Much thanks, George and others for the help. As well as saving my company thousands of dollars! :)

@george1421 I tested that earlier. It works.

Okay, I managed to upload a PCAP from Wireshark:

Wireshark Capture

After much frustration, I set up another Fog installation on Ubuntu that is working much better. I still get a “TFTP open timeout” but at least I can transfer TFTP in both Windows and on the Fog server.

So there’s something wrong with my CentOS install. I reinstalled it twice and followed the Wiki instructions to the T.

@george1421 Where is the output.pcap file saved?

@Sebastian-Roth Here’s the output of my iptables:

Chain INPUT (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination

Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination

@Sebastian-Roth I disabled firewalld in CentOS.

@george1421 Edit: Misread the question.

Everything is on the same subnet. We’re on a .23 subnet. In fact all the devices I’m using for testing are plugged into the same switch.

I’ll work on getting the info you need.

@Sebastian-Roth Same error in Windows tftp test with firewall disabled. Its not an access denied so I’m fairly confident its not a firewall issue. I’m getting this on a VM and physical hardware install of CentOS 7.

Very strange. I even rebooted after the change for good measure.

@Sebastian-Roth Attached is output.

Just for good measure, I tore out the VirtualBox solution and stood FOG up on an old desktop. Same error.

I even ran tftp -i <ip> get udionly.kpxe

connect request failed

Same problem with legacy BIOS and UEFI. I can ping the FOG server from my client machine, but FOG can’t ping client.

@Sebastian-Roth

VirtualBox is running on a Windows 10 PC and is setup in Bridge mode. I had some networking issues due to an aggressive web filter on our network, but other than that, this has been functioning normally.

Please disregard the fact that I couldn’t ping anything from the server. I can’t ping them from other machines from the host either. So I’m not pursuing that path right now.

I did view the TFTP troubleshooting page and I checked everything there with no success.

Okay, sorry about the spam as I’m troubleshooting in parallel with providing you with more information. I’m running Fog in a CentOS VM running in Virtualbox which is running on a Windows 10 host. So I may be running into Windows firewall issues. I cannot ping external machines on the network from CentOS.

@Sebastian-Roth said in TFTP Open Timeout on New Fog Install:

ipxe.efi

Error message attached.

@Sebastian-Roth Netstat returns this:

udp 0 0 0.0.0.0:69 0.0.0.0:* 3332/xinetd

@george1421 3 years and one company! LOL. Also did that in a VMWare environment. Lots of differences this time!

Prior to this role I installed Fog 0.32 and didn’t have as much issues as I’m having with this latest version. I’m unable to connect to the FOG tftp when booting from the network interface. I get the error “TFTP Open Timeout” on my Lenovo X1 Carbon and my VMWare Workstation VM pulls a DHCP address and just fails to the BIOS.

I admit that I had the wrong IP address in the option 66, noticed it right away and updated the IP address but machines still fail with the same error. Option 67 is set to undionly.kpxe like it’s supposed to. Both clients still failing.

My DHCP server is a Meraki MX100.

@fhrivers That did it. I assumed that since I could browse this site, I didn’t need to add it to the web filter. I’m up and running! Thanks!

@Tom-Elliott Yes, we’re blocking freeware and shareware sites but I haven’t had any problems getting to the site. But I’ll add it to the webfilter anyways.

@Sebastian-Roth said in CentOS 7: Could not download init.xz properly, FOG will not install:

https://fogproject.org/inits/init.xz

Also, it seems as if the stuff from the Github url loads fine. I can’t load anything from the fogproject url. In fact when I paste the fogproject url in my browser I get an error too.
