This week's issue begins with announcements from the Project, including notice of scheduled downtime on 03-16-2011 of the Serverbeach servers, details on the Gnome 3 Test Day, and pointers to Fedora Events happening through May. In the News this week brings two Fedora 15 Alpha reviews, one focused on Gnome 3 shell and one German language general feature review. In Quality Assurance, details on the latest Test Days for Fedora, including next week's preupgrade Test Day, as well as a look at Fedora 15 beta preparations. Security Advisories brings us current with Fedora 13, 14 and 15 security packages released over the past week, and our issue reaches its finale with another Spanish language contribution in Fedora LATAM, this week on Ruby Ping from Guillermo Gómez! Enjoy!

Reminder: today is GNOME 3 Test Day #2

Adam Williamson announced[1],

"Hi, everyone! Just a quick reminder that today is the second Test Day for GNOME 3:[2] . Please do come along and help with testing if you can. We're having trouble with the 32-bit live image, but a 64-bit image is available now and all the test instructions are in place. We'll be in #fedora-test-day on IRC all day long to help out with testing, so come along and join us there.

Fedora Events

The purpose of event is to build a global Fedora events calendar, and to identify responsible Ambassadors for each event. The event page is laid out by quarter and by region. Please maintain the layout, as it is crucial for budget planning. Events can be added to this page whether or not they have an Ambassador owner. Events without an owner are not eligible for funding, but being listed allows any Ambassador to take ownership of the event and make it eligible for funding. In plain words, Fedora events are the exclusive and source of marketing, learning and meeting all the fellow community people around you. So, please mark your agenda with the following events to consider attending or volunteering near you!

Upcoming Events (Dec 2010 - Feb 2011)

  • North America (NA)[1]
  • Central & South America (LATAM): [2]
  • Europe, Middle East, and Africa (EMEA)[3]
  • India, Asia, Australia (India/APJ)[4]

First Look at Fedora 15 Alpha With Gnome Shell (thisweekinlinux.com)

Rahul Sundaram forwarded[1] an initial look at Fedora 15 Alpha's Gnome 3 Shell experience:

"After using this for a day or two at work, watching some of the upgrades that have happened, and showing it to coworkers, I have to say, I’m very pleased so far! Gnome 3 / Gnome Shell is really shaping up to be very useful, and the performance has significantly improved from the last time I used it."

Fedora 15 Alpha vorgestellt (Pro-Linux.de)

Henrik Heigl forwarded[1] an article from the German Pro-Linux.de blog on Fedora 15 Alpha:

"Fedora 15 "Lovelock" Alpha ist eine Vorschau auf die offizielle Version, die bereits alle geplanten Features von Fedora 15 enthält, aber noch nicht notwendigerweise in der endgültigen Form, und nur zum Testen eingesetzt werden sollte. Nach der Korrektur der meisten Fehler der Alphaversion soll am 12. April eine Betaversion veröffentlicht werden, die vom Code her vollständig sein soll.

Die Alphaversion kommt mit einer Vorschau auf GNOME 3 sowie den neuesten Versionen von KDE und Xfce. Das neue Init-System systemd wird standardmäßig eingesetzt. Systemd dient auch zur Sitzungsverwaltung. LibreOffice ersetzt OpenOffice.org. Für Unternehmen wurde das Buchhaltungs- und Inventarsystem Tryton hinzugenommen. Das neue Werkzeug BoxGrinder soll es leicht machen, virtuelle Maschinen für Plattformen wie KVM, Xen und Amazon EC2 aus einfachen Definitionsdateien zu erzeugen."

Test Days

Thursday 2011-03-10 was the second of three planned GNOME 3 Test Days[1]. Despite a reduced turnout, a lot of valuable testing took place thanks to the dedication of those who did show up, and many more bugs were discovered - some being fixed during the event. Vitezslav Humpa, who along with Radek Lat helped to organize this event, posted a recap [2] to the mailing list with a good overview of all the reported bugs.

Thus Thursday, 2011-03-17, will be preupgrade Test Day[3], where we will be testing this important mechanism for upgrading to Fedora 15. Upgrading is always one of the thorniest areas of a Fedora release, so if it's important to you and you can come along and help test, please do - the more testing we can get early on, the better the final result will be.

Next Thursday, 2011-03-24, is scheduled as power management Test Day[4], to test out various aspects of power management in Fedora 15. However, planning for the event is not yet complete, so it may be cancelled or postponed.

Test case management system comparison

Continuing her ongoing work on test case management system evaluation, Rui He posted a proposed list of features[1] that the candidate new system, Nitrate, must have before it can replace the current system of using the Wiki to organize test cases. After James Laska replied[2], the two continued to discuss and refine the list.

