P2P Traffic Shaping For Home Use? 288

An anonymous reader writes "My housemate uses an aggressive P2P client, that when in use makes the Internet unusable for everyone else connected to the network. After hearing about various ISPs shaping traffic to reduce P2P traffic, I was wondering if there was a solution for managing P2P traffic on a home network. I have a Linksys WRT54G available for hacking. Can Slashdot recommend a way to reduce the impact of P2P on my network and make it usable again?"

      I have a Linksys wrt54g v8 and it has some good QoS options with the native firmware. You can restrict usage and bandwith by mac address, by the ethernet port your roomie's computer is connected to, or even the classic, by the tcp port. You can also set or deny different services depending on the time of day, and computer using them too.

        I love how people pimp their own client. But nearly every PTP client I've touched, has bandwidth limiting. Some of them, uTorrent included, allows you to schedule your bandwidth.

        The real problem here isn't traffic shaping, but about traffic courtesy. Your housemate may not know how much trouble their causing. Talk to them. Get them to set their max speeds to 1/2 or 1/4 of the available bandwidth.

        They may be surprised when their OWN web browsing gets better.

      To fix the annoyance, I would have to limit my bandwidth usage at some times of the day - and I wouldn't just have to limit my usage according to when the other tenants are awake, and according to when they use how much bandwidth, but also according to how much bandwidth my ISP feels like giving me today (my ISP is seriously bandwidth starved).

One of the problems with P2P is establishing many connections to flaky systems or networks. Your client (and router hold the connection open, waiting for response that never comes. That fills up the connection table and makes it hard to establish other, more productive ones.

      I had a housemate who ran P2P software all the time without even realizing it. Talking to him did nothing. Limiting the number of outbound packets from his computer to a certain number per second with a fairly high burst solved the problem. He liked playing WoW and when his WoW connection started getting all weird and I told him it was his P2P sofware he started to make sure it wasn't running. The average cap I set was plenty enough for WoW and enough for a decent download speed for P2P as well.

      I'm all for bandwidth throttling and traffic shaping as long as it's to ensure usage fairness. If I were running an ISP I would have a per-customer 5 minute bandwidth meter and customers who had exceeded their share for 5 minutes would have all their traffic dropped to the lowest priority until there was a 5 minute interval in which they hadn't exceeded their share.

      And it would be share of total pipe available to the ISP's upstreams, not some arbitrary fixed cap per customer. If the P2P application were written to favor connecting to other customers of the ISP that would be a way to avoid the re-prioritization completely.

      Setup is as easy as configuring a normal NAT device. Of course, if you want to play with port forwarding, that's there too, and if you want your QOS to be a little more sophisticated than the default (which you should really try and see if you're happy with it), there are a plethora of configuration options.

    You may be able to install DD-WRT [] on your router. It (along with other alternate firmwares) provides much better traffic shaping capabilities (called QoS for quality of service) than the default firmware. It lets you assign traffic to bulk (lowest), standard, express, premium, and exempt; based on port, MAC address, netmask (destination IP), or traffic type. Off the top of my head I believe the priorities refer to guaranteed 10%, 25%, 50%, 90%, and 100% of packets will get through.

    First step would be to find out what type of P2P he's using and (if it's not recognized by DD-WRT) what ports. Drop those down to bulk priority. Raise special activities like https web browsing to express (on the assumption that connecting to an https server means you're doing something important like accessing your bank). Stuff that's time-critical like VoIP and gaming should get premium priority. This took care of 90% of the problems I had.

    The remaining 10% proved extremely tricky. Newer bittorrent clients default to encryption on, and it was getting by the QoS. I tried tweaking all sorts of settings to mitigate this without success. What eventually worked was a setting anything on ports higher than 1024 to bulk priority, then specifying certain ports as having higher priority. This is the QoS equivalent of switching from allow all and blocking things you don't want, to deny all and allowing things you do want. That seems to have solved the bittorrent problem.

    The only problems that remain have to do with http and ftp transfers of large files. If someone sticks a 40 MB file on a web site, the router can't tell it apart from regular http traffic, so you can't drop its priority without also affecting regular web browsing. In one case a user was running a program to download an entire web site - that was killing the network since to the router it looked just like a lot of web browsing. Same with ftp - if you drop ftp's priority so the 100 MB transfers are bulk, the small ftp files like certain software updates are also bulk.

  • There are a bunch of options for open-source firmware that will do traffic-shaping on your router. I personally use Tomato [] for the AJAXy goodness and overall usability.

