AboutµTorrent

µTorrent isaBitTorrentclientoriginallycreatedbyLudvigStrigeus(ludde), and is currently maintained by a team of developers atBitTorrent,Inc.Aclientisacomputerprogramthatfollowstherulesofaprotocol. For example, HTTP (HyperText Transfer Protocol) is theprotocol used for transferring web pages and other content, and yourHTTPclient(orwebbrowser) is theprogramyouusetoget thosewebpages. Some popular browsers include Microsoft Internet Explorer,MozillaFirefox,Opera,andAppleSafari.Toanextent, theyallwork inthesamewaybecausetheyfollowthesamesetofrules.Justasthereare multiple HTTP clients, there are multiple BitTorrent clients thatobserve and conform to guidelines set in the BitTorrent protocoldefinition,andµTorrentisonesuchBitTorrentclient.

SowhatsetsµTorrentapartfromotherBitTorrentclients?

Micro-Sized Yet Feature Filled: Most of the features present inotherBitTorrentclientsarepresentinµTorrent, includingbandwidthprioritization,scheduling,RSSauto-downloadingandMainlineDHT(compatible with BitComet). Additionally, µTorrent supports theProtocolEncryptionjointspecificationandpeerexchange.

Resource-Friendly: µTorrent was written with efficiency in mind.UnlikemanyotherBitTorrentclients,itdoesnothogvaluablesystemresources,allowingyoutousethecomputerasifitweren'tthereatall.Additionally,theprogramitself isveryportable,beingcontainedwithinasingleexecutablesmallinfilesize.

SkinnableandLocalized:Variousicon,toolbargraphicandstatusicon replacements are available, and creating your own is verysimple. µTorrent also has support for localization, and with alanguage file present, will automatically switch to your systemlanguage.

TheBasicsofBitTorrent

BitTorrent (often abbreviated as BT) is a peer-to-peer (P2P)protocol(adescriptionandsetofrulesonhowtodothings)createdbyBramCohen,designedtodistributedatainsuchawaythattheoriginaldistributorwouldbeable todecreasebandwidthusagewhilestillbeingabletoreachat leastthesameamountofpeople.Cohen'sideawasto"break"thefilebeingtransferredintosmallersegmentscalledpieces.Tosavebandwidth,eachpersondownloading(morecommonlyreferredtoaspeers in theBitTorrentcommunity)wouldhave thepieces that theyacquired available for upload to other peers in the swarm (the entirenetworkofpeopleconnectedtoasingletorrent).Inthisway,muchoftheloadof sharing the file toeverypeer interested in it isoffloaded to thepeers.Notethataseedisbasicallyapeerwitheverypiece,sowhenapeer successfully attains all data in the torrent contents, that peerbecomesaseedaswell.

While on the surface, it appears that the only way to maintain aswarm'shealthisfortheretoalwaysbeaseedconnectedtotheswarm,thatisnotthecase.Themostimportantfactortodeterminingwhetheraswarm can continue to allow peers to complete a torrent is theavailability. The availability of a torrent is the number of completecopies of the torrent contents there are distributed in the part of theswarmyou'reconnectedto,includingthedatayouhave.Inmostcases,ifthereisanavailabilityof1.0orgreater,thenevenifonesinglepersondoesnothaveallthepieces,theyareallstilldistributedacrosstheentireswarmandcanbeacquiredtoformthecompletefile.

Inorderforeveryonetobeabletolocateoneanother,thereneedstobesomecentralized location thatpeerscouldconnect to inorder toobtain theotherpeers' IPaddresses.BitTorrent trackers serve as thiscentralized location. In the most basic explanation, for each givenswarm, a tracker only needs to collect a peer's IP address and portnumbertosharewithotherpeersconnectingtothatsameswarm.

BecauseoftheverynatureofBitTorrent,speedsarenotguaranteed

«Previous Next»

for any given torrent swarm.While you may get great speeds in oneswarm,youmightnotinanother.ThisisduetothefactthatBitTorrentisaP2Pprotocol,so itdependsontheuploadspeedsof theotherpeersyou are connected to to generate your download speeds. A commonmisconceptionheldbymanypeople is that torrentswarms thatcontainmoreseedsandpeersarefasterthanthosewithless.Thisisnotalwaysthecase.Therecanbeaswarmwithonlyafewseedsand/orpeersonfast Internet connections, and you'll be able to get great speeds fromthem,whileaswarmwithmanymoreseedsand/orpeersmightcontainmostlypeoplewithslow,dial-upInternetconnections,willgetyouterriblespeeds from them. In thesamevein,connecting tomoreseedsand/orpeers does not equate to greater speeds, and seeds don't necessarilygivebetterspeedsthannormalpeers.


SetupGuide

ThefocusofthissectionistohelpyouconfigureµTorrenttobeableto obtain the optimal speeds for your Internet connection. Whileconfiguringitproperlydoesnotguaranteethatyouwillhityourmaximumuploadand/ordownloadspeeds,itguaranteesthatµTorrentisdoingthebestitcantogetgoodspeeds.BesuretoreadthisentiresectionifyouareunfamiliarwithconfiguringµTorrent,becauseyouwillbeexpectedtohavereaditalreadywhenaskingforhelpelsewhere.

TheSetupGuideWhenyouopenµTorrent for the first time, youarepresentedwith

theµTorrentSetupGuide.Asstated in thewizard, following thesimpledirections will help you select the optimal settings for your Internetconnection.

Inthefirstpart,youareaskedtoselectyouruploadspeedfromthedropdownmenu. Ifyoudonotknowthis information,youcan testyourInternet connectionspeedbyselectinga locationclosest towhereyouaresituated,andclickthe"Runtests"buttonatthebottomofthedialog.Whenyouarerunningthespeedtest,makesureyouarenotusingyourInternetconnectionforanythingbesidesthetest. Ifyouhaveanyothercomputer on your network, disconnect them or shut them off beforerunningthetest.Runthetestseveraltimes,andtaketheaverageofyourupload speed given in the tests. After the speed test, µTorrent willautomatically attempt to configure the settings based on the results ofthe test. Ifyouwish,youcanmanuallyselectyourconnection'suploadrate from the dropdown menu, but do note the fact that there is adistinctionbetweenbitsandbytes,andspeedresultsaregenerallygiveninkbps (kilobits per second),which shouldnot be confusedwithKiB/s(kibibitspersecond).Additionally, the testsmaynotbe100%accuratedue to factorsoutsideof yourcontrol, so if theclosestoption isonlyalittlebithigherthanwhatyoureceivedonthetests(perhapsby10%),it'sgenerallysafetoselectthat.Ifthedifferenceisgreaterthanthat,it'sbest

toselecttheloweroptionandmanuallysetthecorrectuploadspeed.Donot be tempted to select an optionmuch higher than indicated on thespeedtests inhopesthat itwillhelpyoudownloadfaster,as itwillnot,andmightendbeingdetrimentaltoyourspeedsinstead.

