I've been reading the thread about detecting hack attempts and I am
interested in in setting up "key based authentication" as described
[perhaps] in
"https://docs.fedoraproject.org/en-US/Fedora/14/html/Deployment_Guide/s2-ssh-configuration-keypairs.html"
In doing this is their danger of making an error and locking myself out
of my computer, if so what to avoid? I've made some catastrophic errors
in the not very distant past that required a new system re-installation
and would prefer not repeating that.
Suggestions, thoughts?
Besides the other suggestions, for the more "mechanical" part of the process I highly recommend ssh-copy-id.
It will check that you have correct permissions in ~/.ssh before copying the public key over to the remote system. If course you'll need to leave password auth turned on until you complete this.
Thanks,
