rup(1C)

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.

     Normally, the listing is in the order that responses are received, but
     this order can be changed by specifying one of the options listed below.

     When host arguments are given, rather than broadcasting rup will only
     query the list of specified hosts.

     A remote host will only respond if it is running the rstatd daemon, which
     is normally started up from inetd(1M).

OPTIONS
     -h   Sort the display alphabetically by host name.

     -l   Sort the display by load average.

     -t   Sort the display by the length of time the systems have been up.

SEE ALSO

BUGS
     Broadcasting does not work through gateways.