Inthesecondpart,aportisrandomlyselectedforyouthefirsttimethe SetupGuide is displayed, though you are free to change the portused. Alternatively, setting the port to0 indicates to µTorrent that youwouldlikeforittoselectarandomportafterthechangesareconfirmed.Afteryouselectyourport, left-click "Runtests"tocheckthattheportisopen.ItisessentialthataportisopenforµTorrenttolistenforincomingconnections on. If you are having trouble opening a port, continuereadingontotheportforwardingguide.

When you finish configuring everything, left-click "Save & Close"and you're done! If, for whatever reason, you need to return to thiswizardtomakeachange,you'llfinditaccessiblebyselecting"Options"then"SetupGuide..." (or press Ctrl + G ) in µTorrent. Alternatively, youcan left-click onthenetworkstatusiconinthestatusbar.

CorrectingSomeSettingsIfyoumanuallychoseaconnectionuploadrateandfoundthatyou

had to round down when selecting your connection type in the SetupGuide, youshouldadjust youruploadspeed limit to takeadvantageofthe extra upload speed you actually have. Take the average uploadspeedyoureceivedwhentakingthetestanddivideitby10,thenroundittotheclosestwholenumber.Nowusethiscalculatednumberasyourglobalmaximumuploadrate.

TestingYourConfigurationBecausetorrentsdon'tnecessarilyguaranteespeeds,youcan'tjust

pick any random torrent and expect to be able to test the speedsproperly. Luckily, there are many torrents out there that are seededperpetually by computers sitting on fast broadband connections. Try atesttorrenttotestyourconfiguration!

«Previous Next»

When properly configured, µTorrent should be able to attain themaximum speed possible for most common consumer Internetconnections with these test torrents without much difficulty. Becausethese torrentsaresimplyused for testingyourconnectionspeeds, it issafe todelete themwheneveryouare finished testing.Remember thatthese speeds are not indicative of how fast every torrent you comeacrosswilldownload.

ISPInterferenceSome Internet Service Providers (ISP) block or throttle BitTorrent

connectionsbecauseofthehighbandwidthitgeneratesduetothesheernumber of people using BitTorrent. Protocol Encryption combats thisattack vector by hiding the fact that connections are BitTorrentconnections. Some ISPs cannot distinguish an encrypted connectionfromanyotherrandomdataconnection,sotheyareunabletolabelitasaBitTorrentconnection,andconsequently,cannotblockorthrottleit forbeingaBitTorrent connection. Ingeneral, there isnoharm inenablingProtocol Encryption, other than a marginal increase in peercommunicationoverhead.

Take note that some ISPs are starting to identify even encryptedBitTorrent connections with upgraded hardware, so even ProtocolEncryptionmightnothelpusersgettingthrottledbytheirISPs.Foralistof ISPsknown to throttle,check theBadISPs listonVuzeWiki. If yourISPisknowntothrottleorblockBitTorrenttraffic,thenyoumaywanttoconsidersettingtheencryptionto"Forced"anddisablelegacyincomingconnections.Ifthatfails,thenthesolutionwouldprobablybetoswitchtoanISPthatdoesnotthrottleorblock.


PortForwarding

Alargeportionofthetime,userscomplainthattheyarenotgettinggreat speedswithµTorrent.This can sometimesbeaproblemwithanindividual torrent (a lack of quality seeds, for example), but it is alsopossiblethattheuserisnotallowingincomingconnectionstoreachhiscomputer, and thus, is not making optimal use of µTorrent's ability toconnecttopeerswiththattorrent.SinceµTorrentworksbestwhenitcanconnectfreelytootherpeers,blockedorreducedaccesstootherpeerswilladverselyaffectthedownloadspeedsausercanexpecttoachieve.

Beingunabletoacceptincomingconnectionsmeansyourcomputeris in a firewalled state. In µTorrent, if you are unable to get a greennetworkstatusiconafteralongperiodoftransferringdifferenttorrents,itisanindicationthatyoumightbeinafirewalledstate.

WhyBeingFirewalledisBadManyfirewalledusersfindthemselvesthinking"Hey,I'mfirewalled,

butIcanstilltransferthefiles,soitmustmeanI'mokay!"Whattheyfailtorealizeisthatbeingfirewalleddoesnotnecessarilymeanyoucannotdownloadatall,asfirewalleduserscanstillmakeoutgoingconnections,connectingtopeerstotransferdatainthatway.Whilethisistrue,that'sallyouarelimitedto.Thatmeansthatifsomeoneelsetriestoinitiateaconnectionwithyou,theattemptisblockedbyyourfirewall.

Youmustthenrealizethatyoumightnotbetheonlyfirewalleduserin the swarm. Since firewalled users can only make outgoingconnections,andcannotaccept incomingconnections, it isnatural thatthey (the firewalled users) cannot connect to each other. Being in afirewalled state not only cuts into the potential speed you could beattainingwhennotfirewalled,butalsomeansyouareofverylimitedusetootherpeersintheswarm.Becausetherearelesspeopleavailableforfirewalled users to connect to, they are open to less sources for data.Additionally, because they cannot accept incoming connections, other

peers do not connect to them, so they lose even more attention.Essentially,peerswhoarenotinafirewalledstatehavethepotentialtoconnecttomanymoresourcesofdata.

Removingyourself frombeing ina firewalledstatedoesnotmeanyouhavetogetridofyourfirewallentirely.Theonlyrequirementisthatyouallow theapplicationyouwish tobeunfirewalled in to listen to theporttheywanttothroughthefirewall,alsoknownasportforwarding.InthecaseofµTorrent, youneed to set your firewall toallowµTorrent tolistentotheportsetintheconnectionpreferences.

Although itmaysound likeasecurity risk to "poke"ahole in yourfirewall,itisnotthecase.Ifnoapplicationislisteningontheportthatisopened in your firewall, any incoming connections on that port will beignored. If an application is listening, security is up to that application.Unless there is a known, fully-remote exploit for the current version ofµTorrentthatwouldbreakyourcomputer'ssecuritysetup,thereisnoriskinopeningaportonyourfirewallforµTorrent.

