-INSTALLATION INSTRUCTIONS for ADNS
+INSTALLATION INSTRUCTIONS for GNU ADNS
- $ ./configure
+1. Read the security note below.
+
+2. Standard GNU package build process:
+ $ ./configure [--disable-dynamic] [--prefix=... ...]
$ 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.
+Unfortunately, there is no comprehensive documentation yet. For now,
+use the comments in the public header file adns.h, and for the C
+programs their usage messages. If you find this information
+ambiguous, incomplete or wrong, please report it as a bug.
+
+
+TESTED PLATFORMS
+
+The following platforms have been tested at at least some point and
+should work - please report if they don't:
+ adns version OS
+ 1.0 Linux glibc 2.1 (actually tested on Debian 2.2)
+ 1.0 Solaris 2.6, 2.7, 2.8 [3]
+ 1.0 FreeBSD 3.2, 4.0 (no poll(2), so no adnsresfilter)
+The following work, but only with --disable-dynamic:
+ 1.0 IRIX 6.5 *not* with GCC [1], [2]
+ 1.0 AIX 4.1.5
+ 1.0 HP-UX 10.20, 11.00
+ 1.1 Darwin (kernel 7.5.1)
+Later versions of the same OS should work too. Usually entries in
+this table mean adns passes its own regression test, when compiled
+with GCC, and appears to install and run correctly. If you have more
+information for this table please let me know.
+
+Notes/known problems:
+ [1] IRIX 6.5 inet_ntoa seems to break with GCC.
+ [2] The SGI IRIX compiler produces many spurious warnings.
+ [3] Dynamically linked, needs some help to find libadns.so.1.0.
+The following platforms are known to be deficient and will not work:
+ Solaris 2.5 Lacks vsnprintf - install glibc ?
+ TruUnix64 (DEC UNIX 4.0f) Lacks vsnprintf - install glibc ?
+Please don't report these problems unless you have a nice,
+straightforward solution or workaround for them. (I don't consider
+including a `vsnprintf' implementation nice, so don't send me one.)
+
+
+PORTABILITY INFORMATION
You will find that adns requires a reasonably standard and up to date
-system.
+system. Systems which are neither GNU nor UNIX are not supported.
+
+The build system assumes by default that you have ELF shared
+libraries, and that the directory in which libadns.so.1 will be
+installed is on your dynamic library search path. If your system
+doesn't have ELF shared libraries then dynamic linking is not
+supported by adns. Use the --disable-shared configure option.
+Please don't send me patches to use libtool (which I dislike).
+
+Compilers other than GNU C should work, but are not well-tested. Feel
+free to send me patches to improve the situation. However, the
+Makefiles only know how to use GCC to make dynamic libraries.
+
+The adnsresfilter utility uses `tsearch' from the C library (a la SVID
+and X/Open). If you don't have tsearch configure will arranges for
+adnsresfilter not to be built. To fix 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.
-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.
+If you change the m4 input files in regress/ you may need GNU m4.
You will probably find that GNU Make is required.
+Please do not report this as a bug; install GNU Make instead.
+
+
+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.
