James H (5 July 2007)

- Gavrie Philipson provided a patch that will use a more specific error

  message for an scp:// upload failure.  If libssh2 has his matching

  patch, then the error message return by the server will be used instead

  of a more generic error.

Daniel S (1 July 2007)

- Thomas J. Moore provided a patch that introduces Kerberos5 support in

  libcurl. This also makes the options change name to --krb (from --krb4) and

      if (!scp->ssh_channel &&

          (libssh2_session_last_errno(scp->ssh_session) !=

           LIBSSH2_ERROR_EAGAIN)) {

        return CURLE_FAILED_INIT;

        int err;

        char *err_msg;

        err = libssh2_session_error_to_CURLE(

            libssh2_session_last_error(scp->ssh_session, &err_msg, NULL, 0));

        failf(conn->data, "%s", err_msg);

        return err;

      }

    } while (!scp->ssh_channel);
