I used to have an issue with some Realtek cards behaving weird and throwing errors in IPXE and later in the boot process, but it’s been a while. With these two HP models and an integrated Realtek card I had to use a different boot firmware, long shot but maybe you can try that?

HP210 Legacy Test

pxe-service=tag:HP210,X86PC, “HP-210 Working”, realtek.kpxe

HP430 UEFI Test

pxe-service=tag:HP430,X86-64_EFI, “HP 430”, realtek.efi

@lucycle said in NFS over TCP not available from x.x.x.x:

In my case the driver in question was dm9601.ko and I also compiled it into my initrd.img which did not fix the issue and behavior persists.

I’ve added another USB dongle, this time a Lenovo 2.0 Ethernet Adapter based on the asix driver, however it didn’t work, then I checked with modinfo and noticed I was missing a dependency (usbnet.ko)

modinfo asix
....
depends:        mii,usbnet

modinfo usbnet
filename:       /lib/modules/4.15.0-34-generic/kernel/drivers/net/usb/usbnet.ko

Just to be sure, you said initrd.img, I added it to initrd.lz

That’s about all I’ve got to suggest at this point

@george1421
Thanks george1421,
I have no issues with mine but thank you

Can you share your ltsp.conf ?
I have seen this as well if I don’t have this line in my confg

Here are the steps I’ve taken from a Live Ubuntu USB

I scp-ed the initrd.lz.new to the Fog server and renamed it to initrd.lz

I get an ip address but now I get a different error further down the track.

Not sure if because I just copied my Mint 18 Menu for Fog and adjusted it for Ubuntu hoping it would work
(ubuntu18 folder contains extracted files from the ISO)

Looks like there’s an issue with booting Ubuntu 18.04, I see another thread here that I’ve been following.

I’ve done the same process for mint 18.2 and that works without a problem, hopefully someone finds this useful

Hi everyone,
I’ve got an issue with certain network cards not being able to mount nfs and load Ubuntu 18 presumably because of the driver?

connect: Network is unreachable
NFS over TCP not available from x.x.x.x

It drops to an initramfs prompt and when I type ip add all I get is the loopback interface

(initramfs)ip add

1: lo: >LOOPBACK>

I have no problems with PXE booting PartedMagic over the same USB 3.0 adapter, but it’s not using nfs
I suspect it’s the driver in the Ubuntu 18 iso, more specifically initramfs

I downloaded r8152.53-2.10.0.tar.bz2
compiled and inserted the r8152.ko into the initrd.lz in the /lib/modules/4.15.0-29-generic/kernel/drivers/net/ethernet/realtek/ folder and uploaded the new initrd.lz back to the fog server but it didn’t work. Must be a step I’m missing. There is no insmod in the busybox so not sure what to try next

The reason I used the above r8152 is because when I boot from a live USB that’s what the network card is using and works fine.

Sorry I know this is not really a fog issue but rather ubuntu / driver I’d still like to know how to resolve if possible
Thanks

@sebastian-roth said in FOG server with dhcp client registration:

@Pikmin I don’t like guessing much so we should just take a look at the facts - the packets on the network that is. So get your client ready but don’t start it yet. Go to your FOG server and install tcpdump (sudo apt-get install tcpdump or sudo yum install tcpdump). Then run the following command and substitute x.x.x.x with the client’s IP address: tcpdump -w /tmp/boot_issue.pcap host x.x.x.x

Leave that command sitting there, boot up the client till it shows the error “Either DHCP failed or …”. Now stop tcpdump (Ctrl+c). Upload the generated file /tmp/boot_issue.pcap to your dropbox/google drive and post a link here or send me a private message if you don’t want to share this with the rest of the world.

I just went through the process of doing this when I discovered that after issuing spanning-tree portfast on all the interfaces it appears to be working now, so that’s the solution like in the other thread.
Thanks again for all your help george1421 and Sebastian Roth, I won’t forget the porfast setting ever again

@sebastian-roth said in FOG server with dhcp client registration:

@george1421 Though the // isn’t nice and might be confusing - that’s not an issue.

@Pikmin To me this sound very similar to what we had just a couple of days ago here: https://forums.fogproject.org/topic/11093/resgistration-issues (read through all of it and take a look at the pictures!
Try using a mini switch to connect between client and your network - see if that makes it work.

I was using a cisco switch with a default config, so no vlans, nothing, tried with a dumb tplink, same thing.
It does look very similar after seeing the pictures attached

Is it worth mentioning that I have a proxy server at work, so when I was originally configuring the fog and downloading packages I have a few exports for git, apt.conf and wgerc so I can get to the Internet.
None of these appear to be on the fogclient

I’ve manually registered the client from the web interface and tried to capture the image that way but same error when it tries to start
I wasn’t paying attention, from the web it failed because Windows wasn’t shutdown or hibernation, testing that now, it’s up to the Resizing Filesystem… so might work
I’d still like to know why it’s failing through quick registration so I will try and upload the pcap file

I’ve also enabled portfast on all the ports

@george1421 said in FOG server with dhcp client registration:

I did not ask this and I probably should have before now. What version of FOG are you using? The latest doesn’t tell us much of anything.

My bad,
1.5.0-RC-10
SVN Revision: 6080

@george1421
Thanks for that, yeah not quite sure what’s going on
It appears when I wget http://192.168.158/test.php it downloads a file even though it doesn’t exist and the file contents are that of index.php
I see a link in /var/www/fog pointing to /var/www/html/fog
Compared the 001-fog.conf from apache to that of a production server here and appear identical, other than having ssl on one and http on this test server
Will report back if I find anything
Why is it detecting a . in wget I wonder

@george1421 No worries at all

I thought the second / was a problem until I saw it elsewhere on the forum, appears to be normal, could be wrong.

