[Alug]Internet connection sharing
I have a redhat box here at home with no XWindows running. When I installed redhat it could pretty much automatically connect to my dialup internet connection through my Microsoft Internet Connection Sharing across my home LAN as soon as I plugged it into my hub, I don't know how it does this. I mainly use the box to ssh coonect to other linux shells across the internet. However, about 1 in 3 boots on the redhat box result in the message "Temporary failure in name resolution" when I attempt to ssh connect. The only way I've been able to find to get it to see the internet is to reboot it. Surely there' must be an easy way of showing it where the internet connection is without having to reboot! I would set up the internet dialup on the linux box and connect the three XP boxes in the house to it, but I only have a winmodem and as I'm hopefully getting broadband soon it's not really worth the hastle. While I mention broadband, a slightly off topic question. My local telphone exchange gets ADSL enabled on June 4th but in a couple of months a local company starts "trials" of WiFi internet access based on 802.11g with at least a 10 meg connection for around the same price as ADSL! Do you think I should go for ADSL or wait and risk connecting to the fast, but new service which could be unreliable? I'd like to get a short term ADSL contract until I see how the service pans out, but I can't afford the hardware for both as I want to use a router or an access point for my network, not an ADSL "modem" or Wireless Card. What do you think? Regards Ben Francis

I'd suggest checking the "gateway" and "DNS" settings in the Red Hat network configuration when this happens, and also when it works (though the fact that it's intermittent is puzzling -- but maybe the failure is an shortlived one somewhere between and inclusive of your Windows box and the outside world, and perhaps the reboot simply passes the time while this clears itself!).

Hmm! Where do you live, where will the WiFi hub be, and what do you think its range is likely to be? (Sorry to be asking questions rather than helping with your query -- which I can't, I'm afraid -- but I'm very interested in WiFi possibilities out here in deep Fenland ... ).

gateway and DNS settings? I'll have to get someone to talk me through this on IRC, perhaps on Monday.

A BIG FAT pipe is running between Peterborough and Nottingham which is being tapped off and coming from Peterborough to Stamford where wireless will begin . I went to a meeting the other week with the company who want to start the service, but it's still in the early stages. Their main focus is providing broadband (wideband) to rural areas, so you COULD be in with a chance depending on where you live and how far they're planning to take the service. Ben

Is that Invisible Networks? They are active in several areas of the country, including some of the bids in the EEDA (East of England Development Agency) competition for broadband projects. Google for the Demand Broadband website for more info. For more info re your original question, the forums on Broadband Norfolk http://www.broadbandnorfolk.co.uk may help, even if you're not in Norfolk. They are a knowledgable bunch over there. Plus ADSL Guide, previously mentioned in the thread. Syd

Answering my own message... maybe it's Peterborough-based X-Systems Management - just seen a story on The Register Also, Tiscali are making noises about rolling out a satellite system in the summer. The initial hardware costs have always put me off sat though. I can live with it only being one-way for a reasonable price. Syd

There is another company called spaceip who are looking at this kind of thing, currently they sell very expensive satellite solutions, but they are looking at doing things with 802.11(abg whatever else) in East Anglia.

The performance of dialup lines is bad enough without sharing them, and setting up a WinModem is a bit fraught even if there are drivers. I've just been through it with an Intel modem for which there are several sets of drivers out there, not all of which work. Particularly the ones on the Intel site!

What do you think? <<< If you're being offered the full 50MBit/s of 802.11g at the price of ADSL it sounds attractive. You're unlikely to use wireless for everything so you'll need a regular Ethernet router somewhere. If you get a standard one you can plug either a DSL or a wireless modem into it, but either of the latter could end up redundant if you later change to the other option. (I don't know what provider interface is needed for wireless so it could well continue to be useful.). A router such as the LinkSys EtherFast (available from Dabs) gives you 8 fast LAN ports, a fast WAN port, DHCP, NAT, remote admin, etc. etc. with a nice browser-based management interface, for less than £80. The only warning I'd make is that LinkSys don't support Linux (even though it's largely irrelevant what you connect to it), so don't mention the dreaded L-word if you ring for tech support.
Regarding 802.11g, I read recently that the standard isn't yet fixed and early adopters are warned that their equipment may end up incompatible. No idea how likely that may be. -- GT

