Network interfaces can be bonded to provide fault-tolerant operation. Here's how to do it in Ubuntu. I will assume the interfaces to be bonded are eth0 and eth1.

First, install the ifenslave package. The ifenslave tool will be used to actually bond the interfaces.

apt-get install ifenslave

First, let me tell you some first impressions about the machine. The keyboard is very good. It feels even a bit better than the one in my old T60. The display is very bright and sharp, but viewing angles could be better. WLAN worked right out of the box, as …

A backup server was saturating the DSL links of remote offices every time the backups were running. To prevent this, I had to limit the incoming bandwidth of the TCP-connections that were used to back up the remote hosts, but not touch the ones that were used to connect to …

I wanted to try out the Maemo SDK for Nokia 770, N800 and N810 devices (for some reason I happen to own one of every generation), but found out that there are no prebuilt packages for the 64-bit environment. The quick (?) remedy for this is the chroot jail, because a …

First, some empty disk space is needed. Let's create a logical volume for our new virtual machine:

root@xenserver1:~# lvcreate -n testlv -L 10G vg0
  Logical volume "testlv" created

Create a filesystem on the new logical volume:

root@xenserver1:~# mke2fs -j /dev/vg0/testlv
mke2fs 1.40-WIP (14-Nov-2006)

VMware Server needs exactly two kernel modules running on the host system (there are separate modules for guest systems). These are the vmmon and the vmnet modules. Unfortunately, the vmmon and vmnet packages included in the VMware server distribution package don't compile with the newest kernels. When I upgraded my …

A few months ago I released a script to install a 32-bit Adobe Flash plugin to a 64-bit Firefox, but it doesn't seem to work in Gutsy beta. Here's an updated one. I upgraded my laptop to Gutsy and used this one to get Flash working.

Edit: I did a …

A RAID array is a bunch of disks used together in co-operation to create a redundant storage facility. Hard drives are mechanical devices with moving parts, which makes them prone to failure. You can imagine what it means to spin the hard drive platters at 7200 rpm, for years without …

Here's a little script I made to make installing the 32-bit Flash plugin on a 64-bit Firefox easy. It was adapted from a script I found at the Ubuntu forums (here), but since that did not work right out of the box for me, I created one that does. The …
