Guide to the network at the NYC apartment of Thomas Krichel

The machine in the cupboard is called chichek.openlib.org. Chichek has two PCI 10/100 Ethernet interfaces. On chichek, the configuration is

## The interface to the lower card
auto eth1
iface eth1 inet static
  address 192.168.34.1
  network 192.168.34.0
  netmask 255.255.255.0
  broadcast 192.168.34.255

## The interface to the upper card
auto eth2
iface eth2 inet static
  address 192.168.12.1
  network 192.168.12.0
  netmask 255.255.255.0
  broadcast 192.168.12.255

The cable out of the built-in interface goes to cable modem. It must not be disconnected, otherwise connection to the Internet will be lost.

To obtain connection to the lower interface, you need to give a configuration such as, for a Linux style interfaces file where eth0 is the interface you want to use

auto eth0
iface eth0 inet static
  address 192.168.34.34
  netmask 255.255.255.0
  gateway 192.168.34.1
  broadcast 192.168.34.255
  dns-nameservers 192.168.34.1
  dns-search openlib.org

Idem, this is the one for the upper interface

auto eth0
iface eth0 inet static
  address 192.168.12.12
  netmask 255.255.255.0
  gateway 192.168.12.1
  broadcast 192.168.12.255
  dns-nameservers 192.168.12.1
  dns-search openlib.org
