yppoll -- ask version of NIS map from NIS server SYNOPSIS
yppoll [-T] [-h host] [-d domain] mapname DESCRIPTION
yppoll asks a NIS server process for the order number and which host is the master server for mapname. The options are as follows: -T Use TCP protocol instead of UDP for request if the -h option is present. -h host Ask the NIS server process running on host for information about mapname. If host is not specified, the server polled is the default server returned by ypwhich(1). -d domain Use the NIS domain domain instead of the default domain as returned by domainname(1). SEE ALSO
domainname(1), ypcat(1), ypmatch(1), ypwhich(1), nis(8), ypbind(8), ypset(8) AUTHORS

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