Or, for £100, you could get the LinkSys wireless access point / router and be ready for whatever eventuality. I'd hang out for the wireless broadband. From my experience, ADSL is bottom of the league table very slightly above 56k modem, with wireless at the top followed by cable modem. Andrew. -- All views are my own .... who else would want them?

ooh, why didn't I think of that? Could I use that for both 802.11g wireless and a normal ADSL line? Now that IS a good idea... <<< Is that a 'g' device or just a 'b'? In any case it doesn't include an ADSL modem. How does a wireless service arrive at your house? If it's simply a local transmission point you only need wireless adapters in each of your machines; no need for a WAP of your own. If you have to retransmit you need something more than a regular access point, surely? -- GT

The one I have is with a 'b' [1], but there's one for the 'g' lot too [2]. You're right in that it doesn't include ADSL modem (just cable/dsl), but heck, I'm not encouraging people to sign up to the BT monopoly :-) [1] http://www.linksys.com/Products/product.asp?grid=33&scid=35&prid=415 [2] http://www.linksys.com/Products/product.asp?grid=33&scid=35&prid=508 Andrew. -- All views are my own .... who else would want them?

The signal will be transmitted from somewhere in my town, and with 4 computers in my house using the connection I don't wnat to be buying a wireless adapter for every machine if I can use my existing LAN. What I need is a device that: -Will connect my 4 computer LAN (2 XP, 1 XP/Linux dual boot and a Linux Box) to ADSL - Will also connect my LAN to a 802.11g WiFi internet service in the future That way I don't have to buy two lots of hardware. Anyone know of a device that can definately do all of these things and can be used with Linux?? Ben Francis

I did some Googling and came up with http://www.wirelessnewsfactor.com/perl/story/15096.html http://www.neoseeker.com/news/articles/headlines/Hardware/1502 My understanding is that a regular WiFi access point connects a group of machines, each with wireless adapters, to a regular Ethernet system. What you want is AAF, that is an Ethernet cluster with a shared wireless link. I'm fairly sure these exist, but not at the price level of the former. Perhaps you should consider using a Linux system as a bridge. Fit this with an 802.11g adapter so it can connect to the local access point, then set up masquerading to allow other machines beyond it to access the wireless network. This ought to be cheaper than buying a custom box to do the job. -- GT

I may well be mistaken because I hadn't even heard of 802.11g until a few weeks ago, but I thought that a device like the Linksys Wireless-G Broadband Router might do the job... The following is an extract from this page http://www.linksys.com/Products/product.asp?grid=33&scid=35&prid=508 "The Linksys Wireless-G Broadband Router is really three devices in one box. First, there's the Wireless Access Point, which lets you connect Wireless-G or Wireless-B devices to the network. There's also a built-in 4-port full-duplex 10/100 Switch to connect your wired-Ethernet devices. Connect four PCs directly, or daisy-chain out to more hubs and switches to create as big a network as you need. Finally, the Router function ties it all together and lets your whole network share a high-speed cable or DSL Internet connection." This product is close to the £100 mark which isn't TOO bad if it's going to save me having to buy two separate lots of hardware. Can anyone shed any light on whether this device really could do what I want...

...or whether I'm just misunderstanding it. Do I need any extra hardware as well, and are there any similar devices that could do the job for less money? Thanks Ben Francis

I'm not convinced. £100 routers are designed to be THE wireless hub on the system, which is fine when you just want to serve a few mobile devices or to avoid cabling. But they provide the infrastructure that chooses which channel to use and how fast to shovel the data down it, so I can't see how they'd work with another (bigger) one across the road trying to do the same job. I too may be wrong in all this, either because I'm missing something fundamental or because 802.11g is different to 'b' in some crucial way. But I have two WAPs and they've never seen each other, let alone set themselves up as network bridges. Least, there's nothing in either manual to suggest how to do it. And now I'll shut up and hope to hear from someone who really knows about the subject. It's a bit off-topic, after all. -- GT

Ben, if I've understood correctly, what is missing is an ADSL modem. Yes, you have what is needed to *share* the adsl connection across ethernet and/or wi-fi but you have to get it from the wall into your box first... and that requires another box of tricks as well as the router, switch and WAP. That's how I interpret the description you posted anyway. HTH Syd
