I have a pair of private and public keys. The public key is on my server and I have my private key on my local disk. The file's permissions were changed with the command:
chmod 600 private_key
Now I try to login into my server with the command:
ssh -i path_to_the_private_key username@servername
My Mac shows me a dialog box and asks me for the password. I enter the password but my Mac says the password is incorrect.
When I use the same private key to log to the same server with the use of putty and the same password everything works great.
Any hints?
