bind中rndc配置好之后，开启named的时候提示unkown option default-key/server/port 解决办法

I had the same problem on a Debian server this week. As you probably noticed when Googling, there are a lot of different things that could cause this problem.

The first thing to check is whether or not named is listening on the port that rndc uses to talk to it: tcp 953

netstat -paln | grep 953

should return a line showing named is listening.

The problem on my DNS server was just that: Nothing was listening on port 953. In /var/log/daemon, I was seeing:

named[7030]: couldn't add command channel 127.0.0.1#953: file not found

What worked for me was to copy the key "rndc-key" {...} clause from rndc.conf and paste it into a file called /etc/bind/rndc.key, rather than placing it directly in named.conf.

rndc.key is read by named, and rndc.conf is read by rndc.
