    Ipxe will show initializing devices and then a very brief glimpse of where it typically shows all supported ipxe “processes” ie HTTP and so on.

    The systemctl status httpd shows over 4500 connections, but I only have the client on about 590 machines. I believe it’s getting timed out due to the large number of connections, but this is only a guess.

          What do you see in apache error and access log when trying PXE boot?

          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)

                  @Hanz Well, without an error message or any other hints we won’t be able to help!

                  Try capturing DHCP and TFTP traffic on the server while booting one particular client. Please make sure only one client is booting at that time so the packet dump won’t be several MB big. Install package tcpdump and then:

                  tcpdump -i eth0 -w pxe.pcap port 67 or port 68 or port 69

                  Leave it there and PXE boot the client. After it failed stop tcpdump (Ctrl-c) and upload the PCAP file.

                  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)

                        @Tom-Elliott Seams like the current undionly.kpxe binary (possibly also the other iPXE binaries too) is corrupt. Can you update again. Don’t think this is related to the script change (proxydhcp) as it completely crashes in my test QEMU setup. Script error wouldn’t crash I suppose.

                          I also saw this issue but couldn’t trouble shoot as I needed it up for production I also didn’t see anything weird in the logs. Right now I’m reverted to 4978.

                            I just tested and you are correct, something is corrupt/not right at all. I just did a test upload using the latest svn and it failed exactly as described here:

                              PXE Booting should be fixed.

                              We had a bad caller in the ipxe script.

                              Particularly, the code segment:

                              ...
isset(${proxydhcp/next-server}) && set next-server ${proxydhcp/next-server}
...

                              It doesn’t fail out propery (releases back to BIOS if you will) if the proxydhcp/next-server variable is not set. The fix was simple, just make the segment as:

                              ...
isset(${proxydhcp/next-server}) && set next-server ${proxydhcp/next-server} ||
...

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!
