+.Sh NAME
+.Nm rup 
+.Nd remote status display
+.Sh SYNOPSIS
+.Nm rup 
+.Op Fl dhlt
+.Op Ar host ...
+.Sh DESCRIPTION
+.Nm rup
+displays a summary of the current system status of a particular
+.Em host 
+or all hosts on the local network.
+The output shows the current time of day, how long the system has
+been up,
+and the load averages.
+The load average numbers give the number of jobs in the run queue
+averaged over 1, 5 and 15 minutes.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl d
+For each host, report what it's local time is.
+This is useful for checking time synchronization on a network.
+.It Fl h
+Sort the display alphabetically by host name.
+.It Fl l
+Sort the display by load average.
+.It Fl t
+Sort the display by up time.
+.El
+.Pp
+The
+.Xr rpc.rstatd 8
+daemon must be running on the remote host for this command to
+work.
+.Nm rup
+uses an RPC protocol defined in /usr/include/rpcsvc/rstat.x.
+.Sh EXAMPLE
+.Bd -unfilled -offset indent -compact
+example% rup otherhost
+otherhost      up 6 days, 16:45,  load average: 0.20, 0.23, 0.18
+example%
+.Ed
+.Sh DIAGNOSTICS
+.Bl -tag -width indent
+.It rup: RPC: Program not registered
+The
+.Xr rpc.rstatd 8
+daemon has not been started on the remote host.
+.It rup: RPC: Timed out
+A communication error occurred.  Either the network is
+excessively congested, or the
+.Xr rpc.rstatd 8
+daemon has terminated on the remote host.
+.It rup: RPC: Port mapper failure - RPC: Timed out
+The remote host is not running the portmapper (see
+.Xr portmap 8 ),
+and cannot accommodate any RPC-based services.  The host may be down.
+.El
+.Sh SEE ALSO
+.Xr ruptime 1 ,
+.Xr portmap 8 ,
+.Xr rpc.rstatd 8
+.Sh HISTORY
+The
+.Nm rup
+command
+appeared in
+.Tn SunOS .
