I had the same issue. For me, the problem was solved by manually creating the fog database and the fog user, and then rerunning the installer. We have a few fog servers and have always used the same mysql password, which is not blank. I don’t know if that’s what caused the failure of the db creation, but I figured I’d mention it, since the default suggestion on the installer is to use a blank password. Also, we are trying to use https, so I ran the installer with the “-S” option.

I hope this solves your issue - though given the recommendation from the developers to use trunk, it’s probably best to do that.

@george1421

Cool - I’m glad it’s working for you - there’s hope! What is your OS for FOG (and dnsmasq)? Are you using the simplified ltsp.conf file you posted previously?

Is your Virtualbox 5.1.10? Were there any options in VirtualBox you had so specify (that I might have missed)?

Here’s the logs from the fog server when the VM is netbooted:

@Sebastian-Roth

VMs are still not able to continue the netboot process with the additional specification of the fog server IP. I just used the IP address twice, as this fog server is not available vi dns (so I didn’t use the name).

Thanks for the suggestions though.

@george1421

I tried the simplified ltsp.conf file you referred me, but that also does not work.

Thanks again,
Marc

@george1421

Here’s the anonymized pcap. Hopefully it still provides all the relevant information you need.0_1480964109034_output_anon.pcapng

@george1421

I had tried to display everything I saw when I opened it up in Wireshark, but maybe I missed something.

There’s some information in the pcap that I can’t seem to scrup. I found an app called tracewrangler that I’ll try to work with to prepare the pcap file.

Thanks again,

Marc

@Sebastian-Roth said in virtualbox client can't netboot pxe-e74 Bad or missing PXE menu and/or prompt information:

This somehow sounds as if virtualbox client is not happy with option 43 being sent by dnsmasq in frame number 3. Quiet strange I find. Can you please post your dnsmasq config? Maybe try stripping options pxe-service and/or pxe-prompt from it - if set.

I have 2 lines with that specify pxe-service options and tried commenting them both out. I also commented out pxe-prompt. None of these changes to my ltsp.conf file allowed the VM to netboot.

I’ll attach the ltsp.conf file here.0_1480949862710_ltsp.conf

Thanks for your help.

@george1421 said in virtualbox client can't netboot pxe-e74 Bad or missing PXE menu and/or prompt information:

@MarcB Is your target machine, dnsmasq server, and dhcp server on the same subnet (broadcast domain). If so then we should probably get a pcap file of of this pxe boot to error message.

1. install tcpdump on your fog server
2. start tcpdump with this command line at the fog console prompt tcpdump -w output.pcap port 67 or port 68 or port 69 or port 4011
3. then pxe boot the target computer (vm) to error
4. once at the pxe error press ctrl-c to stop tcpdump
5. post it here for review.

This will tell us what your dhcp server/dnsmasq server/ and what your client is asking of the tftp server.

Thanks again for your help with this issue.

I thought I should add that, with the exception of bridged networking, all other settings for virtualbox client are the default settings for an ubuntu 64-bit install.

Here’s the output file of the tcpdump command (run as sudo):

Oh, and for the record our fog server is a physical box (non-vm). The only VM in question is the one I’m trying to boot from the fog server.

The VM is definitely bridged, and is getting an address on the appropriate network. The Oracle VM VirtualBox Extension Pack shows up in Preferences as “Active” and is the same version as the Virtualbox Software app.

As I said earlier, non-virtual machines get an address from our dhcp server, and are directed to the FOG server by dnsmasq. Here’s the logging that takes place as the VM tries to boot (I’m hitting “F12” when the machine boots).

Server

• FOG Version: 1.2.0, not serving dhcp, but using dnsmasq. Works fine with non-virtual client machines.
• OS: ubuntu 14.04.5

Client

Virtualbox

Description

Virtualbox starts, gets a dhcp address from the cisco switch, but doesn’t seem to get more info fog server. Error is: pxe-e74 Bad or missing PXE menu and/or prompt information

Okay - I found the error. I had created a copy of ltsp.conf in dnsmasq.d and renamed it ltsp.conf.server2. I scp’d it to server2 there, but it was still in the /etc/dnsmasq.d. I just reread the README and see that every file in that directory will be read by dnsmasq unless it has “.dpkg-dist”,“.dpkg-old” or “.dpkg-new” appended to the end.

I (incorrectly) figured that renaming the file would keep it from being read.

Thanks for your help, and for your great, great product!

More looking at logs on server1 revealed several instances of this:

Sep 8 07:17:31 Server1 dnsmasq-dhcp[1160]: DHCP, proxy on subnet 10.95.0.45
Sep 8 07:17:31 Server1 dnsmasq-dhcp[1160]: DHCP, proxy on subnet 10.105.0.45

This makes me think that server1 is indeed the one that’s screwed up, and is telling pxe clients to boot to the server in the building2.

I know this is a crazy problem to track down, as there were so many changes. I’d like to mention that server1 has worked great for years, and that server2 worked in building2, and allowed me to the image the machine there that I needed to.