ForwardingPortsinYourSoftwarePersonalFirewall

Nowadays, it is not uncommon for people to have a softwarepersonalfirewallinstalledontheircomputers.WhilemanypeoplesimplyallowapplicationstheyrecognizetoaccesstheInternet,oftentimes,itisnot enough, as the firewall may continue to block the port that theallowedapplication is trying to listenon.Assuch,specific firewall rulesmayneedtobecreatedinorderforµTorrenttoworkonacomputerwitha software personal firewall installed. The general rule of thumb youshould follow is that you have to allow incoming TCP and UDPconnectionsthroughthelisteningportsetintheconnectionpreferences.Because you are forwarding a specific port in your firewall, it isimperative that you do not have µTorrent randomize the listening porteachtimeitstarts.

Becauseofthewidevarietyofsoftwarepersonalfirewallsavailabletoday, there isnowayto includespecific instructionsforeveryproduct.

Though this is thecase, there isonespecific firewall thatµTorrentcancreateafirewallruleforautomatically,andthatistheWindowsFirewall.TherelevantoptionassumesyouarerunningWindowsXPwithatleastServicePack2(SP2)installedornewer,andhavethefirewallenabled.

ForwardingPortsinYourRouterWith broadband becoming the prevalent way by which people

access the Internet,andmultiplecomputers ineachhomebecomingacommonsight,routersareoftenusedtosharethebroadbandconnectionacross the computer network in the home. Even if multiple computersare not being used on the broadband connection, ISPs often supplyroutersfortheircustomerstouse.Whatmanypeopledon'trealizeisthatrouters themselves act like a firewall that, when left unconfigured, willgenerallyleaveyourcomputerfirewalled,evenifyouhaveyoursoftwarefirewallconfiguredproperly.

UniversalPlugandPlayandNATPortMappingProtocolAs with software personal firewalls, there are a wide variety of

routersavailable,andbecauseof thesheernumber, it is impossible toinclude port forwarding instructions for each router model in this usermanual. Fortunately many routers support Universal Plug and Play(UPnP) or theNAT Port Mapping Protocol (NAT-PMP), which allowµTorrent to open a port on the router automatically without userintervention,thenclosetheportwhentheport isdonebeingused.Theproblemwith thesezero-configurationprotocols forautomatically tellingrouterstoforwardportsisthattheymaynotbesupportedbyallrouters,and different/incompatible implementations of the protocols may beincludedinmanyrouters.Bydefault,UPnPandNAT-PMPareenabledinµTorrent. If you find that youarestill ina firewalledstate, then it likelymeans your router does not support either protocol, or includes animplementationincompatiblewiththeimplementationusedbyµTorrent.Ifthisisthecase,thenitisrecommendedthatyoudisablethesefeaturesinµTorrent,setupastaticIP,andforwardyourportsmanually.

SettingUpaStaticIPOnmostrouters,aconnectedcomputer'sIPaddressonthenetwork

ispickedfromapoolofIPaddressesavailablefortheroutertochoosefrom through Dynamic Host Configuration Protocol (DHCP). Thekeyword here is "dynamic," as this indicates that each computer's IPaddress is assigned on-the-fly based on what IP addresses are stillavailableintherouter'spoolofusableIPaddresses.WhilesomepeoplegetluckyandkeeptheirLANIPaddressesforalongperiodoftime,thatis not a guarantee under DHCP. As such, port forwarding rulesmightwork one day in forwarding traffic through a specific port to a specificcomputeratitsLANIPaddressatthetimethattherulewasmade,butitmayceasetoworkonanotherdaybecausethatspecificcomputer'sLANIP address may have changed along the way. Some routers (notably,Linksysrouters)don'tevenbothertoforwardportstocomputerswhoseLAN IP addresses are within the DHCP IP range. Because of thesereasons, it is necessary that you set up a static IP address for yourcomputer (preferrably,outsideof theDHCPrange)beforeyoucontinuewithforwardingyourportsmanuallyontherouter.

DownloadingWithµTorrent

SimilartoneedingaURL,likehttp://www.utorrent.com,togoto awebsite anddownload content, either a .torrent file or aMagnetlinkisrequiredtodownloadcontentavailablethroughBitTorrent.Mostofthetime,youcandownloadthisfilefromawebsite,thoughyoucanalsoget it froma friendorsomeother formof transfer.Manywebsitesoffer.torrent filesasonemethodofdownloading filesavailable through thatwebsite.Sitesthatcontain.torrentfilesaregenerallyrepositoriesofonlythe.torrentfiles,andusuallydon'tcreateordirectlymakeavailableanyof the content being shared.

import it into µTorrent. There are several ways of achieving this inµTorrent:

Double-click the.torrentfileortheMagnetlink(onlyif.torrentfilesareassociatedwithµTorrent)Drag-and-drop the.torrentfileintoµTorrentSelect"File" then"AddTorrent" (orpress Ctrl + O ) inµTorrentandopenthe.torrentfileIf youknow thedirectURL to the .torrent file, butdon't have it onyourharddrive,youcanselect"File" then"AddTorrent fromURL"

«Previous Next»

(orpress Ctrl + U )inµTorrentandentertheURLofthe.torrentfile

After opening the .torrent file, tell µTorrent where you'd like thetorrent contents to be saved. If µTorrent doesn't automatically startdownloading, you can start the torrent job manually by selecting thetorrent job in the list and pressing the "Start" button on the µTorrenttoolbar,orby right-click ing the torrentandselecting "Start". If youareusingaMagnet link,youwillneed towaita fewseconds for theMeta-datatoberetrieved.

Afteratorrentjobfinishesdownloading,youmayviewthefilesthatyouhavedownloaded.Whileyoucanalso remove the torrent job fromthetorrentjobslistifyousowish,youarehighlyencouragedtoleavethetorrent job seeding (uploading after you have obtained every piece).Although the lengthof time that you should leave the it seeding is notdefinedinparticular, it isrecommendedthatyoushareuntiltheamountofdatayouuploadreachesatleastthesameastheamountofdatathatyouhavedownload, also knownas reachinga1.0ratio. This ratio iscalculated by dividing the amount of data you have uploaded by theamountthatyouhavedownloaded.Granted, it is technically impossiblefor every person in any given swarm to reach a1.0 ratio, but peoplewholeavetheswarmbeforeevengettingclosetothatratioareabhorredintheBitTorrentcommunity,andarelabeledasleechers(whichcarriesa strong negative connotation). Because leechers have a detrimentaleffect on swarms, some people resort to vigilante tactics and blockconnectionstoleechers.Additionally,privatetrackersmaybanleechers.

Even after having carefully and laboriously followed all the portforwarding instructions previously written, you've found that your portsimplyrefusestoopenup.Sowhatexactlyistheproblem?Possibilitiesinclude(butarenotlimitedto):

IntentionalISPinterference:SomeISPsareknowntosimplyblockconnections to unauthorized ports, in which case your entirenetworkisessentiallyplacedintoafirewalledstate.

