I've had the idea to set-up a personal server to easily manage my documents and other minor projects. As I'm fairly new to SSH, I was wondering how to manage keys with multiple devices. Disabling password authentication in favor of public key (RSA) makes it seemingly impossible to add new keys to my server. Currently, my sshd_config file has these functions set:
Code:
RSAAuthentication yes
PubkeyAuthentication yes
PasswordAuthentication no
On one device, I set PasswordAuthentication to "yes," added its public key, and I can connect fine. On another, I cannot send my public key at all: "Permission Denied (publickey)". I realize that the simplest solution, mentioned in a couple forum posts, would be enabling password authentication; but, I am under the impression that RSA is more secure, so I'd prefer using it.
So, I guess my question is twofold:
a) how can I easily use keys between multiple devices without turning PasswordAuthentication on, or
b) would using my Linux user password over SSH be less-secure than using RSA?
