Today
Ginger and I have received our
NBcool T1000 from
Specialtech.co.uk. We’ve never bought @Specialtech before but I’d like to recommend it because they were responsive to my emails, the package was well boxed and delivery times were as expected.
The product has two USB ports, one is used to power the embedded fan and the one left is for you to use it so no lost for you ;), it also has a switch so the fan can be turned on or off depending on your needs.
The 12cm fan is really quiet and big enough for our 12” laptops, the cooler is made from some sort of hard plastic but the at same time light to carry it around if you have enough room for it on your bag 
Let’s see next days about temperature, I’ve been reinstalling
Gentoo so I’m still emerging last applications.
As owner of three Windows Mobile devices (HTC Universal, Hermes and Kaiser) I needed a way to work with them under Linux so I decided to install
SynCE following
this wiki entry.
It was pretty straight ahead compilation, just encountered some minor problems which I could fix really easily. First we need to install subversion and gnet:
$ sudo equo install subversion gnet
Then create a build folder which will hold the sources of everything we need:
$ mkdir builds
$ cd builds
$ svn checkout http://synce.svn.sourceforge.net/svnroot/synce/trunk/libsynce
$ svn checkout http://synce.svn.sourceforge.net/svnroot/synce/trunk/librapi2
$ svn checkout http://synce.svn.sourceforge.net/svnroot/synce/trunk/odccm
$ svn checkout http://synce.svn.sourceforge.net/svnroot/synce/trunk/usb-rndis-lite
Now the compilation begins!
$ cd libsynce
$ ./autogen.sh
$ make && sudo make install
Now we’d have libsynce installed under /usr/local so let’s start with librapi2.
$ cd ../librapi2
$ ./autogen.sh
And the first problem shows up:
checking for LIBSYNCE... configure: error: Package requirements (libsynce >= 0.11.1) were not met:
No package 'libsynce' found
Fix:
$ export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
$ ./autogen.sh
$ make
And the second problem comes to scene:
/bin/sh ../libtool --tag=CC --mode=link gcc -I/usr/local/include -pthread -Wsign-compare -Wno-long-long -o pcp pcommon.o pcp.o ../src/librapi.la
gcc -I/usr/local/include -pthread -Wsign-compare -Wno-long-long -o .libs/pcp pcommon.o pcp.o ../src/.libs/librapi.so
pcommon.o: In function `adjust_remote_path':
pcommon.c:(.text+0xe0): undefined reference to `wstr_append'
pcommon.c:(.text+0xfa): undefined reference to `wstr_append'
pcommon.c:(.text+0x111): undefined reference to `wstr_free_string'
pcommon.c:(.text+0x131): undefined reference to `_synce_log_wstr'
pcommon.c:(.text+0x143): undefined reference to `wstrdup'
pcommon.o: In function `anyfile_remote_close':
....
Fix:
$ make LIBS=/usr/local/lib/libsynce.so
And here it comes again:
g++ -I/usr/local/include -Wall -pthread -g -O2 /usr/local/lib -o .libs/CeCreateDatabase CeCreateDatabase.o /usr/local/lib/libsynce.so ../../src/.libs/librapi.so
/usr/local/lib: file not recognized: Is a directory
collect2: ld returned 1 exit status
Fix:
$ cd tests/rapi
Edit the Makefile and look for a line like:
AM_LDFLAGS = /usr/local/lib
and comment it. I’m sure there’s a proper fix for this but it worked for me, so let’s try to build librapi2 again:
$ cd ../../
$ make LIBS=/usr/local/lib/libsynce.so && sudo make install
Now it should compile without a problem and install everything again under /usr/local. Let’s start with odccm:
$ cd ../odccm
$ make LIBS=/usr/local/lib/libsynce.so
And the same last problem shows up again:
gcc -Wall -I/usr/local/include -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -pthread -I/usr/include/gnet-2.0 -I/usr/lib/gnet-2.0/include/ -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/dbus-1.0 -I/usr/lib/dbus-1.0/include -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -DDBUS_API_SUBJECT_TO_CHANGE -I/usr/include/hal -I/usr/include/dbus-1.0 -I/usr/lib/dbus-1.0/include -g -O2 -o odccm odccm-device-signals-marshal.o odccm-device-manager-signals-marshal.o util.o odccm-errors.o odccm-connection-broker.o odccm-device.o odccm-device-manager.o odccm.o odccm-device-legacy.o /usr/local/lib -lgobject-2.0 -lglib-2.0 -pthread -lgnet-2.0 -lgthread-2.0 -lrt -lglib-2.0 -ldbus-glib-1 -ldbus-1 -lgobject-2.0 -lglib-2.0 -lhal -ldbus-1
/usr/local/lib: file not recognized: Is a directory
collect2: ld returned 1 exit status
Fix:
$ cd src
Edit the Makefile and look for the line odccm_LDADD = /usr/local/lib … and add -L after the equal.
odccm_LDADD = -L /usr/local/lib ...
So let’s compile:
$ make LIBS=/usr/local/lib/libsynce.so && sudo make install
So all userland is installed, let’s compile the kernel modules:
$ cd ../usb-rndis-lite
$ make && sudo make install
Keep in mind the kernel modules will have to be built every time the kernel is updated. So…let’s test! Plug your device in:
$ sudo /usr/local/sbin/odccm
$ dmesg | grep rndis
...
[86530.903513] rndis0: register 'rndis_host' at usb-0000:00:1d.1-1, RNDIS device (SynCE patched), 80:00:60:0f:e8:00
[86541.176471] rndis0: no IPv6 routers present
...

