Ha, ha ... like; I didn't know about any of this 2 days ago. Consider it forgot.

You have an ordinary SB5100 or SB5101 cable modem that has a LAN interface. (It also has a USB interface, but that cannot be used simultaneously with the LAN interface and is not the preferred way to connect to that modem.) What you need now is a router. It will allow up to 4 machines to talk to each other and also share the internet connection. They aren't terribly expensive -- $60 to $70 for a reasonably decent one. I'll leave it to others to suggest a model. It will almost certainly have WiFi capability, which you should turn off if you don't want to use it. (While you can get routers that do not have WiFi, consumer-grade routers that include WiFi are so much more common that you will likely pay more to not have that feature.)

Sounds like a plan. I'll check with my IP first. It could be they would substitute a multi etho port modem in their package as they do with my current modem. Its theirs; not mine. The single port one I have was all I needed until I got a new PC.

One last question;... my primary, perhaps exclusive, use for my old PC woluld be as a backup/storage for my Debian Docs & Sets. Currently I burn them to DVDs on a less than optimum basis because I find it a PITA. I still have more than 40 GBs of disk space available on that XP legacy drive. Exploring my options, if I disconnect my new PC from the modem, can it connect to the old unit on a project basis using a patch/crossover or other cable?

I appreciate your help and your savvy. Sorry if I didn't understand the modem was the key to understanding the issue. I figured there must be something peculiar with my PC. After all; you can't know what you don't know; eh?

Both can be made to work. I'd suspect the Intel is fully supported and only needs some ip address if you are not on dhcp. If not then set a static ip and some default subnet to use for the computer to computer connection.

From my earlier post:

AFAIK, my IP Address is assigned via DHCP; i.e., by my Internet Provider.

... so I don't think I have the option to set a static ip. A "default subnet" sounds really cool and techy; though. I want one.

Most users have a home router or modem that has public IP on the ISP side. Then internal side would have a private IP.

Use command ifconfig to tell maybe.

No matter what IP you have we can easily get a connection to other system.

jefro;
Riiiight! Now I gets it; I think. When I connect the new PC to the internet, ipv4 & 6 addies are assigned by my upstream provider via DHCP. The internal "lo" "Loopback" addresses "should?" be pre-determined/configured since I will be installing my current Deb7 HD as Master and the legacy Windows 8.1 HD as Slave.

Code:

#  /sbin/ifconfig
eth0      Link encap:Ethernet  HWaddr 00:11:11:55:80:42  
          inet addr:24.207.30.70  Bcast:24.207.31.255  Mask:255.255.252.0
          inet6 addr: fe80::211:11ff:fe55:8042/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

          <SNIP>                                                                                                                                                                       
lo        Link encap:Local Loopback                                                                                                                                          
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1 
<SNIP>

IF/as/when I connect the new unit to the old while having disconnected from the modem, I'll need to give it an address...

I never do what you have. I use a private IP from router/modem. No matter. Your setup does have a public IP address.

Yes, you'd have to assign a new IP. Some distro's will eventually put in a special IP range if no dhcp exists. In windows it's 169.x.x.x something. I think it's zeroconfig in linux but I forget.

It's pretty easy to put a new IP address in usually. Simple command for temp use is usually OK.

If you get IPv6 working correctly it should find local partners on it's own but that is a different can or worms.

Does your gateway/modem/router only have one connection for lan?

jefro:

I called my cable guy. They're going to sub-in a 4 port modem/router and install the crossover/switch cable. Problem solved. No charge.

'Domo arigato, Sensei'. Grasshopper go now.

rkn, michaelk:

'Mucho grazie'. I appreciate your help too. You taught me, led me to, a few new things.

Oh yes; ...and god bless the little children too.

Happy trails,
