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

Hi ALL Has anyone any insight as to why RedHat Enterprise Level 5 is broken as far as PXE booting is concerned. Is there a Protocol communication problem ???????? Are there alternative tftp-severs that work for the RHEL5.. It seems: the PXE CLIENT when booting cannot access files in the "pxelinux.cfg" dir RHEL4 works just fine !! ( kernel 2.6.9-22.EL) with

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

Hi, Using syslinux 3.80, I'm seeing pxelinux.bin hanging after the (succesfull) transfer of the default file. Running a lan trace, it appears that all goes fine until the time pxelinux sends a TFTP RRQ for menu.c32 to the TFTP server, gets the first data packet back, and apparently freezes at this point. The TFTP server then times out and retries (3 times) then finally sends an error packet

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

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:

I am having a problem while trying to download anything from a recently configured tftp boot server. Here are the configuration for the dhcpd.conf option domain-name="domain.com"; default-lease-time 900; max-lease-time 1800; ddns-update-style none; authoritative; allow bootp; allow booting; option space PXE; option PXE.mtftp-ip code 1 = ip-address; option PXE.mtftp-cport code 2

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"

Hi, I have a tftp client which loads quite happily from a tftpd built from netkit-tftp-0.16 but which fails to load from from a tftpd built from tftp-hpa 0.29. In both cases, tftpd was built from pristine sources and run from xinetd under Redhat 7.3. [netkit-tftp-0.16 is the ancestor of tftp-hpa, predating HPA's maintenance of same] [the tftp client also.. .. fails with the prebuilt tftpd

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

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

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 is good or

Hi, i try booting a PXE equipped client with pxelinux. The problem is: after receiving the file pxelinux.0 it requests pxelinux.cfg/C0A86451 and aborts. tcpdump: .... 16:01:58.786946 192.168.100.81.2073 > saturn.1337: udp 4 16:01:58.787033 saturn.1337 > 192.168.100.81.2073: udp 516 (DF) 16:01:58.787202 192.168.100.81.2073 > saturn.1337: udp 4 16:01:58.787528 saturn.1337 >
