similar to: syslinux.efi pxeboot across multiple subnets

Hi Guys, i have a problem with PXE/UEFI Boot. Legacy PXE Boot is working fine. I use Dnsmasq with integrated tftp. As Mentioned above, legacy pxe boot is working fine, tcpdump shows: --- start tcpdump legacy pxe boot --- 13:44:16.589197 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from f8:ca:b8:06:7d:ed (oui Unknown), length 548 13:44:20.543910 IP 0.0.0.0.bootpc >

Hi Everyone, I'm trying to get an asus motherboard to netboot. It has an integrated Nvidia boot agent that's supposed to network boot pxe happily. I've setup the necessary services and environments in tftpd, however, the boot agent is running into trouble requesting files from the tftp server. It always seems to receive File Not Found errors. The filenames are specified properly

Good Afternoon, As per the installation guide, section 30.2.2 I?ve created an efidefault file at /var/lib/tftpboot/pxelinux/pxelinux.cfg/efidefault However, this file is never requested by the 64 bit PXE loader (bootx64.efi), as shown by tcpdump: 75 RRQ "/pxelinux/42272635-0011-5053-ACF2-82A100E615F2" octet tsize 0 blksize 512 59 RRQ "/pxelinux/01-00-50-56-A7-BA-BF"

H Peter, I notice the Intel Boot Agent (in the BOOT ROM) takes a different approach. When TFTP loading the initial syslinux.efi. It receives the OACK with both options set -- tsize (of 145744) and blksize (of 1408). Apparently it has challenges parsing this "two option" OACK packet. But it remembers the tsize of 145744. So it issues another read request, this time requesting only a

Gene and co, Now my pxelinux efi 64 boot is properly loading syslinux.efi (via TFTP) It then issues a TFTP file request for efi.x64/pxelinux.cfg/ldlinux.e64. (All my efi x64 content is under efi.x64/pxelinux.cfg). However, I see that it fails to properly negotiate the TFTP options with my TFTP server. so it never transfers ldlinux.e64 over. In its file request packet, it asks for these TFTP

The setup I was using was in a chassis. Slot 8 of the chassis is the client machine. It goes through Switch 1 (a Brocade switch) to the top of rack (BNT). The mirror is in the chassis switch. Slot 3 of the same chassis is connected to the mirror port in Switch 1. client = 1/0/8 tcpdump = 1/0/3 to TOR = 1/0/43 1/0/8 mirrored both directions to 1/0/3 Unfortunately, I don't have access to the

Hello, I am seeing sporadic duplicate read requests from lpxelinux.0 (6.03 from kernel.org), which results in a failed PXE boot. This happens only sporadic, but happens often enough to be annoying. The TFTP server serving lpxelinux.0 is running CentOS 7.6 with all updates applied. The client machine initiates the PXE boot, receives the lpxelinux.0 binary, downloads ldlinux.c32 and proceeds to

Hello list, We have a scenario where our TFTP server is not the same IP as our DHCP server. While testing with 6.03, our setup works just fine. However with the master branch, for some reason pxelinux.0 is fetched from the TFTP servers IP, but then it tries to load ldlinux.c32 from the DHCP servers IP. I've tracked down this problem to the following commit:

Hello, I am attempting pxelinux via dhcpd/tftpd. If I use the system default tftpd daemon, then pxelinux loads but then complains about the tsize option. I've downloaded tftp-hpa-0.34, compiled and installed. I also edited inetd.conf according to README.security and then reloaded inetd. /tftpboot directory and all files and directories have nobody:nobody for permissions with at least read

Hello, I tried to boot the new syslinux.efi (32bit) from the released syslinux 6 via PXE. In a wireshark trace I can see that the syslinux.efi was loaded successfully via TFTP. Then the client try to load ldlinux.e32. I see the request and also the acknoledgement in the trace. After that the client try to load the file, but the source port is changed to tftp request port + 1. For example:
