Configuring ssh not to prompt for password

Question

I have git successfully installed on one of our Red Hat Linux 5 WS servers, and am using it on our Intranet, not outside our firewall.

Currently, I am prompted for a password when I connect, so what steps do I need to take to make sure the server has the correct keys to avoid prompting for a password? I believe this is an issue of making sure the public keys are present. I'm just not sure how to set that up.

Answer 1

Make a keypair, and then copy the public key to the server:

Example:

ssh-keygen -t dsa
ssh-copy-id -i ~/.ssh/id_dsa user@remotehost

Answer 2

OK, it's easy. A is the client, B is the target machine. You login on A with your credentials. You generate the ssh key (if you do have it, ignore that step):

ssh-keygen -t dsa

Defaults are OK. You know have a file ~/.ssh/id_dsa and a ~/.ssh/id_dsa.pub Login on B and execute the commands:

mkdir ~/.ssh
chmod 700 ~/.ssh

Go on A again and scp the key file:

scp ~/.ssh/id_dsa.pub <username_b>@B:~/.ssh/authorized_keys

where is the username of B. Go on B and execute the command:

chmod 600 ~/.ssh/authorized_keys

Now, you should be OK.

Answer 3

Check the /etc/ssh/sshd_config file that the option

PubkeyAuthentication yes is set.

Also, I forgot to answer if you try with the root account. In that case, you need to setup the option PermitRootLogin as

PermitRootLogin without-password
