1. This file describes the network interfaces available on your system
2. and how to activate them. For more information, see interfaces(5).

1. The loopback network interface

auto lo iface lo inet loopback

1. The primary network interface

auto eth0 iface eth0 inet static

address 172.26.145.104
   netmask 255.255.255.0
   gateway 172.26.145.251
   dns-nameservers 8.8.8.8 1.1.1.1

1. post-up ethtool -K eth0 tx off

2. The commented out line above will disable TCP checksumming which
3. might resolve problems for some users. It is disabled by default