Internetconnectiontype:Oneprominentexampleofthisbeingthesource of the problem are Internet connections that are receivedwirelessly (though satellite or something similar). Customers ofwireless connections are very often not givenWAN IP addresses,and so are permanently in a firewalled state. In fact, any kind ofconnection where you are not in control of the NATwill generallyleaveyouinanunfirewalledstate.Suchisthecasewithuniversity-providedconnections,wherenetworkadministratorsgenerallyblockconnectionstounauthorizedports.

Even then, though, being behind aproxy essentially places one behind a firewall, so you might stillsufferproblemsasifyouwerebehindafirewall.

Networkhardwareblocking:Somemodemsareknown tocauseissueswith your computer being in a firewalled state even thoughthey technically aren't routers. One notorious example is theMotorolaSurfBoardbrandofmodems,whichyoucanreadupaboutatthePortForward.comforums.

User error is also a very common problemwhen it comes to port

forwarding issues, but assuming that everything in the basic portforwarding guide was followed carefully, and none of the abovepossibilitiesareapplicable,thentheproblemverylikelylieswithanotherissue calleddoubleNAT. Unlike any of the other issues listed above,double NAT problems can often be taken care of, provided the userfollowsthenecessarystepsasdescribedbelow.

DoubleNATDouble NAT occurs when your computer is sitting behind two or

morerouters.InmostdoubleNATcases,itturnsoutthattheuserhasadedicated router,butwasalsounknowinglyprovidedwithamodembytheir ISP thatcamewith routeror firewallcapabilities.When that is thecase, the user simply forwards ports from the router to the computer,leaving the modem alone, and this is exactly where the problem lies.Because the modem acts as a router as well, if it is not configuredproperly,itessentiallymeansthattheuserremainsinafirewalledstate,since the dedicated router that the user did configure is not actuallyreceivingincomingconnectionsontheforwardedportduetoeverythingbeingblockedbytheoutermostrouter--themodem.Beawarethatthisisaspecificcaseoftheissueathand.Inmoreseverecases,userscanhavemorethanjusttworoutingdevices,andrectifyingtheproblemcanbecomethatmuchmoredifficult,dependingonthesolutiontaken.

RemovingorDisablingtheExtraneousRouterInthesimplestofcases,riddingyourselfofthedoubleNATsituation

comes down to simply removing the extra routers, or disabling theirrouting capabilities. Using this method assumes that the extraneousroutersbeingoperateduponareabsolutelyunneededonthenetwork.Ifthat is not the case, then the only solution you have is to chain portforward.Withthemethodbeingdescribedinthissection,onlyoneroutershould end up on the network, that router being the one that yourcomputersareactuallyconnectedto.Someexamplesareasfollows:

Youhaveamodemthatactsasarouter,adedicatedrouterthat isconnected to the modem, and then your computers that areconnectedtotherouter.Inthiscase,youshoulddisabletherouting

capability in themodem,so thatyou're leftwithonly thededicatedrouterasthesolerouteronthenetwork(whichistheoneconnectedtoyourcomptuers).

Youhaveamodemthatactsasarouter,tworouters,andallofthecomputers connected to the same router. In this case, you shoulddisabletheroutingcapabilityonthemodem,andremovetherouterthatnoothercomputersareconnectedto.

As you can see, the general rule of thumb is that you remove allextraneous routers. You'll notice, though, that the modem with routingcapabilitynevergets removed -- that'sbecause themodem function isimportant for allowing you to actually connect to the Internet. In anycase,todisabletherouterinthemodem,youhavetophysicallyconnectacomputerdirectly to themodem, thenvisit theconfigurationpage forthemodem.Beforeactuallydisablingtheroutingcapability,youmustbesure to checkwhether yourmodemcontains login information for yourISP.Ifitdoes,thenyouaregoingtohavetomakesureyouhaveacopyofthatinformationonhand.Thisismostoftenthecaseforpeopleusinga DSL modem and router, where login information is usually storedwhere thePPPoA/PPPoEconfigurationpage is.Thataside,setting themodem to bridge mode is what you should be combing through itsconfigurationpagefor.Afteryoudothis,everythingshouldhopefullybefine.IfyoufindthatyourInternetconnectionnolongerworks,youshouldfill the login information you copied into the appropriate location in theremaining active router on your network (if you copied PPPoA/PPPoEsettingsfromthemodem,copyit intothePPPoA/PPPoEsettingsintherouter).

ChainPortForwardingThismethodcanbeveryannoying,asitrequiresthatyousetstatic

IPsforandforwardthedesiredportthrougheachandeveryoneofthem.Basically,youneedtofollowthebasicportforwardingguideforeachandeveryrouter,exceptthattheIPyou'reforwardingtoistheIPofthenextrouter in thechainof routers leadingup toyourcomputer.Each routermustbeassignedastatic IPaddress,whichcannormallybeset in itsconfigurationpages.Whilespecificscan'tbedelvedintobecauseofthe

sheernumberofdifferent routersavailable, the followingcaseexamplemightbeofusetoillustratetheprocessmoreclearly:

Youhaveamodemthatactsasarouter.Adedicatedrouter(routerA) is connected to it. Another dedicated router (router B) isconnectedtorouterA.YourcomputerisconnectedtorouterB.

Themodem'sroutingsubnetstartswith192.168.1.x. It forwardsthe port specified in µTorrent to router A, which is at IP address192.168.1.5onthemodem'ssubnet.

RouterAhasastaticIPsetto192.168.1.5.Itsownsubnetstartswith172.16.1.x.ItforwardstheportspecifiedinµTorrenttorouterB,whichisatIPaddress172.16.1.3onrouterA'ssubnet.

Router B has a static IP address set to 172.16.1.3. Its ownsubnet starts with 10.0.0.x. It forwards the port specified inµTorrent to your computer, which is at IP address 10.0.0.6 onrouterB'ssubnet.

Your computer has a static IP address set to 10.0.0.6, andbecause theportwas forwarded from themodem to routerA,andfrom routerA to routerB, then from routerB to this computer, theportcheckerconsidersyourclienttobeconnectable.

Please be aware that thatwas just an example.Many conditions,including the IP addresses, the number of devices on your networksetup, or how everything is connected, will most likely differ from theexample. All you can do is adapt the example to your situation andconfigure everything accordingly. Setting the static IP addresses upproperly is extremely important when chain port forwarding. Anymistakes (or failure to do so)meansmore troubleshooting in trying tofigure out which device's IP address changed if your port suddenlybecomesunforwarded.

