Managing SSH keys

[desperados]

Hi all
I have many servers and many users that need to access them
I use ssh keys, generate one for each user and enable them adding their public key in authorized_keys
but it's a messy, a lot of keys and I don't know the exact configuration of every host, and I need to connect to check, revoke, add, etc

is there a tool to manage servers and users in a easy and fast way?
thanks

We use ansible for that kind of thing where I work. Ansible runs on one controller machine, connects to other machines (listed in an inventory file) with ssh and then runs scripted configuration tasks. It's easily capable of what you want to do, maybe overkill, but worth a look. https://docs.ansible.com/ansible/latest ... intro.html

for many servers and many users you need something like idm. For example RedHat IDM. link below https://access.redhat.com/documentation ... troduction

You can create host access rules for users and map sudo rules.

Also you can read about freeipa https://www.freeipa.org/page/Main_Page
