Hello, everyone,
I’m new here at Rocky Linux and I have a little problem.
We run an HPC simulation cluster. The interconnect of the compute nodes of this cluster is configured unencrypted with rsh. We used Centos 7 in the past. Now we would like to run the cluster with Rocky Linux and i’m wondering how to do the rsh configuration to configure rsh without a password.
You will have to adapt it a little for Rocky Linux 8 or 9, since rsh-server doesn’t exist in the default repositories, but will mean you need to enable the EPEL repository:
dnf install epel-release
At which point you can install rsh and rsh-server that are mentioned in the link provided above. So basically for the client machines:
dnf install rsh
and on the machines acting as servers:
dnf install rsh-server
Once the packages are installed, the remainder of the configuration should be pretty much the same as per the linked document.
