Unable to connect using SSH keys

  • 772

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???

linux redhat ssh ssh-keys

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

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

  2. 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.

  3. 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
