Cant PXE Boot = PXE-T01: File not Found

404 · Dec 30, 2017, 3:16 PM

@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 · Dec 30, 2017, 4:47 PM

@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.

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 · Dec 30, 2017, 8:39 PM

@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 · Dec 30, 2017, 2:41 PM

@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 · Dec 30, 2017, 8:58 PM

@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 · Dec 30, 2017, 9:04 PM

@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 · Dec 30, 2017, 3:11 PM

@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 · Dec 30, 2017, 3:18 PM

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 · Dec 30, 2017, 10:03 PM

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 · Jan 2, 2018, 3:49 PM

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.
