of this stuff is willing to look at this!

FYI: I’ll be on vacation from coming friday until the 3rd of july…

Whene I add that, it asks me to unplug and replug my device into the usb port and press enter. Can’t do that, so I just pressed enter

Anyway: the result is the same: another random mac address…

It’s not a usb-stick, but I think internally it’s a usb connection. Here’s the output for lsusb:

I went to http://www.linux-usb.org/usb.ids to lookup if it knows the devices, and the 0424:ec00 is a “SMSC9512/9514 Fast Ethernet Adapter”. Don’t know if that helps?

EDIT: dmesg also mentions this device and the mac:

oh, I thought that was a type, sorry for that. But it doesn’t help, the set command doesn’t give me anything mac-related:

[Tue Jun 21 root@fogclient ~]# set |grep mac
SHELLOPTS=braceexpand:emacs:hashall:histexpand:history:interactive-comments:monitor:posix
[Tue Jun 21 root@fogclient ~]#

And here is the lspci output:

Thanks for the “secret”

First run:

[Tue Jun 21 root@fogclient ~]# ip addr show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

    inet 10.1.14.214/16 brd 10.1.255.255 scope global eth0
       valid_lft forever preferred_lft forever
[Tue Jun 21 root@fogclient ~]# /usr/share/fog/lib/funcs.sh
[Tue Jun 21 root@fogclient ~]# set |grep mac
SHELLOPTS=braceexpand:emacs:hashall:histexpand:history:interactive-comments:monitor:posix

I think the funcs.sh script doesn’t output anything mac-address-related into a variable. I looked in the script, and saw that it runs /sbin/ip which returns basically the same info as ip add show or ifconfig.

Second run:

[Tue Jun 21 root@fogclient ~]# ip add show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast qlen 1000
    link/ether 96:c1:60:13:b0:09 brd ff:ff:ff:ff:ff:ff
    inet 10.1.14.248/16 brd 10.1.255.255 scope global eth0
       valid_lft forever preferred_lft forever

Third run:

[Tue Jun 21 root@fogclient ~]# ip addr show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast qlen 1000
    link/ether ce:82:f1:bb:00:6c brd ff:ff:ff:ff:ff:ff
    inet 10.1.14.190/16 brd 10.1.255.255 scope global eth0
       valid_lft forever preferred_lft forever

I think this confirms what I already saw: the mac address changes on each reboot
