3 | 1. Read the security note below. |
4 | |
5 | 2. Standard GNU package build process: |
bef232ae |
6 | $ ./configure [--disable-dynamic] [--prefix=... ...] |
95ecb688 |
7 | $ make |
8 | # make install |
9 | |
bef232ae |
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 |
95ecb688 |
17 | |
e32d0f9e |
18 | The following platforms have been tested at at least some point and |
19 | should work - please report if they don't: |
5c05c458 |
20 | adns version OS |
bef232ae |
21 | 1.0 Linux glibc 2.1 (actually tested on Debian 2.2) |
22 | 1.0 Solaris 2.6, 2.7, 2.8 [3] |
57700a3b |
23 | 1.0 FreeBSD 3.2, 4.0 (no poll(2), so no adnsresfilter) |
bef232ae |
24 | The following work, but only with --disable-dynamic: |
57700a3b |
25 | 1.0 IRIX 6.5 *not* with GCC [1], [2] |
26 | 1.0 AIX 4.1.5 |
8e26a971 |
27 | 1.0 HP-UX 10.20, 11.00 |
5c05c458 |
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. |
bef232ae |
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. |
d0ac9ea0 |
36 | [3] Dynamically linked, needs some help to find libadns.so.1.0. |
e32d0f9e |
37 | |
38 | The following platforms are known to be deficient and will not work: |
bef232ae |
39 | Solaris 2.5 Lacks vsnprintf - install glibc ? |
40 | TruUnix64 (DEC UNIX 4.0f) Lacks vsnprintf - install glibc ? |
e32d0f9e |
41 | Please don't report these problems unless you have a nice, |
bef232ae |
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 |
5c05c458 |
49 | system. Systems which are neither GNU nor UNIX are not supported. |
e32d0f9e |
50 | |
bef232ae |
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). |
95ecb688 |
57 | |
5c05c458 |
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 | |
9a09fa18 |
62 | The adnsresfilter utility uses `tsearch' from the C library (a la SVID |
bef232ae |
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 | |
5c05c458 |
69 | If you change the m4 input files in regress/ you may need GNU m4. |
70 | |
e39ec089 |
71 | You will probably find that GNU Make is required. |
bef232ae |
72 | Please do not report this as a bug; install GNU Make instead. |

75 | SECURITY AND PERFORMANCE - AN IMPORTANT NOTE |
76 | |
0bd55bf5 |
77 | adns is not a `full-service resolver': it does no caching of responses |
2b61beb8 |
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. |
