NAME
rup — show host status of local machines (RPC version)
SYNOPSIS
rup
[-h]
[-l]
[-t]
[host ...]
DESCRIPTION
rup
gives a status similar to
uptime
for remote machines.
It broadcasts on the local network
and displays the responses it receives.
Though the listing is normally in the order responses are received,
the order can be changed by using command-line options.
The broadcast process takes about two minutes.
When
host
arguments are given, instead of broadcasting,
rup
only queries the list of specified hosts.
A remote host only responds if it is running the
rstatd
daemon (see
rstatd(1M)).
Options
rup
recognizes the following command-line options:
- -h
Sort the display alphabetically by host name.
- -l
Sort the display by load average.
- -t
Sort the display by up time.
WARNINGS
Broadcasting does not work through gateways; therefore,
rup
does not report information
about machines that are reachable only through gateways.
DIAGNOSTICS
The exit code of
rup
is the number of errors (eg. bad host names) encountered;
zero for success.
