.Sh NAME
|
||||
.Nm rup
|
||||
.Nd remote status display
|
||||
.Sh SYNOPSIS
|
||||
.Nm rup
|
||||
.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
|
||||
.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 7:36am up 6 days, 16:45, load average: 0.20, 0.23, 0.18
|
||||

|
||||
.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 accomodate any RPC-based services. The host may be down.
|
||||

.Xr portmap 8 ,
|
||||
.Xr rpc.rstatd 8
|
