HOWTO Use Ubuntu As A Mac OS X Time Capsule
location: ubuntuforums.com - date: January 17, 2013
In past versions of Mac OS X, the built in backup tool, Time Machine was a lot less picky about where you back up your files to. You could even back up to a Samba file share if you enabled the "unsupported volumes" hack.
defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1
But that ended with Snow Leopard. Starting with the release of OSX 10.7 Lion, Apple started cinching down on where you could back up your system to, ostensibly for security reasons. Now, with Mac OS X 10.8 "Mountain Lion", it's gotten to the point where essentially the only places you can back up your system using Time Machine are either on another Mac OS X File Server or on an Apple Time Capsule. My assumption is that their intent is merely to bolster their hardware sales.
I don't know too many people who stay exclusively within the "walled garden" for all their computing needs. Certainly people with a lot more money to burn than me.
HOWTO: Create 12.04 Persistent & Backtrack 5 USB
location: ubuntuforums.com - date: April 30, 2012
Hey all, I just wanted to share the process I went through to somehow put together a working USB that can dual boot BackTrack 5 and Ubuntu 12.04, with ubuntu being persistent as well.
This IS a manual procedure since tools like Unetbootin and the provided usb creator on ubuntu cannot dual boot systems, and they use syslinux. I used GRUB to get mine working.
I don't really know what goes on behind the scenes in GRUB, or ubuntu's boot up process. I pretty much made this by pulling info from different guides and forums on the web, including A better way to create a customized USB drive with Ubuntu Live on it (and the comments at the bottom), this thread, and this for reference.
This is what I started with:
Ubuntu 12.04 iso BT5 R2 iso 16 GB flash drive GRUB2 for the booting stuff
Here's what I came up with...
Drawing from the info in the first link (which is slightly outdated but still mostly works except for an old version of GRUB), here's the general layout of my stick:
HOWTO: Customizing bash prompt
location: ubuntuforums.com - date: November 16, 2007
The information in this thread has been moved to https://help.ubuntu.com/community/CustomizingBashPrompt
A thread for discussion of the wiki page only can be found here http://ubuntuforums.org/showthread.php?t=2012407
If you have difficulties using the terminal because the prompt isn't visible enough or you would simply like it to look nicer, this howto is for you. It should work on any distribution if you use bash shell, just don't expect your existing .bashrc file to look like Ubuntu's. I've attached a before and after picture of my terminal as an example of what you could do.
So let's get started. Fire up your terminal and stay in your home directory.
First, let's backup our .bashrc file since we're about to make some changes to it:
cp .bashrc .bashrc-backup
The .bashrc file tells bash what to do when terminal is started, including how to show prompt.
2. Preparing the .bashrc
Use your favorite text editor to edit the original .bashrc fi
[SOLVED] Howto install an Ubuntu server as a virtual server on a Cent OS 5.6 host.

Is it possible ?
I've tried to install it as fully virtualized, but alot of errors occurs during installation.
Using para-virtualization wont even start the installation. Errors on media contents, something like that.

Howto bridge wireless and wired network interfaces?
location: linuxquestions.com - date: October 3, 2005
First of all I hope this topic was not covered already elsewhere, but I couldn't find a solution with searching Google and Linuxquestions.org. I also want the debian way via /etc/network/interfaces for my new setup.
The following setup is working without any problems and is faily easy to setup. My Laptop is connected to the university network via wired ethernet eth0 and gets an public IP address from the university DHCP server:
iface eth0 inet dhcp
name Ethernet LAN card
The wireless network eth1 is setup as an ad-hoc network with an private IP address and another DHCP server running on my linux box assigns a private IP address to any computer which connects to my ad-hoc network (primarily for surfing the internet from the kitchen, which has no network socket). The package ipmasq does network address translation (NAT) for the wireless host connected to the ad-hoc network.
iface eth1 inet static
name Wireless LAN card
HOWTO: NoCD FreeBSD/NetBSD Installation From Windows or Linux
location: ubuntuforums.com - date: February 1, 2008
This guide is for anyone who wants to install FreeBSD or NetBSD without using any external media, such as a CD, Floppy, USB-Drive, or the like. It uses UNetbootin to chainload off the host OS's bootloader (via GRUB4DOS on Windows, and GRUB on Linux), and load the installer for FreeBSD/NetBSD, so that installation can continue via the standard FTP-install approach, or through predownloaded packages on a partition.
Supported *BSDs to be installed: FreeBSD 7.0, FreeBSD 6.3, NetBSD 4.0
Supported OS's to be installed from: Windows, Linux
1. Navigate here and pick the appropriate OS to install. Direct links are here: FreeBSD 7.0 FreeBSD 6.3 NetBSD 4.0
Instructions for Windows
If using Windows, download the .exe version for whatever OS you want to install, and reboot when prompted. Select the UNetbootin boot option on the next reboot, and it'll launch the FreeBSD/NetBSD installer. After that, just follow the standard installation instructions.
HOWTO: Share Firefox/Thunderbird profiles between *buntu/Windows/OS X
location: ubuntuforums.com - date: April 26, 2009
Disclaimer: This is meant to provide general instructions on how to share your Firefox/Thunderbird profiles between operating systems on multi-boot systems. It assumes you know the basics for sharing files/folders between the different operating systems on your computer, as well as the basics for copying/moving files/folders and navigating within the different operating systems. You could theoretically share the profiles between multiple computers across a network, but that is beyond the scope of this post.
When I first started using Ubuntu I dual-booted with Windows XP because some programs/devices I used weren't supported in Linux well enough. Back then my main pet peeve was that all my Firefox bookmarks and Thunderbird email was on my XP partition. It was annoying trying to keep them both up to date. So I found out how to share the profiles between the 2 operating systems.
Just a note here, since the instructions for doing this with Firefox and Thunderbird are essentially t

HowTo: UFW Ucomplicated Firewall
location: ubuntuforums.com - date: June 9, 2008
I looked for a current how-to for UFW and when I did not see one I wanted to add one.
(important note: UFW is not the firewall. UFW just configures your iptables)
in most cases I recommend doing the following immediately:
sudo ufw default deny
sudo ufw enable
Then fine tuning can start:
Some basic commands are:
Turn on the firewall
sudo ufw enable
Turn off the firewall
sudo ufw disable
To add deny rules:
blocking a port
sudo ufw deny port <port number>
blocking an ip address
sudo ufw deny from <ip address>
blocking a specific ip address and port
sudo ufw deny from <ipaddress> to port <port number>
advanced deny example for denying access from an ip address range 10.120.0.1 - 10.120.0.255 for SSH port 22
sudo ufw deny from 10.0.0.1/24 to any port 22
To add allow rules:
to allow an ip address
sudo ufw allow from <ip address>
to allow a port
