Greetings,
I have a question concerning security on an system I am
building:
It is (supposed to become) a Beowulf Linux Cluster w. Suse
8.0 installed on each node and master.
To run programs on my cluster I need to enable passwordless
remote command execution with rsh, so I cant switch to ssh.
I have enabled the rsh-Deamon on all computers.
It has two NICs, one connected to the cluster's switch, the
other to the internet.
My question concerns the master:
In the masters hosts.deny the entry
ALL : ALL
was placed and in the hosts.allow the entry
ALL : (some IPs I can trust)
in hosts.equiv all the cluster nodes were placed.

Sorry, my clumsy finders clicked "send" before I could stop
them :-)
Here is my question:
Is my setup of the master (the one with 2 NICs) reasonable
secure?
IMHO, that is as far as I understand the man pages, no one
except the trusted IPs I entered can use rsh on my cluster.
Is that right or are there things I should change/improve?
Kind regards,
Thomas
