rusers 0.17-7.1ubuntu1 (armel binary) in ubuntu jaunty

 The rusers command produces output similar to who, 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 one minute to catch late
 responders.
