Well, I'm glad to have helped a little bit. Not sure I can help more, but I think you got good suggestions from other people. I think you have three choices: * Get another IP on the LAN and use a hub (or switch) to connect both machines to the gateway. Now that I've slept on it I'm quite certain a hub or switch will work -- a switch will work faster which is probably a mute point at this time (I don't think you'll need the speed in your two PC sub LAN), but if I could get a switch for only a nominal amount more than a hub I probably would, just for future expansion considerations. (A switch has one advantage / disadvantage in that it is harder to sniff all network traffic -- but you shouldn't normally need to sniff the traffic, and you certainly don't want anyone else to. Of course they can sniff upstream of your switch, this issue is not really a factor in the switch / hub decision.) * Let your Linux box serve as a (second) gateway for the Windows box -- I think this is essentially what Gerald Waugh (and somebody else) suggested. (This is almost the traditional share an internet connection approach, except you're sharing the LAN connection which *has* an internet connection.) * Finally, as Gerald also suggested, get an external box that is a router and hub -- I am not familiar with this approach or the hardware. Good luck, write back to the list with more questions, looks like there are lots of people willing to help. Randy Kramer Want to buy your Pack or Services from MandrakeSoft?

My ISP will win the prize for the worst tech support ever and they dont support WIN$ not to mention linux !! but here are the settings they gave me to set the DSL connection: my host name : hanan domain name: company.com gateway : 10.0.0.x 2 DNS IP's : and my static IP: 10.0.0.xx and thats about it SO where do I go from here ?? Hanan, I know you've received several replies to this, some contradictory, and you've now ordered another NIC. That's fine, AFAIK, but this is a confusing setup and possibly easier to handle than some have suggested (and possibly not) -- it depends on exactly what your ISP has setup. If your system is set up as I suspect, the second NIC will not help you and you eventually will need a hub (or switch -- more discussion below). If you want to experiment until you get the second NIC, consider setting up one computer at a time, and see if you can make them each work separately. Since the ISP is giving you a gateway address, I'm assuming he has something set up as a gateway. This is reinforced because the IP he has given you for the static IP is a private address (not on the public Internet). Thus the setup he is using is something like what I am using at home. I happen to own the gateway computer (at 192.168.0.10) and can set up up to 254 computers on my private LAN using addresses like 192.168.0.x -- they will all have access to the Internet (via the gateway) but they cannot act as servers to the Internet. (I think there are ways to do that, but I've never bothered). (The difference between your ISP's setup and mine is that I've chosen to use the private address range at 192.168.x.x, your ISP has chosen to use the (larger) range at 10.x.x.x.) If you can get each computer to work separately, then, IMHO, your best bet is to ask the ISP to assign you a second static address (in the 10.0.0.xx range) for the second computer. Then the last problem is to get both computers connected to the cable coming out of the wall. (At home I use coax, which means I can do this without a hub or switch. Yes, I'll use those terms in the same sentence, because in some cases they serve the same (or similar) purpose, and right now, my brain is not functioning well enough to decide whether this is one of those cases of not.) To be safe (because I haven't thought through whether a switch will do the job), I'd recommend a hub -- connect the RJ-45 from the wall and RJ-45s from each computer to peer ports on the hub (not uplink), in each case using a straight through cable, not a crossover (because the hub serves as a crossover). There is a chance that the RJ-45 supplied by the ISP is already a crossover, in which case you need to replace it with a non-crossover cable. (And, if I was thinking better, it's possible that you can use the crossover cable by connecting it to the uplink port.) I guess the reason I bring this all up is because I'm afraid that a second NIC will not solve your problem -- with the setup you've described so far, you are not quite in the traditional share an Internet connection scenario. You are behind a gateway, and the gateway is inherently sharing the Internet. It's also possible that you have two ISPs to deal with, so to speak. Surely, there is an ISP somewhere that is making the connection available to the Internet. It's possible that your landlord, separate from the ISP, has set up the gateway in your building, and, even if he's done it with permission of the ISP, not everyone at the ISP may understand the setup you are working under. Thus, for example, I don't know if your ISP needs to give you another static IP or you need to get it from your landlord. (You could even try a number at random, but there is a chance that you will pick a number used by someone else in your building and just create more problems (potentially in the future, if that person is not currently using their connection). Sorry if this seems a little disjointed, I'm rushing a little bit this morning, and am definitely not a networking expert. I do know how my home system works, and the (possible) analogy to your system seems obvious to me. If you have questions post again. Maybe someone else can understand what I'm trying to say and say it more clearly. Randy Kramer Want to buy your Pack or Services from MandrakeSoft? Go to http://www.mandrakestore.com

This is EXACTLY what's been mkaing me go in circles here, since I knew from the 10.0.0.x IP they gave me and from the fact that I just plug the rj45 to the wall which makes it obviously like an office environment == we in the building are on a LAN and the gateway ( which they say is running Linux by the way ) is giving us a way out to the internet !!