In any case the Web server settings look exactly like yours

So the issue is not being able to get an ip address from the server but not being able to access index.php

When I try to wget http://192.168.158.68/fog/index.php it works from a Linux laptop fine but from the debug console in fog I can’t get to it
wget 192.168.158.68/index.php however does work

@george1421 server is 192.168.158.68 assigned statically
EDIT: I’ve picked the debug option and tried to get an ip manually which worked and I can ping 68

I was trying BIOS first, then I thought I try UEFI, same issue with both

I am using the internal adapter yes.

I get an ip address in Windows from the fog isc-dhcp-server

First time I configured fog I used a router address of 192.168.158.1 but since that ip isn’t valid I removed it, also not using dns since not connected to Internet after initial configuration
server ip 192.168.158.68
client range 192.168.158.100-254

Hey guys,
I’ve been tasked to create a fog server on a standalone local network which will be connected to an switch (no internet connectivity), I need the server to hand out dhcp leases so I can capture an image and then push out the image to multiple laptops.

I installed the latest fog on ubuntu 16.04 server and specified to use isc-dhcp-server and a range.

Seems to be okay but having issues with registering the host, when I pxe boot it I can get to the fog menu but quick register doesn’t work, appears to be because of Realtek PCIe GBE Network adapter.
Attempting to register … Failed
The laptop model is HP 430 G5
I’ve tried specifying the realtek.pxe and realtek.efi with UEFI boot but no luck
For testing I tried another model - HP Spectre and that one booted up fine with a Lenovo USB 2.0 Network Adapter

@george1421

Thanks for clearing stuff up with me. Appreciate it

Also looking at your log file snp.efi is being sent. If you used my config file it should have sent intel.efi (right not I’m not saying its right or wrong kernel for that system I’m just looking for the same as I told it).

My bad, I was trying something from your previous post, with the intel.efi setup same thing

Ah ok then your dhcp server is sending out info too and the client is getting confused. Do you have time to debug this so we can see exactly what’s going on?

You will need the pxe-service commands but lets understand what’s going on first.
The Windows DHCP Server is set to PXE Boot SCCM

Also note that without using the netmask in the range directive PXE boot doesn’t work

I also have ip helper on the switch so I can netboot from other vlans

I’ve tried that but didn’t work for me, it gets to the boot menu but doesn’t seem to know what to boot, so the menu counts down and nothing happens

@george1421
Hello, can you confirm that the following fields are meant to be enough to boot into UEFI, not the basic but advanced option
Set the boot file name based on the matching tag from the vendor class (above)
dhcp-boot=net:UEFI32,i386-efi/ipxe.efi,192.168.112.24
dhcp-boot=net:UEFI,ipxe.efi,192.168.112.24
dhcp-boot=net:UEFI64,ipxe.efi,192.168.112.24

They don’t appear to be enough in my case, once again pxe-service is needed but you say in the guide to remove it :
Adding (a bit more complex) UEFI support to the basic script
We’ll start with our basic configuration file again. Note: we removed the pxe-serivce entries we added previously.

This is what my config looks like now, I’ve added a match for HP 210 and have been testing stuff out, BIOS doesn’t work with this model: No configuration methods succeeded (http://ipxe.org/040ee119) I have added a BIOS menu that boots nothing (removed the undionly line) because it fails anyway.

I have a separate HP210 UEFI menu

HP210 UEFI Test

pxe-service=tag:HP210,X86-64_EFI, “HP-210”, ipxe.efi

when I push F8 I get two options HP-210 and Boot UEFI PXE-64
Without the pxe-service and only dhcp-boot options, the boot fails

It doesn’t appear to be an issue with not being able to boot UEFI rather ignoring the dhcp-boot fields.
Without the pxe-service=X86-64_EFI, “Boot UEFI PXE-64”, ipxe.efi, the boot fails

Hi everyone,
I’ve been following the wiki guide to set this up
https://wiki.fogproject.org/wiki/index.php?title=ProxyDHCP_with_dnsmasq

The basic script example works fine but when I try to follow the second example it stops working.

Adding (a bit more complex) UEFI support to the basic script
We’ll start with our basic configuration file again. Note: we removed the pxe-service entries we added previously.

Soon as I remove the pxe-service entries I cannot UEFI boot and the dhcp-boot option doesn’t seem to do anything:

Set the boot file name based on the matching tag from the vendor class (above)

dhcp-boot=net:UEFI32,i386-efi/ipxe.efi,192.168.112.24
dhcp-boot=net:UEFI,ipxe.efi,192.168.112.24
dhcp-boot=net:UEFI64,ipxe.efi,192.168.112.24

Can anyone tell me what I could be missing?

There are powerful matching rules in dnsmasq’s configuration syntax. Here is an example of how this could be used to distingush between BIOS and UEFI. Note: This will NOT work in proxy mode!!
dhcp-match=set:bios,60,PXEClient:Arch:00000
dhcp-boot=tag:bios,undionly.kpxe,x.x.x.x,x.x.x.x # x.x.x.x = TFTP/FOG server IP

Does that mean dhcp-boot will never work in an unmodifiable dnsmasq proxy setting?

I would like to specify options per model and it seems to be working but dhcp-service is required. Certain laptops can’t boot into legacy No configuration methods succeeded (http://ipxe.org/040ee119)
