Here’s the process I did with Fog 1.3:

Installed FRESH Centos, updated, installed git, wget, nano, and disabled selinux

Downloaded and installed Fog 1.3

Upgraded PHP from 5.3.3 to PHP 5.5

Created 2 Usernames

Installed and configured dnsmasq

hid a couple of menu items

created an image for the host to image to

booted into the menu, and then ran into kernel panic problems

@Tom-Elliott

It is NOT loading from tftpboot at all, as I mentioned it’s loading from /var/www/html/fog/service/ipxe/

Something just tells me this isn’t worth the effort at this point. I really don’t know what to say, I don’t have another full day to waste messing about with this, re-installing Fog just isn’t an option since this will be the 4th time in the last week I’ve done and always ran into problems, so sounds as though I’m looking for another solution

@Tom-Elliott
It’s loading them from /var/www/html/fog/service/ipxe/

Now what’s weird is unregistered hosts get to the menu OK but a registered host doesn’t …however still have the same Kernel Panic I did before…so frustrating lol

edit: figured this out by renaming init.xz, now when I try to get to anything from the menu it fails chainloading that file instead of the Kernel Panic (init.xz IS in my /tftpboot/ folder, but isn’t referenced in any config files to boot from there

@george1421
Hey I didn’t run away, just had a conference call to do…the device is a Lenovo T420 laptop with an Intel Series Ethernet Controller (I can’t recall the exact info on it).

When i re-loaded the images that you linked now I’m getting a kernel panic before the menu loads…same panic, earlier in the boot sequence.

Since I didn’t change anything for the “mode” I’m assuming it’s Legacy mode…

The TFTP service serves out the boot.php file but then it hangs, tries to get init.xz and bzImage, then throws a Kernel Panic at me -_-

@george1421

Still Kernel panic but no more prompt for a TFTP Server IP so one thing fixed lol

When the system loads past the menu I get
bzImage…ok
init.xz…ok

and then this is where the Kernel Panic happens…it just makes no sense to me

I have my dnsmasq almost identical to your .conf file (I’m on CentOS 6.8…)

Think I should try copying the known working bzimage and xint.xz files and see if that helps?

I was literally just adding that into my config right now hold tight (it probably will solve the TFTP server IP prompt too :))

LOL oops that was after I saved it to try something…the symlink is to:

lrwxrwxrwx   1 root root     13 Sep 15 11:31 undionly.kpxe.0 -> undionly.kpxe

Sorry I saved the pxelinux line to test something out…and it failed, I wonder if it’s these particular versions of the init and bzimage files? perhaps it doesn’t jive with an older system - I’m gonna try another machine hang on

edit: I get the real job stuff too, I’m stick handling this and trying to sort out some Microsoft Licensing at the same time as I’m trying to fix a Wordpress install LOL

I didn’t actually do much on the Fog 1.3.0 side of things other than hide a few menu items…so the config there shouldn’t be anything there that would have gotten out of sync…

There’s not much in it just what is needed to be honest. I’m really at a loss here, the bzImage and init.xz from fog 1.2 worked perfectly fine, it’s only on 1.3 RC10 that I ran into this problem…

@george1421
Oh don’t I know it -_- The trouble is the client wanted to spend as LITTLE money as possible on this (saves about $250-300 a month in courier costs…), and since they felt this was more important than me upgrading their Active Directory to something…I dunno…supported…I’m stuck dealing with hopping into a hard situation (cause…it can never be easy, where would the fun be if it was all easy? :P)

I tried with both the 32 bit and the 64 bit version of bzImage/init.zx and the same error still comes up. I wasn’t getting it on the previous version of fog, then again I think I was sending it pxelinux.0 as the boot kernel. I’m just not sure where to go with this one (I’ve done plenty of PXE boot situations…back in the popular Norton Ghost days lol

edit: I do have access to the DHCP server, I just can’t use it because of the way the last IT guy setup the network

@george1421

From my dnsmasq.conf:

tried with:
dhcp-boot=undionly.kpxe

and
dhcp-boot=undionly.kpxe.0

I have a symbolic link created:
undionly.kpxe.0 -> undionly.kpxe

Sep 15 12:06:37 fog13 in.tftpd[13306]: Client 10.84.52.191 finished default.ipxe

Not sure if default.ipxe should be the right file for it to get…I dunno I might go back to figuring out how to get my system to load WinPE and use the software they already have licensed and have used before, this is getting a little discouraging lol

@george1421

Currently, my customer’s network is all Server 2003 based (JOY…that’s a big upgrade project all on its own…), they’re using Mikrotik Routers for DHCP, but all of the Phones and Machines are on the same subnet - I didn’t set it up, I sort of inheritted this setup…it’s not how I’d do it at all (VLAN1 or 10 for Data, VLAN 20 or 99 for Voice, segment broadcast traffic, and give a /24 to both networks…don’t allow routing between the 2 VLANs…etc :))

Anyways, so my setup is Fog 1.3 RC10, DNSMasq for doing ProxyDHCP…I found another thread on this but the fix in there didn’t work (maybe my dnsmasq settings are wrong? or I’m having it choose the wrong image of sorts).

