Hi Johannes, Pdsh is just great :-). I saw this mail below, downloaded, installed and I got the setup and the ssh-trusted connections in just 10 minutes. And the shell is just to cool admin tool Thanks for the link Regards, Pattabhi Raman -----Original Message----- From: linux-cluster-bounces@xxxxxxxxxx [mailto:linux-cluster-bounces@xxxxxxxxxx] On Behalf Of Alex Sent: Thursday, August 28, 2008 7:06 PM To: linux clustering Subject: Re: one click to start httpd on all nodes - possible?

Is not ok at all ... It require rsh server to be installed on our nodes (is anybody using rsh...?) or require ssh v1 which is also disabled by default on all our nodes for security reasons... Finally, will do not do more then one line in a script which i coded in 5 seconds: Stop service: n=3 for i in `seq 1 $n` do ssh -l root node$i /etc/rc.d/init.d/httpd stop && logout; done Start service: n=3 for i in `seq 1 $n` do ssh -l root node$i /etc/rc.d/init.d/httpd start && logout; done I don't think that this is a modern way and elevated method to be used in clustering... If that is all it can redhat cluster v2, i'm afraid is very bad news....
