this may be a strange question but... i want to do some testing of tftp with and without tsize option. is there a way to start in.tftpd without enabling the tsize option? or will i have to install new tftp server that does not support tsize option? perhaps this? /usr/sbin/in.tftpd -r tsize

Perhaps a stupid question, but I've read through the changelog and the e-mail archive and can find no answer. I'm wondering why "tsize" is a necessity. Seems like the TFTP protocol correctly handles EOF. Does the code need to know in advance how large the file is going to be? If it just happens to have been written this way, would you be open to a change which eliminates the requirement? Thanks, Scott

...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 options set (from TFTPd server). tsize 0 and blksize 1408. What seems to confuse it is that it gets back both acknowledgements in the same TFTP option acknowledgement packet. That is, the TFTP server's option acknowledgement packet has tsize option acknowledgement (tsize = 145744) and also blksize option acknowledgement (blksize =...

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 constraints)? My understanding is that tftp packet numbers are from 0-65535 yielding a maximum size of 32MB. Yet, from the revision history, it seems pxelinux can...

...server, this works fine and the client begins to load NTLDR. However NTLDR calls a file called ntdetect.com from the server. The server ACK's the call and then ends up failing. Here's the error thought packet captures: Read Request, File: ntdetect.com, Transfer type: octet, blksize=1432, tsize=0 Option Acknowledgement, tsize=47564 Eoor Code, Code: Option negotiation failed, Message: Bad TFTP options After this the whole process fails and halts. Basicaly is there something I'm missing. Am I using the wrong version or is there a configuration change I can do.

...and also the used port (y) for the transfer in line 273 Than you perform a core_udp_disconnect at line 286 Now you perform a new core_udp_connect to port y which set the source port to x + 1 at line 287 for example: Client | Server TFTP get file 2900 > 69 Response tsize 2900 < 7012 ACK blk 0 2901 > 7012 <-- wrong source port Now the TFTP is failing, because he expect the filetransfer client port as the same as the initial filerequest. Maybe that help to solve the problem Regards Michael

...sers of the 6.03-pre6 version of syslinux but testing with this version reveals the same issue for me. The problem I am experiencing is that when I attempt to PXE boot my Hyper-V VM client, I can see it requesting the syslinux.efi file from the tftp server. The initial request has options for both tsize and blksize included, and the response packets from the tftp server include both options as well. It appears as though the file doesn't actually get transferred until a later packet request (this time with only one option of blksize included) gets sent from my VM client to my tftp server.

But in change log for the 3.70 version (online at http://www.kernel.org/pub/linux/boot/syslinux/syslinux-3.70.lsm) you can read "PXELINUX: We no longer require a TFTP server which supports the tsize option for all transfers." Does that mean that we can delete this requ...

Hi I'm working on an update of the openbsd tftpd, mainly to support RFC 2349 (tsize option; and 2347-2348 too). In fact, i backport from tftp-hpa (which came from an old openbsd cvs). I know, i can use tftp-hpa but first it doesn't compile on openbsd, second, i hope the backport could be include in openbsd cvs ... does someone know a tftp client or a test to really know what...

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 blksize option. Then it gets back an OACK with only one option (the blksize of 14...
