But when I try to scp a file from my client to the server "scp test.txt remoteuser@10.7.4.2, it always ask for a password. There is no password since my ssh is public keyed, and so is my vpn connection.
first i would like to say that this has nothing to do with openvpn...
are you running a ssh-agent on your client? (f.e pageant)
