I'm facing problem when I pull a file from another machine to my machine using SCP. File is successfully transferred but each time it asks for password. I want to run this SCP command as a cronjob, How can I save password for this automation?
scp [email protected]:/usr/etc/Output/*.txt /usr/abc/
[email protected]'s password:
You can do:
(if not already done) generate a set of public and private ssh keys on your machine for your user with:
$ ssh-keygen
Answer the questions in order to generate the set of keys.
copy your public key to the remote host:
$ ssh-copy-id remote-user@remote-host
This will enable login-in from your username@host to remote-user@remote-host without being prompt with p/w authentication.
ssh-copy-id will take care of copying the encrypted credentials onto the remote host, that way it won't prompt for p/w next time that user ssh onto it.
you can use this:
sshpass -p 'your_password' scp [email protected]:/usr/etc/Output/*.txt /usr/abc/
but remember that you store password in plaintext.
My version of ssh-copy-id requires '-i' option to work, or else it will assume copying credentials from ssh-agent, which will not work if you are not using it.
ssh-copy-id -i $myfile.pub remote-user@remote-host
