Network Information Service (NIS) B.11.31.04 Administrator's Guide

• Starts the ypserv daemon if it is not already running on both the master and the
slave servers.
• Starts ypxfrd if it is not already running on both the master and the slave servers.
The nis.client script is executed at run level 2 on the systems configured as NIS
client. This script performs the following tasks:
• Starts the rpcbind daemon if it is not already running.
• Sets the domainname.
• Starts ypbind if it is not already running.
• Starts keyserv if it is not already running.
Features in NIS
This section discusses the new NIS features supported on the HP-UX 11i v3 operating
system:
• DNS Forwarding Mode
DNS forwarding mode can be enabled using the -d option with the NIS server
daemon, ypserv:
# ypserv -d
Alternatively, you can modify the YPSERV_OPTIONS entry in the /etc/
rc.config.d/namesvrs file, to enable the DNS forwarding mode
YPSERV_OPTIONS="-d"
For detailed procedure on how to enable the DNS forwarding mode, see “Enabling
the DNS Forwarding Mode ” (page 40).
When you run the NIS server in the DNS forwarding mode, if the ypserv daemon
does not find the host or ipnode entry in the NIS host or ipnode map, ypserv
automatically contacts the configured DNS server. This feature is useful in
configurations where certain host or ipnode entries are present in the NIS repository
and a different set of entries are present in the DNS repository. For example, if
you want to store the host information for host X in NIS and host Y in DNS. If the
hosts entry in the /etc/nsswitch.conf file contains only nis (hosts: nis),
the information for host Y is retrieved even though dns is not specified in the hosts
entry.
With DNS forwarding mode, retrieval from DNS is done transparently, without
changing the /etc/nsswitch.conf configuration file.
For information about the /etc/nsswitch.conf configuration file, see NFS

• Shadow Password Mode
The NIS password daemon, rpc.yppasswdd, supports the HP-UX shadow
password mode.
