[syslinux] pxelinux - use IP's for config files
I know it's possible to set a DHCP parameter to tell pxelinux to use a mac address as the pxelinux cfg file name-- is it possible to tell it to use the IP it is being assigned as the filename? Thanks, James S. Martin, RHCE Contractor Administrative Office of the United Sates Courts Washington, DC (202) 502-2394
Yep, this is from my ISC DHCPv3 dhcpd.conf:
Note, this causes pxelinux to search first for the full mac address;
if that fails it does the normal ip-based logic and fallback to default.
Note the mac address should not be zero-padded (just put :e: not :0e:).
# PXELinux config file becomes "pxelinux.cfg/{MACADDRESS}"
# eg. "pxelinux.cfg/1:58:fa:84:cf:55:e"
# This way we can have dynamic addresses yet still physical-machine-specific
# configs
option pxelinux.configfile concat("pxelinux.cfg/",
binary-to-ascii(16, 8, ":", hardware));
