rup - show host status of remote machines (RPC version)
rup [-hlt] [host]...
rup gives a status similar to uptime(1) for remote machines. If no host arguments are specified, it broadcasts on the local network, and displays the responses it receives.
When host arguments are given, rather than broadcasting rup will only query the list of specified hosts.
Normally, the listing is in the order that responses are received, but this order can be changed by specifying one of the options listed below.
A remote host will only respond if it is running the rpc.rstatd(8) daemon, which is normally started up from inetd(8) under the service identifier svc:/network/rpc/rstat:default. This service is disabled by default on Solaris 10 systems with a secure by default configuration and on all Solaris 11 systems, and must be enabled by an administrator in order for a host to respond to rup queries.
If no name can be found for a host via the hosts(5) name service, rup displays a numeric IP address for the host.
Sort the display alphabetically by host name.
Sort the display by load average.
Sort the display by up time.
See attributes(7) for descriptions of the following attributes:
|
ruptime(1), attributes(7), inetd(8), rpc.rstatd(8)
Broadcasting does not work through gateways.
The rup command, including support for the options –h, –l, and –t, has been present since the initial release of Solaris.
