    For those of you that don't know, and are interested, Wondershaper can be found HERE [lartc.org].

    It is AMAZING.

    Sample config:

    DOWNLINK=6000
    UPLINK=200
    DEV=eth0

    # low priority source ports
    NOPRIOPORTSRC="6881 6882 6883 6884 6885 6886 6887 6888 6889 80"

    Sets those ports to only use up 200k of my 256k upstream leaving me the rest for SSH etc. I never have any problems w/my remote connection speeds this way. It's fantastic.

    I have only had a single problem, recently, with Debian unstable... It removed my libatm for some reason. I reinstalled that and all was well.

    Highly recommended for everyone, not just users of this "hackable" router.

      Yes traffic shaping is great, but is still not up to ensuring stable pings times for latency sensitive online games (e.g. Q3 + mods). The problem is the packet sizes. A large packet of typical MTU (1500) takes 10s of millseconds to be uploaded (on adsl - 256Kb/s), holding up higher priority traffic.

      Still, its much much better than not shaping :)

      Not quite, you're shaping your entire uplink to 200kb and not using the extra at all. To quote the wondershaper source:
      # shape everything at $UPLINK speed - this prevents huge queues in your
      # DSL modem which destroy latency:
      # main class

      tc class add dev $DEV parent 1: classid 1:1 cbq rate ${UPLINK}kbit \
      allot 1500 prio 5 bounded isolated


      Thats the class all uploads are shaped through. If you read the script all the other traffic classes are set with parent 1:1 which is the classid of the above. With tc you have to run all traffic through the available classes otherwise it gets 0kb rather than any remaining bandwidth, I accidently broke a netcafe once by forgetting to put DNS traffic into any class. Wondershaper does actually assign all traffic to 3 classes within the above, each with differing priority.

      The ports you mention are given lower priority but within that class, so within that bandwidth set in $UPLINK.
      • Bit lame replying to myself but while we're on the subject:

        You can mark packets from iptables rules and tc can read those marks and use them to classify traffic by using the mangle rules and --set-mark.

        Sounds simple but that gives you incredible power to setup QoS on linux routers. You can provide QoS on any of the filters iptables uses, so for instance you could use the layer 7 protocol filters (experimental) and limit traffic by protocol even if it's running over non-standard ports.

    Cisco only bought Linksys to prevent their routers from getting more advanced and competing with their expensive stuff.
    • There is a LOT of truth to this.

      Last month, my company was looking for a replacement for the overly expensive, hard to manage firewall. Our favorite consultants (who seem think we are idiots and yet don't understand the words "packet filtering") tried to sell us on a Cisco firewall device that was something like $2000. I thought this was insane, seeing as all we needed was a nice interface to ipchains (nobody but me knows Linux here, so that wasn't an option). I look at LinkSys, but they didn't have anything which would do anything more advanced than direct NAT. This seemed strange to me, as at home I had a Linksys firewall router that allowed me to do pretty much whatever I liked when it came to mapping ports and setting up load balancing.

      Dlink -- who used to be a direct competitor to Linksys in every segment of the market -- had an awesome device which rivalled the features of the Cisco router for only $300. I had a problem with the first one they sent out, got good support and they sent me a replacement. I had that one up and running in an afternoon without a problem (well, with one problem, but that was due to the Cisco cable router, not the Dlink). And we saved so much money, we could afford a nice spam filter and a new development server. And the new device has a nice, fairly unbuggy web interface that is way easier to use than plain ipchains/iptables with MOST of the functionality (it does bomb out after a certain number of NAT mappings, but since this thing is only 300 MHz I suppose that's for the best).

        The difference between the Cisco routers and the low-end DLink/NetGear are that the former are much more stable, and a lot of the routing logic is hardware based so they are able to scale & perform much better than the latter.

        I don't know why they would want to hold back Linksys development though, especially for things such as IPv6. They are a smart company, so I cannot figure out why they think holding back development of Linksys is going to advance their cause of spreading the use of IPv6.

        There are lots of people who use Linksys, but are not willing to spend a lot of extra cash just to get a Cisco box so they can do IPv6. And the more people that demand IPv6, the more ISPs are going to have to buy new Cisco hardware to upgrade their higher-end routers.
        • IMHO, widespread IPv6 adoption isn't going to come from customers forcing it on ISPs, it will come from ISPs forcing it on customers. IPv6 benefits the people in charge of managing really large networks, which isn't end users. Right now, ISPs can keep going using NAT, DHCP, and private networks to avoid switching over, but eventually they'll switch to IPv6 when the pain of the switchover is less than the pain of maintaining the system.
        • Lets not forget Linksys [linksys.com] is owned by Cisco these days. I hope they are not stupid enough to sell a router for $2000 under the cisco brand, but only $150 under Linksys.

          That's only true if you're not doing anything but routing. Start adding in any features that are remotely useful, and you've gone from CEF/fast switching to process switching. And that means you take a 5x to 10x performance hit.

          You actually have to purchase a *VERY* expensive Cisco to get one that can't be out-performed by even a relatively modest PC.

          And even on the high-end, there are PC's that will completely blow away any but the very largest offerings from Cisco.

          There are, of course, several real advantages to using a Cisco router instead of a PC. First and foremost, if you have the money for it, you're going to be able to find a network interface for almost any type of network you can imagine. DSL to SONET, the interfaces are there for the buying. I'd *almost* say that they would "just work", but that's not always the case. I just had to upgrade the IOS versio on one of my Ciscos (a *paid* upgrade) to get nothing but support for an additional ethernet WIC.

          Another large (perhaps HUGE) advantage is the fact that as long as you want to keep paying the money for it, there will always be someone there to back you up and make sure your problem gets resolved, even if you're not capable of fixing it yourself.

          So, I'm not saying that there's no use for Cisco. I'm just saying that absolute performance (and especially price-for-performance) are not real advantages for them.

          I don't know why they would want to hold back Linksys development though

          You can't? Let's think about it: Do you think they'd rather sell a $200 Linksys router, or a $2,000+ Cisco router?

          I know, it sounds cynical. Unfortunately, I've worked in enough corporations to know that is *exactly* how decisions are made on these things.

          They'll keep the Linksys line around for the low-end market, the home users that don't demand much. But for anything above that, they're never going to let Linksys compete with their Cisco line. They're not stupid.

    I currently own a BEFSR81 [linksys.com], which is their 8-port wired version (no wireless) that I purchased a couple of years ago.

    It's got built-in QoS, which can prioritize traffic. You can choose low or high priority based on either your IP port number, or one of the LAN ports (at least, the first four).

    I've tried it out, and it worked pretty well when I needed to slow down BitTorrent so that my dad could use his web browser and email (otherwise, BitTorrent was eating *all* of my bandwidth).

        There's no good reason to, however. These use lousy transmitters, and S/N goes way downhill as you boost power levels. Quadrupling the power could end up cutting your speeds in half at the expense of a bit more distance.

    Is there any way to improve Netgear routers? Their firmware pretty much sucks, and you can only manage it via thier browser-based tool (no telnet or tftp).

    Or is there just something inherently more hackable about that Linksys router?

    • Not true.

      I have a Netgear RT314, and it can be managed via telnet, no problems.
    • and you can only manage it via thier browser-based tool (no telnet or tftp).

      Totally untrue. I have or had 4 routers (RT311/314 and the MR314 and one other whose model# escapes me now) and they were all accessable via Telnet AND serial (nice since you don't have to reset the unit just in case you totally muck up the ip address). Now if by telnet you mean you can't just be plopped into a shell, then you're sorta right (though you do have access to the command line from the admin menu).
    • Netgear's support web site contains the source for some of their routers (eg the DG834 series [netgear.com]). Cool idea for people to be able to add their own features.

      I use a Netgear DG834G which appears to run linux 2.4.17 on its MIPS malta processor.

      You can download a bundle of the packages it uses from netgear but they are not configured so its
      hard to patch or hack with it cos you'd have to
      redo their work.

      This seems at odds with the GPL , on the grounds
      that if you use GPL'ed code you must publish not
      just the original source but your modifications as well . or am i wrong ?

      The firmware upgrade patch is easily dissasembled and i've managed to hack the file system (cramfs) out of the firmware . So there is a possiblilty
      that modifying the filesystem might open up safer
      modification by making telnet accessable. but i'm
      too much of a chicken to try it and i expect the

    It's really great to see people finally enhancing these boxes. These routers have ideal form factors compared to, say, a dedicated router PC running Linux, but their default firmware has always been very poor.

    I didn't see one feature mentioned that I'd really, really like to see added to these boxes: an IPv6 6to4 tunnel. This is an ideal way to penetrate a NAT so you can establish direct TCP connections (and speak UDP) to any servers on your LAN from the outside. IPv6 support has been in all of the major operating systems for some time now, including Windows XP, Linux and Mac OS X, and while not every application is IPv6 ready, the important ones (like SSH) already are.

