The following options are available:

NOTES
Ruptime shows a remote sytem up only if rwhod(1M) is running on both the local machine and the remote machine, and they both are on the same physical network or if their bridge/router passes rwhod broadcasts between subnets, and if the remote system has been up long enough to generate its first rwho broadcast.
