To add some filter rules in conf file

[Reissom Beshir]

As people mentioned in prior discussions, the server nomally provides options that the client has requested in the Parameter Request List (option 53).

Are you trying to configure a PXE client?  I think the man page may have a section on that.

It would help to know what you want to accomlish here and what client you are configuring.

Hi,

I even tried:
class "rule1" {
match if substring (option dhcp-client-identifier, 0, 5) = 01:00:19:7d:72;
}

subnet 192.168.1.0 netmask 255.255.255.0 {

pool {
option time-offset -12345;
option boot-size 65000;
range 192.168.1.66;
allow members of "rule1";
}

default-lease-time 86500;
max-lease-time 86500;
option routers 192.168.1.254;
option domain-name-servers 192.168.1.254;
}
=> same result. option time-offset and boot-size are not sent as part of dhcp offer message.

thanks
Ashmath

  option routers 192.168.1.254;
  option domain-name-servers 192.168.1.254;
  }


  => it didn't work completely. I did get dhcp offer message but the options: time-offset and boot-size were not sent as part of dhcp offer. Any reasons ? How do I make it work ?

  thanks

      For example, If I find string "Amino" in the option dhcp-client-identifier, then the range would be  A, options B and if the string is "Phone*" then the range would be C and options D.



    Look at the section on classes in "man dhcpd.conf"
