How to scp from Windows 7 with private key without password?

Question

I have a public and private key in X:\secure. Straight ssh with the private key works and I connect okay:

ssh -i X:\secure\id_rsa remoteuser@remote.server.com

The remote server is all set up for ssh and has the public key from X:\secure\id_rsa.pub added to /etc/ssh/authorized_keys/remoteuser.

However, when I try to send a file over using

scp somefile.txt -i X:\secure\id_rsa remoteuser@remote.server.com:~

I get prompted for password.

Question: Is there a way to scp a file over seamlessly, without a prompt, just like ssh connection is established using a private key?

Answer 1

I'm on a Winows 10 machine, connecting to a Ubuntu server. I've set it up so that I can only connect with a private key with a passphrase.

I'm using cmder and this works in Windows:

scp -i ~\.ssh\privatekey foobar.txt linuxuser@server:/home/linuxuser

~.ssh\ referes to C:\Users\.ssh\

Answer 2

i am on linux so i can not test this but have you tried:

scp -i X:\secure\id_rsa somefile.txt remoteuser@remote.server.com:~

i'm pretty sure you have to put the options before the source file. if you're getting a password prompt then the key is not being sent.
