[ipxe-devel] iPXE: Authentification Problem

[Sara Martínez]

This is my dhcpd.conf:


option space ipxe;
  option ipxe-encap-opts code 175 = encapsulate ipxe;
  option ipxe.priority code 1 = signed integer 8;
  option ipxe.keep-san code 8 = unsigned integer 8;
  option ipxe.skip-san-boot code 9 = unsigned integer 8;
  option ipxe.syslogs code 85 = string;
  option ipxe.cert code 91 = string;
  option ipxe.privkey code 92 = string;
  option ipxe.crosscert code 93 = string;
  option ipxe.no-pxedhcp code 176 = unsigned integer 8;
  option ipxe.bus-id code 177 = string;
  option ipxe.bios-drive code 189 = unsigned integer 8;
  option ipxe.username code 190 = string;
  option ipxe.password code 191 = string;
  option ipxe.reverse-username code 192 = string;
  option ipxe.reverse-password code 193 = string;
  option ipxe.version code 235 = string;
  option iscsi-initiator-iqn code 203 = string;

 option ipxe.priority 1;

…

…

 if (exists ipxe.username and exists ipxe.password) {
          filename "/ltsp/i386/menu.ipxe";
    } else if (exists user-class and option user-class = "iPXE") {
          filename "/ltsp/i386/menu-login.ipxe";
   } else {
    filename "/ltsp/i386/undionly.kpxe";
 }



And my menu-login.ipxe :


#!ipxe

 login

ifopen net0
set net0/175.190:string ${username}
set net0/175.191:string ${password}

dhcp net0
chain ${net0.dhcp/filename}




 I checked these packets with wireshark: DHCP discover and DHCP request.
They contain the Etherboot encapsulation (175) with the options:

         ipxe.bus-id (177), ipxe.bzimage (24), ipxe.elf (34),
ipxe.multiboot (25), ipxe.pxe (33), ipxe.pxeext (16), ipxe.version (235) ,
ipxe.http (19), ipxe.iscsi (17), ipxe.dns (23), ipxe.tftp (21), ipxe.menu
(39), ipxe.aoe (18).

And the options ipxe.username and ipxe.password are not in the packet.
