LINODE GPU CLUSTER script Fedora 34

FIX FOR SSH REMOTE TO NOT CLOSE
sshd_config
ClientAliveInterval 60
TCPKeepAlive yes


BUT REALLY ITS SELINUX CLOSING SSH WHEN COMPILING ANYTHING FROM BEING HYPER-SENSITIVE
with enforcing policies by default
use setenforce 0 at your own risk to keep SSH open while compiling projects remotely
I emailed linode support about this matter to adjust all RHEL based customer templates for new
RHEL based deployments by default, to modify enforcing to allow SSH to stay open with a semanage
policy adjustment so enforcing by default with selinux doesnt close ssh sessions from being 
hyper-sensitive
