Spent the morning setting up the router (using an LRP knockoff distribution of Linux called Coyote Linux) to have a secondary internal LAN connection. Used an old Intel EtherExpress 16 (not the PRO or PRO/100 ... this one's "Vintage" by Intel's standards). Also changed Jody's mods (which allow incoming connections on various ports) to use the IP address from the configuration file instead of his scheme of using the result of an "ifconfig eth0". This may not be correct if we go to DHCP, but allows the interface number to change and not break (a more likely prospect in the short term). Had to purchase a cross-over cable to connect the computer to the router. We now have a cable to allow visitors to use our cable-modem connection if they only have 10Base-T available (as the rest of the apartment is 10Base-2).
