It seems that tftpd-hpa is more suitable at serving arbitrarily large files (greater than 65535 blocks long; with pxelinux.0 using a default block size of 1408 this is 92,273,280 bytes) as atftpd will complain in the log stating "Requested file to big, increase BLKSIZE". I saw that a while back HPA mentioned that atftpd was probably more scalable (number of clients) while tftpd-hpa is

Hi, I've been struggling with this problem for the last couple of hours and am nowhere near solving the problem. I am trying to run a tftp server in a chroot jail. Now perhaps I am being paranoid, but I would like to have it launched from within its own jail even if it supposedly does a chroot itself and runs with a parameterizable user. I downloaded the atftp-server package and tried

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

I'm trying to network boot a thin client using pxelinux. I had this working about a year ago but have since reinstalled my OS (went from RH9 to FC2). I'm using atftpd. The thin client gets the dhcp address fine and requests pxelinux.0. Eventually, it just times out. Here's the relevant info from /var/log/messages: Oct 7 23:14:36 home atftpd[4717]: Advanced Trivial FTP server started

After the PXE PROM code downloads and runs the pxelinux.0 image and it tries to download config information the client stops acknowledging the server OACK packets from the server. pxelinux from syslinux 3.11 from Fedora RPM, accessing Solaris 10 in.tftpd The tftp client in pxelinux.0 sends a tftp file read request with extended options tsize \00 0 \00 blksize \00 1440 \00 and then the server

Hello, we have a problem with pxelinux and a specific hardware. In short: PXE starts, get and start the pxelinux.0 but can't get the configuration file. This problem belongs only to one new client. Other clients work in this environment with out any problem. The client is a HP xw4300 with the networkcard: ------------ vendor = "Broadcom Corporation" name = "NetXtreme BCM5752

Hi, i'm trying to get my VIA Epia with VIA Rhine ethernet device to boot PXELinux. I have done this before, but now i can't get it to work. The machine loads pxelinux.0, i see some messages. But it fails just after trying reading the first config file (the one with the mac address). It kinda says this (transcribed): CLIENT IP: 192.168.1.23 MASK: 255.255.255.0 DHCP IP: 192.168.1.93

Hi, I am trying to setup my own PXE boot server. I tried several PXE bootable Linux-Distributions. For example if I use the ubuntu netboot image from [1] it works quit well but there are a few other images they do not work in my case e.g.: RIPLinuX [2]. A friend tested this image on his PXE boot server with success. I also checked the download with md5sum. In my case I can see the boot menu [3].

Hello specialists In setting up a diskless X-Terminal I got stuck with the transfer of the ramdisk from the server to the target. With a ramdisk image size of about 60 Mb things go well, the file gets transfered completely and Linux boots perfectly. With a ramdisk image size of about 104 Mb the tftp transfer of the kernel succeds but the transfer of the ramdisk image fails. As tftp daemon I

Hi... I''m interested to find out how many people are running tftp-hpa versus atftpd. I''m almost a bit surprised in how many people seem to be using tftp-hpa; for modern Unix systems (including Linux), I would in general assume atftpd to be a better choice. If you have tried both and specifically chosen (as opposed to "it was already installed", etc.) I''d

Hello! I recently started testing curl's tftp options, and found that it crashed when trying to upload files using tftp because it didn't handle OACK properly. So, I'm attempting to fix it. Now, I have an endless loop: The client (my hacked curl) sends TFTP write request with options, server responds with OACK (tsize, blksize) client sends data packet, block 0 BUT: server responds

Uploading a >32MB file from a recent curl to tftpd fails because when the block number rolls back to 0, tftpd transmits the option ack again, instead of transmitting an acknowledgment for the block received. You don't see this problem when using the bundled tftp client because it doesn't set any of the options when uploading a file. Attached is a patch that fixes this, tested against

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

I'm having some difficulties pxe booting Solaris. So far I have tried the mboot.c32, and the pxegrub shipped with Solaris. At first I had some problems with blksize, but this disapeared when I changed from atftpd to tftpd-hpa. The point at which I'm stuck now is, the kernel and x86.microroot/x86.miniroot is loaded but then VMWare crashes. I might try with real hardware, but I thought

The current code only works iff the tsize option is set. This patch fixes the handling of the OACK packet and makes the code work with all combinations of the tsize and blksize options.
