NAME
ypfiles - Network Information Service Version 2, formerly known as YP
DESCRIPTION
The NIS network information service uses a distributed, replicated
database of ndbm files, in ASCII form, that are contained in the
/var/yp directory hierarchy on each NIS server.
A ndbm database served by the NIS server is called a NIS map. An NIS
domain is a subdirectory of /var/yp that contains a set of NIS maps on
each NIS server.
Standard nicknames are defined in the file /var/yp/nicknames. These
names can be used in place of the full map name in the ypmatch and
ypcat commands. Use the command ypwhich -x to display the current set
of nicknames. Use the command ypwhich -m to display all the available
maps. Each line of the nickname file contains two fields separated by
white space. The first field is the nickname, and the second field is
the name of the map that it expands to. The nickname cannot contain a
dot (.).
SMF Configuration
The configuration for NIS is managed by the following SMF services:
svc:/network/nis/domain
svc:/network/nis/client
svc:/network/nis/server
svc:/network/nis/xfr
svc:/network/nis/passwd
svc:/network/nis/update
svc:/network/nis/domain
Represents the shared configuration used by all NIS components. The
properties managed by this service are contained in the config
property group. Those properties are:
config/domainname
NIS domainname
This is a single valued property containing the IS domainname
(/etc/defaultdomain)
config/ypservers
ypservers Hosts/IP addresses
This is a multi-valued property. Each value contains a server
to which the NIS client is allowed to bind.
config/securenets
securenets network data
This is a multi-valued property. Each value defines the hosts
and networks that are granted access to information in the
served domain.
NIS to LDAP (N2L)
If the /var/yp/NISLDAPmapping configuration file is present, the NIS
server operates in NIS to LDAP (N2L) mode. In this mode, NIS maps are
stored in a new set of DBM files, prepended by the LDAP_ prefix, at
/var/yp/domainname. These files are used as a cache backed by informa‐
tion from an LDAP server. Additional DBM files are created in the same
directory to hold the cache's TTL values.
N2L mode enables NIS clients to be supported in an LDAP environment.
In N2L mode, the old style DBM files, NIS source files, and the
ypmake(8) utility have to role. They are retained to enable easy con‐
version back to the traditional mode, if required.
Converting from N2L to Traditional NIS
When NIS is operating in N2L mode, it uses a new set of NIS maps with
an LDAP_ prefix, based on the contents of the LDAP DIT. The NIS source
files are unused and become out of date. If you wish to convert back to
the traditional NIS mode, the N2L configuration file should be deleted.
The system then returns to using the standard map files. Optionally,
the N2L mode map files, /var/yp/*/LDAP_* can also be deleted.
If you want to run the system in traditional mode with information
based on the DIT, then the NIS source files must be regenerated based
on the N2L maps. To regenerate the NIS source files based on the N2L
maps, run ypmap2src(8).
FILES
/var/yp
Directory containing NIS configuration files.
/var/yp/binding
Stores the information required to bind the NIS client to the NIS
server.
/var/yp/binding/ypdomain/ypservers
Contains the servers to which the NIS client is allowed to bind.
/var/yp/Makefile
Builds the NIS ndbm databases.
/var/yp/nicknames
Nicknames file.
/var/yp/securenets
Defines the hosts and networks that are granted access to informa‐
tion in the served domain. This file is read at startup time by
ypserv and ypxfrd.
/var/yp/ypdomain
Directory containing ndbm databases.
/var/yp/NISLDAPmapping
NIS to LDAP configuration file
/var/yp/*/LDAP_*
NIS to LDAP mode map files

NOTES
All components of NIS, including clients, servers, tools, and program‐
ming interfaces might not be available in a future update of Oracle
Solaris. NIS users should migrate to the LDAP naming service.
