rup
RUP(1) BSD General Commands Manual RUP(1)NAME
rup -- remote status display
SYNOPSIS
rup [-dhlt] [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 aver-
aged over 1, 5 and 15 minutes.
The following options are available:
-d For each host, report what it's local time is. This is useful for checking time synchronization on a network.
-h Sort the display alphabetically by host name.
-l Sort the display by load average.
-t Sort the display by up time.
The rpc.rstatd(8) 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.
EXAMPLES
example% rup otherhost
otherhost up 6 days, 16:45, load average: 0.20, 0.23, 0.18
example%
DIAGNOSTICS
rup: RPC: Program not registered
The rpc.rstatd(8) 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.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.
