Automatic SSH/SCP Login without Password
- generate on your LOCAL machine a keypair with: ssh-keygen -t rsa (dont type in any password, just keep hitting enter)
- make sure your private key resides under ~/.ssh (under windows this can be under c:\documents and settings\yourname\.ssh or under c:\cygwin\home\yourname depending on your ssh-keygen tool which you need to download
- file transfer the PUBLIC key to the machine you which to automatically logon to. Under the directory ~/.ssh (create it if necessary) concatenate your public key with the file authorized_keys (create file if needed)
- make sure the authorized_keys is not read or modifiable by group or others my doing chmod 700 ~/.ssh/authorized_keys
- make sure the ~/.ssh directory on the REMOTE machine is not read or modifiable by group or others my doing chmod 700 ~/.ssh
- You may need to enable empty password authentication (need root access) on the REMOTE machine in the config file sshd_config. Make "permitemptypasswords yes". Restart SSH Daemon on REMOTE.
- On some machines, you may also need to make sure your HOME directory is not writable by group or world. Type chmod 700 ~
