ruptime
ruptime(1c)ruptime(1c)Name
ruptime - show host status of local machines
Syntax
ruptime [ options ] [ machinename ]
Description
The command gives a status line like for each machine on the local network. If a machinename is given, the status of only the named
machine is given. These status lines 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-a Users idle an hour or more are not counted unless this option is specified.
-d Display only those hosts that are considered down.
-l Sort the status list by load average. If more than one sort option is given, uses the last one.
-r Show only hosts that are up and running.
-t Sort the status list by uptime. If more than one sort option is given, uses the last one.
-u Sort the status list by number of users. If more than one sort option is given, uses the last one.
-nn Show only those hosts with nn or more users.
Restrictions
Because the daemon sends its information in broadcast packets it generates a large amount of network traffic. On large networks the extra
traffic may be objectionable. Therefore, the daemon is disabled by default. To make use of the daemon for both the local and remote
hosts, remove the comment symbols (#) from in front of the lines specifying in the file.
If the daemon is not running on a remote machine, the machine may incorrectly appear to be down when you use the command to determine its
status. See the reference page for more information.
If a system has more than 40 users logged in at once, the number of users displayed by the command is incorrect. Users who login to a
machine after that point fail to increment the user count that appears in the output of the command. This is due to the maximum size limit
of an Ethernet packet, which is 1500 bytes, and the fact that the daemon must broadcast its information in a single packet.
