The setup is temporary and the primary purpose is to setup/upgrade my friend's computer via internet and transfer some big files from my computer. It is also a learning experience for a more permanent setup in the near future. I have borrowed some hardware. I also struggle a bit with the terminology. As always I'll put complementary information on the wiki. I have a D-Link Ethernet Broadband Router. A router is only a small box, and its fonctions are limited while a hub can be a whole computer serving as a dedicated server, right? No. See below. I have two cables. A short one, over a meter in length and a long one, 20+ meters. If I understand well, we have two kinds of cable (looking both at the link above and your email): 1- special 'Twisted Pair Crossover' cable/ cross-over ethernet lead 2- 'Cat 5' 'twisted pair' (UTP) cables / straight-through lead Both use the same RJ45 connectors. I am not sure about the UTP and Cat 5 bit: both have that written on them. Do that mean that they are not crossover cables? No. UTP is Unshielded Twisted Pair ie there is no overall braided screen around it, and pairs of wires are twisted together. CAT5 is an international standard for network wiring. Don't worry about either of them. Doing your test, this is what I notice: For the short cable, I see the same colored cables at the two ends, but the order is not the same: orange-blue-green-red vs green-blue-orange-red (actually the same but the other way round and with some transposition.) For the long cable, the order of the colors are the same at both ends. I would agree with you: the short wire is a cross-over, the long one is straight-through. For the sake of completeness, which part of the information written on the cable is relevant? The short one reads: E195773 (UL) CM 75oC EMC Cat 5E UTP 4 PAIR 24 AWG HYPER-PLUS PS-NEXT VERIFIED TO ISO/IEC 11801 004283M The long one reads: ENHANCED CABLE CAT.5E UTP TYPE CM 24AWG 75oC S.C.E. 114481 CMG ETL VERIFIED EIA/TIA-568A SHYARO CHI None of it. It all refers to the type of cable, not how it's connected. From all this, I don't know what conclusion to take. In the case of someone buying the stuff in a supply shop, what exactly should be written on the box, for both types of cables? Normal patch cables are straight-through. Cross-over cables should be clearly marked as such. Hmmm... again, what's the difference between a hub and a router (if any)? A hub is a very simple box that basically joins all the wires up together. (It's a bit more complex than that, of course.) So with four machines A,B,C and D on the network only one of them can talk at any one time. A switch is very similar to a hub, but allows simultaneous conversations to happen at the same time, so A can talk to B while C is talking to D. But you can still only have one machine on each port. Also called a switched hub. A router is an altogether more complex device that understands the protocols and decides where they need to go. So if one port leads to another network then the router only sends traffic out of that port if it needs to go there. In your case the traffic between your two machines would stay in your network, but both machines could talk to the Internet. Many broad-band routers have built-in firewalls. (A firewall filters the traffic going through it and only permits traffic that meets certain criteria. A good initial set-up is to allow all outgoing traffic, and no incoming traffic. That will not be sufficient if you need to run a mail server etc., and it stops some instant messanger functionality, but it is fairly safe.) Would my D-link box I mentionned qualify? Yes. It stands to logic that beside the adsl cable that would connect in the WAN slot of the router, I would need two length of straight-through cables. Not necessarily. A lot of switches and routers these days have logic in them that can correct a crossed-over cable. Check the manual. If so then you can use the cables that you have. From a quick browse on the D-Link website... If your router is a D-Link 502G then it would be better to use the cross-over cable between the computers. It only has one ethernet port and one USB port. Although you can use both to access the Internet it doesn't say that the two machines can talk to each other. All other routers mentioned on that site have at least four ethernet ports. I have just checked the 604's manual and it doesn't say that it handles cross-over cables. You could just try it and see, or an ethernet patch cable is cheap. Since this is a quick hack, I would prefer to use the router if possible. Using the cross-over cable between the machines means that you have to configure your machine to pass-through traffic to your friends machine. Webmin might make that easy, but

[newbie] home network Mandrake howto
Hello, I have not been able to find a simple step by step howto for home networking. So far, I have absolutely no experience in networking, or any IP address stuff. Right now, I have a friend's computer at home and I would like 1- to share the internet connection with my own computer's adsl. 2- be able to do file transfer from one computer to the other. To start with, I am not sure I have all the required hardware: I don't have a hub or (obviously) a dedicated server. My computer has two ethernet cards, one being connected to my adsl modem. My friend's computer also has an ethernet card. What I did is connect my second ethernet card to the second computer's card directly, with a cable running from one card to the other. I am not sure that's the proper way to do it... all the beautiful graphs I find on the internet picture little box, whatever it's called, that sits between the two computers. I don't have that and I don't know if it is possible to connect the two computers the way I did. Next, I tried to run the configuration wizard in MCC on both computers, on mine to share the internet connection, and on my friend computer to set a LAN connection, but so far no good. I am not sure what I am missing and I can't find a mandrake specific step by step howto. I created this page here: http://mandrake.vmlinuz.ca/bin/view/Main/HomeNetworking You can write your reply directly there, so that other can benefit from your answers, or to the list and I'll put everything there afterwards. thanks Augustin -- Linux.

Re: [newbie] @home and Mandrake
Hi, Try to find out your IP address and your netmask and nds adress under a working dhcp client (windblows etc.) then assign this to your nic under linux. This is working because your ip adres is assigned by dhcp but it is static ( my @home ipadres is still the same as 4 months ago when i started with @home). regards, manuel dopp -Oorspronkelijk bericht- Van: Pascal Poirier [EMAIL PROTECTED] Aan: [EMAIL PROTECTED] [EMAIL PROTECTED] Datum: dinsdag 16 januari 2001 3:34 Onderwerp: [newbie] @home and Mandrake Just asking a quick question for a friend that I am helping install mandrake.
