As I see it you have two more or less simple options which would serve your purpose. 1. Buy a Broadband Router, with PPPoE capabilities. (Simple) 2. Set up your Linux as a router for your LAN. To do this you might need to buy another NIC, and you need to configure Linux. (Not that simple for me since I am a n00b on linux) Option 1: Both PC's will see eachother, and will receive an IP from the router, or you could specify IP (e.g 192.168.1.xxx) Option 2. The PCs will see eachother, since the Linux box will serve as a gateway for the walking Packard Bell. -- Kristian -- [EMAIL PROTECTED] mailing list
Re: [gentoo-user] Networking with ADSL?
Sorta-new-question here... my ISP is offering a wireless setup, and my mom prefers that because it will let us avoid drilling holes. The only setup I know for this is with an external router... some questions: - Are there any problems with wireless NICs and Linux? Will they be configured any differently from ordinary NICs, short of building new kernel modules? I am aware that many wireless routers have additional Ethernet ports, but I don't know exactly what I'm getting yet. - Is it possible to set up a PC as a wireless router? This is undesired, since I'll have to leave it on for the other computer to have a connection, but it might be what my ISP is offering. If so, are there any special Linux-related problems? Is the configuration any different? -- Tactless If it wasn't for fog, the world would run at a really crappy framerate. This is a .signature virus!

I'm afraid you can't connect a modem to a hub (in this circumstance) :) If your ADSL modem only has an ethernet port, your linux box will need two network cards. One to connect the PC to the hub, and one to connect the PC to the modem. If the modem has a USB port, and it's one of the (relatively few) ADSL modems with a Linux driver, you could connect it via USB and thus avoid the need for a second network card. To actually get the second PC on the internet, your Linux PC will need to have the following enabled in the kernel: Networking options --- IP: Netfilter Configuration --- Connection tracking [M] IP tables support [M] Full NAT [M] MASQUERADE target support [M] Your Linux machine needs the above options to perform NAT.. specifically IP masquerading. This allows both your PCs to have LAN IP addresses, (192.168.0.x), but both use the internet, (by having their IP address 'translated' into your ADSL IP address, and back). You may well also want some firewalling options, so enable at least: Networking options --- IP: Netfilter Configuration --- Packet filtering [M] All these can be staticly compiled instead of modules. You then need some way of enabling NAT, (and possibly firewall). There are some graphical firewall setup programs, but I think it's easier and faster to get it up and running with a simple pre-written script. I find this one satisfactory for home use: http://firewall.lutel.pl/ Simply fill in your various interface names, and specify what ports you want available to the internet and the LAN, then run it with ./firewall start.

We connected the dsl modem to the hub, and we could all connect at the same time. We would each get our own IP and everything. SNET sure did a good job setting up their network. Also, if we went to the webpage where it reports how many hours you used that month, the cgi script would often crash because we had more hours than there are in a month.

Unless your router has some clever programs installed on it, people will need to use active FTP to connect to your server, (ie. not passive ftp).

Will outside computers still be able to communicate directly with mine? How will they distinguish between them? I run a linsys here and it is a web interface to administer it. Under advanced settings there is a page for port forwarding. You can upen her up for FTP, SSH web server or what ever you like. The problem is, you'll need to use static IP's within your network to keep the FTP server enabled. This isn't a big hastle but requires you to RTFM. -- Regards, Ernie 100% Microsoft and Intel free -- [EMAIL PROTECTED] mailing list

Surely I'll want several machines using those at the same time... how will that work? Second point first... if you have several machines running a webserver on port 80, you'll have to choose a different port on your router to map to each. (one can use 80 of course). If you want each machine to be visible on port 80, either get separate IPs for each machine, (more expense/different ISP service), or combine them all into one webserver running virtual domains. Same with all other single port protocols, (SSH, IRC, Telnet, SMTP, etc.). FTP however, is different. Due to the age of FTP, it was designed with a different philosophy to single port networking approaches. When you connect to an FTP server, (on port 21 usually.. unless the server has chosen to use a different 'control' port), you speak plain text to it. Once you are ready to recieve a listing of files, you tell the server your IP, and a local port you have opened for it to connect to, (varies from connect to connect, but usually around the 32000+ range). The FTP server then connects to that port on your machine, and sends you data. This is Active mode FTP. Passive FTP, works in a similar way, but instead of you telling the server where it can stick it's data, the server will tell you to connect to it and will let you know what port. Again, this is a dynamic port and usually a FTP server will have a specific range that it will use. So, if your ftp server allows you to specify the range of ports it can use for passive ftp, then you should be able to tell your router to forward that range of ports to your FTP server machine, thereby enabling passive FTP. This is advantageous for people trying to connect to your server, who are also behind a NAT gateway, (as your server won't be able to connect to their machine for the same reason... thus the need for passive FTP). Sorry I'm being so annoying... I hate it when I do something with my computer that I don't understand 100%. Ditto :) Hope that explains it enough for you. MAL -- [EMAIL PROTECTED] mailing list

Same with all other single port protocols, (SSH, IRC, Telnet, SMTP, etc.). FTP however, is different. Makes sense. So what I'm looking at is making it seem to the outside world like I'm running just one PC (and I certainly wouldn't have two daemons running on the same port on one PC). Due to the age of FTP, it was designed with a different philosophy to single port networking approaches. When you connect to an FTP server, (on port 21 usually.. unless the server has chosen to use a different 'control' port), you speak plain text to it.

Again, this is a dynamic port and usually a FTP server will have a specific range that it will use. That explains a lot of problems I had with my old ISPs. We didn't get external IPs back then, so we had to use passive FTP (as clients). So, if your ftp server allows you to specify the range of ports it can use for passive ftp, then you should be able to tell your router to forward that range of ports to your FTP server machine, thereby enabling passive FTP. I don't think that would be much of a problem. Worst case, I can run my machine on DMZ (de-militarized zone), so it gets all of the ports. Hope that explains it enough for you. Sure does.
