    Server

    Client
    • Service Version: latest
    • OS: windows 7
    Description

    Hello,

    Since the release RC13, the network boot doesn’t works anymore. All of my client request the IP of the TFTP server. It does not work even if i put the ip.

    Every PC are stuck at boot because their are all programmed to boot on network. I’ve got this :

    Configuring (net0 00:11:22:33:44:55)...... OK
    Received DHCP answer on interface net0
    Please enter TFTP server
    

    My installation is new, i did not use the backup file yet.
    I didn’t have this problem with previous versions (1.2, 1.3 RC6-11)

        Normally we see this error if there’s multiple DHCP servers trying to hand out conflicting information. The fact that you’re stating that entering the FOG Server IP as the next-server (the IP to the tftp server) is not working, I would venture that these systems are getting IP’s outside of the scope of the network that the FOG Server is residing on.

        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 have a server (Windows Server 2012 R2) for DHCP management. OF course, i refused that fog handle the DHCP at the installation. All of my machines are on the same range (172.16.X.X/16) even Fog and DHCP server. Options 66 & 67 are correct too, if i remove them, the PXE process is exiting.

            @educapole Nothing changed between 1.3 RC 11 and 1.3 RC 13 in regards to ipxe booting.

              @educapole said in FOG 1.3RC13 TFTP error:

              All of my client request the IP of the TFTP server.

              This means you have another DHCP service operating on your network somewhere which isn’t configured correctly for fog. It could be a switch, a router someone hooked up wrong in their room, or a new server or something.

              This is the case every time.

              Run wireshark on your computer and do some IP release / renews. Use the bootp filter. You’ll see multiple replies for DHCP, one or more of them will be the other DHCP service.

                Actually I’d like to see a pcap from the point of view of the FOG server as long as the fog server, dhcp server and target computer is on the same subnet. I would have the OP run the tcpdump program (which may need to be installed) with a command like. tcpdump -w output.pcap port 67 or port 68 or port 69 or port 4011 Then pxe boot the target computer, once the target computer reaches the error (or question in this case) press control-C on the tcpdump program. From there upload the pcap to this forum so we can look at it.

                    Bingo!! and those dang wifi access points with built in dhcp will point to them selves as the next hop server so the clients will try to download the boot image from them.

                    Good find.
