      It’s most likely nothing to do with FOG as it’s not even getting to the point of requesting a file, from what I can see. That or the FOG Server doesn’t have tftp running?

      tftpd-hpa service shows running. I tried restarting it as well. Checked in fog’s web gui and the user and password listed for fog tftp are correct.

        @Scott-B FOG Tftp has nothing to do with tftp running or not.

        Can you tftp a file to the system? THE FOG_TFTP stuff in fogsettings of from the time where fog was using pure pxelinux.0 as the boot file. These options were what was used for kernel updates and pushing the task file to the server telling the host to boot. More or less these fields could now be erradicated entirely, but I still use them for kernel updating.

        Can you try this: manually?

        sudo service xinetd stop
        sleep 2
        sudo service xinetd start
        sleep 2
        sudo service tftpd-hpa stop
        sleep 2
        sudo service tftpd-hpa start
        

        Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG! Get in contact with me (chat bubble in the top right corner) if you want to join in.

        Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

          I get a “timeout occurred. connect request failed.” when I try to send a file manually. Same if I try to get a file as well.

            Maybe you upgraded the system as well. Possibly enabling the firewall??

              I can tftp a file directly from the server console so its at least running. The only firewall on the system is ufw (Uncomplicated Firewall) but its disabled on start and is not running on the system.

                @Scott-B Could you check on a non-VM machine if it works? I’m not overly familiar with VM but I do know VM’s can be weird with PXE sometimes, they’re particularily picky with what network adapter will work.

                  I’ve tried on both physical and vm devices.

                      Because you can get the files via TFTP from the local server, it’s firewall or network related. And you say the firewall is disabled so… it’s network related probably.

                      Could it be an IP conflict, for either this host or the fog server?

                      Do you have a network hub (as opposed to a switch)? You could use that to do a capture with wireshark on a test computer. you could also do a capture on the FOG server. To really figure out what is going on, we need to see what’s going across the lines.

                                You can safely ignore this. It’s just a notice and does not prevent the client from downloading binaries via TFTP! I guess this message in the log came up when you tried tftp from the server console, right?? Please try again from the server and remote and see when you get the message in the logs.

                                Other than that I am kind of lost with this. Have you double/triple checked the IP addresses? Are you able to ping both ways (client which you test tftp from and FOG server)??

                                  I was able to tftp a file from the console, I was trailing the syslog at the time and did not see the message again. I can ping both ways without issue.

                                    @Scott-B The idea with troubleshooting when you don’t know what’s going on is just to start trying stuff. A lot of stuff. Write down notes about what you tried and if it worked or not. And while your doing all these ‘things’, your looking for messages and clues anywhere and everywhere.

                                    Try a WOL.
                                    Try an image capture
                                    Try an image deploy
                                    Try a snapin
                                    Try pinging.
                                    Try a packet capture while you try to do an image deploy.
                                    Make sure the patch cable connections are snug on the server.
                                    Try a new patch cable.
                                    Is there a typo in your DHCP option 066 or 067 ???
                                    Install FOG with DHCP, then take it off the network and connect it to just a mini-switch / hub, and then connect a target host to that and try imaging. Does it work?

                                        Ok, we did a tcpdump session on the FOG server and we see that the TFTP request from the client as well as the first TFTP answer packet leaving the server (but probably never making it to the client). While ping is working!! So the only two things (more or less one really) I can think of is access rules on the switches or firewall rules on the VM host (test client is running on a VWware host)… definitely not a FOG issue.

                                          With a lot of help from @Sebastian-Roth we did track down the issue. Someone must have been in our DHCP server and changed the case of the undionly.kpxe to all caps… thus not finding the file. Sometimes is those simple things you just don’t think to look for. Thanks again for your help Sebastian!

                                            You are welcome! 🙂 As well I learned to pay even more attention to what I see in the PCAP file. Would have saved us at least an hour or two… When testing with the command line client Scott didn’t know about the important -i option for Windows tftp command line client as described here. When looking at the PCAP file Scott sent me I didn’t notice that it tried to request the file in ‘netascii’ mode instead of ‘binary’.

                                            So everything is working now and it was just the upper case filename option in the DHCP config…
