Installing a New Linux Kernel on Ubuntu 12.04

Installing a New Linux Kernel on Ubuntu 12.04 Whilst this may be common knowledge for those who have been working with Ubuntu for a while, it took me a few google searches to figure out, so here is the process I have settled on. sudo apt-get update # List available versions sudo apt-cache search linux-image-generic-lts[…]

VLAN Setup on Ubuntu 12.04

Ran into a situation recently where I needed to set up provider_vlan within OpenStack as well as configure the VLANs on the underlying hosts.

Vagrant, Chef, and the last 72 Hours

Ubuntu 12.04, DNS, and Static IPs

Having stumbled on the new /etc/resolv.conf methods of Ubuntu 12.04 a number of times, I hope this is useful for you as well. The contents of /etc/resolv.conf in Ubuntu are now controlled by “dns-nameservers #.#.#.#” in your /etc/network/interfaces file, like this: # The primary network interfaceauto eth0iface eth0 inet static    address 10.0.191.100    netmask 255.255.255.0    network[…]
