Hi,
	Not related to pdsh but since I already have passwordless ssh I just  
use that to check the nodes for things:

[root at host ~]# sshem-xserv uptime
xserv0001: 16:14  up 13 mins, 0 users, load averages: 0.04 0.02 0.00
xserv0002: 16:14  up 13 mins, 0 users, load averages: 0.01 0.03 0.00
xserv0003: 16:14  up 5 mins, 0 users, load averages: 0.03 0.12 0.07
xserv0004: 16:14  up 13 mins, 0 users, load averages: 0.12 0.04 0.01
xserv0005: 16:14  up 13 mins, 0 users, load averages: 0.02 0.04 0.00
xserv0006: 16:14  up 13 mins, 0 users, load averages: 0.13 0.04 0.01
xserv0007: 16:14  up 13 mins, 0 users, load averages: 0.09 0.08 0.05

[root at host ~]# cat /usr/local/global/bin/sshem-xserv
#!/bin/csh

foreach host ( `cat /usr/local/global/etc/clusters-xserv` )
	echo -n $host": "
	ssh $host $*
end

[root at host ~]#


Similarly, I also have a corresponding scpem script to copy config  
files from the head node out to the client nodes.

[root at host ~]# cat /usr/local/global/bin/scpem-xserv
#!/bin/csh

  foreach host ( `cat /usr/local/global/etc/clusters-xserv` )

	echo -n $host": "
	scp $1 root\@$host\:$1
end
[root at host ~]#

With this setup I can have different sshem/scpem scripts for each of  
the different architecture types of machines we have. Hope this helps,

-Steve
