ruptime

Ruptime 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 11 minutes are shown as being down.

Options:

-a

Users idle an hour or more are not counted unless the -a flag is given.

-l

Sort by load average.

-r

Reverses the sort order.

-t

Sort by uptime.

-u

Sort by number of users.

The default listing is sorted by host name.
