I'm using CentOS so I'll try with the latest 2.1.x from git
The problem which bothers me is that I need more than classic ip-mac pairing. Beside the IP address I need to return a few other parameters to cable modems/MTA.
For example ISC DHCP config for regular modems is:
host blaBlaBla { filename "confingFile.cm"; fixed-address 192.168.12.167; hardware ethernet 00:cc:ab:11:cc:22; }
As you can see, I'm returning the IP address and the name for config file.
Is this possible with FreeRadius DHCP ?
Should be. The IP address assignment (whether static or dynamic) is easy enough with a special instance of sqlipool like in the example. If you only want static IP then you can even use only files without db.
As for the filename, dictionary.dhcp has DHCP-Boot-Filename attribute,
Just tested pxe boot (with the help of virtualbox and linux containers), and it works as expected. Some notes though: (1) the option "filename" in ISC's dhcp should refer to pxe boot image, something like host clientname { filename "/tftpboot/tftpboot.img"; ... } If your system is x86, and the OS/kernel loaded is linux or can be booted with multiboot (e.g. solaris), then usually you can just use pxelinux in "filename" option. pxelinux can then load the correct config file for each host using a host-specific configuration file (based on the hosts' MAC or IP address), or it can load the default config file: http://www.syslinux.org/wiki/index.php/PXELINUX Are you sure you're actually using per-host filename option instead of a common one? (2) I tested by adding this block in FR's DHCP-Discover and DHCP-Request section: update reply { DHCP-Boot-File-Name = "/boot/pxelinux.0" } it works as expected. The attribute is sent to all hosts requesting DHCP address, but only hosts doing network boot will acttually use it. A cleaner approach would probably be checking if the client sends DHCP-Parameter-Request-List = DHCP-Boot-File-Name ... and only send the reply then. -- Fajar
