 The problem lies in ftp(1).

 Logic in the ports tree is fine. But there's nothing it can do there:
 your ftp returns 0 (e.g., success), so the partial file gets removed.

 If you want to get it fixed, you may have to provide more input, as we
 obviously do not see that problem... First thing would be to override
 FETCH_CMD to remove the -V, so that you can show us what ftp says about
 things.  Tracing the code thru the program would help.

 It's a good thing that traffic analysis isn't a thing, then. Otherwise

That's not the scenario here. The scenario is defense against port scans.

 Well, if, as Herr Schroeder seems to be implying, this is used to
 avoid port scans, I'd look for traffic to/from address:port which
 don't show up on scans.

That's certainly possible but more expensive than find all ssh servers.

 I still don't see the benefit though but do see added complexity or
 more code to audit.

 Reducing DDOS against a visible SSH service maybe? Reduce password
 attempts on your logs allowing them to go after targets that might
 actually use passwords (port change also works there, I find)?

 Just a short heads up how I did it now and you guys might want to share your
 opinion on the security with this scenario.

 maschine A (from were I want to pull files):
 - root cant login over ssh
 - sync user can only connect with auth key and from host B
 - sync user is allowed to run rsync without pw (sudoer file)

The setup I use
- a separate non-privileged user
- a forced command (via the ssh key without password) to a script that
  checks the incoming command and then calls sudo rsync

So someone controlling machine B can _read_ everything, but write


#!/usr/bin/env bash
# $Id:,v 1.3 2007/07/01 12:40:14 remote-backup Exp $
  *rsync --server --sender*)
logger -t rrsync $SSH_ORIGINAL_COMMAND
echo Sorry, command rejected

2014-06-20 Thread Martin Schröder
quote src=;
Earlier this year, before Apple had too many goto fails and GnuTLS had
too few, before everyone learnt that TLS heart-beat messages were a
thing and that some bugs are really old, I started a tidy up of the
OpenSSL code that we use at Google.

We have used a number of patches on top of OpenSSL for many years.
Some of them have been accepted into the main OpenSSL repository, but
many of them don’t mesh with OpenSSL’s guarantee of API and ABI
stability and many of them are a little too experimental.

But as Android, Chrome and other products have started to need some
subset of these patches, things have grown very complex. The effort
involved in keeping all these patches (and there are more than 70 at
the moment) straight across multiple code bases is getting to be too

So we’re switching models to one where we import changes from OpenSSL
rather than rebasing on top of them. The result of that will start to
appear in the Chromium repository soon and, over time, we hope to use
it in Android and internally too.

There are no guarantees of API or ABI stability with this code: we are
not aiming to replace OpenSSL as an open-source project. We will still
be sending them bug fixes when we find them and we will be importing
changes from upstream. Also, we will still be funding the Core
Infrastructure Initiative and the OpenBSD Foundation.

But we’ll also be more able to import changes from LibreSSL and they
are welcome to take changes from us. We have already relicensed some
of our prior contributions to OpenSSL under an ISC license at their
request and completely new code that we write will also be so
