scp copy files from windows to linux

[jing hu]

windows is source machine.
I need copy files from windows to linux.
In windows I set up cygwin and ssh , and run" ssh-keygen -t rsa" to id_rsa.pub and id_rsa.
Then copy the file id_rsa.pub to linux ~/.ssh directory.(here I use wincp)
in the linux ~/.ssh directory I create authorized_keys file and type the command " cat id_rsa.pub >> authorized_keys"

Then in the linux machine, I run

scp user@windowsmachine:/home/user/test.txt .

it return the error :ssh: connect to host 9.123.*.*port 22: Connection refused

Can anybody tell me the answer or solution.
Thanks very much.

If you want to run scp on the Linux box, then the ssh daemon (sshd) has to be running on the Windows box. It can be set up to run as a Windows service, which is a little messy but doable.

Thanks, Ernest. your suggestion is very valuable. I have resolved my question according to your tip.
it just only need ssh-host-config and some chmod operations.
Thanks very much
