UNSOLVED PXE Timeout issue
Tue Nov 01, 2016 14:44 pm
Running Version 1.3.0-RC-14
SVN Revision: 5974
- Service Version: N/A
- OS: Windows 7
Ok so this is a simple network a Fog server set up with a switch one client PC and one other PC to get to the GUI.
For the actual problem now it seems that when I initially set up the server it will work until I reboot it or shut it off then the clients PCs/hosts can not get a PXE Request from the Fog. But (please note it was working with no problem before the restart.)![0_1478014376308_20161101_112330.jpg](Uploading 100%)

George is correct in what he’s said here. If this is a simple isolated network with one switch, two clients, and a fog server - then the FOG server just isn’t running DHCP as it should be. You can check if the service is running or not with
service dhcpd statusand you can try to start it with
service dhcpd starton Ubuntu 14. Your configuration file will be at
/etc/dhcpd/dhcpd.confIf you told the FOG installer to do DHCP, the fog installer would have built this file for you and configured DHCP too, and enabled it and started it as well. I can test that this is working properly on Ubuntu when I have some time. I can say that it works just fine with CentOS 7, I’ve not tried DHCP via FOG on the other major distributions in a few months but I don’t think any of that code has changed much.
@george1421 lol Well thank you for the Laugh but I will try that and see if that resolves it.
@JTech I can’t answer that. I use to do mind reading. But I sucked at it so I had to give it up for a paying job in IT.
Your original message and error was that the target computer did not receive a response from a dhcp server. Meaning that there is no dhcp server on your network with the FOG server, switch, and target computer.
@george1421 but why would it work correctly before and suddenly change
@JTech ok then you need to read through that link I provided for 14.04 because it sounds like dhcp isn’t properly configured on you ubuntu server. So that is why your target computer isn’t pxe booting. You haven’t even got to the FOG bits yet.
@george1421 nope it looks the same way 0.0.0.0.0.0.:51667 0.0.0.0:*
@JTech same command again. you want this line in the netstat
udp 0 0 0.0.0.0:67 0.0.0.0:*
@george1421 it says ok in Green
this is for 14.04 but the format should be the same:
@JTech ok that tells me that your dhcp server is not running.
sudo /etc/init.d/isc-dhcp-server restart
@JTech wow, not useful…
You should use the netstat command I provided below
netstat -an | grep 67or
netstat -an | grep 68
You are looking for a line like this:
udp 0 0 0.0.0.0:67 0.0.0.0:*
@JTech the netstat command will show you if something is bound to the dhcp port 67
Also this wiki page will be useful when you get to having both bios and uefi systems on your campus.
@george1421 do you know and easy command to tell if the service is running
I can say from you ubuntu server if you key in
netstat -an | grep 67it should return something if ics-dhcp is running. Or any dhcp server on that server.
@JTech ok this setup was done with ubuntu and not via FOG install?
Then you need to see if dhcp services is running on ubuntu. (sorry I’m a rhel guy).
When I set the Ubuntu up it asked if I wanted to use there DCHP server so I would say the Ubuntu DCHP service

@george1421 I’m going to further guess DNSMasq was being setup but the “on boot” establishment wasn’t performed?
