If you prefer to edit the DNS configuration files manually, follow these steps.
Note: Files with a u extension are for the unbound nameserver, and files with an
i extension are for the Internet nameserver.
Important: You should only edit zone files for a master name server. Never edit the
slave name server files. The file names shown below are for a master name server.
1 Log into the Sidewinder G2 and enter the following command to switch to
the admin role:
srole
The following two steps assume you have database files named
domain.db and reverse.db in your system. Substitute your file names
as required.
2 Open the /etc/namedb.u/domain.db and /etc/namedb.i/domain.db files in a
UNIX text editor and make the necessary changes.
3 Open the /etc/namedb.u/reverse.db and /etc/namedb.i/reverse.db files in a
UNIX text editor and make the necessary changes.
4 Open the /etc/named.conf.u and /etc/named.conf.i files in a UNIX text editor
and make the necessary changes.
Note: If you use the /etc/named.conf.* files to change an existing master zone
into a slave zone, you must also manually remove the old zone files in your
/etc/namedb.* directories.
5 If you have added new files, you must change the files to the correct Type
Enforcement types.
To do this, type the following command and insert the names of the file(s)
you edited in steps 2, 3 and 4. For non-Internet (unbound) burbs, in place of
x type the identifier u. For the Internet burb, in place of x type the index
number of the Internet burb. (Use the region show command to determine
the index number.)
chtype DNSx:conf filename
6 Increment the serial number after every change to the master files.
7 Enter the following command to restart DNS.
ndc restart
Note: Any files created by named daemons, such as zone backup files or query
log files, have types of DNSu:file or DNSx:file.
8 Check /var/log/daemon.log for any errors.
