[ipxe-devel] iPXE concurrent use of two interfaces in different subnets not working

[Laborde, Louis (HP Servers)]

Hello Michael,

Can this "sanhook" command be encoded in an iPXE-specific DHCP option, like keep-san is,
of does this script need to be pointed to by a boot filename URL, to avoid any manual action?

Thanks,
Louis

You'll need to use a slightly more manual process to avoid the automatic closing of interfaces which iPXE does to conserve memory:

#!ipxe
dhcp net0
sanhook ${root-path}
dhcp net1
chain ${filename}
