Understand how the CGI scripts function.
There are two scripts that work together to return an NSLOOKUP list query (ls) for a specified zone in
a CGI link.
dnszone.pl—Runs the CGI process. In the subnet column in Figure 24, the entry 172.21.10.0/24 is
an active link that calls the dnszone.pl script.
The active link is coded as:
<td><a href="/cgi-lwt/dnszone.pl?zone=10.21.172.in-addr.arpa.">172.21.10.0/24</a></td>
Once invoked, dnszone.pl calls the second script, dnszone_dump.
dnszone_dump—An expect script that steps through the NSLOOKUP interactive mode and returns
the output of a "ls [ZONE]" command to the dnszone.pl script. The zone list, returned to the
requesting web-based management browser, appears:
ls 10.21.172.in-addr.arpa.
