   1 INSTALLATION INSTRUCTIONS for GNU ADNS
   2
   3 1. Read the security note below.
   4
   5 2. Standard GNU package build process:
   6    $ ./configure [--disable-dynamic] [--prefix=... ...]
   7    $ make
   8    # make install
   9
  10 Unfortunately, there is no comprehensive documentation yet.  For now,
  11 use the comments in the public header file adns.h, and for the C
  12 programs their usage messages.  If you find this information
  13 ambiguous, incomplete or wrong, please report it as a bug.

  16 TESTED PLATFORMS
  17
  18 The following platforms have been tested at at least some point and
  19 should work - please report if they don't:
  20  adns version  OS
  21    1.0          Linux glibc 2.1 (actually tested on Debian 2.2)
  22    1.0          Solaris 2.6, 2.7, 2.8 [3]
  23    1.0          FreeBSD 3.2, 4.0 (no poll(2), so no adnsresfilter)
  24 The following work, but only with --disable-dynamic:
  25    1.0          IRIX 6.5 *not* with GCC [1], [2]
  26    1.0          AIX 4.1.5
  27    1.0          HP-UX 10.20, 11.00
  28 Later versions of the same OS should work too.  Usually entries in
  29 this table mean adns passes its own regression test, when compiled
  30 with GCC, and appears to install and run correctly.  If you have more
  31 information for this table please let me know.
  32
  33 Notes/known problems:
  34    [1] IRIX 6.5 inet_ntoa seems to break with GCC.
  35    [2] The SGI IRIX compiler produces many spurious warnings.
  36    [3] Dynamically linked, needs some help to find libadns.so.1.0.
  37
  38 The following platforms are known to be deficient and will not work:
  39    Solaris 2.5                  Lacks vsnprintf - install glibc ?
  40    TruUnix64 (DEC UNIX 4.0f)    Lacks vsnprintf - install glibc ?
  41 Please don't report these problems unless you have a nice,
  42 straightforward solution or workaround for them.  (I don't consider
  43 including a `vsnprintf' implementation nice, so don't send me one.)
  44
  45
  46 PORTABILITY INFORMATION
  47
  48 You will find that adns requires a reasonably standard and up to date
  49 system.  Systems which are neither GNU nor UNIX are not supported.
  50
  51 The build system assumes by default that you have ELF shared
  52 libraries, and that the directory in which libadns.so.1 will be
  53 installed is on your dynamic library search path.  If your system
  54 doesn't have ELF shared libraries then dynamic linking is not
  55 supported by adns.  Use the --disable-shared configure option.
  56 Please don't send me patches to use libtool (which I dislike).
  57
  58 Compilers other than GNU C should work, but are not well-tested.  Feel
  59 free to send me patches to improve the situation.  However, the
  60 Makefiles only know how to use GCC to make dynamic libraries.
  61
  62 The adnsresfilter utility uses `tsearch' from the C library (a la SVID
  63 and X/Open).  If you don't have tsearch configure will arranges for
  64 adnsresfilter not to be built.  To fix this, install a C library
  65 containing tsearch, such as the GNU C library.  It is best if tsearch
  66 uses an automatically-balancing tree algorithm, like the glibc version
  67 does.  Simple binary trees may perform badly.
  68
  69 If you change the m4 input files in regress/ you may need GNU m4.
  70
  71 You will probably find that GNU Make is required.
  72 Please do not report this as a bug; install GNU Make instead.

  75 SECURITY AND PERFORMANCE - AN IMPORTANT NOTE
  76
  77 adns is not a `full-service resolver': it does no caching of responses
  78 at all, and has no defence against bad nameservers or fake packets
  79 which appear to come from your real nameservers.  It relies on the
  80 full-service resolvers listed in resolv.conf to handle these tasks.
  81
  82 For secure and reasonable operation you MUST run a full-service
  83 nameserver on the same system as your adns applications, or on the
  84 same local, fully trusted network.  You MUST only list such
  85 nameservers in the adns configuration (eg resolv.conf).
  86
  87 You MUST use a firewall or other means to block packets which appear
  88 to come from these nameservers, but which were actually sent by other,
  89 untrusted, entities.
  90
  91 Furthermore, adns is not DNSSEC-aware in this version; it doesn't
  92 understand even how to ask a DNSSEC-aware nameserver to perform the
  93 DNSSEC cryptographic signature checking.
