[Lancaster] Simple network

[Ken Hough]

Rick, Gus,

If you are going to connect two machines directly via ethernet, you will need 
to use a "crossover" ethernet cable, or an ordinary cable plus a crossover 
adaptor.

Also bare in mind that  you might not/probably won't have a DHCP server 
running on one of these machines, so you might want to set up static IP 
addresses on both machines.

Otherwise the simplest setup is to use an ethernet switch/router. As Gus 
mentioned these usually include firewalls. Typically these also include a 
DHCP server, so you won't need to set up static IP addresses on your 
computers.  But, if this is to be a fairly permanent setup, you might still 
find it worth while to set static IP addresses on your two computers. Just 
mind that these don't clash with address range that the DHCP server dishes 
out.

As Gus mentioned, depending on what services/protocols you wish to share, you 
might need to faff around with firewall settings.

Once you have established that the two computers are linked (try 
using 'ping'), if other services don't appear to work, then TEMPORARILY 
disable the firewall(s) and re-check.

Good luck