Fedora 15 Beta preparation

The first Beta blocker/nice-to-have review meeting took place on 2011-03-11[1], and the team worked through the full list of proposed Beta blocker and nice-to-have bugs. The first Beta test compose is due for release on 2011-03-22.

LATAM Fedora!

LATAM Fedora is a regular column of Spanish language contributions around open source software. It is our first expansion into incorporating foreign language content into FWN.

This week's contribution is from Guillermo Gómez, a primer on Ruby Ping. Enjoy!

Ruby Ping

En paralelo con el tutorial de Ruby, que pronto verá su segundo capítulo, vamos en paralelo para publicaciones más frecuentes como FWN a escribir acerca del uso del lenguaje en otras tareas específicas, hoy nos ocupa algunas formas de hacer "ping" con Ruby.

Ping: librería estandar

Ping.pingecho utiliza TCP echo no ICMP echo para determinar si un máquina remota esta "viva". En realidad puede utilizar "otros" puertos, no necesariamente echo tcp/7.

1 irb(main):013:0> require 'ping' 2 => true 3 irb(main):012:0> Ping.pingecho('gomix.fedora-ve.org', 10) 4 => true 5 irb(main):016:0> Ping.pingecho('gomix.fedora-ve.org', 10, 'http' ) 6 => true

NOTA: si existe un paquete de rechazo ICMP al puerto especificado, se considera que la máquina está viva, es decir, "respondió con ICMP", así que no asuma que el puerto está abierto por el hecho de que Ping.pingecho le devuelva true.

net-ping

  1. gem install net-ping

Fase común genérica para los siguientes ejemplos.

1 irb(main):001:0> require 'rubygems'
2 => true
3 irb(main):005:0> require 'net/ping'
4 => true

Ping UDP y TCP.

1 irb(main):011:0> host = "gomix.fedora-ve.org" 
2 => "gomix.fedora-ve.org" 
3 irb(main):012:0> u = Net::Ping::TCP.new(host)
4 => #<Net::Ping::TCP:0x7fb1cf3e16f0 @duration=nil, @timeout=5, @warning=nil, @exception=nil, @host="gomix.fedora-ve.org", @port=7>
5 irb(main):013:0> u.port = 80
6 => 80
7 irb(main):014:0> p u.ping?
8 true
9 => nil
10 >>  u = Net::Ping::UDP.new(host)
11 => #<Net::Ping::UDP:0xb74b6a38 @duration=nil, @warning=nil, @data="ping", @timeout=5, @exception=nil, @bind_port=nil, @host="www.ruby-lang.org", @port=7, @bind_host=nil>
12 >> p u.ping?
13 false

NOTA: en este caso el rechazo tanto a nivel TCP como ICMP no es indicativo de que la "máquina" esté viva, es decir, aquí el PING es específico al servicio/puerto que se está probando, no a la máquina. Note en el último caso el ping-tcp al puerto 80 donde si hay respuesta porque hay un servidor web funcionando allí.

Ping ICMP con net-ping.

1 irb(main):011:0> host = "gomix.fedora-ve.org" 
2 => "gomix.fedora-ve.org" 
3 irb(main):015:0> u = Net::Ping::ICMP.new(host)
4 => #<Net::Ping::ICMP:0x7fb1d1358088 @pid=8696, @data="\000\001\002\003\004\005\006\a\b\t\n\v\f\r\016\017\020\021\022\023\024\025\026\027\030\031\032\e\034\035\036\037 !\"\#$%&'()*+,-./012345678", @duration=nil, @data_size=56, @timeout=5, @bind_port=0, @warning=nil, @exception=nil, @seq=0, @host="gomix.fedora-ve.org", @bind_host=nil, @port=nil>
5 irb(main):016:0> p u.ping?
6 true
7 => nil

Tenga presente que:

1 >> u = Net::Ping:ICMP.new(host)
2 RuntimeError: requires root privileges
3     from /usr/lib/ruby/gems/1.8/gems/net-ping-1.4.0/lib/net/ping/icmp.rb:25:in `initialize'
4     from (irb):5:in `new'
5     from (irb):5
6 

Ping "external", esta opción utiliza la utilidad "ping" de su sistema operativo.

1 >> host="200.44.32.12" 
2 => "200.44.32.12" 
3 >> u = Net::Ping::External.new(host)
4 => #<Net::Ping::External:0xb73fbd50 @duration=nil, @warning=nil, @timeout=5, @exception=nil, @host="200.44.32.12", @port=7>
5 >> p u.ping?
6 true

Por cierto, net-ping no está empaquetado en Fedora, ello es una buena oportunidad para que comiences tu primer proyecto de empaquetamiento de rubygems en Fedora, contáctame y suscribe en el grupo de desarrollo latinoamericano RPMDev .
