man rup (Commandes) - remote uptime display
NAME
rup - remote uptime display
SYNOPSIS
rup { -u | -v | hosts ... }
DESCRIPTION
rup displays a summary of the current status of a particular
host or all hosts on the local network.
The output shows how long the system has been up, the number of
users currently on the system (if the system is running the current
version of rpc.rstatd(8)), and the load averages.
The load average numbers give the number of jobs in the run queue
averaged over 1, 5 and 15 minutes.
The rpc.rstatd(8) daemon must be running on the remote host
for this command to work.
rup uses an RPC protocol defined in /usr/include/rpcsvc/rstat.x
COMMAND LINE OPTIONS
- -v
- prints the current version of rup and exits
- -u
- broadcasts for infornmation from machines capable of returning users information implemented in the newest version of rpc.rstatd
DIAGNOSTICS
- rup: RPC: Program not registered
- The rpc.rstatd(8) daemon has not been started on the remote host.
- rup: RPC: Timed out
- A communication error occurred. Either the network is excessively congested, or the rpc.rstatd(8) daemon has terminated on the remote host.
- rup: RPC: Port mapper failure - RPC: Timed out
- The remote host is not running the portmapper (see rpc.rstatd(8)) and cannot accomodate any RPC-based services. The host may be down.
