dnf -y install ansible mc net-tools openssh-server openssh-clients passwdqc cracklib-dicts shadow-utils

systemctl enable sshd
systemctl start sshd

useradd -b /specialusers ansibleuser

cat /etc/selinux/config | sed s/"$SELINUX=enforcing"/"SELINUX=disabled"/g > /etc/selinux/config_xxx \cp /etc/selinux/config_xxx /etc/selinux/config \rm /etc/selinux/config_xxx reboot

sshpass -p "$passwd_value" ssh-copy-id -o "StrictHostKeyChecking accept-new" ansibleuser@COMPUTERNAME
