copied id_rsa.pub-host to client  (in /root/.ssh/PUB)

on client:

/usr/bin/ssh-keygen -b 2048 -t rsa
/usr/bin/cp id_rsa.pub id_rsa.pub-client

cat id_rsa.pub-host >> authorized_keys
cat id_rsa.pub-client >> authorized_keys

scp id_rsa.pub-client host:/root/.ssh/

on host:
cat id_rsa.pub-client >> authorized_keys


test:
	ssh client w

works... :)  (from host)
