From memory you can set an +address for an ethernet card with something like; + +ifconfig eth0 192.168.0.22 + +That implicitly brings up the connection. + +This much is already working for you as you say both PCs can reach the +internet. So let's take a step back. I don't want you to "publish" +your PC addresses, but if they are both on the same network then they +should both have addresses in the private network ranges. The most +common on routers are; + +10.?.?.? +192.168.?.? + +If they have some other address range then they are likely to be +publicly accessible and there is no Network Address Translation being +carried out by your router. + +Can you configure your router? Do you know if it has a web-based +configuration address? If you haven't come across this before, this is +a "web page" generated by your router which provides access to its +configuration by means of forms on web pages. It is normally accessed +by entering the address in your browser, but this cannot easily work +if your PC and your router are on different networks, with different +address ranges. For example, the router might be on 192.168.1.1 and +your PC is on a.b.x.x where a and b are NOT 192 and 168. + +Let us take one more step back. When you configured your network on +each computer (using MCC?) did you opt for manual or automatic (via +DHCP) configuration of the network address? That, I think, is the key +starting point. + +If it is manual then you chose the addresses and typed them in. If it +is automatic (via DHCP) then they will have been allocated by EITHER +your router (which seems unlikely given the trouble your having) OR by +your ISP, and that means they are permitting you to have more than one +public address for your location AND that the address really is +public; if I knew your address I could probe your network - that is +potentially highly risky and is why the common practice, in these +parts, is for each subscriber to get one public address and have the +modem/router provide NAT for private networks on the premises. + +I hope I haven't confused the issue. Let me re-state the important questions: +1. Are your PC addresses similar to each other? +2. Are they in the private network range? (10.?.?.? or 192.168.?.?) +3. Do you have the make and model of your router? (yes/no will do for now.) + + +Richard + + + +On 05/03/2012, e-letter <<A HREF="https://www.mageia.org/mailman/listinfo/mageia-discuss">inpost at gmail.com</A>> wrote: +><i> On 05/03/2012, <A HREF="https://www.mageia.org/mailman/listinfo/mageia-discuss">mageia-discuss-request at mageia.org</A> +</I>><i> <<A HREF="https://www.mageia.org/mailman/listinfo/mageia-discuss">mageia-discuss-request at mageia.org</A>> wrote: +</I>>><i> ------------------------------ +</I>>><i> +</I>>><i> Message: 4 +</I>>><i> Date: Sun, 4 Mar 2012 22:33:07 +0000 +</I>>><i> From: WALKER RICHARD <<A HREF="https://www.mageia.org/mailman/listinfo/mageia-discuss">richard.j.walker at ntlworld.com</A>> +</I>>><i> To: Mageia general discussions <<A HREF="https://www.mageia.org/mailman/listinfo/mageia-discuss">mageia-discuss at mageia.org</A>> +</I>>><i> Subject: Re: [Mageia-discuss] home network using broadband router +</I>>><i> +</I>>><i> Hi, I'm no network expert but I have some practical experience with +</I>>><i> home networks. +</I>>><i> +</I>>><i> The first thing I would do is check the IP addresses on your home +</I>>><i> computers.
