 In the above example "address 192.168.1.60" is a static IP address for the BBB, which will allow incoming network traffic to be directed from the router in a reliable manner.  It should be outside of the DHCP range set up on the router.

 Now disconnect the BBB from your computer and plug it into the router. You'll need an ethernet patch cable and you may also need a 5V/1A power supply for the BBB.

-** Create a swap file
-
-Without a swap file the system may occasionally run out of memory and crash, since the Beaglebone only has 512MB of RAM.  The following commands will create a 1GB swap file:
-
-#+BEGIN_SRC: bash
-mkdir -p /var/cache/swap/
-dd if=/dev/zero of=/var/cache/swap/swapfile bs=1M count=1024
-chmod 600 /var/cache/swap/swapfile
-mkswap /var/cache/swap/swapfile
-swapon /var/cache/swap/swapfile
-#+END_SRC
-
-To tell the OS to load this swapfile on each start up.
-
-#+BEGIN_SRC: bash
-emacs /etc/fstab
-#+END_SRC
-
-Append the following line:
-
-#+BEGIN_SRC: bash
-/var/cache/swap/swapfile    none    swap    sw    0   0
-#+END_SRC
-
-Then save and exit.
-
-To verify that the swapfile is accessilble type /top/ and look for the line which begins with "KiB Swap".  Probably there will be zero bytes used, but this might be non-zero when the system is under some load (for example getting a lot of web views or being crawled by a search engine). CTRL-C exits from the /top/ command.

 ** Enable backports
 
 To enable some newer packages add backports to the repositories.
