Ubuntu PPTP VPN  

This tutorial describes how to enable PPTP VPN log ins to your local network from an external network.

Ubuntu Serial Console Login  

If you have a headless machine, as is the case with many serviers, it is often nice to be able to see what's going on without having to connect a monitor and a keyboard to the system.  In this short tutorial we'll show you how to configure the serial port on your server, or Desktop, machine to allow you to view the console though it.

  • You have enabled the serial console in your BIOS
  • The serial connection is being made at 115200 baud 8n1, on first serial port, called /dev/ttyS0 in linux (9600 8n1 is the default fall back if your hardware does not support 115200 baud)
  • You are comfortable editing critical system files such as /etc/inittab, /boot/grub/menu.lst
  • You are using a serial (null modem) cable. It is also possible to use a USB to Serial adaptor, but the tty* must be changed to reflect your hardware.
Ubuntu Server Static IP  

Sometimes the things that seem the most obvious are the most difficult to get to work.

If you plug in the values for your local network, you should be able to cut and paste.

Local Domain:		
Local Search:		
Domain Name Server:		← External domain name server address.
Wide Area Network:
	Address:		← Your Static IP (from Your ISP).  Start here.
	Netmask			← Here next.
	Network:		← Calculated.
	Broadcast:		← Calculated.
	Gateway:		← Best guess, replace with ISP's value.

In order configure your Ubuntu server for a static external IP address, you will have to change '/etc/network/interfaces'.  So lets back it up:

cp /etc/network/interfaces{,.`date +%F`.BU}

Now open '/etc/network/interfaces' and add the following:

# The primary network interface
auto eth0
iface eth0 inet static
