Initially I got things working with the Technicolor TG582N as supplied by the ISP, but it appears quite horrible in most of its functionality. I find most cheap domestic broadband routers are, to be honest. Little plastic blobs with the absolute minimum spec of hardware, configured via web interfaces that can politely be described as clunky, and packing many unwanted features.
With FTTC here in the UK you have a separate NTE box supplied by British Telecom and then you supply (or your ISP supplies) a router that connects to that by Ethernet and talks PPP-over-Ethernet to your ISP. So, anything that can do PPPoE works as the router, no special hardware required. Any Linux box will do.
I had this Soekris net4801 box that I purchased in 2005, been running it constantly ever since, and it still works fine. It’s a nice little thing; 266MHz fanless CPU, 128MiB RAM, three 10/100 Ethernet ports and CompactFlash for storage. Draws under 10W when idle and not a lot more at full tilt.
Really quite expensive though. After delivery charges, purchase of compatible PSU and CF card and currency conversions are done you’re probably talking £200 now and I seem to recall it was similar back in 2005 too.
I upgraded that from Debian etch to lenny to squeeze to wheezy — which went remarkably without incident by the way, a testament to Debian’s excellent upgrade procedure — and set it to work as the router. Since it’s just a relatively conventional Debian install it’s really easy to configure PPPoE, IPv4, NAT, IPv6, firewalling and anything else.
There’s a couple of things I’m not too happy about though.
What if it dies? ^
If you have a Soekris last several years then it’s going to be pretty reliable. There’s no moving parts, the most likely faults are going to be the CF card or the power supply. Even so, this one’s been in service about 8 years and that’s a really good innings. It could go any time and then what will I replace it with?
Of course I still have the Technicolor and that will work well enough to get connectivity until I put something better in its place again, but what would be that better thing?
Back in 2005 I had a bit more disposable income than I do now and £200 was okay to spend on something I was interested in playing with. I’m done playing with it now though and spending £200 to end up with a Linux box that runs at 266MHz and has 128M RAM is going to hurt. Also the net4801 is end of life so will get harder and harder to purchase new, and any replacement will cost a little more.
Is the Soekris really beefy enough? ^
Right now I only have 40M down, 10M up FTTC and the Soekris doesn’t appear to be limiting that any more than the Technicolor limited it.
Conceivably though I may one day upgrade it to 80/20 or more and that is starting to push the limits of a 100M Ethernet port, let alone a 266MHz CPU.
As you would expect from a 266MHz CPU with 128M RAM it’s dog slow at doing anything much in user land. This is a pretty minor gripe as the use case here is that of an appliance, like the broadband router it replaced. You shouldn’t really need to touch it much. Something slightly less puny would be a nice bonus though.
HP Microserver ^
HP have been doing cash back deals on their Microserver range for a few years now. I already have one here at home being a file server and a few other bits and pieces. If they were still doing the cash back then I’d strongly consider buying another one to use for this.
It would draw a fair bit more power than the Soekris does, but they are still quite efficient machines and I would probably find it more things to do since it would be a lot more capable.
Without the cash back though I don’t think it can be justified. Retail price of a Microserver at the moment is around £265+VAT.
Update: It appears the cash back offer has returned, at least for September 2013!
It’s a contender, but it will leave me with some cheap nasty hardware running a non-standard Linux distribution on an ARM CPU. I’m sure OpenWrt is great but I don’t know it, I’d have to learn it just for this, and it’s not likely to be useful knowledge for anything else.
If possible I want to remain running Debian.
This would certainly work; a Cisco off of ebay may be cheap enough, otherwise a new Mikrotik Routerboard would be within budget. Say an RB450G.
The main issue again would be it’s not Linux. That’s not necessarily a bad thing, it’s just that it wouldn’t feel familiar to me. I know how to configure everything in Linux.
Something from Fabiatech ^
Looks good. £289+VAT though.
omg!! Raspberry Pi everywareeeeeeeeeeeeeeeeeee!!!!! ^
Yeah, Raspberry Pis are nice pieces of kit for what they are designed for. Which is not passing large amounts of network traffic. They only have one 100M Ethernet, and it’s driven by USB 2.0 so it’s going to suck. It will suck even more when you attach a USB hub and more USB Ethernets.
Something from Jetway ^
Alex suggested looking at these devices. They look quite fun.
A bare bones system that on paper should do the job (1.6GHz Intel Cedar Trail CPU, two Realtek gigabit Ethernet, one SO-DIMM slot for up to 4GB RAM) seems to be £149+VAT.
There seems to be a good selection of other main boards and daughter boards if that config wasn’t suitable.
Anyone got any personal experience of this hardware?
This Is Not An Exit ^
I still don’t know what I will do. I might put off the decision until the Soekris releases its magic blue smoke. I would be interested to hear any suggestions that I haven’t thought of.
Here are the requirements:
- Capable of running a mainstream Linux distribution in a supportable fashion without much hacking around.
- Has at least two gigabit Ethernet ports.
- Is beefier than a 266MHz Geode CPU with 128M RAM
- Easy to run its storage from an inexpensive yet reasonably reliable medium like CompactFlash or SD/microSD. Write endurance doesn’t really matter. I will mount it read-only if necessary.
- At least one serial port so I can manage it from another computer when its network is down, without having to attach a VGA monitor and keyboard. The Soekris manages this perfectly, because it’s what it’s designed for. It doesn’t even have a VGA port.
- Total configuration of the BIOS from the serial port, so a VGA monitor and keyboard are never necessary. Again, that’s how Soekris products work.
- Ethernet chipsets that are actually any good, i.e. not Realtek or Broadcom.
- Capable of being PXE booted so that I don’t have to put the storage into another machine to write the operating system onto it.