Insomecases,youmightfindthatyouneedtomoveyourfiles,beitdue to simple reorganization, possibly to reinstall Windows, or maybeeventomoveµTorrentandallthetorrentjobsalongwiththeircontentstoanewcomputer.

ReinstallingYourOperatingSystemIn the simplest of cases, reinstalling your operating system only

MovingtoaNewComputerMigratingµTorrenttoanewcomputersimplyrequiresthatyoucopy

your files to your new hard drive, along with backing up the entireµTorrentsettingsdirectory.Themostdifficultpartofthisprocesscomeswith theplacementof theµTorrentdirectoryand the torrentcontents. Ifyou want to complete the process with minimal effort, it becomes asimplematterofmakingsurethepathsforallthefilesrelatedtoµTorrentand the torrent contents on the new computer are identical to therespectivepathsontheoldcomputer.

If you had an encapsulated "installation" of µTorrent, an identicalusername is not necessary. Otherwise, if the µTorrent settingsdirectorywaslocatedin%AppData%\uTorrent,thenyouwillhaveto create a user with the same exact account name on the newcomputerason theoldcomputer, thenmove theµTorrentsettingsdirectoryintotheproperlocationondisk.Ifyouplanonmoving thedriveover to thenewcomputer, thenaslong as the drive letter remains the same, you save yourself theheadacheofdealingwithpaths.Otherwise, if you'regoing tocopythefilesfromtheolddrivetothenewdrive, thenyoushouldmakesurethetorrentcontents'pathsremainidentical.

Ifanyof thosetips fail,andyouareunable tokeeppaths identicalforeitherthesettingsdirectoryorthetorrentcontents,thenyou'reinforaverylongride,andwillhavetoperformeverythingasifyouhadmovedthetorrentcontents.

MovingTorrentContentsThisprocess,ifyouhaven'talreadyfigureditout,mightrequirethe

mostamountoftimeoutofanyofthe"migration"processes,asitmightrequire thatyouallowµTorrent toverify thedata integrityof the torrentcontents after the move. What's time consuming isn't really theprocedure itself, but the fact that rechecking can take a lot of time,dependingonthetorrentcontents'sizes,andhowmanydifferenttorrentjobs you want to move. All that's needed when you're moving torrentcontents is that you stop the torrent job in µTorrent, move the torrentcontentstowhereveryouneedthemtobe,setthedownloadlocationforeachassociatedtorrentjobforthemovedcontents,andstartthetorrentjob. IfµTorrentdoesn't recognize theexistingdata,stop the torrent jobandforcere-checkforeachrelevanttorrentjob.


SwitchingfromAnotherClient

Now that you've made the switch to µTorrent, you're probablywondering if or how you could import all the torrent jobs you wererunning in your previous client. Rest assured that the process is arelativelysimpleone,andonlyrequiresabitofpatience,dependingonhowmuchdata isbeing"imported" intoµTorrent-- thelargerandmorenumerous the torrent contents being imported, the longer it will take,because itallmeansthat thedata integritycheckingwill take longeraswell.

RemovingExtraExtensionsThere isasimplematter to tendto firstbeforeproceedingwith the

import,and thathas todowithaspecific feature insomeotherclients.Some other clients append a special extension to incomplete files toindicate that theyare incomplete,andµTorrent(if therelevantoption isenabled)isnoexception.Becauseofthisextension,µTorrentmighthavetroublerecognizingthetorrentcontents,andwillignoretheminstead.Tofix it, all you have to do is remove the special extension from anyincompletefile.Iftherearemanyfiles,thiscanquicklybecomeaboringandtedioustask.Luckily,asimplebatchscriptcanbeusedtorenameallfileswiththeunwantedextension:

@for/r%%iin(*.XT!)do@move"%%~fi""%%~dpni"

Copy and paste the above line of code to a new text file, thenchange the XT! to the extension you wish to remove. BitComet, forexample,appendsabc!extensiontotheendofincompletefiles,soyouwould replace theXT! in the scriptwithbc!.Now, save the text as abatch file (rename.bat, forexample),andall youhave todo ismovethebatch file to thedirectorycontaining filesyouwant to rename,andrun the script, then repeat for any other directory containing files youwanttoremovethespecifiedextensionfor.Notethattheabovescriptisrecursive,soany filescontainedwithinanyotherdirectory in thesame

directory as the batch file will be renamed as well if they have thespecifiedextension.

ImportingTorrentJobsWith extra extensions out of the way, the rest of the process is

That aside, you can start setting theprocessupasfollows:

1. In the Directories preferences, tick the "Put new downloads in"checkbox, untick the "Always show dialog on manual add"checkbox, and select thepath to thedirectory that all your torrentcontents are located in. Make sure the "Don't start the downloadautomatically"optionisleftunticked.

AlternativeOperatingSystems

In aworldwheremost end users only know about or are familiarwith Microsoft Windows, it's easy to forget that there are alternativeoperating systems out there, right? For those of you who aren't usingWindows, it's still possible to run µTorrent in your operating system, itjusttakesabitmorefussingaroundtogetitrunningmorenicely(thoughthere might still be residual problems in functionality due to operatingsystemlimitations).

RunningonWine(*BSD,GNU/Linux)WineisanopensourceprojectthataimstoimplementtheWindows

APIonUnix-likeoperatingsystems.Insimplerterms,it isanattempttoallow users running a Unix-like operating system (such as *BSD orGNU/Linux)toexecuteapplicationsthatnormallyrunonlyonWindows.The first step in running µTorrent on Wine would, naturally, be todownloadandinstall the latestversionofWinefromWineHQ.orgifyouhaven'talreadydoneso.

WhenWineisinstalled,theonlythingyouneedtodoisrunµTorrentbyusingthewinecommand ina terminalwindow.WhereveryouhaveyourµTorrent executable locatedat on your filesystem, yousimply runµTorrent with the command wineFULL_PATH (where FULL_PATH isthe full path to the µTorrent executable) in in the terminal window.Naturally,therearemanydifferent(andeasier)waystoexecuteµTorrentthrough Wine, but because there are infinitely many combinations ofsoftwaresavailableforuseontheUnix-likeoperatingsystems,themostgenericwaywillhavetosuffice.

SowhereexactlyisthehardpartinusingµTorrentonWine?It'sinthe limitations that come with using Wine and its incompleteimplementationof theWindowsAPI.Becauseof this,and the fact thatWine is unable to integrate too deeply with its host operating system,thereareseveralknownissuesyoushouldbeawareof:

Problemworkarounds:Someknown issueswithWinehavebeenworked around in µTorrent with a set of "hacks" enabled throughsys.enable_wine_hacks.

Boss-Key:Boss-keysdonotworkunderWine.

Graphical oddities: There are several oddities in the interfacerunningµTorrentunderWine...