I was looking for an easy way to take away the Cisco VPN client for an open source solution,
vpnc. It’s a quite simple solution, which allows to convert Cisco profile files to its own configuration format and just works.
First take you .pcf file and convert it:
pcf2vpnc /path/to/file.pcf > /etc/vpnc/file.conf
The file.conf will look like the following:
## generated by pcf2vpnc
IPSec ID your_id
IPSec gateway xxx.xxx.xxx.xxx
IPSec secret the_secret
IKE Authmode psk
## To add your username and password,
## use the following lines:
Xauth username your_username
Xauth password your_password
Keep in mind my company is using a user:password pair, so if yours is issuing certificates the configuration for vpnc will be different from what I’m writing here.
Everything what’s left is to launch the vpnc with filename as argument:
vpnc file
And that’s all, if everything went well you should be connected to your work network!

After being testing
OpenSolaris in a virtual machine I decided to install it on my laptop. I have to admit it’s really easy to install even getting the wifi card working was a piece of cake…30s work!
The system seems fast, stable and usable…but for my laptop I found a couple of problems:
- SpeedStep is not supported for Pentium-m, so my CPU is always @1730MHz and hot, really hot.
- My sound card seems supported but I haven’t got any sound from it yet, I have seen in OpenSolaris forums I should install OSS for Solaris x86.
- I’m still trying to figure out how to play mp3 files without having to mess up my system, I was hoping adding some repositories would help on this one but no luck for me yet…
For now I haven’t got too much time for playing with it, but seems promising…I’ve been even thinking about migrate my current
Gentoo server to OpenSolaris but I will test it before doing it I don’t wanna spend much time for nothing…;)
After I started to use
OpenWRT/Kamikaze my WRT54GS has experienced some freezes, really annoying ones, so I decided to try out
DD-WRT.
I needed to flash DD-WRT from command line as I had my OpenWRT without any web interface so after some reading around I have finally deduced a way to do it:
OpenWRT# cd /tmp
OpenWRT# wget http://www.dd-wrt.com/dd-wrtv2/downloads/stable/dd-wrt.v23%20SP2/mini/dd-wrt.v23_mini_wrt54gs.bin
OpenWRT# mtd -r write dd-wrt.v23_mini_wrt54gs.bin linux
Once the router is rebooted, DD-WRT’s web interface can be accessed at http://192.168.1.1 … let’s the configuring begin!

Today I have figured out how to download from
megaupload without a Windoze machine.
What’s needed? just
Wine and
RapGet, configure you’re megaupload premium account (or rapidshare, etc) and start downloading whatever you want :).
HowTo?
$ wine RapGet.exe
And you’re done!

