Cherokee 0.6.0 relased

The cherokee team just relased version 0.6.0, as higlights:

• Web based admin interface (cherokee-admin, USE=admin)
• 20% 25% faster
• Load balancing
• Recover mechanism
• More authentication modules
• New documentation system
• Theme support

The new ebuild is already in portage including cherokee-admin and cherokee-guardian. The configuration is totally different so you need to create a new one using cherokee-admin or use /usr/share/doc/cherokee-0.6.0/contrib/05to06.py to export your old config (doesn’t wokrs 100%).

Dell xps m1330 & Gentoo (back from FOSDEM)

Well is my first week with my new laptop (Alice) and i love it… This is only a list of tips/troubleshottings maybe usefull for other :

• you need a 2.6.24 kernel + net-wireless/iwl4965-ucode for complete out-box wifi support
  • my .config file: config 2.6.24-r2
• you need alsa-driver-1.0.16 (1.0.15 is in 2.6.24) to mic and sounds works corrrectly and define in /etc/modules.d/alsa :
  • options snd-hda-intel model=dell-3stack
• If you are using 2.6.24 you need to use >=x11-drivers/nvidia-drivers-169.09-r1 (~x86)
• If you want sleep/hibernate to work remember acpid & hald in the same runlevel
  • disble power button even handler in /etc/acpi/default.sh becuase it can conflict with hald
• Some usefull links:
  • xps on gentoo
  • triple boot howto
  • gentoo xps wiki

About FOSDEM was great again. I met old a lot of old friends, a few new ones ;) was great to see again Jonita adn Damian, and we enjoy like never in Delirium (the best bar), a lot of beer, girls and chocolat.

Going to FOSDEM

so see you there…

Cherokee + Gentoo + Trac micro HowTo

On today’s class we will configure our Cherokee web server to work with Trac :)

You need a system with trac, cherokee and apache-utils(htpasswd) installed (on Gentoo just emerge). We will use cherokee 0.5.6 (0.6.x is very stable so the config file is quite different). Remember to install Trac with FCGI support (on gentoo just USE=fcgi).

• First we need to modify a bit the trac fcgi interpreter to work on cherokee. We must to bind the fcgi port, in this case to 8000. Edit:

"/usr/lib/python2.4/site-packages/trac/web/fcgi_frontend.py" change "_fcgi.WSGIServer(dispatch_request).run()" to "_fcgi.WSGIServer(dispatch_request, bindAddress=("localhost", 8000)).run()"

• Now copy the trac cgi to a better location (the location depends on the trac version:

# cp /usr/share/webapps/trac/0.10.3.1/hostroot/cgi-bin/trac.fcgi /var/www/localhost/cgi-bin/

• And the final step, configure cherokee:

Directory /trac/$PROJ {
Handler fcgi {
ErrorHandler on
CheckFile off
Server localhost:8000 {
Env TRAC_ENV “/var/lib/trac/$PROJ”
Interpreter “/var/www/localhost/cgi-bin/trac.fcgi”
}
}
}

Directory /trac/$PROJ/login {
Auth Basic {
Name “Trac auth”
Method htpasswd {
PasswdFile /etc/cherokee/trac.htpasswd
}
}
}

Request "^/trac/[^/]+/chrome/common/(.*)$” {
Handler redir {
Show Rewrite “/trac/chrome/common/$1″
}
}

Request "^/trac/[^/]+/login/chrome/common/(.*)$” {
Handler redir {
Show Rewrite “/trac/chrome/common/$1″
}
}

Directory /trac/chrome/common {
Handler file
DocumentRoot /usr/share/trac/htdocs/
}

I will explain a bit each section:

1. We define our URL project, where to find it on our disk and where is the trac fcgi
2. Use this to have auth on trac. The file is create with htpasswd
3. 4 and 5 are nice redirectors to server static trac content without using the trac cgi

Remember to set perms on /var/lib/trac/$PROJ, to passwd and svn repos to user cherokee.

Now we have a fast and secure Trac system :)

Conky

I like conky :)

So you can use my config file if you like it.

GSoC updates

A blog to follow the GNAP CLI progress :)

The fastest squid redirector :)

ufdbGuard is now in portage (~x86). It is a really fast redirector for Squid. It can use proprietary blacklists or normal blacklists. ufdbguard is sponsored by  urlfilterdb. And of course it is GPL.

You can download the manual here.

It need some testing so enjoy!

GNAP in Google SoC (Road to GNAP^3)

Good news. GNAP have two students accepted in Google Summer of Code.

The idea is to create a Framwork for embedded systems using GNAP. Simple and easy as possible you will create a embedded system that fits your hardware. We have yet a lot of work, so if you can help you are welcome.

ToDo GNAP^3:

• Crossdev support (SoC)
• Cisco like CLI (SoC)
• Live upgrade firmware
• SquashFS packages (miniPMS)
• RedHat kernel 2.6.18 (it is sweet stable)
• UnionFS support
• Premade profiles for several archs

Our students are Stoile (Philipp) and Alster (Alexandros) and at moment three mentors: Jaervosz, Eroyf and Me.

If you want to help us just ask in #gentoo-gnap (freenode) or in gentoo-embedded MailList.

Congratulations to Philipp and Alexandros!

two useful scripts

• pgbench_suite.sh

- Use pgbench to benchmark a postgresql database
- “-m 1″ show sharedmem, “-m N” set sharedmem to N mb
- “-a” to help or just edit the first lines to configure it.

• sub2vid.sh

- Use mencoder/mplayer to add a subtitle file into a video file or to reencode it in other format.
- “-h” to help or edit the first lines to configure.

Enjoy :)
