Hi all, I'm trying to configure DHCP to make it update DNS records whenever a new IP address is assigned... but no way to get it working! 1. As root, I've created the key to be used between named and dhcpd for dynamic DNS updates: dnssec-keygen -a HMAC-MD5 -b 512 -n HOST dhcp-updater 2. Then, I've modified /etc/dhcpd.conf as following: ... allow client-updates; ddns-updates on; ddns-domainname "agamura.com."; ddns-rev-domainname "in-addr.arpa."; ddns-update-style interim; key dhcp_updater { algorithm hmac-md5; secret "GC2kwEdJxhMol2e...; }; zone agamura.com. { primary 192.168.1.1; key dhcp_updater; } zone 1.168.192.in-addr.arpa. { primary 192.168.1.1; key dhcp_updater; } ... 3. and /etc/named.conf as following: ... acl "home" { 192.168.1.0/24; 127.0.0.1; }; options { directory "/var/named"; pid-file "/var/run/named/named.pid"; dump-file "/var/named/data/cache_dump.db"; statistics-file "/var/named/data/named_stats.txt"; allow-query { "home"; }; forwarders { 195.186.1.111; 195.186.4.111; }; }; ... key dhcp_updater { algorithm hmac-md5; secret "GC2kwEdJxhMol2e...; }; zone "1.168.192.in-addr.arpa" { type master; file "1.168.192.in-addr.arpa.zone"; notify yes; allow-update { key dhcp_updater; }; }; zone "agamura.com" { type master; file "agamura.com.zone"; notify yes; allow-update { key dhcp_updater; }; }; 4. Finally, I've restarted named and dhcpd. That is it! Am I missing something important to get this stuff working (I'm running FC3)? Thanks for your help, j3d. -- ---------------------------------------- Giuseppe Greco ::agamura:: phone: +41 (0)91 604 67 65 mobile: +41 (0)79 602 99 27 email: giuseppe.greco@xxxxxxxxxxx web: www.agamura.com ----------------------------------------