By default, the interface sticks out like a sore thumb, with the gray Windowsapplicationwindowbackground inall itsglory.Userscanmodify the themecolors inthe"DesktopIntegration"tabofwinecfgtobetterintegrateWine-runapplicationswithsurroundingapplications.Ifthelist-viewhasablackbackground,thenmakesuretheWindowsversionissettoWindowsXPinwinecfg.

Open Containing Folder: Because Open Containing Folderattempts to open a Windows Explorer process, and the nativeWindowsExplorerisnotpresentonalternativeoperatingsystems,itwill open theWine implementation,which looksunimpressive,anddoes not work very well. Unless you can tolerate it, don't botherusingthisfeatureunderWine.

OpenFile: "Open" in the torrent jobs list contextmenu or on theFilestabwillnotwork,astheyattempttorunaWindowsapplicationassociatedwiththefiletype,butsincetherearenone,theyfail.

Settings directory: Because Windows environment variables donot apply in alternative operating systems, it naturally follows that%AppData% does not either. You'll find that the µTorrent settingsdirectory is actually located at~/.wine/drive_c/windows/profiles/USERNAME/Application

Data/uTorrent, where USERNAME is your username on theoperatingsystem.

Start on system startup: Because alternative operating systemshavedifferentmethodsofbootingapplicationsatstartup, theusualmethodsofaddingastartupentryinWindows(beitintheRegistry,or in theStartmenu)won'twork.StartµTorrentonsystemstartup

shouldbedisabled.

Systemtray:ThesystemtrayfeaturehasbeenreportedtobeflakyunderWine, so if you have issues using it, you should disable allrelevantoptions.

.torrent file association: Due to the inability ofWine tomap fileassociations to applications run through Wine, the feature isrendereduseless.Checkassociationonstartupshouldbedisabled.Analternativemethodof"emulating"fileassociationwouldbetousethe auto-load torrents feature to tell µTorrent to automatically loadfilesfromadirectoryonyourfilesystem.Inthatway,youcansimplydragordownload .torrent files into thatdirectory,and ifµTorrent isrunning,itwillautomaticallyloadthenewfiles.

RunningonDarwine(MacOSX)Note:ThereisanativeµTorrentclientforMacavailablehere.Ifyou

haveanolderversionofMacOSX(10.4orbelow)youmayneedtousetheinstructionsbelow.

Darwine is a port of Wine for use on Darwin and Darwin-basedoperatingsystems,suchasApple'sMacOSX.Darwine requiresanXservertowork,soifyoudon'talreadyhaveitinstalled,youcanfindtheinstaller in the Apple Restore DVD, or by downloading it along withApple'sXCode.

Installing Darwine should be a cinch. Just as with Wine, it'sgenerallybesttodownloadandinstallthelatestversionofDarwine.Afterinstalled,youshouldbeabletosimplydouble-clickµTorrent'sexecutablefile,andDarwineshouldautomaticallyruntheapplication.Ifnot,thenrunWineHelper.app (which should be located in the installed Darwinedirectory)thenopenµTorrent'sexecutablefile.That'sall!

WARNING: Unless you fully understand the consequences ofchanging an advanced setting, you should not modify it withoutguidance.

Notes:

3.3: This option is applicable only from µTorrent version 3.3 andabove

bt.allow_same_ip: Enabling this option allows multiple incomingconnectionsfromthesameIPaddress.Thisoptionaffectsasingletorrent job at a time, so you can still have the same IP addressconnecttoyouondifferenttorrentswarms.It isrecommendedthatthisoptionbeleftdisabled,asitweakenstheanti-leechprotection.

bt.ban_threshold: This option specifies the maximum number ofhashfailed pieces any single peer can send before µTorrent takesactionagainstit(eitherbanningitoutright,orenforcingbt.ban_ratioifbt.use_ban_ratioisenabled).

bt.compact_allocation: Enabling this option allows µTorrent tocreatefilesinamannersuchthatthedataareincrementallywritten

to disk without file pre-allocation. Because writes are compact,enabling this option may potentially lead to an increased level ofdiskfragmentationwhilethefileremainsincomplete.Inaddition,thisoptionfurtherdecreasesthealready-lowprobabilitythatafilecanbepreviewed before completion, since it may write the data for in-progress files out of order. Here are some things to take note ofwhenusingthisoption:

bt.determine_encoded_rate_for_streamables: Enabling thisoptionshowsmediafiles'rateinFilestab

bt.enable_pulse:Enabling thisoptioneffects ratings,anddisablescommentstoo.

bt.enable_tracker: Enabling this option enables the rudimentarytracker embedded in µTorrent. If you wish to use this tracker, theURLislocatedathttp://IP:port/announce,whereIP isyourWAN IPaddress,andport is theport µTorrent is listening on (orthe alternative listening port if set and enabled). If you use adynamicDNSservice,yourdomainmaybeusedinsteadofyourIPaddress.Theembedded trackerallows trackingofexternal .torrentfiles, and provides noway to limit them. There is no interface forviewing the .torrent files that are tracked. It is imperative thatµTorrentisabletolistenforincomingconnectionsforthisfeaturetowork properly, so you have to make sure you have completelyforwardedyourportsinordertousetheembeddedtracker.

bt.graceful_shutdown: If enabled,µTorrentwill take as long as itneedstofinishitsshutdownsequence(writingin-progresspiecestodisk,deletingfilesindeletionqueue,andwaiting for trackerreplies

Ifdisabled,µTorrentwilllimithowlongitwaitstoto10seconds,andregardlessof the state of the shutdown sequence, µTorrentwill force itself toexit.

bt.prioritize_partial_pieces: Enabling this option ('True'), tellsµTorrent toalways try to requestblocks frompieceswe'vealreadystarted.

diskio.minimize_kernel_caching : This option disables compactallocation,mightbePOSIXonly3.3

diskio.no_zero: Enabling this option causes µTorrent to skip thezero-filling process for file allocation. This option works only onWindows XP or newer, and requires administrator privileges bydefault. However, it is possible to make this work on limitedaccountsbysettingthe"Performvolumemaintenancetasks"policyappropriately in theWindows Group Policy Editor. Skipping zero-filling speeds up the file allocation process, but because theallocated files have shared read access, there is a risk that anysensitivedatathatmayhaveonceexistedatthatlocationindiskbutisn't wiped will potentially be exposed for other applications andusers to read, including those without volume maintenanceprivileges.

diskio.quick_hash: Toggles advanced optimizationwhen verifyingatorrentdata'sintegrity.

diskio.smart_hash: This option makes µTorrent hash data frommemory(ifinthewritequeue)insteadofflushingtodisk,re-readingfrom disk, and then hashing. This should help reduce hard diskreads,especiallywhentransferringathighspeeds.

