Shows the status of a remote host on the local network.
/usr/bin/rup [ -h | -l | -t ] [ Host ... ]
The rup command displays the status of a remote host by broadcasting on the local network and then displaying the responses it receives. Specify a flag if you want to sort the output. If you do not specify a flag, the rup command displays responses in the order they are received. If you specify multiple hosts on the command line, the rup command ignores any flags and displays output in the order you specified the hosts. You must use the sort command to sort the output.
In addition, when you provide a value for the Host parameter, the rup command queries the hosts you specify, rather than broadcasting to all hosts. A remote host responds only if it is running the rstatd daemon, which is normally started from the inetd daemon.
- Broadcasting does not work through gateways. Therefore, if you do not specify a host, only hosts on your network can respond to the rup command.
- Load-average statistics are not kept by the kernel. The load averages are always reported as 0 (zero) by this command.
|-h||Sorts the display alphabetically by host name.|
|-l||Sorts the display by load average.|
|-t||Sorts the display by length of runtime on the network.|
/usr/bin/rup brutusIn this example, the rup command displays the status of the host named brutus.
|/etc/inetd.conf||Defines how the inetd daemon handles Internet service requests.|
