I'm trying to setup passwordless login for from my mac to my remote server running CentOS with public key authentication for "user1".
I used $ ssh-keygen -t rsa
to setup a public key on my mac and then copied the mykey.pub file over to the CentOS user1's .ssh dir and then did a
cat mykey.pub >> authorized_keys
in the .ssh dir.
I've also set the permissions for the .ssh dir to 700 and the authorized_keys to 600.
when I do a:
ssh user1@myremoteserver.com
It still prompts me for my password.
What's going on?
Here is a copy of my sshd_config file on the remote machine:
Protocol 2
SyslogFacility AUTHPRIV
PermitRootLogin no
RSAAuthentication yes
PubkeyAuthentication yes
AuthorizedKeysFile .ssh/authorized_keys
PasswordAuthentication yes
PermitEmptyPasswords no
ChallengeResponseAuthentication no
GSSAPIAuthentication yes
GSSAPICleanupCredentials yes
UsePAM no
AcceptEnv LANG LC_CTYPE LC_NUMERIC LC_TIME LC_COLLATE LC_MONETARY LC_MESSAGES
AcceptEnv LC_PAPER LC_NAME LC_ADDRESS LC_TELEPHONE LC_MEASUREMENT
AcceptEnv LC_IDENTIFICATION LC_ALL
X11Forwarding yes
Subsystem sftp /usr/libexec/openssh/sftp-server
More info:
Here is my output for ssh -v. I think the system defaulted to using the id_rsa.pub instead of the mykey.pub and the mykey (private key file) that I named.

How does one tell the system to use mykey instead of the id_rsa?
