Gentoo store: 2006.0 release media available
--------------------------------------------
  
Official 2006.0 CD releases[1] have hit the Gentoo store this week! Five 
USD from every CD sale goes to the Gentoo Foundation[2], presenting a 
clever way to financially support the development of Gentoo Linux through 
purchasing the release media directly from the project.

Gentoo community directory
--------------------------
  
It's increasingly difficult to keep track of the multitude of 
international activities in and around the Gentoo project. Developers, 
power users and enthusiasts around the globe organize Gentoo-related 
events, hold classes at their universities, and man Gentoo booths at trade 
fairs and conferences. To keep up with what's going on internationally, 
the GWN team is actively looking for Gentoo user groups, associations, 
clubs or study circles that represent users or developers in their own 
town or country. If you're running a Gentoo-related website, a forum, a 
monthly user meeting or other events, please submit a short description of 
your activities and your contact details to our feedback address[3] so we 
can start setting up a Gentoo community directory. Thanks a lot in 
advance!

glibc 2.4
 
glibc 2.4 officially hit the Portage tree. Forum users were surprised to 
see that it got straight into ~arch instead of being hard masked first. 
However, they did quite a lot of tests, like rebuilding the toolchain and 
all seemed to go well. Some of them even tried it with GCC 4.1 and 
experienced no problems. Nevertheless, they did find some minor issues 
when building nptl-only applications:

Forum veteran taskara[5] just released a custom Gentoo LiveCD that 
provides Xgl support. Users who tried it are rather pleased with that kind 
of 3D hardware support on a LiveCD. Links and torrents are inside the 
thread, and of course you can discuss it right there:

Gentoo developer Shyam Mani[7] will give an introductory talk about Gentoo 
during the FOSS.NITC[8] event at the National Institute of Technology in 
Calicut (Kerela) on 18 and 19 March. Together with fellow Gentoo 
enthusiast Ashish V, he plans to hold a Gentoo BoF (Birds of a Feather) 
session as well sometime during the event. Check the event schedule[9] for

On Friday, 17 March 2006, a group of Gentooists from the Leipzig and Halle 
area in Saxony will meet for an evening at the Stuk[10] (Studentenkeller). 
This first Leipzig GUM will start at 19:00, and if you're interested in

Germany: Report from Chemnitz
-----------------------------
  
As in 2005, the Linuxtage in Chemnitz (4 and 5 March 2006) were not only 
visited by Gentoo developers, but you could also visit them at their booth 
for a little chat. You could see an SGI Octane constantly compile stuff, 
but at the end of the second day, finally xorg was running. Of course 
devotional objects such as stickers or a DVD with the 2006.0 release plus 
some extra goodies like stage archives and a lot of source packages could 
be purchased at the stand. Tobias Scherbaum[12] also gave a speech about 
Gentoo.

Linux Magazin (4/2006, in German)
---------------------------------
  
The April edition of Germany's Linux Magazin dedicates its cover story and 
half a dozen in-depth articles inside the printed magazine to 
virtualization in all its forms. One article features Gentoo developer 
Benedikt Böhm[13] and the vserver project for Linux, based on the 
vserver-sources and utilities provided in Gentoo. The magazine is 
available at news stands in German-speaking countries.

Last week we published a reference to an interview with Bill Hilf, 
Microsoft's open-source lab director. Now the full publication is 
available, the 2006 edition of the Open-Source Jahrbuch[14] can be

5. Tips and tricks
==================
  
Iproute2 instead of ifconfig/route
----------------------------------
  
For many, ifconfig and route are still the preferred commands for 
configuring a network through the command line. However, in modern network 
environments, ifconfig has its drawbacks. And as you would expect from a 
Free Software community, improved packages have been developed. iproute2 
is one of them and is getting increasingly popular. 
 
The default command to work with iproute2 is ip. Clean, simple to remember 
and extremely powerful. But its power is well described in many documents, 
including the iproute2 document[15] and the Guide to IP Layer Network 
Administration with Linux[16]. In this short introduction, we'll stay with 
the simplest basics that most people use just to show you how easy it is 
to "migrate" from ifconfig (sys-apps/net-tools) to ip (sys-apps/iproute2). 

 15. http://www.policyrouting.org/iproute2.doc.html
 16. http://linux-ip.net/html/
 
To configure a host to use IP address 192.168.0.102, netmask 255.255.255.0 
and default gateway 192.168.0.1, the "old" commands were: 
 
+-------------------------------------------------------------------------+
| Code Listing 5.1:                                                       |
| Using ifconfig and route                                                |
+-------------------------------------------------------------------------+
|                                                                         |
|# ifconfig eth0 192.168.0.102 netmask 255.255.255.0 up                   |
|# route add default gw 192.168.0.1                                       |
|                                                                         |
+-------------------------------------------------------------------------+
 
Using iproute2, this becomes: 
 
+-------------------------------------------------------------------------+
| Code Listing 5.2:                                                       |
| Using iproute2's ip command                                             |
+-------------------------------------------------------------------------+
|                                                                         |
|# ip address 192.168.0.102/24 dev eth0                                   |
|# ip route add default via 192.168.0.1                                   |
|                                                                         |
+-------------------------------------------------------------------------+
 
The syntax isn't all that difficult, is it? Let's take a look at our 
current routing table. With route you would run route -n: 
 
+-------------------------------------------------------------------------+
| Code Listing 5.3:                                                       |
| Using route                                                             |
+-------------------------------------------------------------------------+
|                                                                         |
|# route -n                                                               |

+-------------------------------------------------------------------------+
 
With ip, you ask it to show the routes: 
 
+-------------------------------------------------------------------------+
| Code Listing 5.4:                                                       |
| Using ip to show the routing table                                      |
+-------------------------------------------------------------------------+
|                                                                         |
|# ip route show                                                          |
|192.168.0.0/24 dev eth0  proto kernel  scope link  src 192.168.0.121     |
|127.0.0.0/8 via 127.0.0.1 dev lo  scope link                             |
|default via 192.168.0.1 dev eth0                                         |
|                                                                         |
+-------------------------------------------------------------------------+
 
You might find this output strange; however, it gives a lot of useful 
information. For instance, scope link means that the network is reachable 
while proto kernel informs us that the kernel has added this routing as 
part of bringing the interface up. 
 
Using ip within Gentoo isn't difficult either. The Gentoo 
sys-apps/baselayout package supports both formats (ifconfig and ip):
