Running the named Nameserver Daemon

Running the named Nameserver Daemon

Finally! You can now start named with /etc/rc.d/init.d/named start. You should see messages similar to the ones that follow in the syslog (or another location, according to the logging configuration you have set up). One way to do this is to monitor the log file with the tail command; that scrolls the changes in the file down the screen:

# tail -f /var/log/messages

You can use rndc to interact with this instance of named. Running rndc without arguments displays a list of available commands, including ones to reload or refresh zones, dump statistics and the database to disk, toggle query logging, and stop the server. Unfortunately, rndc does not yet implement all the commands that were supported by ndc — the control program shipped with earlier versions of BIND.

You should now be able to resolve 1.0.0.127.in-addr.arpa locally (try dig @localhost 1.0.0.127.in-addr.arpa PTR +norec) and other names via recursive resolution. If you cannot accomplish this resolution, something is wrong, and you should read the "Troubleshooting DNS" section later in this chapter to diagnose and correct your problem before proceeding further. Remember to read the logs!
