Hi Robert

I have made the appropriate entries in shosts files also, but still on
executing it asks me for passwords :(
Thanks n Regards

Hi All
I am trying to setup a demo beowulf cluster.
I just have two nodes a master and a slave, both have Fedora Core 2
installed on it.
I searched on the net, found many HowTo's. I am following the one
OSTG, don't know
who has written it. It explains how to setup the head node and the
slave node separately and extensively.
But I am stuck at the place at which the HowTo says that the services
rlogin and rexec should be up.
When I try to add these services by chkconfig, it throws error saying
that service rlogin/rexec does not support
chkconfig.
Can someone help me out on how to proceed now.
Thanks in advance
Swati
Several ways, but the "best" way in the short run is probably to use
ssh/sshd. That should be already installed, if not, it is a "yum
install ssh\*" away. ssh supplants the need for both of the
rlogin/rexec services indefinitely and is secure enough not to be a
problem (given your level of (in)experience at network services) until
much later, when your needs and skills have grown.
You can use ssh for pretty much anything you'd use the r-services for
including as a vehicle for trying out MPI or PVM or socket-based
parallel code.
