INSTALLATION INSTRUCTIONS for ADNS 1. Read the security note below. 2. Standard GNU package build process: $ ./configure $ make # make install Unfortunately, since this is a beta, there is no good documentation yet. For now, use the comments in the public header file adns.h. You will find that adns requires a reasonably standard and up to date system. In particular, the build system assumes that you have ELF shared libraries. If you don't then please don't send me patches to support your kind of shared libraries, and don't send me patches to use libtool. I'm not interested in supporting non-ELF shared libraries. However, if you send me an appropriate patch I'd be willing to make it easy or automatic to disable the ELF shared library arrangements. The adnsresfilter utility uses `tsearch' from the C library (a la SVID and X/Open). If your C library doesn't have tsearch you will find that configure arranges for adnsresfilter not to be built. To rectify this, install a C library containing tsearch, such as the GNU C library. It is best if tsearch uses an automatically-balancing tree algorithm, like the glibc version does. Simple binary trees may perform badly. You will probably find that GNU Make is required. SECURITY AND PERFORMANCE - AN IMPORTANT NOTE adns is not a full-service resolver. It does no caching of responses at all, and has no defence against bad nameservers or fake packets which appear to come from your real nameservers. It relies on the full-service resolvers listed in resolv.conf to handle these tasks. For secure and reasonable operation you MUST run a full-service nameserver on the same system as your adns applications, or on the same local, fully trusted network. You MUST only list such nameservers in the adns configuration (eg resolv.conf). You MUST use a firewall or other means to block packets which appear to come from these nameservers, but which were actually sent by other, untrusted, entities. Furthermore, adns is not DNSSEC-aware in this version; it doesn't understand even how to ask a DNSSEC-aware nameserver to perform the DNSSEC cryptographic signature checking.
