who is logged in to machines on local network
rusers command produces output similar to
who(1), but for the list of hosts or all
machines on the local network. For each host responding to the rusers query,
the hostname with the names of the users currently logged on is printed on
each line. The
rusers command will wait for 30 seconds
to catch late responders.
The options are as follows:
- Print all machines responding even if no one is currently logged in.
- Sort alphabetically by hostname.
- Sort by idle time in ascending order. Unlike other implementations, when
-l flags are
mixed the output is sorted by the idle time of each individual user. If
-l flag is not specified, the idle time for a
machine is considered to be the lowest idle time of a user on that
- Print a long format listing. This includes the user name, host name, tty
that the user is logged in to, the date and time the user logged in, the
amount of time since the user typed on the keyboard, and the remote host
they logged in from (if applicable).
- Sort by number of users logged in.
- If set to a positive integer, output is formatted to the given width in
rusers defaults to the
terminal width, or 80 columns if the output is not a terminal.
- rusers: RPC: Program not registered
- The rpc.rusersd(8) daemon has not
been started on the remote host.
- rusers: RPC: Timed out
- A communication error occurred. Either the network is excessively
congested, or the rpc.rusersd(8)
daemon has terminated on the remote host.
- rusers: RPC: Port mapper failure - RPC: Timed out
- The remote host is not running the portmapper (see
portmap(8)), and cannot accommodate
any RPC-based services. The host may be down.
