Unable to connect using SSH keys

Question

I am trying to connect to my linux server using the following:

ssh-keygen -t rsa

I then do:

cat ~/.ssh/id_rsa.pub | ssh myusername@myserver_ip 'cat >> .ssh/authorized_keys'

I then go to my remote server and see that a "authorized_keys" file has been created. However when i try doing, "ssh myusername@myserver_ip", it is still prompting me for a password?

Why???

Try with `ssh -vvv myusername@myserver_ip` to see more details. — Janne Pikkarainen, May 30 '12 at 07:46
You can check /var/log/auth.log or /var/log/secure on the server side. You can check your sshd configuration : RSAAuthentication yes, PubkeyAuthentication yes. — Christophe Drevet, May 30 '12 at 10:01

Verify the ownership and permissions on your ~/.ssh directory and its contents:

$ sudo chown -R <user> ~/.ssh
$ chmod 700 ~/.ssh
$ chmod 600 ~/.ssh/*

You may need to check the sshd_config to ensure that these are enabled:

RSAAuthentication yes
PubkeyAuthentication yes

Once those are set to 'yes' then you will need to restart ssh.

Ok First of all make sure you have this options enabled in your /etc/ssh/sshd_config

    RSAAuthentication yes
    PubKeyAuthentication yes
    AuthorizedKeysFlle %h/.ssh/authorized_keys

Second, in order to copy the key from ServerA(where you generated the key) to ServerB(where you want to log in) use the following command:

    ssh-copy-id your_username@your_serverB_Ip

If by any chance ServerA doesnt have ssh-copy-id command, in ServerA copy the first line of your key WITHOUT the last 2 characters, then paste it in the ServerB Authorized_Keys file. After that type yourself the missing characters from the line you just copied and the first one from line 2, this will prevent adding a "new line" between the first and second line of the key while pasting it from ServerA to ServerB. Repeat with the 3rd line
