netom's questions

I wish to use pvgrub.

I'm using debian wheezy x86_64.

I did an apt-get soruce xen and apt-get build-dep xen, cd-ed into the xen source dir and issued "make world".

The package doesn't compile, it emits the error message:

...
/bin/sh: 4: ./xen-setup-stubdom: not found
make[2]: *** [ioemu] Error 127
make[2]: Leaving directory `/root/install/xen-4.1.3/stubdom'
make[1]: *** [install-stubdom] Error 2
make[1]: Leaving directory `/root/install/xen-4.1.3'
make: *** [world] Error 2

Does anyone know what might be wrong?

Thank you.

I'm trying to set up a ganeti cluster.

My problem is that I don't understand the role of the "cluster name" and the associated "master IP".

The installation requirement is that every node and future instance must have a resolvable host name, and the cluster name must be resolvable too.

What IP address should I assign to the cluster name? What it'll be used for?

Thank you in advance.

I have several users on a computer running Linux (Ubuntu Lucid to be more specific).

I need to see how much network traffic they generate on a specific interface.

Iptables can match outgoing packages, so I could create chains for every user to be able to count outgoing network traffic. However, incoming traffic is significant too.

I have several options: -Writing a new iptables match for incoming packets -Writing a new iptables module that combines outgoing packet user match and connection tracking -Writing a TUN/TAP driver that somehow able to identify the sender / receiver process and user, and write a log -...

What is the best way to do this? Are there any existing solutions for this?

Thank you in advance.
