resizing a linux partition with ubuntu

source: http://askubuntu.com/questions/116351/increase-partition-size-on-which-ubuntu-is-installed

As a matter of fact, you CAN enlarge the root filesystem while Ubuntu is running (I learned this recently myself here) - this sounds incredible but it's true :)

Here's the list of steps for a simple scenario where you have two partitions, /dev/sda1 is an ext4 partition the OS is booted from and /dev/sdb2 is swap. For this exercise we want to remove the swap partition an extend /dev/sda1 to the whole disk.

1. As always, make sure you have a backup of your data - since we're going to modify the partition table there's a chance to lose all your data if you make a typo, for example.
2. Run sudo fdisk /dev/sda
   • use p to list the partitions. Make note of the start cylinder of /dev/sda1
   • use d to delete first the swap partition (2) and then the /dev/sda1 partition. This is very scary but is actually harmless as the data is not written to the disk until you write the changes to the disk.
   • use n to create a new primary partition. Make sure its start cylinder is exactly the same as the old /dev/sda1 used to have. For the end cylinder agree with the default choice, which is to make the partition to span the whole disk.
   • use a to toggle the bootable flag on the new /dev/sda1
   • review your changes, make a deep breath and use w to write the new partition table to disk. You'll get a message telling that the kernel couldn't re-read the partition table because the device is busy, but that's ok.
3. Reboot with sudo reboot. When the system boots, you'll have a smaller filesystem living inside a larger partition.
4. The next magic command is resize2fs. Run sudo resize2fs /dev/sda1 - this form will default to making the filesystem to take all available space on the partition.

dns ip wildcard resolver

This took me a long time to find. Figured that I should post it before I lost it AGAIN!

This basically gives you the ability to host multiple hostnames on a single computer by using a 4 level domain name with the third level being your local internal ip address.
i.e.
http://something.10.0.0.100.xip.io/ and http://somethingelse.10.0.0.100.xip.io
