checkpoint r80.20 gaia os dhcp server option 150

[Amir_Arama]

Hi,

i want to configure DHCP server on my GAIA os with dhcp server option 150 - tftp for ip phones.

i saw sk92473 but it says we can only use the options showed in https://linux.die.net/man/5/dhcpd.conf

and option 150 isn't there.

someone knows if this is supported and how to configure it? thanks

Strange -  https://linux.die.net/man/5/dhcpd.conf shows:

 option tftp-server-nametext;This option is used to identify a TFTP server and, if supported by the client, should have the same effect as the server-namedeclaration. BOOTP clients are unlikely to support this option. Some DHCP clients will support it, and others actually require it.

i couldn't find the text you put here inside the link 😕

Hi,

no, you could not find it there - you have to scroll down to the bottom of the page to find:

REFERENCE: OPTION STATEMENTS

DHCP option statements are documented in the dhcp-options(5) manual page.

Its the man page...

oh ok, anyway i think it's option 66 and not 150.

Hi Amir

you remember to write-protect the config file Else after reboot the changes are gone.

Hi Amir. Did you ever find the correct syntax for this? If so could you share. I need the same information. Thanks in advance.

Hello Tim

I think I have found correct syntax for the dhcpd.conf. I noticed that in this file is a lack of the "# Define Custom Options" and # "Global Config" separators. 

# Define Custom Options
option voip-tftp-server code 150 = ip-address;

# Global Config
subnet 192.168.0.0 netmask 255.255.255.0 {
[...]
option voip-tftp-server 10.101.0.10;
option voip-tftp-server 10.101.0.11;
}

Best regards
