Ubuntu Cleanup

There is an excellent article on Ubuntu Genius on how to clean Ubuntu’s Unused Linux Kernel Headers, Images and Modules.   While I have been using Linux, Unix and every operating system you can imagine for years, I had no idea this command could do this for Ubuntu- then again, who would - excellent article -

(Run in a terminal window) – Be sure to read the article and paste the recommended code from his article.

MTU Settings for Ubuntu

Setting your MTU settings adjust your internet connection.  With my connection, a default setting of 1500 causes some webpages not to display at all (i.e. Ebay, Microsoft, etc.)

My optimal settings are 1492 to change yours, open a terminal and type:

sudo ifconfig eth0 mtu 1492  (that is eth and zero)

When you reboot, the MTU will return to 1500 – to make it permanent you will need to edit one of Ubuntu’s files:

First type -

sudo gedit /etc/network/interfaces

Then carefully edit your file

iface eth0 inet static
mtu 1492

You should now restart your network with:
sudo /etc/init.d/networking restart

Check the new value type:
sudo ifconfig -a