    You can do limits based on individual devices, which will keep any computer from ever saturating the network, or you can do time-based throttling, or whatever. I found the most useful setup was to make everything default to low priority and then raise the priority of HTTP, SSH, and other things I wanted to run interactively.

    I tried smoothwall, m0n0wall, IPCop, and pfsense before settling on pfsense. YMMV.

    From memory, I did a google search of slashdot and "traffi
  • Tomato (Score:2, Informative)

    Grab the Tomato firmware for your Linksys. Tomato's QoS features are much easier to configure than others like DDWRT. With Tomato, you don't need to be a Linux networking guru to do what you want. Tomato also handles P2P very well. You can pound a WRT54 running Tomato with heavy P2P traffic 24/7 for months with no perfmrance problems. No resets required. Grab it here []

    As someone mentioned in a previous post, it's much easier to just whitelist priorized services such as ssh, telnet or gaming protocols than wasting too much CPU cycles on detecting obscure P2P protocols with layer 7 filters.

    Personally, I use iptables & tc to setup a simple HTB (Hierarchical Token Bucket filter) system with 3 priority levels:

    - Interactive: SSH (with Minimize-Delay TOS-Flag), Telnet, Jabber, ...
    - Medium: HTTP, IMAP, SMTP, POP3, ...
    - Low: All the rest

    Shaping the upload speed is my only concern. All 3 classes may use the complete upload bandwidth. The interactive HTB class gets a guaranteed 90% of the bandwidth and a high burst value. The lowest HTB class has a burst of 0 and about 5% guaranteed upload speed.

    While this is only primitive setup, it allows lag-free ssh with an unlimited upload in the background.

    A short pragmatic example using HTB & SFQ can be found here: []

    Instead of cheaping out spend $30 a month for your own cable or DSL connection. Or, as many have suggested, just talk to the guy.

    Barring that just connect the 220v dryer line to the wall socket in his room and hope that he got his power bar for $5.99 at WalMart.

    Or even better please all of your room-mates and just move.
  • Tell him if he doesn't stop using P2P while everyone else is awake and using the net then you're going to cave his skull in with his monitor.

    You'll either make him stop or make him press charges. Either way it probably won't be an issue for you anymore.
  • Stay away from the third party "DD-WRT" firmware if you use any form of P2P. Due to some unresolved bugs in the firmware, any form of BitTorrent makes the router completely unresponsive, not even responding to the router's web interface.
  • I've a WRT54G with stock firmware in it. It has QoS in it from the factory. What's the problem here? What's with all this DD-WRT stuff? My default firmware is easy to use and works every time.
  • From the uTorrent FAQ []: "The default firmware for Linksys (and all replacement firmwares except for the latest DD-WRT and HyperWRT Thibor) have a severe problem where they track old connections for FIVE days, which causes the router to hang when using P2P apps, or any software that generates a lot of connections. DHT only aggravates the situation because of the number of connections it generates."

    Does NOT apply to WRT54G/GS v5 and up.

  • If he's not got a P2P client that lets him reduce its bandwidth use, get him to use one that does.

    Alternatively, insert a cheap PC with 2 LAN interfaces (NICs), running SmoothWall (firewall) between your ADSL modem & your switch.

    Among other things, SmoothWall can regulate bandwidth to guarantee each of you fair amounts.

    Actually, there OUGHT TO BE a ONE MORE FEATURE - yet to be developed? - in any such device:

    When one isn't using their portion of the bandwidth (& -certainly- when not connected to the
  • If you can't have a frank conversation about communal resource usage with your own roommate than your have much bigger problems than mere router configuration will ever solve.

    I'm sure you guys have laid down basic guidelines governing how you'll split up paying for and using shared stuff. Like, "Hey dude, if you insist on running that 20 node Beowulf cluster in your room to crunch SETI work units all day, you should pay more for electricity." Or if nothing that specific, at least rules along the lines of "neither of us should monopolize the common area on a consistent basis preventing the other from ever having guests over."

    I don't think shared Internet usage should be any different. If you're the administrator of the network at home, it seems that what you're suggesting would be tantamount to setting up bear traps in the common area to discourage over foraging by your inconsiderate roommate. Of course, if he/she is that much of a boor, maybe you have no choice.

    Bottom line though: it would probably be better to talk it over with your roommate rather than putting the smack down with filters and such... in the end, there'll be a lot less resentment from both ends.

  • The best piece of professional advice I ever received was this:

    "Don't use software to solve social problems"

    This seems pretty apt here - instead of spending money and time trying to do this the hard way....

    Just fucking smack him, and tell him to behave responsibly or lose his internet privileges.
