i have two hosts

H1 with ip=10.10.10.15 , OS=Windows Server 2016 and username=administrator

H2 with ip=10.10.10.16 , OS=Centos7 and username=user

I attempt to create a ssh connection between H1 and H2.

I mean, when i tape from the windows machine : ssh user@10.10.1.16 , i don’t need to tape the password of user and directly i have a remote access

After generate the key with ssh-keygen , i try with ssh-copy-id -i id_rsa.pub user@10.10.1.16 and i enter the password

/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: ".ssh/id_rsa.pub" /usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed /usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys user@10.10.10.16's password:   Number of key(s) added: 1  Now try logging into the machine, with:   "ssh 'user@10.10.10.16'" and check to make sure that only the key(s) you wanted were added. 

but the console request always the password of user

Is there some way to resolve that ?
