Cant PXE Boot = PXE-T01: File not Found

Sebastian Roth

@404 As you can see in Wayne’s message signature he’s got an automatic test environment that does daily installs on several different distros/versions (including debian 9) and we don’t see any issue there at the moment. If you are still keen to find the issue please post your install logs here.

For the other things like “what can FOG do/don’t do” I’d ask you to open a new thread and ask your specific questions. We try to keep things sorted a bit here so other people can follow if they have the same issue. For those people it’s not helpful if several different issues are being discussed in one thread.

@Sebastian-Roth Ok, i get your point. Sorry about that.

Could you tell me where i find those install logs. I would love to share them and find a solution

Thank you.

Sebastian Roth

@404 No worries. Just trying to keep things a bit sorted.

In the same directory where you have the installfog.sh script a subdirectory error_logs/ is created… you should find two log files there. Upload both and we’ll have a look.

404

ok, here we go

https://mega.nz/#!5EgC1RZZ!BOfPySnN9QyL40H4bqTTVe9vPoRQsIJ7T-DGrO_QcrY
https://mega.nz/#!8MwRiRAK!-lx9bMjRzG0_EwoPixuhxcm9bjdOoZ5JD77QEjDCGQk

I couldn’t upload my files here directly to the forum so i just put them up on mega.nz

Thanks for your help

Moved this to bugs, because I confirmed the problem in master branch.

@Sebastian-Roth I just tried doing an install on Debian9 with 1.4.4. If you specify the installer to setup dhcp, it fails when trying to start the dhcp server. And because the /tftpboot directory is setup after dhcp is, that doesn’t get done.

I’ve been digging into the problem, it’s IPv6 related as far as I can see right now. Here’s the error:
Starting ISC DHCPv6 server: dhcpd6check syslog for diagnostics. ... failed!

Figured it out. In Debian 9, you have to put the interface name into this file:
/etc/default/isc-dhcp-server

When I looked at mine, it looked like this:

INTERFACESv4=""
INTERFACESv6=""

So I changed it to read like this:

INTERFACESv4="ens3"
INTERFACESv6=""

Then I had to remove the pid file:
rm -f /var/run/dhcpd.pid

Then, I could finally start the dhcp service:
systemctl start isc-dhcp-server

404

@wayne-workman ok perfect, thanks for your fast reaction. I will give it a try…
So this way it should only start the DHCPv4 and ignore the v6 stuff, right?

I will try to install the isc-dhcp-server first and set this up. Then i will run the installfog.sh an see what happens

Thanks

Wayne Workman

@404 Well, what I’d suggest for now is to run the fog installer as normal. After it fails, go edit that one file, delete the pid file, then re-run the installer again. It should succeed the second time. FOG has to carefully configure the dhcp server so that multiple architectures are supported. We’re going to write a patch here shortly to fix this in working branch.

Sebastian Roth

@wayne-workman Thanks heaps for looking into this! Reading through a couple of old posts on the internet I kind of came to the same conclusion that it’s an issue with a missing/wrong /etc/default/isc-dhcp-server parameter.

Hmmmm, I am wondering how we are going to fix this. Why is it working in debian 8? I’d actually expect debian (dpkg) to generate /etc/default/isc-dhcp-server properly!

Wayne Workman

@sebastian-roth said in Cant PXE Boot = PXE-T01: File not Found:

Hmmmm, I am wondering how we are going to fix this.

Maybe a sed command that uses a variable. This would only match if it’s empty:

interface="ens3"
sed -i "s/INTERFACESv4=\"\"/INTERFACESv4=\"$interface\"/g" /etc/default/isc-dhcp-server

Sebastian Roth

@Wayne-Workman Yeah sure we can just force it. But I am wondering why this is the case. Searching more I found this: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=815319

So the issue has been around for a fair bit of time. But I still haven’t figured out if this is just an issue with the debian specific start scripts or if it’s actually a newer isc-dhcp-server version doing the env variable check… then fails if it’s not set - very poor I find.

Sebastian Roth

Interesting… the bug report just posted ends with stating that this is fixed in version 4.3.5-1. In the logs posted I see version 4.3.5-3 being installed. Possibly a regression?

Edit: Here we go I think: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=862680

Although I really like debian I am still not sure if this is something we should fix. Maybe we do and next time debian is doing something different again…?!

Wayne Workman

This is a pretty simple fix, so I don’t see why not. If the debian team fixes it later, great. When they fix it, the sed command will stop matching. just my opinion. I think we should make the installer work on the mainstream distributions - even with their problems to an extent.

Sebastian Roth

Seems like the newer isc-dhcp-server version does start as IPv4 and IPv6 DHCP server if no interface is given in /etc/defaults/isc-dhcp-server. As we don’t have any IPv6 definition in our config it fails to start. One way to fix this would be to add IPv6 defintion but as I don’t think this will be of much use to any of our FOG users I’d better follow Wayne’s idea on fixing /etc/defaults/isc-dhcp-server.

Fix is pushed in working branch. So here is another reason to push for the next release.
