configure and use the server as a gateway to control thin client access to the
Internet. To do this, the server must have two network cards, and we again
recommend that the one used to connect to the switch be a Gigabit card; all
the thin client traffic has to travel between the switch and server over that one
connection, so a Gigabit card will cause fewer bottlenecks than if you have
multiple clients connecting to a switch at 100Mbps trying to share a single
100Mbps connection to a server. The card from the server to the Internet
router should be adequate for the Internet connection available, but there is no
reason to put anything faster in there. If you have only a 100Mbps connection
with your Internet service provider, using a Gigabit card will not provide any
particular benefit.

LTSP Installation
After you decide how you want to set up your network and connect all the
hardware, you can get to the task of installing the software. In Ubuntu, the
LTSP software is available for installation in two ways. If you are repurposing
a server that already has a current release of Ubuntu installed on it, you install
the ltsp-server-standalone and openssh-server packages from
the Ubuntu repositories and run the following to set up the environment:
