As I was wondering about IPv6 and because my current host (www.slicehost.com) doesn’t have native support, I decided to try out a 6to4 on my box.
Basically, a 6to4 is a system that allows IPv6 packets transmitted over IPv4 network (IPv4 Internet). (see: http://en.wikipedia.org/wiki/6to4)
You may or may not know this before, there is a utility named apropos, which enables you to search within you man pages installed on your system. Which is infact very usefull when you know what you are about to do, but no clue about with, and where.
For example:
$ apropos ethernet ethers (5) - Ethernet address to IP number database ethtool (8) - Display or change ethernet card settings sk98lin (4) - Marvell/SysKonnect Gigabit Ethernet driver v6.21
or;
$ man -k ethernet ethers (5) - Ethernet address to IP number database ethtool (8) - Display or change ethernet card settings sk98lin (4) - Marvell/SysKonnect Gigabit Ethernet driver v6.21
The real problem here is (for me at least), “apropos” is real hard word to remember itself and it’s a bit ironic when you think of its purpose. So I think, may be writing a post about it helps me to remember it better.
I’ve recently installed Ubuntu 9.04 (Jaunty Jackalope) on my Thinkpad, and guess what, according to the article at https://wiki.ubuntu.com/X/Config/DontZap Ubuntu people decided to disable the Ctrl + Alt + Backspace combination, which kills the X instantly.
Ok, there is a logic behind the idea, but what about giving user the freedom of choice?
Long story short, you can re-enable the beloved key combination, just edit your /etc/X11/xorg.conf and add the following lines:
Section "ServerFlags" Option "DontZap" "False" EndSection
Ok, it is announced for a while ago, early last month to be specific. So sorry for the late info.
But, the point is, with 2.2, a new interface type comes: Host-Only Interface (with many other bugfixes and new features, offcourse). And so my post about “Simple Network Setup On VirtualBox 2.1” is obsoleted. Just select the Host-Only Interface option on your virtual machine settings.
PS. By default, virtual box runs a dhcp server serving 192.168.56.0/24 network to host-only interfaces. You can alter the default from VirtualBox Preferences.
I’ve been using linux-vserver for the past few years, but as there is no linux-vserver kernel for ubuntu and I don’t want to give my time re-compiling kernel, I’ve decided to try alternative virtualization solutions. I’ve already tried qemu, vmware but i really don’t like them. So I gave a shot to VirtualBox.
After trying and seeing the mess on setting up network properly on virtualbox-ose, i was a little bit disappointed. But as VirtualBox 2.1, they seem to fix lots of problems with network utilization. Read more »