SettingsDirectory

Although µTorrent is mostly self-contained, there has to be alocation where it can store its settings for later use after the first run.BecauseµTorrentdoesnotusetheWindowsRegistry,ithastostoreitsconfigurationinfilesonseparatefilesonthedisk.Bydefault,thosefilesarelocatedat%AppData%\uTorrent,whichcanbeeasilyaccessedbyvisiting"Start">"Run" (orbypressing Windows + R onthekeyboard),typing it into the "Open" field, and pressing "OK." Typically, you'll findseveral.datfilesinthesettingsdirectory:

dht.dat contains information regarding DHT that µTorrent useswhenconnectingtotheDHTnetwork.resume.datcontains information regardingcurrently loaded torrentjobs.rss.datstoresallRSS-relatedsettings,andalsoholdsthehistoryofpreviouslydownloadedtorrentjobs.ThisfileonlygetscreatedifyouusetheRSSDownloader.settings.dat contains most of the settings in µTorrent, and alsocontainstheinformationlistedinthestatisticsdialog.

Notethatitisnormaltofind.dat.oldand.dat.*.badfilesinthesamedirectory. The former file type denotes good backup files for thecasethatthecorresponding.datfilebecomescorrupted.Thelatterfiletype denotes backups of corrupted files, which may be sent to thedeveloperforanalysisifnecessary.

In addition to .dat, .dat.old, and .dat.*.bad files, µTorrentstores loaded .torrent files in its settings directory unless a storagelocationisspecified.ThesefilesneedtobestoredinorderforµTorrenttowork properly, so do not delete them unless you are absolutely sureµTorrent no longerhas theassociated torrent job loadedany longer. Ifyouwant µTorrent to delete the stored .torrent files automatically uponremovalof the torrent job,see thedescriptionof theRemovebutton inthetoolbar.

2. Createashortcutforthiscopyoftheexecutable.3. Edit the shortcut's target by adding /RECOVER to the end of the

"Target"path,outsideofanyquotationmarks,andseparated fromtheexecutablepathbyaspace.

With magnet URIs, µTorrent does not have a copy of the infodictionary on hand, so it does not know the name or the contents.

Consequently,itmustwaittofindasourcewiththedictionary,whichmaysometimes takea long time.Becauseof this,µTorrentuses thedefaultdownload locationas thedestination for the files(incase ithappens tofind the info dictionary when the user is not available to set thedownload location manually).

µTorrent. They can make torrent job identification and sorting mucheasierforyou.

DoesµTorrentworkwellonWindowsXPSP2orhigheroperatingsystemswithanunpatchedTCPIP.sys?

Yes, by default, µTorrent will make at most 8 simultaneousconnectionattemptstoworkwithinthe10connectionattempt(half-openconnection)limitontheseoperatingsystems.

Patching TCPIP.sys to a higher limit may help if you are havingproblemswithyourInternetconnection,thoughincreasingthelimitmayalso cause some routers to freeze up (due to the increased rate ofsimultaneousconnectionattempts).Ifyouwouldstillliketopatchthefile,downloadtheEventID4226PatcherfromLvlLord.de.

Beware that in most cases, you should refrain from setting theTCPIP.syslimittoanynumbergreaterthan50,astherearefew(ifany)benefits to be gained from higher numbers. Also understand thatnet.max_halfopen should always be set to a number lower than theTCPIP.sys limitsetby thepatcher (atmost80%of theTCPIP.sys limitonly). For more information on how (or whether) the half-openconnectionlimitshouldbeset,seethisFAQentry.

Microsoft hasmade a habit of reverting theTCPIP.sys connectionattemptlimitthroughWindowsUpdate,which(formanyusers)occursonamonthlybasis.IfyoudecidetopatchyourTCPIP.sysfileandraisethenet.max_halfopen limit alongwith it, then remember to repatch the fileeverytimeyouperformaWindowsUpdate(otherwise,you'llmostlikelyrunintoconnectiontroubles).

WhatportshouldIuseforµTorrent?

It is generally recommended that you not pick ports in the6881-6889 range, as they are commonly throttled by ISPs. Since no singleport has inherent advantages over any other port, you can simply letµTorrentpickarandomportforyou.

WhatshouldIsetmyhalf-openconnectionlimitto?To answer this question, a bit of background information may be

required. The "half-open" (technically, "embryonic") connection limitcontrols how many connections µTorrent will attempt to establishsimultaneously at any given time. Half-open connections are just likephonecallsthathaven'tyetbeenpickedupbytheotherendoftheline.Thehalf-open connection limit controls the number of such "calls" youcanattempttomakeatanygiventime,butdoesnotlimithowmanyfully-established connections (phone calls that are successfully picked upfromtheotherend)youcanmakeintotal.

An important point to note (that is commonly misunderstood andmisrepresented) is the fact that thehalf-openconnection limitdoesnotaffect the overall speed at which the you can download or upload. Atbest, increasing thehalf-open limitmaydecrease theamountof time ittakesforµTorrenttoattaindecentspeeds,butthatonlylastsforthefirstfewminutesatworst.Afterseveralminuteshavepassed,theconnectionlimitwillhavealreadybeenreached if thereareenoughpeersanyhow,so at that point, there is no difference between a low half-openconnectionlimitandahighlimit.

Highhalf-openlimits,ontheotherhand,causeconnectionproblemsfor many users because Microsoft limits the number of half-openconnections able to be made globally in certain versions of Windows(startingwithWindowsXPwithSP2,uptoWindowsVistawithSP1). Itcanbepatched,but for littlegain,asalreadyexplainedpreviously(andMicrosoft resets the limit every so often with some Windows Updateanyhow). Even if your half-open connection count isn't limited byTCPIP.sys (either throughpatching,oryou'reusinganOS thatdoesn'timposesuchalimit),anincreaseinthehalf-openlimitwouldfallintothe

exactsamelimitationsinefficacyasdescribedabove.

The rationale behind Microsoft's decision to limit half-openconnections is that relatively few legitimate and properly-designedapplicationscanbeexpectedtorequiremanyhalf-openconnections.Ontheflipside,ifanapplicationisattemptingtoestablishalargeamountofconnections in a very short period of time, it is usually a sign that theapplication isapieceofmalwareattemptingtocommunicatewithothercomputers.

