The GNU C library contains an NSS module for the Hesiod name service.
Hesiod is a general name service for a variety of applications and is
based on the Berkeley Internet Name Daemon (BIND).
Introduction
============
The Hesiod NSS module implements access to all relevant standard
Hesiod types, which means that Hesiod can be used for the `group',
`passwd' and `services' databases. There is however a restriction.
In the same way that it is impossible to use `gethostent()' to iterate
over all the data provided by DNS, it is not possible to scan the
entire Hesiod database by means of `getgrent()', `getpwent()' and
`getservent()'. Besides, Hesiod only provides support for looking up
services by name and not for looking them up by port. In essence this
means that the Hesiod name service is only consulted as a result of
one of the following function calls:
* getgrname(), getgrgid()
* getpwname(), getpwuid()
* getservbyname()
and their reentrant counterparts.

Configuring your systems to make use the Hesiod name service requires
one or more of the following steps, depending on whether you are
already running Hesiod in your network.

Configuring NSS
---------------
First you should modify the file `/etc/nsswitch.conf' to tell
NSS for which database you want to use the Hesiod name service. If
you want to use Hesiod for all databases it can handle your
configuration file could look like this:
# /etc/nsswitch.conf
#
# Example configuration of GNU Name Service Switch functionality.
#
passwd: db files hesiod
group: db files hesiod
shadow: db files
hosts: files dns
networks: files dns
protocols: db files
services: db files hesiod
ethers: db files
rpc: db files
For more information on NSS, please refer to the `The GNU C Library
Reference Manual'.
Configuring Hesiod
------------------
Next, you will have to configure Hesiod. If you are already running
Hesiod in your network, you probably already have a file named
`hesiod.conf' on your machines (probably as `/etc/hesiod.conf' or

will want to create your own. It should look something like:

Configuring your name servers
-----------------------------
In addition, if you are not already running Hesiod in your network,
you need to create Hesiod information on your central name servers.
You need to run `named' from BIND 4.9 or higher on these servers, and
make them authoritative for the domain `ns.your.domain' with a line in
`/etc/named.boot' reading something like:
primary ns.your.domain named.hesiod
or if you are using the new BIND 8.1 or higher add something to
`/etc/named.conf' like:
zone "ns.your.domain" {
type master;
file "named.hesiod";
};
Then in the BIND working directory (usually `/var/named') create the
file `named.hesiod' containing data that looks something like:
; SOA and NS records.
@ IN SOA server1.your.domain admin-address.your.domain (
40000 ; serial - database version number
1800 ; refresh - sec servers
300 ; retry - for refresh
3600000 ; expire - unrefreshed data
7200 ) ; min
NS server1.your.domain
NS server2.your.domain
; Actual Hesiod data.
libc.group TXT "libc:*:123:gnu,gnat"
123.gid CNAME libc.group
gnu.passwd TXT "gnu:*:4567:123:GNU:/home/gnu:/bin/bash"
456.uid CNAME mark.passwd
Update. * elf/Makefile (tests): Add nodlopen.

where `libc' is an example of a group, `gnu' an example of an user,
and `nss' an example of a service. Note that the format used to
describe services differs from the format used in `/etc/services'.
For more information on `named' refer to the `Name Server Operations
Guide for BIND' that is included in the BIND distribution.
Security
========
Note that the information stored in the Hesiod database in principle
is publicly available. Care should be taken with including vulnerable
information like encrypted passwords in the Hesiod database. There
are some ways to improve security by using features provided by
`named' (see the discussion about `secure zones' in the BIND
documentation), but one should keep in mind that Hesiod was never
intended to distribute passwords. In the origional design
authenticating users was the job of the Kerberos service.
More information
================
For more information on the Hesiod name service take a look at some of
the papers in ftp://athena-dist.mit.edu:/pub/ATHENA/usenix and the
documentation that accompanies the source code for the Hesiod name
service library in ftp://athena-dist.mit.edu:/pub/ATHENA/hesiod.
There is a mailing list at MIT for Hesiod users, hesiod@mit.edu. To
get yourself on or off the list, send mail to hesiod-request@mit.edu.
