If you want to use scoutd with -g option, you must set SCBDSERV environment
variable to access scoreboard.
(If you set this variable to /etc/score.conf, /etc/rc.d/init.d/scoutd
read this file.)
If you want to use -f option, this host must be official name.

In both case, you must add the host to run scout command in the group or file.

If you check scoutd, you can use sceptic.
For example:
    server% ceptic -v -g pcc
    comp3.pccluster.org: OK
    comp2.pccluster.org: OK
    comp1.pccluster.org: OK
    comp0.pccluster.org: scping FAILED
    comp0.pccluster.org: OK
    All host responding.
    server%
This means comp0 don't access scoutd from server, but rsh iis ok.

Also you can use scping to more daatail.
    server% scping  comp0.pccluster.org
    Connection closed.
This meaqns, scout is running, but you can't access via server.
    server% scping  comp0.pccluster.org
    Unable to make connection.
This means scoutd is not running.
