Version 1.5.9 default directory for iso

petec · Feb 18, 2022, 9:49 PM

Hello World
New with FOG here and im trying to use it for pxe boot. I do find tutorials online for older versions mentioning that the images should go under root-tftpboot but on the new version the directories are different. so where do i upload iso’s for pxe in this version.

thank you for your help in advance

@petec It depends on the FOG server’s linux os, but most are now in /tftpboot directory.

@petec I think the answer depends on how you want to PXE boot the stuff. If you want to use slow TFTP, then they go in /tftpboot but there are other options, like HTTP and if you are pretty keen you can even extract the ISO and make it PXE boot over NFS. So it all depends.

@george1421 I’m on centos 7

george1421 · Feb 21, 2022, 12:58 PM

@petec /tftpboot is the right directory then. But as Sebastian said, there are many methods of pxe booting once you get iPXE loaded into memory. The PXE Rom only supports tftp protocol, so iPXE will need to be transferred via tftp. Once iPXE is running then you can use other protocols like NFS and HTTP(S), which are much faster protocols than tftp.

depends on how you wa

I think i figured out how the directories work. Now i upload and extract Gparted inside /tftpboot/gparted and i set these parameters according to a tutorial i found online:

kernel fog/gparted/live/vmlinuz
append initrd=fog/gparted/live/initrd.img boot=live union=aufs noswap noprompt vga=788 fetch=http://10.0.0.2/fog/filesystem.squashfs

The client gives me the following error:

fog/gparted/live/vmlinuz…ok
append command not found

Any tutorials or examples for 1.5.9 that work?

@petec said in Version 1.5.9 default directory for iso:

append initrd=fo

This is a syslinux command not iPXE. You want imgargs keyword for kernel parameters. https://ipxe.org/cmd/imgargs

@petec said in Version 1.5.9 default directory for iso:

kernel fog/gparted/live/vmlinuz
append initrd=fog/gparted/live/initrd.img boot=live union=aufs noswap noprompt vga=788 fetch=http://10.0.0.2/fog/filesystem.squashfs

But I can also tell you this is wrong too. I would rewrite it as

kernel /fog/gparted/live/vmlinuz
initrd fog/gparted/live/initrd.img
imgargs vmlinuz initrd=initrd.img boot=live union=aufs noswap noprompt vga=788 fetch=http://10.0.0.2

This command might still give you some problems if you don’t have what its wanting to fetch in the right location.

You might want to review this post: https://forums.fogproject.org/post/140524 since it appears similar to your imgargs

@george1421 said in Version 1.5.9 default directory for iso:

/fog/filesystem.squashfs

so here is the current config, with all the paths checked.

kernel /fog/gparted/live/vmlinuz
initrd /fog/gparted/live/initrd.img
imgargs vmlinuz initrd=initrd.img boot=live union=aufs noswap noprompt vga=788 fetch=http://10.0.0.2/fog/filesystem.squashfs

Error

Could not select: Exec format error

im kinda lost. Most of the info online are for the older versions.

george1421 · Feb 22, 2022, 2:52 PM

@petec That message “Exec format error” is because something is wrong with vmlinuz. Either its not in the right path, the file is corrupt, or something else was keeping it from starting up.

Confirm that your kernel is in
/tftpbboot/fog/gparted/live on the fog server

you can also use the linux command file /tftpbboot/fog/gparted/live/vmlinuz to read the kernel header.

Remember for the different protocols, they have different doc roots on the FOG server.

tftp: /tftoboot
nfs: /images
http: /var/www (for debian variants) /var/www/html (for rhel variants)

petec · Feb 22, 2022, 8:55 PM

@george1421 said in Version 1.5.9 default directory for iso:

file /tftpbboot/fog/gparted/live/vmlinuz

Its the right path,

[root@bootserver html]# file /tftpboot/fog/gparted/live/vmlinuz

/tftpboot/fog/gparted/live/vmlinuz: Linux kernel x86 boot executable bzImage, version 5.10.0-8-amd64 (debian-kernel@lists.debian.org) #1 SMP Debian 5, RO-rootFS, swap_dev 0x6, Normal VGA

george1421 · Feb 22, 2022, 9:01 PM

@petec You are seeing it transfer the kernel and the init? Do you have a screenshot of the error (clear picture taken with mobile phone)? If the path is right and the kernel is right, ipxe should at least try to boot it.

petec · Feb 22, 2022, 9:24 PM

@george1421 ![alt text]

Im confused too. i attach an image!

george1421 · Feb 23, 2022, 4:23 PM

@petec Your screen shot doesn’t show its downloading the initrd image before it tries to boot the kernel. That is strange. The kernel should boot without the initrd only so far, but it should boot.

So the next bit is to help a bit more with debugging. In the web ui ->FOG Configuraiton -> FOG Settings menu. There should be a value for logging level. It may be 1 or 4, turn it up to 7. This will inform the linux kernel booting to send all log messages to the console. This should give us a bit more detail.

The next bit is to use a windows web browser and browse to http://<fog_server_ip>/fog/service/ipxe/boot.php?mac=00:00:00:00:00 This will print out a bunch of text, copy and paste that text into a new post. That is the iPXE menu commands that builds the FOG iPXE menu. I want to look at the configuration for your menu. There has to be something off here.

@george1421

Keep in mind that the photo is EFI, if i do Legacy is downloads it and then comes to the same error

george1421 · Feb 23, 2022, 3:14 PM

@petec OK here is the part of the menu that seems to be causing the problem.

kernel /fog/gparted/live/vmlinuz
initrd /fog/gparted/live/initrd.img
imgargs vmlinuz initrd=initrd.img boot=live union=aufs noswap noprompt vga=788 fetch=http://10.0.0.2/fog/filesystem.squashfs

Lets change the parameter block to look like this

kernel tftp://${fog-ip}/fog/gparted/live/vmlinuz
initrd tftp://${fog-ip}/fog/gparted/live/initrd.img
imgargs vmlinuz initrd=initrd.img boot=live union=aufs noswap noprompt vga=788 fetch=http://10.0.0.2/fog/filesystem.squashfs
boot || goto MENU

petec · Feb 23, 2022, 10:20 PM

@george1421 You helped a bunch my friend

i did some tweaking and now is works, here is the menu parameters for latest gparted:

kernel tftp://${fog-ip}/fog/gparted/live/vmlinuz
initrd tftp://${fog-ip}/fog/gparted/live/initrd.img
imgargs vmlinuz initrd=initrd.img boot=live config components union=overlay username=user noswap noeject vga=788 fetch=http://10.0.0.2/fog/filesystem.squashfs
boot || goto MENU
