This is not truth, I have access to both IPv4 and IPv6 Internet. As wrote all other applications are working with with IPv6. Just ipxe has problem. But that output was from real machine connected to IPv6 network. ====== Below is output from ipxe started in qemu, in the reproducible way as described in the first post. So you can verify that problem is also when running in qemu, not only on real machine. $ git clone git://git.ipxe.org/ipxe.git $ cd ipxe/src $ sed 's/#undef\tNET_PROTO_IPV6/#define\tNET_PROTO_IPV6/' -i config/general.h $ make -j8 bin/rtl8139.rom $ qemu-system-x86_64 -netdev user,id=n1 -device rtl8139,netdev=n1,romfile=bin/rtl8139.rom -boot order=n -curses SeaBIOS (version 1.10.2-1) iPXE (http://ipxe.org) 00:03.0 CA00 PCI2.10 PnP PMM+07F91DD0+07ED1DD0 CA00 iPXE (PCI 00:03.0) starting execution...ok iPXE initialising devices...ok iPXE 1.0.0+ (ebf2) -- Open Source Network Boot Firmware -- http://ipxe.org Features: DNS HTTP iSCSI TFTP AoE ELF MBOOT PXE bzImage Menu PXEXT iPXE> dhcp Configuring (net0 52:54:00:12:34:56)...... ok iPXE> route net0: 10.0.2.15/255.255.255.0 gw 10.0.2.2 net0: fec0::5054:ff:fe12:3456/64 gw fe80::2 net0: fe80::5054:ff:fe12:3456/64 iPXE> show net0/ip net0.dhcp/ip:ipv4 = 10.0.2.15 iPXE> show net0/ip6 net0.ndp.0/ip6:ipv6 = fec0::5054:ff:fe12:3456 iPXE> Those addresses are used by qemu itself (I guess it is doing some IPv6 NAT, like for IPv4) and ipxe has somehow problems... As it even cannot access IPv4 world. ====== So can somebody else reproduce that this is a real problem on *working* IPv6 network when running ipxe in qemu? I think it should be easy, as it is needed to execute just 5 commands. -- Pali Rohár [email protected]
