Introduction
|
||
|
|
||
|
ISC's libbind provides the standard resolver library,
|
||
|
along with header files and documentation, for communicating
|
||
|
with domain name servers, retrieving network host entries
|
||
|
from /etc/hosts or via DNS, converting CIDR network addresses,
|
||
|
perform Hesiod information lookups, retrieve network entries
|
||
|
from /etc/networks, implement TSIG transaction/request
|
||
|
security of DNS messages, perform name-to-address and
|
||
|
address-to-name translations, utilize /etc/resolv.conf
|
||
|
for resolver configuration.
|
||
|
|
||
|
It contains many of the same historical functions and headers
|
||
|
included with many Unix operating systems.
|
||
|
|
||
|
Originally written for BIND 8, it was included in BIND 9 as
|
||
|
optionally-compiled code through release 9.5. It has been
|
||
|
removed from subsequent releases of BIND 9 and is now
|
||
|
provided as a separate package.
|
||
|
|
||
|
Building
|
||
|
|
||
|
The libbind library requires a system with an ANSI C compiler
|
||
|
and basic POSIX support.
|
||
|
|
||
|
To build, just
|
||
|
|
||
|
./configure
|
||
|
make
|
||
|
|
||
|
Several environment variables that can be set before running
|
||
|
configure will affect compilation:
|
||
|
|
||
|
CC
|
||
|
The C compiler to use. configure tries to figure
|
||
|
out the right one for supported systems.
|
||
|
|
||
|
CFLAGS
|
||
|
C compiler flags. Defaults to include -g and/or -O2
|
||
|
as supported by the compiler.
|
||
|
|
||
|
STD_CINCLUDES
|
||
|
System header file directories. Can be used to specify
|
||
|
where add-on thread or IPv6 support is, for example.
|
||
|
Defaults to empty string.
|
||
|
|
||
|
STD_CDEFINES
|
||
|
Any additional preprocessor symbols you want defined.
|
||
|
Defaults to empty string.
|
||
|
|
||
|
Possible settings:
|
||
|
Change the default syslog facility of named/lwresd.
|
||
|
-DISC_FACILITY=LOG_LOCAL0
|
||
|
Enable DNSSEC signature chasing support in dig.
|
||
|
-DDIG_SIGCHASE=1 (sets -DDIG_SIGCHASE_TD=1 and
|
||
|
-DDIG_SIGCHASE_BU=1)
|
||
|
Disable dropping queries from particular well known ports.
|
||
|
-DNS_CLIENT_DROPPORT=0
|
||
|
Sibling glue checking in named-checkzone is enabled by default.
|
||
|
To disable the default check set. -DCHECK_SIBLING=0
|
||
|
named-checkzone checks out-of-zone addresses by default.
|
||
|
To disable this default set. -DCHECK_LOCAL=0
|
||
|
Enable workaround for Solaris kernel bug about /dev/poll
|
||
|
-DISC_SOCKET_USE_POLLWATCH=1
|
||
|
The watch timeout is also configurable, e.g.,
|
||
|
-DISC_SOCKET_POLLWATCH_TIMEOUT=20
|
||
|
|
||
|
LDFLAGS
|
||
|
Linker flags. Defaults to empty string.
|
||
|
|
||
|
The following need to be set when cross compiling.
|
||
|
|
||
|
BUILD_CC
|
||
|
The native C compiler.
|
||
|
BUILD_CFLAGS (optional)
|
||
|
BUILD_CPPFLAGS (optional)
|
||
|
Possible Settings:
|
||
|
-DNEED_OPTARG=1 (optarg is not declared in <unistd.h>)
|
||
|
BUILD_LDFLAGS (optional)
|
||
|
BUILD_LIBS (optional)
|
||
|
|
||
|
"make install" will install the library. By default, installation
|
||
|
is into /usr/local, but this can be changed with the "--prefix"
|
||
|
option when running "configure".
|
||
|
|
||
|
To see additional configure options, run "configure --help".
|
||
|
|
||
|
If you need to re-run configure please run "make distclean" first.
|
||
|
This will ensure that all the option changes take.
|
||
|
|
||
|
Notes on Usage
|
||
|
|
||
|
- Installing both libbind and BIND 9 on the same system
|
||
|
will produce two incompatible header files with similar
|
||
|
names: $PREFIX/include/isc/list.h (from BIND 9) and
|
||
|
$PREFIX/include/bind/isc/list.h (from libbind). When
|
||
|
compiling code against libbind, be sure to set -I flags
|
||
|
appropriately.
|
||
|
|
||
|
Documentation
|
||
|
|
||
|
Man pages for libbind routines, in *roff and plaintext format,
|
||
|
are included with the release.
