use ssh scp without password - AthenaTzeng/myTool GitHub Wiki
[email protected] want to use ssh/scp to [email protected]
IDEA: make a pub/priv key for from and write the pub_key to to
from$ ssh-keygen -t rsa
Enter file in which to save the key (/home/from/.ssh/id_rsa):[Enter]
Enter passphrase (empty for no passphrase):[Enter]
Enter same passphrase again:[Enter]
from$ scp /.ssh/id_rsa.pub [email protected]:/
[Enter password]
to$ cat id_rsa.pub >> .ssh/authorized_keys2
==>NOTE: this is because of that the authorized_keys2 might exist
if so, just add the chars in id_rsa.pub at the end of the file
-
NOTE for dsa
from$ ssh-keygen -t dsa
to$ cat id_dsa.pub >> .ssh/authorized_keys -
NOTE!!!
from and to must be the correct users
only this two users can have the no-password ssh link (scp)
