Hi there, I am having some difficulties getting dynamic DNS running on a new FC4 server I just built. Some web searching has not really given me the results to figure out what is broken. I was hoping somebody on this list could assist me with troubleshooting it. I have replaced the hostnames and IP address to protect the innocent. I am trying to get the A record for machine.hostname.com to be regularly updated to my primary name server at 111.111.111.111 . But this appears to not be happening. ---- snip ---- send host-name "machine.hostname.com."; send fqdn.fqdn "machine.hostname.com."; send fqdn.encoded on; send fqdn.server-update off; key machine.hostname.com { algorithm HMAC-MD5; secret "a;dflkja;sldkfja;lkdjq;wlekjr;qlkwejr;lqkwjer;lkqjewr"; } zone hostname.com { primary 111.111.111.111; key "machine.hostname.com"; } interface "eth0" { send host-name "machine.hostname.com."; send dhcp-client-identifier 00:C0:F0:1F:21:E2; send dhcp-lease-time 3600; supersede domain-name "host.hostname.com hostname.com"; prepend domain-name-servers 127.0.0.1; request subnet-mask, broadcast-address, time-offset, routers, domain-name, domain-name-servers, host-name; require subnet-mask, domain-name-servers; script "/sbin/dhclient-script"; } --- snip ---
