---|
20 | =head1 DESCRIPTION |
---|
21 | |
---|
22 | This contains functions to generate network config file from C<Netzone> and |
---|
23 | C<Nethost> object. |
---|
24 | |
---|
25 | These config file can be: |
---|
26 | |
---|
27 | =over 4 |
---|
28 | |
---|
29 | =item DNS zone files |
---|
30 | |
---|
31 | A standard DNS zone generated from a header and entries found in bases |
---|
32 | |
---|
33 | =item DNS reverse zone files |
---|
34 | |
---|
35 | A reverse DNS zone genarated from a header and entries found in bases |
---|
36 | |
---|
37 | =item A DHCP host list |
---|
38 | |
---|
39 | A file well formated host list to be included in dhcpd config file. |
