Hi,

The internal ssh client can not understand ssh1 public/private key.

So, generate key pair by "ssh-keygen -t rsa" or "ssh-keygen -t dsa" and
you will have key-pair like "id_dsa, id_dsa.pub" or "id_rsa,id_rsa.pub".
And, you have to set its private key explicitly with setKeyfile method.

              scpConnection.setKeyfile("/home/nettrade/.ssh/id_dsa");

then, you must set something as a passphrase even if it is not
encrypted, because
there is a bug.

              scpConnection.setPassphrase("");

Dear developers, to resolve above bug, following lines in=20
org/apache/tools/ant/taskdefs/optional/ssh/Scp.java

        if (getUserInfo().getPassword() =3D=3D null
            && getUserInfo().getPassphrase() =3D=3D null) {
            throw new BuildException("neither password nor passphrase for u=
ser"
                                     + getUserInfo().getName() + " has been=
 "
                                     + "given.  Can't authenticate.");
        }

should be

        if (getUserInfo().getPassword() =3D=3D null
            && (getUserInfo().getPassphrase() =3D=3D null &&
getUserInfo().getKeyfile()=3D=3Dnull)) {
            throw new BuildException("neither password nor passphrase for u=
ser"
                                     + getUserInfo().getName() + " has been=
 "
                                     + "given.  Can't authenticate.");
        }
