I am a newbie to networking and am keen to learn networking in linux. The only resource i have is a single computer.Is it possible to setup and test firewalls and mail servers and other servers only using a single comp using the loopback address.Or can i try using two network cards on a single comp? Can I assign two ip address to a single ethernet interface.Please let me know if i can learn using a single comp as i cannot afford to join any course or purchase another comp to learn it.

TIA, Pankaj

Pankaj,

you can create your own virtual infrastructure on single PC provided you have good configuration, try vmware http://www.vmware.com/