    If 6to4 tunneling could be added to these consumer routers alongside IPv4 NAT, IPv6 stands to really take off without any help whatsoever from the ISPs. In fact, I almost prefer that my ISP not implement native IPv6. I like the fact that they now carry my encapsulated IPv6 packets without any ingress filtering, port blocking or other end-to-end-wrecking nonsense, and that they are oblivious to (much less control) the IPv6 address space. If or when the ISPs do implement native IPv6, you can bet that they'll exercise the same degree of arbitrary control that they now do over IPv4.

        There are two ways to link WRT54G's using the Sveasoft firmware. The simplest is to set one WRT54G to client mode and use the other WRT54G's IP address as the client mode gateway. This turns the WRT54G into a WET54G or WET11 equivalent.

        The second method is to use WDS and link two AP mode WRT54G's point-to-point.

For example, there are many old laptops that could incorporate newer hardware if only the firmware recognized it. I understand that the laptop manufacture wants you to buy a new laptop, but sometimes the only reason why a newer processor can't be used is because the firmware won't recognize it so it won't boot.

    • I think somebody needs to organize a development community around this. Creating a good stable version of Linux that can be easily installed onto the router. Of course this would require some sort of installer program, that could fetch updates & upgrade the firmware more easily too.

      Then it would be much easier to create all these advanced features, instead of having everyone adding their own single extra features, and never getting the exposure neccesary to stabilize the feature.

        We're trying to address some of these issues with openwrt [sf.net]. Openwrt provides a minimal firmware image with support for add-on packages via a writable filesystem; essentially a linux distro. The idea is two fold, it allows developers to focus on specific pieces rather than an entire firmware and end users to free up precious resources and customize the firmware by adding or removing features.

        Mesh routing is on the list of things to do with some progress being made in that direction already.

    I had a rather power hungry PC based wireless/3G/APRS/AX.25 router in my car for a while which I used to serve Internet at conventions and such. I recently replaced it with the WRT54G and the sveasoft firmware, which has several benefits:

    - The WRT54G only uses a few watts, whereas the PC based router spiked at 300W during startup and consumed north of 60W at idle and south of 100W during load. I also lost between 10-30% of the power due to conversion losses from the DC-AC-DC conversion through the auto inverter, since I couldn't find a good ATX power supply that ran on DC that I could couple to the car's batteries...

    - The WRT54G has dual antenna jacks that I don't need to buy delicate adapters or pigtails for. I couple them directly to the jacks on twin high gain 2.4GHz dipole magmounts on the roof of the car, which gives me way better reception than I was getting from the orinoco, a pigtail, and a single one of the same antennas.

    - Speaking of reception, kismet has been ported to the WRT54G! I don't need to screw around with the orinoco patches or hack my prism2 cards to add an antenna jack; it just works. I currently feed wifi data from the WRT54G to another computer which actually merges the GPS data with the wifi data from the WRT54G, because the WRT54G only has 4MB flash and 32K NVRAM for persistent storage, and you have to solder a USB serial chipset to the WRT54G PCB to add a serial port to it (for reading GPS's NMEA output); it doesn't come with one.

    - Now that sveasoft added dropbear to their latest firmware, you can ssh into the device and run wakeonlan to power up other devices on your network remotely. This is seriously cool shit; I park my car, it associates with my home AP in client mode and shows up on my home network. I can then ssh into the WRT54G to power up the other computers in the car using wakeonlan to transfer files to them (transfer rate is somewhere around 1 megabyte per second in my environment), start the car, use the TNC in the car's ham radio, etc. I had to turn off the PC based router I was using before because it would drain the deep cycle marine batteries I'm using to power the car computers in an hour or two at load, but now I can leave the WRT54G on for a few days before the batteries even get low.

    - If I forget where I parked my car, the antennas I'm using for the WRT54G are +6dBi, so I can pull out something with 802.11{b,g} and warwalk the parking lot looking for a strong signal from the WRT54G :)

    - It's only $80 brand new around here in the bay area, which is damn cheap for a low power 200MHz Linux box with 16MB of memory, FIVE ethernet jacks, your choice of DC or AC power, pretty lights, official vendor provided source code for the firmware, an active community hacking on it, and a 802.11g capable wifi chipset with diversity antennas in form factor half the size of the smallest mini-ITX machine you can possibly get. And they're on the used market for prices approaching numbers that make me want to say it's close to disposable pricing. Heh, disposable routers :)

    I have no access to the source code so how do I know whether or not this hacked upgrade monitors outgoing connections and passes interesting bits of information on to the author?

    Certainly I could sniff the wire and find out for sure but I don't have time for this!!! There's tremendous potential for a malicious third party to monitor traffic using this. It just makes me leery when there's no source code to preview. Even if there was, I don't have the time to review it!
