37.Os
38.Sh NAME
39.Nm ypset
40.Nd tell
41.Xr ypbind 8
42which YP server process to use
43.Sh SYNOPSIS
44.Nm
45.Op Fl h Ar host
46.Op Fl d Ar domain
47.Ar server
48.Sh DESCRIPTION
49The
50.Nm
51utility tells the
52.Xr ypbind 8
53process on the current machine which YP server process to communicate with.
54If
55.Ar server
56is down or is not running a YP server process, it is not discovered until
57a YP client process attempts to access a YP map, at which time
58.Xr ypbind 8
59tests the binding and takes appropriate action.
60.Pp
61The
62.Nm
63utility
64is most useful for binding a YP client that is not on the same broadcast
65network as the closest YP server, but can also be used for debugging
66a local network's YP configuration, testing specific YP client
67programs, or binding to a specific server when there are many servers on
68the local network supplying YP maps.
69.Pp
70The options are as follows:
71.Bl -tag -width indent
72.It Fl h Ar host
73Set the YP binding on
74.Ar host
75instead of the local machine.
76.It Fl d Ar domain
77Use the YP domain
78.Ar domain
79instead of the default domain as returned by
80.Xr domainname 1 .
