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.

ruptime - Displays the status of each host on a network SYNOPSIS
ruptime [-ar] [-l | -t | -u] ruptime [-ar] [-l | -t | -u] [machinename] The ruptime command displays the status of each host on a local network that is running the rwhod daemon. If machinename is specified, only the status of that machine is displayed. OPTIONS
Includes all users. Without this option, users whose sessions are idle an hour or more are not included. Sorts the list by the load aver- age over 5-, 10-, and 15-minute intervals prior to a server's transmission. The load averages are multiplied by 10 to represent the value in decimal format. Reverses the sort order. Sorts the list by the length of uptime. Sorts the list by the number of users. DESCRIPTION
The status lines are sorted by hostname unless the -l, -t, or -u option is indicated. The status information is provided in packets broad- cast once every 3 minutes by each network host running rwhod. Any activity (such as the power to a host being turned on or off) that takes place between broadcasts is not reflected until the next broadcast. Hosts for which no status information is received for 11 minutes are reported as down. EXAMPLES
To get a status report on the hosts on the local network, enter: $ ruptime Information similar to the following is displayed: host1 up 5:15, 4 users, load 0.09, 0.04, 0.04 host2 up 7:45, 3 users, load 0.08, 0.07, 0.04 host3 up 2:28, 0 users, load 0.01, 0.02, 0.03 host4 up 3+01:44, 1 user, load 0.01, 0.02, 0.03 host7 up 7:43, 1 user, load 0.06, 0.12, 0.11 (Output may be formatted differently on your system.) To get a status report sorted by load average, enter: $ ruptime -l Information similar to the following is displayed: host2 up 7:45, 3 users, load 0.08, 0.07, 0.04 host1 up 5:18, 4 users, load 0.07, 0.07, 0.04 host7 up 7:43, 1 user, load 0.06, 0.12, 0.11 host3 up 2:28, 0 users, load 0.01, 0.02, 0.03 host4 up 3+01:44, 1 user, load 0.01, 0.02, 0.03 (Output may be formatted differently on your system.)