BOY it took me more than 15 msgs just to ask the correct question ... talk about newbies !! - Hanan AL-Shargi If it was me - yes i'd use two NICs. One to the building LAN / internet One to the other computer/s That way you can test each seperately. - ie you can get your linux box talking to the lan as client and to the other box as server/gateway. Set each systen up individually so they work then see if you can get the server passing through the net to the other box/s. By the way it is recommended to use different NICs so that it doesn't confuse linux. And a second NIC is cheaper than a hub or is it? Michael -- NT (as in Windows NT) is short for Nasty Technology.

[newbie] Do I need 2 NIC for connection sharing ?
Hi, I need some advise ( actually I'd rather specifuc steps :)) to get from Initial state below to Goal state ( also below ): Initial State: I have a 2 machines: First machine: a dual booting notebook ( LM 8.1 + Win98 SE) connected to DSL + printer. Second machine: a dual booting Desktop ( LM 7.2 + W2K ) both have NIC installed. Goal State: I need the first machine always running linux, the second one always running W2K, I want to connect them through a LAN ( bought a hub and some cables ) so that the second machine can connect to internet through the first one, and I need both machines to see each other's hard drives, and share the printer. DO I need 2 NIC's installed on the first machine to be able to do this ?( one to hold the LAN IP , one to hold the DSL IP ) All contributions welcomed :) - Hanan AL-Shargi Want to buy your Pack or Services from MandrakeSoft?

To share files between the two, SAMBA will be required. The first machine will be your gateway and probably the SAMBA server dns server etc. give them both addresses and names like Hanan1 192.168.0.1 Hanan2 192.168.0.2 Samba will set up pretty well with the wizard as will Internet sharing and Network. I have 4 connected to internet and sharing using a hub and it does work pretty good.

Dennis, you gussed it I have many questions, here is the starter: If I'm to set the NIC IP in the first machine to have 192.168.0.1 address , then where does the IP that I'm given by the ISP gonna go ?!? and I dont have a DSL modem, the building is prewired for DSL, there is a cable that comes out of the phone jack on the wall, and this cable's other end goes into my NIC card. My ISP will win the prize for the worst tech support ever and they dont support WIN$ not to mention linux !! but here are the settings they gave me to set the DSL connection: my host name : hanan domain name: company.com gateway : 10.0.0.x 2 DNS IP's : and my static IP: 10.0.0.xx and thats about it SO where do I go from here ?? - Hanan AL-Shargi Want to buy your Pack or Services from MandrakeSoft?

That is the one that you would plug into the wall jack. I Don't know if you need a cat 5 cable for that, but I believe you do, not just a phone chord. List help! Anyway, you canplug both computers into the hub. If you want the laptop as your interior LAN gateway then assign it 10.0.0.2 or whatever xx can represent on the windows box you will have to go to startdisplaynetwork and configure that at properties for the nic card in that computer. also assign it the address of 10.0.0.3 and the gateway as 10.0.0.2 for the first computer. Then the first computer will have the gateway as the 10.0.0.x that the service gave you. So you will have two computers hooked to the internet through the main one to an external server. In the DNS settings you will show the Hostname as company.com with the 2 DNS IP addresses as the connection. Did they give you a password and the type of authentication? If not may have to wing that and try different things. This is a start anyway, anyone with better instructions please jump in here. HTH Want to buy your Pack or Services from MandrakeSoft?

Re: [newbie] Do I need 2 NIC for connection sharing ?
Actually it is Category 5 (or 5E) Unshielded Twisted Pair cable. Cat 5 transfers at 10/100 mbs and Cat 5E transfers data at 1000 mbs. There are four sets of twisted pairs that are primarily there to help prevent radio frequency Interference. The ends of the four pairs get separated to make eight strands that get firmly inserted into the plastic RJ 45 8 pin connector. The RJ 45 connector is similar to the four pin RJ 11 telephone connector/plug. Thanks and have a great day : FWIW, that cable coming from his wall socket is an RJ45 cable (Ethernet : cat5). Its how they're wired. I've seen some installations happening : in office buildings * got 80 ft of cat5 free too*. : Want to buy your Pack or Services from MandrakeSoft?

Re: [newbie] Do I need 2 NIC for connection sharing ?
That is exactly how it should be done. BTW someone mentioned switches and hubs in the same sentence. They are two different things and should not be confused as being interchangable. A hub is just a device that allows connectivity between two or more PCs. This is a high collision device which means that packets collide during transmission across the LAN, etc. This reduces Data Transmission (without being to technical). A switch is an inteligent device that does not allow collisions and routes the signal Hope this helps and have a great day : I should leave the : cat5 cable coming from the wall where it is right now ( and then install : another NIC and hook the cat5 cable going out of it to one of the ports in the : hub. The cat5 cable coming out of the other PC's NIC should also go to another : port on the hub is that it ? : : - : Hanan AL-Shargi : : : : Want to buy your Pack or Services from MandrakeSoft? : Go to http://www.mandrakestore.com : Want to buy your Pack or Services from MandrakeSoft?
