The syntax of the configuration file requires that the address ends
with a semicolon and is put into curly braces.
DNS Server: TSIG Keys The main purpose of TSIGs (transaction signa-
tures) is to secure communications between DHCP and DNS servers.
They are described in Section 21.7.7 on page 467.
To generate a TSIG key, enter a distinctive name in the field labeled
‘Key ID’ and specify the file where the key should be stored (‘File
Name’). Confirm your choices with ‘Add’.
To use a previously created key, leave the ‘Key ID’ field blank and
select the file where it is stored under ‘File Name’. After that, confirm
with ‘Add’.
DNS Server: DNS Zones This part of the configuration uses several di-
alogs to configure the management of zone files (see Section 21.7.6 on
page 464). For a new zone, provide a name for it in ‘Zone Name’. To
add a reverse zone, the name must end in .in-addr.arpa. Finally,
select the ‘Zone Type’ (master or slave). See Figure 21.12. For each
zone, set additional options after selecting ‘Edit Zone ...’.
