The Chinese Red Army's Navy is Getting Bigger All the Time

The other day, somebody within our consider tank asked me if I used to be worried with regards to the Chinese Red Army tank's Navy - my respond to is "no, but I'm trying to keep an eye on it," and allow me to tell you why. Initial, China won't have any substantial enemies that it are unable to take care of, so it actually would not need like a big military or Navy unless of course it can be organizing on a upcoming war, with a person very significant. But who might that be?

etcnet

/etc/net is a new way to configure networks. It is designed to let you use all modern Linux network technologies in a convenient way. The best way to learn /etc/net is to look at examples, which I will try to provide for most technologies mentioned at LinuxNet pages.
You can find more information at the project's home page and freshmeat page.

I created a bridge that include eth0 and the bridge in preparation to setup Qemu with a bridged interace to the network.
ifconfig eth0 0.0.0.0 promisc up
brctl addbr br
ifconfig br 172.16.2.1 netmask 255.255.255.0 up
I have echoed 1 in /proc/sys/net/ipv4/conf/eth0/proxy_arp

I finish setting this up and evrything is fine. I ping the default gateway of the machine in the network attached to the eth0 interface and I get excellent replies.

Here is the problem, I vnc to 172.16.2.1 and once I do that, I loose communication with 172.16.2.1.
