NEW:

Beem:

-pozrel som si empiho pouz. a syst. prirucku, nainstaloval chybajuce kniznice, skompiloval a spustil beem

$ sudo apt-get install libpcap0.8 libpcap0.8-dev

 $ sudo apt-get install libpcap0 libpcap0-dev 

$ sudo apt-get install libxml2 libxml2-dev

-tak som do repozitarov (/etc/apt/sources.list) pridal jeden zdroj:

-zrejme sa snazi cosi odchytavat na rozhrani eth3, ale to tam zjavne nie je, zrejme sa to tyka nejakeho configu... kazdopadne ja do toho zatial hlbsie nevidim, takze ocenim vsetky pripomienky a rady (co s tym, ako postupovat dalej, atd.)

(pozn. bezi vobec na qos-meter.cnl.tuke.sk nejaky traffic, ktory by sa dal merat?)

EDIT:

-v configure.xml zmenene interface na eth0:

<interface>eth0</interface>

<collector>
     <version>10</version>
     <host>127.0.0.1</host>
     ...       
</collector>

pozn.: $ ./beem potrebne spustat pomocou "sudo", inac to vyhodi tento error:

$ ./beem
...
[error]:capture.c:401: socket: Operation not permitted
...

$ sudo ./beem

Collector:

Ako prve treba nainstalovat Javu. Z repozitarov pre Etch je to easy.

Do /etc/apt/sources.list pridame

#Etch
deb http://ftp.us.debian.org/debian/ etch main contrib non-free

$sudo apt-get update

$sudo apt-get install sun-java5-jre

$java -version
java version "1.5.0_10"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_10-b03)
Java HotSpot(TM) Client VM (build 1.5.0_10-b03, mixed mode, sharing)

Potom bolo treba zmenit prava na subor JXColl-linux

kudla@qos-meter:~/zzz$ sudo chmod go+x JXColl-linux

Nestaci to spustit takto (sudo netreba):

kudla@qos-meter:~/zzz$ ./JXColl-linux JXColl.conf
Unable to find a supported JDK or JRE version. Version 1.3.1 or higher is required.
Check your installation and use +javahome to specify the JDK or JRE location

Prva moznost je pri kazdom spusteni na koniec pridat toto:

kudla@qos-meter:~/zzz$ ./JXColl-linux JXColl.conf +javahome /usr/lib/jvm/java-1.5.0-sun-1.5.0.10/jre/

Druha moznost (permanentne riesenie) je podla tohto navodu upravit subor .bashrc:

To add the bin directory of the jdk to your own PATH, for your own work, try the following inside a bash shell:

1) Change into your home directory - cd $HOME

2) Open the file ".bashrc". I recommend vi for simplicity here - vi .bashrc

3) Add the following line to the file. Replace the term (jdk directory) with the name of your java installation directory

export PATH=/usr/java/(jdk directory)/bin:$PATH

5) Use the "source" command to force linux to reload the .bashrc file which normally is read only when you log in each time - source .bashrc

6) You can test your PATH setting by checking for the version - java -version

Note that if you wish to set the PATH setting for all users of the system, you will want to log in as root in the bash shell and perform the same steps upon the file "/etc/ profile" rather than ".bashrc" in the home directory. Careful when editing system files. It's a good idea to make a backup of the file first just in case.

V nasom pripade to nie je jdk ale iba jre, ale to je jedno. Takze na koniec suboru .bashrc pridame tento riadok:

 
export PATH=/usr/lib/jvm/java-1.5.0-sun-1.5.0.10/jre/bin:$PATH

Najprv spustame Collector a az potom Beem (exporter), lebo tento hned na zaciatku posle sablonu (template) a potom uz len data.
