Figure 21.4 DNS Server: Logging
Using ACLs
Use this window to define ACLs (access control lists) to enforce access restrictions.
After providing a distinct name under Name, specify an IP address (with or without
netmask) under Value in the following fashion:
{ 192.168.1/24; }
The syntax of the configuration file requires that the address ends with a semicolon and
is put into curly braces.
TSIG Keys
The main purpose of TSIGs (transaction signatures) is to secure communications between
DHCP and DNS servers. They are described in Section 21.8, "Secure Transactions"
(page 300).
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 (Filename). Confirm your choices with Add.
