...pconfig sends a DHCP_DISCOVER, server A answers with a DHCP_OFFER, server B answers with a DHCP_OFFER, ipconfig sends a DHCP_REQUEST for server A, ipconfig accepts the DHCP_OFFER from server B instead of DHCP_ACK from server A. <== BUG The reason for this was that in dhcp_parse(), DHCPOFFER and DHCPACK returned the same value (=1). So I had to modify the return values, and I thought it would be better to return the constants DHCPOFFER, DHCPACK etc instead of 1,2,3... I tried to keep the changes as minimal as possible. I'm not experienced with the diff program, so please excuse the way I'...

I have 2 script. Script "A", Script "B".

...nt. The return code is EFI_UNSUPPORTED but the error is ignored after the return from the UDP send command in BIOS. Should this be handled differently? Resolution for problem 2: This is my implementation. Hopefully it is a good start to help us get to the correct approach. In pxe.c, I populate DhcpAck packet with all of the correct ip addresses and netmask. In udp.c, at the end, I disable UseDefaultAddress and populate missing correct ip addresses. Details and code below. My approach: In efi/pxe.c: #include <syslinux/firmware.h> #include <syslinux/pxe_api.h> #include "efi....

This patch adds to Com32 modules the capabilities of accessing the EFI environment The idea is simple, the EFI parameters "image" and "table" received by syslinux.efi's efi_main() are stored in the "firmware" structure, next they are retrieved from the Com32 module which is linked against the gnu-efi static library. The Com32 module can use the EFI

These files are efi/pxe.c and efi/udp.c. In efi/pxe.c: In net_parse_dhcp function. If ProxyOffer has been received, start with DhcpAck packet since it is the most complete.

Thanks Rowland and Louis! :) Ok I'm going to test the failover mode! ;) Do I need to set the same value for NSRVS in dhcp-dyndns.sh? ( the first AD server, "S4" for me ) Or can I keep NSRVS=S4.ariane.intra on server S4 and NSRVS=S4bis.ariane.intra on server S4bis? It seems to be more secure for me if the first server switch off...
