Has anyone else experienced this. I have three or so local boxes, all of them has my host machines key in `authorized_hosts, but only one starts a session without asking for a password. I don't know much about the ssh config, what could cause something like this? Each box is configured identically from an almost identical Vagrantfile. The only difference is a change of the IP.
You’re using “vagrant ssh,” right? What platform are you using to host your VMs?
if you are just running the ssh command line to access them, pass the ‘-v’ flag to see whats happening with the authentication
ssh -vv some_host
ssh is very sensitive to the ownership and permissions to the .ssh directory and its contents, check these very carefully
