dhclient and ddns?

Hi.

I'm running a DNS server and a DHCP server on a linux mandrake 9.1 box. I have configured the dynamic DNS and windows and MAC clients register their hostnames with the DDNS, but how can I configure a linux client that is using dhclient to register with DDNS?

THanks,

Luis

I'll assume you are using the latest version of dhcp and dns, since thats what i use. In /etc make a file called dhclient-<interface>.conf, where <interface> is the interface you want to dhcp on, (eth0, eth1, wlan0, etc)

In mine, it appears as this:

Code:

send fqdn.fqdn "butterfly";
send fqdn.encoded on;
send fqdn.server-update on;

key "DHCP_UPDATER" {
        algorithm hmac-md5;
        secret "yidYTwQ7zxt6lON2fmMfuA==";
}

zone mydomainname. {
        key DHCP_UPDATER;
}

I don't know if you have a key supplied in your dhcp.conf and named.conf or not, if not, then ignore the last two statements, and only keep the first 3 "send" things.

Then update with "dhclient -cf /etc/dhclient-<interface>.conf"

Thanks for the answer. I will give it a try.

I'm really interested in the functionality of ddns on redhat 9.0. If anyone could point me in the right direction to do some research I'd appreciate it.

Luis,

Could you guide me on how to setup DDNS server on RedHat 9.

Thanks,

Ben,

I've believe the following works as well:

send host-name "hostname"

key "DHCP_UPDATER" {
algorithm hmac-md5;
secret "yidYTwQ7zxt6lON2fmMfuA==";
}

zone mydomainname. {
key DHCP_UPDATER;
}
