It has worked fine in the past.

It turns out it works when I set up the FOG server as dhcp server, connect it to a switch that is not connected to anything else, and then try to boot.

A network problem of some sort.
Very weird indeed.

Hi.
I’m having this weird problem with PXE booting.
My setup:
192.168.100.1 FreeBSD firewall (pfSense)
192.168.100.3 FOG Server
192.168.100.4 Windows domain controller

The FreeBSD firewall is the DHCP server.
I have the next-server and filename option in the config file:
[CODE] next-server 192.168.100.3;
filename “pxelinux.0”;
[/CODE]

When I try to boot, I get an IP-adress, but I get an error when it tries to download the pxelinux.0 file:
[CODE]
PXE-T01: FIle not found
PXE-E3B: TFTP Error - File Not found
PXE-M05: Exiting Broadcom PXE ROM.
[/CODE]

I am running wireshark on the FOG Server console, and I get no traffic on port 69 when I try booting.
If i try to download manually with a tftp client, the file gets transferred, and wireshark shows the request in my console.
[CODE]
root@imageserver:/tftpboot# tshark -f “host 192.168.100.101 or port 69 or host 192.168.100.1”
Running as user “root” and group “root”. This could be dangerous.

Here’s when I try to read file manually with a tftp client.
[CODE]
132.184676 192.168.100.4 -> 192.168.100.3 TFTP Read Request, File: pxelinux.0\000, Transfer type: octet\000
[/CODE]

Can’t figure out whats wrong here.

Help appreciated.
