The following packages need to be downloaded for installation.2
| Package | URL | Version |
| IP-Filter | ftp://coombs.anu.edu.au/pub/net/firewall/ip-filter | 3.2.10 |
| DP | ftp://ftp.acn.purdue.edu/dp | 4.0 |
| BIND | ftp://ftp.isc.org/isc/bind/src/8.2/ | 8.2 |
It is a good idea to download the documentation package for BIND, as well as the source code. When extracting the files from the BIND archive, be aware that they do not place themselves into a convenient, named directory, but just spew out in place.
