Host Machine not listed.
Hello everyone,
I have a perl script to list all the host machines in my development environment. The script does various other tasks apart from listing the host names in an excel output. The problem is with the listing of host machines. The script lists all the host names except the host on which the script is executed.
For example, we have hosts cc1,cc2,cc3,cc4 and i execute the script on cc1. The output contains cc2,cc3,cc4 except cc1. Similarly i tried executing the script on cc3, the output misses cc3 and prints cc1,cc2,cc4.
I am not sure if i am missing something. Cant we list the host on which we execute a script? Please help, thanks in advance.

rusers
RUSERS(1) BSD General Commands Manual RUSERS(1)
NAME
rusers -- who is logged in to machines on local network
SYNOPSIS
rusers [-al] [host ...]
DESCRIPTION
The rusers command produces output similar to who(1), but for the list of hosts or all machines on the local network. For each host respond-
ing 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.
The following options are available:
-a Print all machines responding even if no one is currently logged in.
-l 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).
DIAGNOSTICS
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 termi-
nated on the remote host.
rusers: RPC: Port mapper failure - RPC: Timed out The remote host is not running the portmapper (see rpcbind(8)), and cannot accommodate any
RPC-based services. The host may be down.
SEE ALSO
rwho(1), users(1), who(1), rpc.rusersd(8), rpcbind(8)
HISTORY
The rusers command appeared in Sun-OS.
BUGS
The sorting options are not implemented.
