General Hints & Tips

Upgrades

Unattended upgrades are now possible and make it easy to keep your system updated with ZERO user involvement.

sudo aptitude install unattended-upgrades
sudo dpkg-reconfigure -plow unattended-upgrades

See /usr/share/doc/unattended-upgrades/README for other interesting details.

Bonding interfaces

First install ifenslave before screwing up the network :)

aptitude install ifenslave

This can be put into /etc/network/interfaces to bond two ethernet interfaces. Don't forget to remove the (individual) entries for eth0 and eth1.

auto bond0
iface bond0 inet manual
  address 10.1.1.2
  netmask 255.255.255.0
  gateway 10.1.1.1
   post-up ifenslave bond0 eth0 eth1
   pre-down ifenslave -d bond0 eth0 eth1

Add this to /etc/modules and reboot

bonding mode=active-backup miimon=100

VLAN interfaces

To create a (tagged) vlan interface on top of a bonded interface, add 8021q to /etc/modules and modprobe 8021q.

Then add something like this to the /etc/network/interfaces

# VLAN10 
auto vlan10
iface vlan10 inet static
   address 10.1.10.2
   netmask 255.255.255.0
   vlan_raw_device bond0

Notice how the last line vlan_raw_device indicates which "physical" interface this tagged interface should communicate through.
