dhcpd and ddyn-updates
I'm trying to follow the instructions at http://ops.ietf.org/dns/dynupd/secure-ddns-howto.html#reverse I'm testing with NetBSD 1.5.1 laptop with NetBSD 1.5 installed on a VMware in my hotel room. I'm running: marajade-[~] root 97 #dhcpd vmnet1 Internet Software Consortium DHCP Server V3.0rc10 and marajade-[~] root 98 #dhclient -V Internet Software Consortium DHCP Client V3.0rc10 {See below} (built from NetBSD /usr/src/ -current). The dhclient in 1.5 has been replaced with the compiled version. Mar 14 10:57:50 marajade named[11686]: journal file db.212.16.172.in-addr.arpa.jnl does not exist, creating it Mar 14 10:57:50 marajade dhcpd: delete IN PTR 253.212.16.172.in-addr.arpa. add 300 IN PTR 253.212.16.172.in-addr.arpa. leia.dasblinkenled.o: success. Mar 14 10:57:50 marajade named[11686]: zone 212.16.172.IN-ADDR.ARPA/IN: sending notifies (serial 200202202) Mar 14 10:57:50 marajade dhcpd: DHCPREQUEST for 172.16.212.253 from 00:50:56:eb:55:d3 via vmnet1 Mar 14 10:57:50 marajade dhcpd: DHCPACK on 172.16.212.253 to 00:50:56:eb:55:d3 via vmnet1 send fqdn.fqdn "leia.dasblinkenled.org."; send fqdn.encoded on; send fqdn.server-update off; It should be creating the reverse name "leia.dasblinkenled.org", but in fact it creates the name "leia.dasblinkenled.o.: Mar 14 12:33:25.371 update: info: client 172.16.212.1#64565: updating zone '212.16.172.IN-ADDR.ARPA/IN': deleting an rrset Mar 14 12:33:25.396 update: info: client 172.16.212.1#64565: updating zone '212.16.172.IN-ADDR.ARPA/IN': adding an RR marajade-[/etc/namedb] root 135 #host 172.16.212.254 Name: leia.dasblinkenled.o Address: 172.16.212.254 So, I tried to shorten things as leia.ox.org, but again, the last two got cut: Mar 14 12:55:07.501 update: info: client 172.16.212.1#64562: updating zone '212.16.172.IN-ADDR.ARPA/IN': deleting an rrset Mar 14 12:55:07.511 update: info: client 172.16.212.1#64562: updating zone '212.16.172.IN-ADDR.ARPA/IN': adding an RR marajade-[/etc/namedb] root 136 #host 172.16.212.254 Name: leia.ox.o Address: 172.16.212.254 After some futzing, I installed DHCP 3.0 (rather than rc10) and got the same thing. I am now running DHCP 3.0.1rc8, and I am successful. Ted: I didn't see anything in the release notes about this problem. THE DOCUMENT DOES SAY THAT I NEED RC7. It would be nice if the document would tell me WHY I need RC7 so that I can clue in to this. {other comments. My problems with forward are gone: marajade-[~] mcr 1137 %host marajade.dasblinkenled.org marajade.dasblinkenled.org has address 12.162.212.183 [yes, the #53 hotel ADSL has real IP in the rooms] I never did get dhclient to successfully update stuff. It complained about the TSIG values being wrong... I gave up and used nsupdate, which is a better solution for me anyway, since I can call it with the rest of the stuff that I call from dhclient-exit-hooks and PPP's ip-up. I will be upgrading my bind to a snapshot later today to try SIG(0) support. If someone wants to do TSIG now or SIG(0) later within dasblinkenled.org, just drop me a PGP/GPG message with a key. } ] ON HUMILITY: to err is human.