Z-push is a web application which will allow you to synchronize your Windows Mobile device against your own web server.
How to install it?
That’s an easy answer…just go to
its downloads section, get the latest tarball (at the moment of writing was version 1.0).
Untar it on your web server document root, modify the file config.php in order to meet your needs, I just changed the backend to IMAP cause by now it’s the only thing I can do, sync the mail.
Changes:
$BACKEND_PROVIDER = "BackendIMAP";
...
define('IMAP_PORT', 993);
...
define('IMAP_OPTIONS', '/ssl/novalidate-cert/norsh');
...
This changes are just cause I’m using IMAP over SSL so the port is not 143 and IMAP options for PHP module are ssl for using ciphered connection, novalidate-cert cause I use my own self-signed certificate and norsh to avoid authenticated rsh or ssh connections.
Once changes has been made, the last thing left is to add an alias to your
Apache configuration, it should look like:
Alias /Microsoft-Server-ActiveSync /path/to/document_root/z-push/index.php
Now it’s time for you to configure your Windows Mobile device against your web server, check
this document to see an example and for further references about z-push configuration.
Next thing will be to configure SSL in order to get my email through a secure channel.
So…you’ve got a bunch of
Red Hat servers and need to…save bandwidth? save licenses? or even don’t want your servers go to Internet? Then all you need is to create a yum mirror in order to keep them all up to date ;).
What do we need?
-
Apache.
-
mrepo.
- Some management licenses from Red Hat (these are needed if the system where you will hold the repositories is a different release from what you want to mirror.).
Let’s get started…
First we need to locate some space in order to hold all the RPMs we’re going to download, I have created a new logical volume with ~30GiB I hope it’ll be enough to have all the three mirrors I need.
The configuration for mrepo is found at /etc/mrepo.conf and will look like:
[main]
srcdir = /mrepo
wwwdir = /mrepo/www
confdir = /etc/mrepo.conf.d
arch = x86_64
mailto = root@localhost
smtp-server = localhost
rhnlogin = username:password
[rhel5es]
name = Red Hat Enterprise Linux $release Server ($arch)
release = 5
arch = i386
iso = rhel-$release-server-$arch-disc?.iso rhel-5.1-server-$arch-dvd.iso
metadata = repomd
updates = rhns:///rhel-$arch-server-$release
rpmforge = http://apt.sw.be/redhat/el5/en/$arch/RPMS.dag/
[4ES]
name = Red Hat Enterprise Linux ES $release Update 6 ($arch)
release = 4
arch = x86_64
iso = RHEL$release-U6-$arch-AS-disc?.iso
metadata = yum repomd
updates = rhns:///rhel-$arch-es-$release
rpmforge = http://apt.sw.be/redhat/el4/en/$arch/RPMS.dag/
[3ES]
name = Red Hat Enterprise Linux ES $release Update 9 ($arch)
release = 3
arch = i386
iso = rhel-$release-u9-$arch-as-disc?.iso
metadata = yum repomd
updates = rhns:///rhel-$arch-es-$release
rpmforge = http://apt.sw.be/redhat/el3/en/$arch/RPMS.dag/
The main section configures the environment for the local machine which will hold the mirrors, each of the next sections define the parameters for each release we’ll mirror. (Remember by now you should have installed mrepo, rpm -ivh mrepo-blahblah.rpm).
Once here, we need to create all the system identifications required for Red Hat to access to its repositories:
# gensystemid -u RHN_user -p RHN_password --release=3ES --arch=i386 /mrepo/3ES-i386/
# gensystemid -u RHN_user -p RHN_password --release=4ES --arch=x86-64 /mrepo/4ES-x86-64/
# gensystemid -u RHN_user -p RHN_password --release=5Server --arch=i386 /mrepo/rhel5es/
Now let’s suck from Red Hat:
# mrepo -ugvv (For getting everything)
# mrepo -ugvv repo_name (For just one repository)
The isos aren’t really needed but if you provide them will save some time to set up the mirrors. At this time we should configure our web server to allow clients access to repositories, I have created a virtual host called yum.domain.tld and looks like:
<VirtualHost *:80>
ServerName yum.domain.tld
DocumentRoot /mrepo/www
ServerAdmin admin@domain.tld
<Directory "/mrepo/www">
Options Indexes FollowSymlinks SymLinksifOwnerMatch IncludesNOEXEC
IndexOptions NameWidth=* DescriptionWidth=*
HeaderName HEADER.shtml
Order allow,deny
Allow from all
</Directory>
ErrorLog /var/log/httpd/error_yum.log
CustomLog /var/log/httpd/access_yum.log combined
</VirtualHost>
To finish this configuration we need to set up clients, we’ll install yum and its dependencies (python-elementtree, python-sqlite, python-urlgrabber and sqlite), all can be found at
Dag’s repository and configuration for our repository will be found in /etc/yum.repos.d/, it has to be called something.repo and will look like this:
[name]
name = Red Hat Enterprise $releasever
baseurl = http://yum.domain.tld/4ES-x86_64/RPMS.updates
enabled = 1
protect = 0
gpgcheck = 0
Once saved, just updating is needed:
# yum update
Well, that’s all…hope this will be useful!
UPDATE: I was having problems with 3ES servers asking for header.info file, they couldn’t find it on the mirror, after some messing around I did notice I haven’t had installed yum on the server, installing it solved the issue and now everything is working flawlessly.

It’s been some time since I tried previous versions of
Enlightenment, since then I have heard lots of good things about its 0.17 version (E17), so yesterday I decided to check it out.
Getting it installed on my
Sabayon was easy thanks to
Gentoo’s overlays. The process starts as follows:
# layman -a enlightenment
# emerge -Dpv e entrance
Here you can personalize your USE to fit your preferences…
# emerge -Dv e entrance
Then you’ll have to change your graphical login manager in /etc/conf.d/xdm:
DISPLAYMANAGER="entrance"
Reboot it and you’re done!
# /etc/init.d/xdm restart
Next time you login remember to select Enlightenment from session chooser

So again from
XDA-Devs we can now start testing Windows Mobile 6.1!
I have flashed this morning while having breakfast (:P)
Schap’s WM6.1 Pro 4.40 Beta for Kaiser, it seems quite fast, dunno yet about stability
WM6.1 it’s also available for HTC
Hermes and
Universal (sure it has to be for more devices but we just have those three at home :P)
Let’s flash!
