SSH/SFTP login with public/private keys between a linux machine (server) and a windows (client)
This is a small guide, for mostly personal use, that's why it is not very detailed.
Anyway, the content is derived from the two references below:
(1)
http://www.howtoforge.com/ssh_key_based_logins_putty
(2)
http://sshkeychain.sourceforge.net/
- Generate keys with PuttyGen
2048 bit, SSH-2 RSA
add a key comment like
name@machine
add a passphrase (this is optional and I haven't done it)
- Save the keys in a safe place
NOTE: You can also export the private key in other format (SSH, openSSH)
- Copy the public key on the server you want to login into
in the file
~/.ssh/authorized_key2
- MODIFY the access of ~/.ssh to be readable/writeable/executable ONLY by that user:
"
chmod 0700 ~/.ssh"
- MODIFY the access of
~/.ssh/autorized_key2 to be readable/writeable ONLY by that user:
"
chmod 0600 ~/.ssh/authorized_keys2"
- Disable the login with password by modifying (e.g. with vi) the file "
/etc/ssh/sshd_config" as it follows:
Protocol 2
PasswordAuthentication no
UsePAM no
NOTE: in
/etc/ssh there is
ssh_config and
sshd_config choose the right one!
- Restart the SSH server
/etc/init.d/sshd restart
That's it.
