Capture

Installing uml_switch with capture-from-host option

In order to install Esteban Martín's modified uml_switch to allow capturing traffic in virtual networks directly from the host, follow this steps (tested in Ubuntu 6.06):

• Install development tools (compiler, etc) and capture library :

 apt-get install build-essential
 apt-get install libpcap0.8-dev  

• Download vnuml source.

• Uncompress it:

 tar xfvz vnuml_1.7.2.orig.tar.gz
 cd vnuml-1.7.2

• Access to uml_switch directory:

 cd contrib/uml_router

• Compile it:

 make

• Copy the executable to system directories (use a different name for uml_switch in order to not overwrite the original):

 cp uml_switch /usr/bin/uml_switch4capture
 cp umlctl umlswctld /usr/bin/

• Include uml_switch_binary parameter in the <net> tag you want to capture on:

 <net ... uml_switch_binary="/usr/local/bin/uml_switch4capture" />

You can find more information in README file inside contrib/uml_router directory.
