ruptime(1tcp)

ruptime -- show host status of local machines

Synopsis

ruptime [-alrtu]

Description

The ruptime command gives a status line like uptime for each machine on the local network; these are formed from packets broadcast by each host on the network once a minute. Machines for which no status report has been received for 5 minutes are shown as being down.

Options

ruptime takes the following options:

-a: Count even those users who have been idle for an hour or more.
-l: Sort the display by load average.
-r: Reverse the sorting order.
-t: Sort the display by up time.
-u: Sort the display by number of users.

Files

/var/spool/rwho/whod.*: data files

Usage

Normally, the listing is sorted by host name, but this order can be changed by specifying one of the options listed below.

Warnings

Note that, for ruptime to work properly, the directory /var/spool/rwho must be created by the system administrator. Given the adverse effect rwho can have on system and network performance, the system administrator must decide whether the benefits of the rwho feature are worth the performance cost.
