Hi, I am a happy user of version 4.06 and have been hoping to upgrade the 5.x series (for the HTTP bits). I have the following problems with the 5.11-pre7 build: 1. TFTP load is horribly slow ... even when the two REAL machines are connected to the same switch. For a typical RHEL installation, the vmlinuz loads ... the initrd.img loads very very slowly and just times out (I waited over 10 mins) A minor issue: The TFTP doesn't clear screen before the "kernel" start loading so the text appears on top of the splash (at the bottom if the screen) ... :( The above two are NOT seen on the 4.06 branch. 2. HTTP loading just doesn't work! :( :( I have tried these with the 4.10, 5.10, 5.11 branches, no luck! As of today I have noticed an error message:. --- msg --- Loading http://A.B.C.D/os/rhel/6.4/x86_64/disc1/images/pxeboot/vmlinuz... netconn_write error -5 failed: no such file or directory --- msg --- Ofcouse I can wget/firefox this file fine! :) :) The corresponding entry in my 'default' file is: --- snip --- label rhel-6.4-x86_64-http menu label RHEL 6.4 (x86_64) HTTP (Experimental; DO NOT USE) kernel http://A.B.C.D/os/rhel/6.4/x86_64/disc1/images/pxeboot/vmlinuz initrd http://A.B.C.D/os/rhel/6.4/x86_64/disc1/images/pxeboot/initrd.img append lang=en_US keymap=us ip=dhcp noipv6 method=http://A.B.C.D/os/rhel/6.4/x86_64/disc1 vga=785 --- snip --- If the following helps: Server (OptiPlex 755) lspci: # lspci | grep -i network 00:19.0 Ethernet controller: Intel Corporation 82566DM-2 Gigabit Network Connection (rev 02) Client (OptiPlex 960) lspci: # lspci | grep -i network 00:19.0 Ethernet controller: Intel Corporation 82567LM-3 Gigabit Network Connection (rev 02) Regards, Shantanu

Ummm ... apologies up front ... but what would be the exact command to run? Although I've had this eemail exchange once before, I don't recollect the commands.

Not "netconn_write failed: -5" ? Q: Exact message for v 5.11-pre7 --- snip --- netconn_write error -5 failed: No such file or directory --- snip --- I am also answering a few other questions asked by Gene Cumm: Q: I presume lpxelinux.0 and not pxelinux.0? Have you tried pxelinux.0 for TFTP just in case? Ans: Yes, I have tried "lpxelinux.0" renamed to "pxelinux.0" and just the pxelinux.0> I have tried these with the 4.10, 5.10, 5.11 branches, no luck!Q: Any particular versions? Ans: Many intermediates ... can't really upset my cluster too frequently! :( Tested versions: 4.06 5.01 5.02-pre3 5.10 5.10-pre1 5.10-pre2 5.11-pre2 5.11-pre7 6.01 Q: BIOS rev on the 960? Ans: A17 FWIW, BIOS rev on the 755 is 'A22' Q: How are you using a splash? DISPLAY directive, vesamenu.c32 MENU BACKGROUND? Ans: vesamenu.c32 MENU BACKGROUND? With so many versions around, its kinda getting confusing (for me, at least) :) :) Thanks for your patience, Regards, Shantanu

Your scenario failed on my OptiPlex 760 but with 6.02, it works. See also http://bugzilla.syslinux.org/show_bug.cgi?id=19 -- -Gene

Your scenario failed on my OptiPlex 760 but with 6.02, it works. See also http://bugzilla.syslinux.org/show_bug.cgi?id=19 Nope, still no joy on the physical machines. Different symptoms though. On the physical machines: The HTTP starts loading the file and after about a few seconds comes back to the menu. I do NOT see the HTTP GET in my Apache log. The TFTP stalls (~5min wall time). I do not see a "sending /tftpboot/pxelinux.0" in my dnsmasq's TFTP. In my ProxMox Virtual Machines: (ProxMox 3.1 with all the free latest updates) HTTP: works TFTP: works Note: I am using lpxelinux.0 renamed to "pxelinux.0" /This should really be highlighted somewhere!/ :) :) Regards, Shantanu