First I’d like to say: YAY for menu editing in the GUI! No more source file hunting

Second, whenever I choose an option (i.e. Quick Registration and Inventory), it loads up bzImage and init.xz, and then shows:

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(1,0)
Kernel Offset: disabled
—[end Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(1,)

…this is an x64 system, but I can’t find in the menu setups where to change to init32.xz (if I remember the documentation correctly, that should be used on x64 systems)

Any ideas?

Hey everyone, thanks for the responses - I was tied up most of the time after I posted so this is the first I was able to get back to this.

2 things:

1. Instead of trying to figure out if I could upgrade from 1.2 to 1.3RC10 I just created a new VM, installed CentOS 6, GIT, and installed from the GIT repo for 1.3 RC10

and

2. The version of PHP installed by 1.3.0 RC10 needs upgrading away…it installed 5.3.3, minimum is 5.5 - I upgraded PHP and it was fine after that.

There are a fair number of changes to the menus in this version…as well as some of the imaging options (for the better so far - I’ve only been on it for about 10 min or so…)

I’m going to add an image to the system to make sure that’s fine and then I’ll go from there (it takes a while since it’s a larger image (compressed it’s 21 gigs…)…once I have this image and an image of the other laptop, I’ll mess about in the menus but there is a “Deploy Image” option in the menu which wasn’t there before.

The only question I have right now is…if I’m not using DHCP to set TFTP options on boot, is there any way to bypass it asking me for the TFTP Server? (Can’t use the DHCP options on my clients networks, their IP Phones use the options already, so DNSMASQ with ProxyDHCP works all the same for me…but I don’t want them to have to type in the IP of the TFTP server each time it PXE boots.

@george1421
That’s the idea anyways, I don’t want them booting off PXE unless they NEED to, so my instructions already included using the F12 option (I don’t need these people complaining that they messed up the boot order on their computer…since they have a hard time typing subdomain.domain.com sometimes…lol I don’t care if they image with the wrong image (the 2 laptop Models aren’t all that different, just a few drivers here and there are different)

---

I’ll update this post later on, I’m setting an image to write and then finding something to do for 2 hours…maybe I’ll play around with the Bios Mod I need to do for the one laptop model

I can’t seem to find a straight forward answer to this. FOG seems to be the right choice for what I need to do, but…I don’t need the management side of the PXEMaster. I’ve looked up and tried a few different ways to implement this and I just can’t figure it out, hoping someone on here can help. I have a client that needs to be able to re-image their laptops without me being there, I can understand this since one of the sites is halfway across the Province from me…

So I came across FOG, which will create images and distribute them for me, GREAT, but I don’t need some of the management things, like host registration and tasks. I found one link to accomplish this:

https://wiki.fogproject.org/wiki/index.php?title=Bypass_Host_Registration

However, I just can’t wrap my head around the instructions. I figured out I could go into the BootMenuClass.php to find the options displayed in the menu that iPXE boots into…fantastic…however this is where I’m stuck

1. I want to remove items from it - the client will never be in here and need to boot from hard disk, they will never ever be running memtest…
   and
2. Add links to specific images that are pulled from 2 Laptop models.

The Management interface would only be for myself to be able to create new copies of the images being sent to their locations, this is done for version control so that I don’t have someone say “oops” and overwrite the image for their laptop and then me trying to figure out what they did wrong…hence the lack of needing management capabilities for laptops enmass.

So if I had to give an example I’d probably want something like:
:t420tech
kernel bzImage32 root=/dev/ram0 rw ramdisk_size=127000 ip=dhcp dns= keymap= web=10.84.52.195/fog/ consoleblank=0 loglevel=4 mode=manreg
imgfetch init_32.xz
boot || goto MENU
:t420tm
kernel bzImage32 root=/dev/ram0 rw ramdisk_size=127000 ip=dhcp dns= keymap= web=10.84.52.195/fog/ consoleblank=0 loglevel=4 mode=autoreg
imgfetch init_32.xz
boot || goto MENU
:t500tech
kernel bzImage32 root=/dev/ram0 rw ramdisk_size=127000 ip=dhcp dns= keymap= web=10.84.52.195/fog/ consoleblank=0 loglevel=4 mode=sysinfo
imgfetch init_32.xz
boot || goto MENU
:t500tm
kernel bzImage32 root=/dev/ram0 rw ramdisk_size=127000 ip=dhcp dns= keymap= web=10.84.52.195/fog/ consoleblank=0 loglevel=4 mode=sysinfo
imgfetch init_32.xz
autoboot

…but I haven’t the foggiest idea how to tell the server to pull up the image files properly…or where I can add this in…my brain is running on empty so nothing is really sinking in from the docs…if someone can give me some insight on this it’d be appreciated.

Essentially I just want them to be able to boot up…and say “Oh this is a tech’s Lenovo T420, so I’ll highlight T420 Tech and press Enter” and it’ll pull THAT specific image from the FOG server…
