Quick question I can't seem to find a google answer on.
I've got a machine that gets it's IP via DHCP. Now on our network, the DNS name is pulled off the machine and auto registered. However this machine won't push its domain name.
Do you mean Dynamic DNS updates?
Any ideas where a) the setting for this might be b) any manual step you can use to update the DNS name?
I looked at the nsupdate command, but I'm not sure that's the right command.
nsupdate will allow you to manually generate DDNS update packets, but generally you allow the DHCP client to do this. Are you using ISC dhclient? I'm not sure if dhcpcd supports DDNS, and pump most likely does not. Check /etc/dhclient.conf and its manual page for DDNS settings. Also, the DHCP server can control who does the update, either the DHCP server or the DHCP client, depending on how it is configured. And, of course, the DNS server may not allow just anyone to do updates, or may require signed updates using TSIG or SIG0. In secure environments, often only the DHCP server is authorized to update the DNS server.
Talking with the network guy, he recalls there being a graphical tool for Linux that would let you do this.
Never heard of this.
