Hello, I am attempting to setup a PXE setup for a network using multiple subnets. The current layout has dhcp on one subnet (10.16.215.8/30), tftp on another (10.16.194.0/23), and the system to be installed on yet another subnet ( 10.16.233.0/24 [there's actually about 30 different subnets the system to be installed could be on]). When I have the system to be installed on the same subnet as

Hi, I've been looking at the pxelinux code and I was wondering a couple of things: 1) Why does pxelinux create UDP packets from scratch instead of use the Intel PXE TFTP OPEN/CLOSE/READ calls? I'm assuming this is to support TFTP options like tsize right? Did earlier versions of pxelinux use the TFTP calls directly? 2) How big of an image can pxelinux download (minus memory

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:

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

I'm trying to network-boot a GCT Allwell set-top box without success. My frustration level is high. The problem seems to be that the Allwell is sending a RRQ with an option. tftp-hpa responds with an OACK, and waits for the corresponding ACK from the Allwell. The Allwell never sends that ACK, but instead continues with the same RRQ until timeout. Having read RFC1782, this makes me think

Once upon a time, Steven Tardy <sjt5atra at gmail.com> said: > The ?ICMP unreachable? should be a dead giveaway. . . You cut out the part of the email where the OP said that the UEFI system was ignoring the next-server part of the DHCP reply and trying to TFTP to the DHCP server instead of the TFTP server. Of course that got ICMP unreachable, but it isn't a firewall problem. 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

I apologize if this is the wrong place to be asking this, but I'm pretty much out of options on where to go. I'm using the pxelinux version of tftp. Everything has worked well up to this point, however I've been trying to impliment a pxe bartpe solution in our office. Unfortunatly tftp is not passing the files correctly to the client. Here's the rundown. Server client connects to

Hi, I am using a Windows Server 2012 R2 Hyper-V Generation 2 VM as a PXE client (no physical machines available). This is a UEFI VM, and as per instructions I've read I have disabled secure boot on this VM for the installation of Linux. I am using the latest tftp-hpa package with the following config: # /etc/default/tftpd-hpa TFTP_USERNAME="tftp"

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
