All the machines are FC8, the host and all the nodes. I'm just setting this up for the first time and no, none of the machines are working with ypbind - well with the exception of the head node.
There is no /etc/defaultdomain because the startup script assigns the domains to each machine. I can try creating this file anyway but I don't believe it would affect anything.
yp.conf =
domain node1 server 192.168.0.2
The domain name changes respectively for each node.
Yup the head node is there, heres /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 node1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
192.168.0.2 head.node
#192.168.0.253 node1
192.168.0.252 node2
192.168.0.251 node3
On the nodes ypwhich returns:
[root@node1 ~]# ypwhich
ypwhich: Can't communicate with ypbind
[root@node1 ~]#
which is to be expected because ypbind wont start
On the master ypbind is running fine so it returns:
[root@head home]# ypwhich
head.node
[root@head home]#
The nodes respectively show something similar to this:
[root@node1 ~]# domainname
node1
[root@node1 ~]#
And the master shows:
[root@head home]# domainname
head.node
[root@head home]#

5. Solaris
I have built this Solaris 10 server, uses NIS. When the server starts up, two instances of ypbind start. This prevents the server from binding to any domain. The SMF in turn prevents any other network services (sshd and the like) from starting up.
Has anyone seen this problem before? (0 Replies)

ypset(8) System Manager's Manual ypset(8)
NAME
ypset - bind ypbind to a particular NIS server
SYNOPSIS
ypset [ -d domain ] [ -h hostname ] server
DESCRIPTION
In order to run ypset, ypbind must be initiated with the -ypset or -ypsetme options. See ypbind(8). ypset tells ypbind to get NIS ser-
vices for the specified domain from the ypserv(8) process running on server.
In cases where several hosts on the local net are supplying NIS services, it is possible for ypbind to rebind to another host even while
you attempt to find out if the ypset operation succeeded. For example, you can type:
example% ypset host1
example% ypwhich
host2
which can be confusing. This is a function of the NIS subsystem's attempt to know always a running NIS server, and occurs when host1 does
not respond to ypbind because it is not running ypserv (or is overloaded), and host2, running ypserv, gets the binding.
Server indicates the NIS server to bind to, and must be specified as a name or an IP address. This will work only if the node has a cur-
rent valid binding for the domain in question, and ypbind has been set to allow use of ypset. In most cases, server should be specified
as an IP address.
OPTIONS
-d domain
Specify a domain other than the default domain as returned by domainname(8).
-h hostname
Set the NIS binding on host hostname
instead of the local machine.
