rup - Show host status of remote machines (RPC version)
Sort the display alphabetically by host name. Sort the
display by load average. Sort the display by up time.
The rup command displays the current time, amount of time
since the system was last started, number of users logged
in, and the load averages for remote machines. It broadcasts
on the local network, and displays the responses it
Normally, the listing is in the order in which responses
are received, but this order can be changed by specifying
one of the options listed in the Flags section. When host
arguments are given, rather than broadcasting, the rup
command queries the list of specified hosts.
A remote host only responds if it is running the rstatd
daemon, which is normally started from the inetd daemon.
Broadcasting does not work through gateways.
Daemons: inetd(8), rpc.statd(8)