Whyanyonewould recommend thatusers increase theirhalf-openlimits as a general speed tweak that everyone should apply isincomprehensible. It doesn't actually helpwith speeds beyond the firstfewminutesatmost,andcomeswiththedetrimentaleffectofpotentiallykilling connections formany users. The only potential exception to the"you don't need to increase your half-open connection limit" rule ofthumb is if you have a connection with a very fast upload rate (think"several megabits per second"), and have many torrent jobs startedsimultaneously.Inthatsituation,itmaybebeneficialtoincreasethehalf-open connection limit in order for µTorrent to be able to communicate(within a reasonable amount of time)with the large pool of peers andtrackersassociatedwithstartingmanytorrentjobssimultaneously.

In instances where raising the half-open connection limit isunavoidableornecessary, theusershouldkeep inmind thatµTorrent'snet.max_halfopen limit should never be set to a value greater thanapproximately80%oftheTCPIP.syshalf-openconnectionlimit.SoiftheTCPIP.sys limit is 100, the highest anyone should set µTorrent'snet.max_halfopenshouldbe80.Thatdoesn'tmeanitneedstobe80%either--itcanbeless.That'sjustasafelimitguidelinetomaintainqualityofconnection.

WhyamIstillreceivingincomingconnectionattemptsafterIhavealreadyclosedµTorrent?

In BitTorrent, peers disconnect from the swarm without notifying

everyotherpeer in theswarmbecause itwouldbe inefficient todoso,andalsobecausepeers rarelyhave the IPsofeveryotherpeer in theswarm(whichwouldmakeitimpossibletodointhefirstplace).BecausemostBitTorrentclientscachepeerinformation,whentheytrytoconnectto a particular peer in their cache, they may end up attempting toconnecttoapeerthathasalreadydisconnectedsincetheylastreceivedthepeer'sIPandportnumber.

This phenomenom is what you are observing when you seeincoming connection attempts after you've exited µTorrent. DependingonhowmanypeershadacopyofyourIPandportnumberintheirpeercache, this can take up to several weeks to subside. Having DHTenabledmaymagnify theeffects,as therearemanymorepeersusingDHT than thereare connected toanyoneparticular torrent swarm (somore users may have your IP and port number by the time youdisconnect). Although there is no way to prevent this from occurring,disablingDHTmay reduce theamountof timeneeded for this to taperoff. Assuming your network is properly protected, these connectionattemptscanbesafelyignored.

Glossary

Especially ifyou'renewtoBitTorrent ingeneral, thereareprobablymany new and unfamiliar terms used throughout this manual (and inmanyotherBitTorrent-relatedplaces).Tohelp"clue"you inon thenewvocabulary,thisglossarycanbeofgreathelp.

Aannounce

Theactofconnecting toa tracker toupdate itonyourstatus,and to obtain information from it as well, including (but notlimitedto)anupdatedpeerlist.

availabilityThenumberofcompletecopiesofthetorrentcontentstherearedistributed in the part of the swarm you're connected to. Theamountofthetorrentcontentsyoucurrentlyhaveisincludedinthe availability count. A swarm with no seed and with anavailabilitybelow1.0will likelybeunabletofinishtransferringthecompletetorrentcontents.

Bblock

Theunitsofdatathatcompriseapiece.Becauseblocksdonotdirectly affect whether torrent contents are considered to befinished transferring, it is not seen as an appreciable unit ofdatawithregardstoBitTorrentlikethepieceis.

byteA unit used for measuring the size of data on a computerstorage device. Many people confuse "byte" for "bit" whenreferringtospeeds.Abyteiscomposedof8bits,sothereisa

cleardistinction,andterminologyshouldnotbeconfusedwhenreferringtobytes.

broadcatchingTheactofdownloadingcontentfromanRSSfeed.

Cchoked

ThisworddescribesthestateofaBitTorrentconnection.Whenaconnection ischoked, itmeans thepersonwho issupposedtobedoing theuploadingon theconnectiondoesnotwant tosend anything. This generally happens when the uploader'suploadslotsarefull.

clientTheapplicationauserisusingwhenconnectedtoaswarm. Inthis case, the application being used to connect to swarms isµTorrent,soitistheclient.

DDHCP(DynamicHostConfigurationProtocol)

A protocol that allows networked devices to be assigned anunique IP address automatically from a pool of unused IPaddresses.

DHT(DistributedHashTable)Adistributedtracker thatworkssimilarly toaregular tracker inthat you announce to it and get back a list of peers that aretransferring the same .torrent file as you. Because DHT isdistributed,thereisnosinglepointoffailure,soevenifasinglenode disconnects fromDHT, the tracker will continue to work(unlikewithnormal trackers,where if theservergoesdown, itbecomes unusable). DHT can be thought of as a backuptracker.

diskcacheAfeaturethatmakesuseofavailablememorytostoresdataforquicker access as well as ease disk thrashing. The use of adiskcachewillcauseanincreaseinmemoryusageinreturnforimprovedperformance.

diskthrashingWhenastoragediskgetsaccessedvery frequently.Extendeddiskthrashingmayleadtoharddrivewearandtear,shorteningadrive'slife.

doubleNATAsituationwhere thenetworkdevice isbehindmore thanoneNAT devices (generally routers). In this situation, forwardingports from just one of those NAT devices is generallyinsufficient,andmoreactionsneedtobetakenasdescribedintheadvancedportforwardingguide.

downloadThe act of transferring data from another computer onto yourown.

Eencryption

endgamemodeAchange in thepiece requestingstrategy thatoccurswhenadownload is near completion during which the client requestspiecesfromallconnectedpeersratherthanrequestingapiecefrom one peer at a time in the normal operating mode.Endgame mode is used because download rates often slowdownconsiderablyasatorrentjobnearscompletionduetothetendencyfortheremainingpiecestobedownloadedfrompeerswith saturated connections. By requesting data from all peers

rather thanwaitingforasinglepeer,suchabottleneckcanbebypassed. This mode is not used during normal operatingmodesbecauseof the largeamount of overhead it potentiallygeneratesinsendingrequeststoallpeers.

ephemeralportrangeA range of port numbers automatically allocated by theoperatingsystemforusebyanyapplicationonthesystemwithnetworkaccess.Portsintheephemeralportrangearetypicallyused to make temporary outgoing connections.

Hhalf-openconnection

A connection that is not fully established on both ends. Half-openconnectionsoccurwhenyouattempttoconnect toanIP

address,buttheIPaddresshasn'tyetresponded.

hashA "fingerprint" of data assumed to be unique to the data.Becauseof theassumeduniquenessof thedata, it isused toverify that a piece of data is indeed uncorrupted (since thecorrupteddata'shashwouldnotmatchitsexpectedhash).

hashcheckThecomparingofapieceofdata'shashwithareferencehashinordertoverifytheintegrityofthepieceofdata.

hashfailWhenapiecefailsthehashcheckusedtoverifydataintegrity.

Iindex
