Ubuntu Linux

As of December 2006, Ubuntu Linux is the #1 most popular distribution on distrowatch.

Ubuntu is based on Debian just like some other popular distributions like Knoppix. The installer is likewise based on the debian installer.

Hardy Hints & Tips

DVD Playback

Getting error "Could not read from resource"? See here

These are the steps I tried...

1. Run these commands

aptitude install totem-xine regionset
sudo /usr/share/doc/libdvdread3/install-css.sh
regionset
(choose 1)
totem-xine

1. Now totem (movie player) is running
2. Select Movie->Open Disc 'Movie Title'
3. Examine console for output

General Hints & Tips

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 , put 8021q into /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.
