what are the steps to set/add option 85 in suse11 to the dhcp server.

Hi dmiller,

which SP are you on? From SLES11SP1 “man dhcp-options”:

[QUOTE] option nds-servers ip-address [, ip-address… ];

      The nds-servers option specifies a list of IP addresses of NDS servers.[/QUOTE]

It’s likely that your dhcpd will already understand the option name “nds-servers”, which is option 85 (per RFC 2241).

Jens

What do you mean by “suse11”? Posting in this forum suggests SUSE Linux
Enterprise Server (SLES) 11 but it could also mean SUSE Linux Enterprise
Desktop (SLED) 11, openSUSE 11.x, or even Novell Open Enterprise Server
(OES) 11.

Whilst all are likely to be using ISC DHCP how they’re configured
depends on which “suse11” you’re using, particularly if it’s OES11.

Please can you post the output from “cat /etc/*release”.

HTH.

If that was no typo when composing the forum message: It is “nds-server”, not “dns-server”… “Novell Directory Services”.

sorry, what I posted was a typo.

This is the config file that I run.
######################################################
option domain-name “asdf”;
option domain-name-servers x.x.71.206, x.x.2.1;
option routers x.x.68.250;

option lpr-servers x.x.71.253;
option nds-server x.x.71.253;
ddns-update-style none;
default-lease-time 14400;
subnet x.x.68.0 netmask 255.255.252.0 {
range x.x.69.1 x.x.70.253;
default-lease-time 14400;
max-lease-time 172800;
}
#######################################################

this is the error I get.

########################################################

Another typo, it’s “nds-servers” (plural) as you wrote in your first
reply …

Hi,

option nds-server x.x.71.253;

Typo on my end, too - see “man dhcp-options”:

[QUOTE]option nds-servers ip-address [, ip-address… ];

      The nds-servers option specifies a list of IP addresses of NDS servers.

Try “option nds-servers x.x.71.253”.
