INSTALLATION INSTRUCTIONS for GNU ADNS
|
|
|
|
1. Read the security note below.
|
|
|
|
2. Standard GNU package build process:
|
|
$ ./configure [--disable-dynamic] [--prefix=... ...]
|
|
$ make
|
|
# make install
|
|
|
|
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
|
|
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. 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.
|
|
|
|
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.
