NAME
ypset -- tell ypbind(8) which YP server process to use SYNOPSIS
ypset [-h host] [-d domain] server DESCRIPTION
Ypset tells the ypbind(8) process on the current machine which YP server process to communicate with. If server is down or is not running a YP server process, it is not discovered until a YP client process attempts to access a YP map, at which time ypbind(8) tests the binding and takes appropriate action. Ypset is most useful for binding a YP client that is not on the same broadcast network as the closest YP server, but can also be used for debugging a local network's YP configuration, testing specific YP client programs, or binding to a specific server when there are many servers on the local network supplying YP maps. The options are as follows: -h host Set the YP binding on host instead of the local machine. -d domain Use the YP domain domain instead of the default domain as returned by domainname(1). SEE ALSO
domainname(1), ypbind(8), ypcat(1), ypmatch(1), yppoll(8), ypwhich(1), yp(8) AUTHOR
