NAME
rup -- remote status display
SYNOPSIS
rup [host ...]
DESCRIPTION
The rup utility 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 rpc.rstatd(8) daemon must be running on the remote host for this command to work. The rup utility uses an RPC protocol defined in <rpcsvc/rstat.x>.
EXAMPLES
example% rup otherhost otherhost 7:36am up 6 days, 16:45, load average: 0.20, 0.23, 0.18 example%
DIAGNOSTICS

Either the network is excessively congested, or the rpc.rstatd(8) daemon has terminated on the remote host. rup: RPC: Port mapper failure - RPC: Timed out The remote host is not running the portmapper (see rpcbind(8)), and cannot accommodate any RPC-based services. The host may be down.