@Tom-Elliott

Here’s /tftp/default.ipxe on server1 (it contains the address of server1):
#!ipxe
cpuid --ext 29 && set arch x86_64 || set arch i386
params
param mac0 ${net0/mac}
param arch ${arch}
isset ${net1/mac} && param mac1 ${net1/mac} || goto bootme
isset ${net2/mac} && param mac2 ${net2/mac} || goto bootme
:bootme
chain http://10.105.0.45/fog/service/ipxe/boot.php##params

=======

And here’s the same file from Server2 (it contains the correct address for Server2):

#!ipxe
cpuid --ext 29 && set arch x86_64 || set arch i386
params
param mac0 ${net0/mac}
param arch ${arch}
isset ${net1/mac} && param mac1 ${net1/mac} || goto bootme
isset ${net2/mac} && param mac2 ${net2/mac} || goto bootme
:bootme
chain http://10.95.0.45/fog/service/ipxe/boot.php##params

=====================================================

@Wayne-Workman Well, I wondered about that, so I disabled the port on the switch that connects server2 to the network. When I did that, that machine hung when trying to pxeboot and I got an error something like file not found (can’t recall the exact wording, but was the kind of error I received when tftp server wasn’t working).

At one point I did have the wrong broadcast entry in the interface file of server2. The IP address, gateway, subnet mask correctly specified the network for building2, but the broadcast entry was for building1. I fixed that, and restarted the server, etc. Could that info be lingering in the network somehow? How could tell?

It occurs to me now, after hunting around some more that I could perhaps achieve what I want simply by following the directions used to change an IP address. In my case, I wouldn’t even need to change fog .settings file, but would just need to rerun the installer.

Thoughts?

Hey Folks,

I was creating an additional FOG server for another building, and after I got FOG installed on it, I copied over my ltsp.conf file to the 2nd server. I also copied the undionly.kpxe to undionly.0 (rather than symlinking them).

Somehow I must have messed up the boot kernels in my original FOG server, because machines that pxe boot in this network now actually try to register with the FOG server in the other building! My hunch is that I copied undionly.kpxe from server2 over to server1 by mistake, rather than copying it to undionly.0 on the same server.

Server1 is on the 10.105.0.0 network, and Server2 is on 10.95.0.0 network.

Here’s what I see in syslog, when I grep for dnsmasq:

Sep 8 16:25:31 server1 dnsmasq-dhcp[1088]: 3451364178 available DHCP subnet: 10.105.0.45/255.255.0.0
Sep 8 16:25:31 server1 dnsmasq-dhcp[1088]: 3451364178 vendor class: PXEClient:Arch:00000:UNDI:002001
Sep 8 16:25:31 server1 dnsmasq-dhcp[1088]: 3451364178 PXE(eth0) 78:2b:cb:b7:a3:52 proxy
Sep 8 16:25:31 server1 dnsmasq-dhcp[1088]: 3451364178 tags: eth0
Sep 8 16:25:31 server1 dnsmasq-dhcp[1088]: 3451364178 bootfile name: undionly.kpxe
Sep 8 16:25:31 server1 dnsmasq-dhcp[1088]: 3451364178 next server: 10.95.0.45

Given the above, I’m thinking that I need to regenerate (or edit) my undionly.kpxe and undionly.0 files on Server1, as I assume that that’s the one that is telling my pxe booted clients where to find the next server.

If I’m barking up the wrong tree, please where else I should be looking. My ltsp.conf files on Server1 and Server2 both look good.

Thanks a lot in advance!

M

@Wayne-Workman Are you referring to this line:
pxe-service=X86PC, “Boot from network”, undionly

I had that line uncommented as well, and still had the issue where my machines were not finding their hard drives. This issue cropped up once I installed dnsmasq. Everything else about FOG process on these very same machines worked flawlessly (and had been since v.28).

The one change that allowed them to find their hard drives was uncommenting the line:
pxe-service=X86PC, “Boot from local hard disk”, 0

@Tom-Elliott Thanks Tom - yes, that option was commented, and that fixed my dns issue on the fog server (dns broke when I installed dnsmasq, but was restored by commenting out that line). Buy my machines wouldn’t find their hard drives unless I uncommented the line I specified above.

Hey Gang,

I had a working FOG 1.20 server running on ubuntu 14.04 for a while, but then decided to run dhcp from our cisco equipment. I followed the instructions for installing dnsmasq, and got everything to work regarding pxe booting. However, if I didn’t select any pxe boot options (register host, etc), and allowed the system to boot from hard drive, it would fail indicating no startup disk, and would suggest pressing F2 for setup, etc. This was a different behavior from other folks (various posts in the forum) who had a black screen and a flashing cursor in the corner.

I solved the issue by editing /etc/dnsmasq.d/ltsp.conf and uncommenting the line that reads:

pxe-service=X86PC, “Boot from local hard disk”, 0

For the record, I created my ltsp.conf file from the sample provided in the documentation, and just changed the relevant parts (server IP address, etc), and kept everything else as is.

Anyway - I thought I’d post this in the hope that someone else who may be struggling with this issue will find success with this solution.

Keep up the good work on this excellent project! FOG is one of the greatest tools I’ve ever used in my 16 years as a sysadmin.

Thanks,

Marc
