NAME

rup - remote status display

SYNOPSIS

rup [-dshlt ] [host ... ]

DESCRIPTION

rup displays a summary of the current system status of a particular 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.

The following options are available:

-d

For each host, report what its local time is. This is useful for checking time syncronization on a network.

-s

Print time data in seconds (seconds of uptime or seconds since the epoch), for scripts.

-h

Sort the display alphabetically by host name.

-l

Sort the display by load average.

-t

Sort the display by up time.

The rpc.rstatd8 daemon must be running on the remote host for this command to work. rup uses an RPC protocol defined in /usr/include/rpcsvc/rstat.x.

EXAMPLE

 example% rup otherhost
 otherhost      up 6 days, 16:45,  load average: 0.20, 0.23, 0.18

DIAGNOSTICS

rup: RPC: Program not registered

The rpc.rstatd8 daemon has not been started on the remote host.

rup: RPC: Timed out

A communication error occurred. Either the network is excessively congested, or the rpc.rstatd8 daemon has terminated on the remote host.

rup: RPC: Port mapper failure - RPC: Timed out

The remote host is not running the portmapper (see portmap(8)), and cannot accomodate any RPC-based services. The host may be down.
