EXTERNAL: dhcp-workers Digest, Vol 22, Issue 2

Thanks for the replies and have a couple of questions:

I took Jon's vendor-options and placed them in my "/etc/dhcpd.conf" file and it started up just fine. A few members mentioned that I needed to update the "/etc/dhclient.conf" which I'm not using (just taking the defaults). But if new options are added to the /etc/dhcpd.conf file, I should be able to run "dhclient -R platform.name" to determine the set value of the option? If works just fine on all the standard options that I sent on the server side?

I'm not sure if I'm setting up the server side incorrectly (is there a way to even test platform.name on the server side?) or I need to create a specific "/etc/dhclient.conf" for adding these new options.

Does anyone have this working with new options that could forward an example of the dhcpd.conf and dhclient.conf.

Thanks,
John

I wish to setup a few new options in my /etc/dhcpd.conf file. Currently, running with V3.0.5_RedHat. During my testing I've added a new option "platform-name" and restarted the DHCPD daemon. It starts fine but when I run "dhclient -R platform-name" I get the response that the option does not exist?

Any help would be appreciated and here is a copy of my "/etc/dhcpd.conf" that I'm testing with:


ddns-update-style interim;

# Declare Setup Information
option platform-name code 130 = text;

subnet 158.187.231.0 netmask 255.255.255.0 {
option subnet-mask           255.255.255.0;
option domain-name-servers   158.187.231.217;

host test {
        hardware ethernet 00:1A:A0:AF:48:F6;
        fixed-address 158.187.231.214;
        option host-name test;
        option platform-name "isis";
        }
}

I've tried both "text" and "string" and get the same response that the option does not exist. Any standard options "root-path" or "host-name" work just fine.

Thanks,
John Johnson

   dhcpd.conf is read by the server. The dhclient tool uses a diferent  
config file. You should learn him the definition of "platform-name" in  
/etc/dhclient.conf

Wouldn't you use vendor specific options to do something like that?  
Seems that it would be more RFC compliant.  I say "seems" because I'm 
not sure.  Please anyone correct if I'm wrong.

option space vendor-options;
option vendor-options.platform-name     code 1  = text;
option vendor-options.someotheroption   code 2  = text;
option vendor-options-43 code 43 = encapsulate vendor-options;

But I do agree with Rene, you would also need to make some declaration 
in the client side config file.

Jon
