authorized-keys

I am ssh-ing from server1 to server2 . I generated the id_rsa & id_rsa.pub files. If I ssh to mike@server2 it works fine, but ssh to john@server2 does not work without password. Both mike & john home directories contain ".ssh" which is chmod 700 and that folder contains "authorized_keys" containing only the contents of the id_rsa.pub file generated previously (and is chmod 600). Contents of both are the same. Server 1: Linux x86_64 x86_64 x86_64 GNU/Linux Server 2: AIX 5.3.0.0 64-bit Command 1, User Mike (works with no password): ssh -v -n -o StrictHostKeychecking=no -o NumberOfPasswordPrompts

I'm fairly new in using Ansible and have been reading here and google and haven't found an answer yet. My scenario is that I have 1 user on a server but 2-3 different pub keys that need to put in it's authorized_keys file. I can successfully remove all keys, or add all keys with this script: --- - hosts: all tasks: - name: update SSH keys authorized_key: user: <user> key: "{{ lookup('file', item) }}" state: present #exclusive: yes with_fileglob: - ../files/pub_keys/*.pub With the present flag it reads and adds all the keys. With the absent flag it removes all keys listed. Problem is that I

I setup a Docker image that supports ssh. No problem, lots of examples. However, most examples show setting a password using passwd. I want to distribute my image. Having a fixed password, especially to root, seems like a gaping security hole. Better, to me, is to setup the image with root having no password. When a user gets the image they would then copy their public ssh file to the image /root/.ssh/authorized_keys file. Is there a recommended way to do this? Provide a Dockerfile that builds on my image with an ADD command that user can edit? Provide a shell script that runs something like

I've created an RSA public key and I want to add that to authorized_keys file, but there is no such file in my Ubuntu 11.10 machine. How can I add the key to authorized_keys ? donden1 Make sure when executing Michael Krelin's solution you do the following cat <your_public_key_file> >> ~/.ssh/authorized_keys Note the double > without the double > the existing contents of authorized_keys will be over-written (nuked!) and that may not be desirable Michael Krelin - hacker mkdir -p ~/.ssh/ To overwrite authorized_keys cat <your_key >~/.ssh/authorized_keys To append to the end of authorized_keys cat
