Since long I have a home network consisting of two computers connected with a twisted cable. They have the addresses 192.168.0.1 and 2 and are on eth0. As I am preparing for an ADSL connection I already have added an other Ethernet card as eth1and an ADSL 4 port router. It is not (yet) planned to let the second computer on the Internet. As I suspect that the fellows who are coming to my place to install the ADSL are complete ignorants of a system which does not belong to Win***s I want to be prepared to interfere myself. The problems lies in the fact that I do not understand a jota about the whole thing although I have RTFM and more ;-(. In the eth0 setup I have used the static address setup 192.168.0.1 In the setup for eth1 I have used the automatic address setup (via DHCP) Right or wrong? Under Host name and server I have for the moment under hostname the name of the computer (bigone) and as domain name my home network (constant.net) The button "Change host name via DHCP" is not in use. Right or wrong? Under name server there is the proposed address (I think from the router) of 10.0.0.2. I assume that the technician of the telephone company may have its own idea of an address. Other name server numbers are empty. Under domain search I find constant.net and suse.com. What should here be inserted/changed? The button "Update name servers and search list via DHCP is in use. I assume that in Kmail I use the pop and smtp setup as with the dialup. Right or wrong? For completeness sake, I am using 9.0 and may switch to the also installed 9.2 or a not yet installed 9.3. I am using KDE as my email client.

I suspect your 4 port router contains a dhcp server, (because its hard to find one of these that does not contain such a thing). If so just set your computers to get their ip via dhcp. In fact you can test this bit before the adsl dude gets there because the router does not need a internet connection to allow you to create your local network. The router can usually be configured by pointing your web browser to what ever your own IP (except a 1 in the last octet). -- _____________________________________ John Andersen

No, I'm talking about the last octet of the IP your router gives to each machine, not the IP your ADSL modem gives the router. The Router will get its IP from the modem. Don't worry about that. The Router will hand out IPs to any machine connected ti the 4ports that requests one.
Another (stupid) question: do I need those two ethernet cards (homenetwork and ADSL) and do I need to connect them both to the router?
You should only need one Ethernet card per machine. Two won't buy you anything. Each machine plugs into the router. All the machines plugged into the routers 4 ports will be able to see each other, and access the internet via the router's other port - the one that connects to the ADSL. (To add one more layer of confusion to the mix... MANY, (but not all) ADSL modems come with a built in router and 4 ports. In this case you will not really need a separate router. )
I assume that this computer can than be used as server and could then allow the other computer on the homenetwork to get access to the ISPvia the router. Is that correct?
Essentially, yes. The router also acts as a hub so all your machines can "see" each other. (Microsoft calls this the Network neighborhood. ) You can share printers, etc. But one step at a time.... Computers Plug into the Router, Router Plugs into the ADSL Modem, ADSL modem plugs into the phone line ... Nothing But Net! ;-) -- _____________________________________ John Andersen

Tried it out and doing a ping to the other computer my computer started dialing. The other computer was hapely pinging.

Does that mean that I do not have to give my computers names and an address? Up to now in /etc/hosts I had to have the names and addresses. Or does that not change?

Sure and it seems easier than I thought. The two computers are talking again with each other and I wait for the technical fellow to mess everything realy up ;-) Hope you will be around to help me out.

The host name assigned by your ISP, will be for the router, not any computer behind it. You'll still need your hosts file or local dns. Also, in Yast, when you configure dns, add your ISPs domain to the domain search.

To make a long story short, the connection is there. Do not know how they did it but I am connected to the ISP from the telephone company and use that to send my email. To receive I am connected to my old ISP and it seems to work. But I do not see my other computer which is connected to the modem router also. How do I add that to the setup? And why is there only a ADSL watch program for CAPI modems? I see the activity of the ethernet card in Gkrellm but I would like to see more about what is going on.

Normally, the host name is assigned by the ISP, so you'd want to enable "Change host name via DHCP". Also becareful with the static address on eth0. It might conflict with the router.

No, thats just wrong. Your host name should never be assigned by the ISP, and you want to specifically disable this. Its wrong enough for windows but its totally wrong for Linux. Further since he is behind a router and gets his IP from the router not the ISP, this is completely off base. -- _____________________________________ John Andersen

When I first replied to that note, I missed the part about the ADSL router. I had assumed he was building a Linux firewall. That said, the device connected to the ISP, gets it's name from the ISP. This is neccessary, if you want to access your system remotely, using the host name, as assigned by the ISP. I realize that this won't work well with some ISP's who derive the host name from the IP. With my ISP, the host name is derived from the computer & modem MAC addresses and is static (my IP is virtually static). Of course, any computer behind the firewall/router gets a locally assigned host name.

You should always disable this feature in your dhcpc config. All the hardware routers I am aware of allow you suppress this behaviour.

And why would you want to do that? Have you never heard of dynamic dns? With something line dyndns.org , you can find your computer from anywhere even if you have a dynamically assigned IP. In the last 8 years I've saved over 6 thousand dollars by NOT paying my ISP for a dynamic IP on several boxes that I need to manage remotely. Its essential to never allow my ISP to change my host name. Screws up MTAs and all sorts of things. -- _____________________________________ John Andersen

As I mentioned, I have a static host name, from my ISP, based on the MACs. Even if my IP changes (a rare occurance), the host name never does, unless I make a hardware change. As a result, I have no need of dyndns.org. I simply rely on my ISPs DNS, when I want to connect to my home system. The only downside, is that the assigned host name is long and hard to remember. So, I've added "home" to my hosts file, with the current address, so that if I'm typing a command, I can use that name. My vpn is configured to use the fully qualified name from my ISP's DNS. I only use my vpn or ssh to access my system remotely.

Thanks for the insight in ADSL etc. Will see what I get. I have an independent ISP and will get the ADSL installed from the telephone company who is also in the business of promoting their own ISP. Outcome must be interesting and I may need your help in the future for my setup ;-).
