- From the tahoe-dev Mailing List
===============================

As promised, this is the issue where we catch up on the mailing list posts
from our outage.  Next week will resume our regularly scheduled TWN.

Tahoe-LAFS and Ports
- --------------------

Marko Niinimaki posted a question regarding `what TCP ports Tahoe-LAFS
uses`_.  From docs/configuration.rst:

"``tub.port = (integer, optional)``

    This controls which port the node uses to accept Foolscap connections
    from other nodes. If not provided, the node will ask the kernel for any
    available port. The port will be written to a separate file (named
    ``client.port`` or ``introducer.port``), so that subsequent runs will
    re-use the same port."

Hopefully this answers Marko's question.  I will be adding the question and
its answer to the `FAQ`_.

Volunteer Grid 2 Hits a Milestone
- ---------------------------------

Shawn Willden `announced VG2 hitting a major milestone`_.

  "VG2 hit a milestone sometime early this morning or late last night:  20
  nodes!  20 highly-available (95+% uptime), high capacity (500 GB - 1 TB)
  nodes, distributed all over the world.  Well, we'll see if the newest nodes
  meet the availability standard, but their operators have committed to it.

  According to the stats gatherer (which appears to have data on 16 of the
  nodes -- we'll get the others in there), we currently have just over 9 TB
  available storage space, right around 6 TB used, and we're uploading 140 GB
  per day.

  Next goal:  32 nodes highly-reliable nodes." [`0`_]

Congratulations to all the members of VG2 and good luck hitting your next
milestone.

Welcome Page
- ------------

Ted Rolle, Jr `requested a couple fixes to the welcome page`.  The first
request was to order the nodes by nickname rather than by peer ID.  This is
ticket `#1709`_.  The second requested was to change 'To' to 'to'.  This is
ticket `#1708`_ and has already been fixed.

New Web UI Concept
- ------------------

Tony Arcieri `began work on a new Web UI` using the Twitter Bootstrap CSS
Framework.  His work is built with a responsive layout which will allow to it
degrade to the appropriate screen size.  This would allow the web UI to fit
comfortably in the screen of your smart phone.  The response to the work has
been favorable and a ticket exists at `#1713`_ if you would  like to review
it or learn more.

AppArmor Profile
- ----------------

Mike Kazantsev `created an AppArmor profile` for Tahoe-LAFS.  `AppArmor` is

  "an effective and easy-to-use Linux application security system. AppArmor
  proactively protects the operating system and applications from external
  or internal threats, even zero-day attacks, by enforcing good behavior and
  preventing even unknown application flaws from being exploited.  AppArmor
  security policies completely define what system resources individual
  applications can access, and with what privileges. A number of default
  policies are included with AppArmor, and using a combination of advanced
  static analysis and learning-based tools, AppArmor policies for even very
  complex applications can be deployed successfully in a matter of hours."

Further information can be found on the `Tahoe-LAFS AppArmor`_ page.  I would
really like to see this profile incorporated into Debian and Ubuntu packages
of Tahoe-LAFS.
