These volunteers keep the board organized and moving. Moderators are authorized to: (in order of increasing severity) Move posts to the correct forums. Many times, members post in the wrong forum. These off-topic posts may impede the normal operation of the forum. Edit posts. Moderators will edit posts that are offensive or break any of the House Rules. Delete posts. Posts that cannot be edited to comply with the House Rules will be deleted. Restrict members. This is one of the last punishments before a member is banned. Restrictions may include placing all new posts in a moderation queue or temporarily banning the offender. Ban members. The most severe punishment. Three or more moderators or administrators must agree to the ban for this action to occur. Banning is reserved for very severe offenses and members who, after many warnings, fail to comply with the House Rules. Banning is permanent. Bans cannot be removed by the moderators and probably won't be removed by the administration. The Rules 1. Warez, copyright violation, or any other illegal activity may NOT be linked or expressed in any form. Topics discussing techniques for violating these laws and messages containing locations of web sites or other servers hosting illegal content will be silently removed. Multiple offenses will result in consequences. File names are not required to discuss your issues. If filenames are copyright then do not belong on these forums & will be edited out or post removed. Picture sample attachments in posts must not include copyright infringement. 2. Spamming and excessive advertising will not be tolerated. Commercial advertising is not allowed in any form, including using in signatures. 3. There will be no excessive use of profanity in any forum. 4. There will be no racial, ethnic, or gender based insults, or any other personal attacks. 5. Pictures may be attached to posts and signatures if they are not sexually explicit or offensive. Picture sample attachments in posts must not include copyright infringement. 6. Remember to post in the correct forum. Take your time to look at other threads and see where your post will go. If your post is placed in the wrong forum it will be moved by a moderator. There are specific Gnutella Client sections for LimeWire, Phex, FrostWire, BearShare, Gnucleus, Morpheus, and many more. Please choose the correct section for your problem. 7. If you see a post in the wrong forum or in violation of the House Rules, please contact a moderator via Private Message or the "Report this post to a moderator" link at the bottom of every post. Please do not respond directly to the member - a moderator will do what is required. 8. Any impersonation of a forum member in any mode of communication is strictly prohibited and will result in banning. 9. Multiple copies of the same post will not be tolerated. Post your question, comment, or complaint only once. There is no need to express yourself more than once. Duplicate posts will be deleted with little or no warning. Keep in mind a forum censor may temporarily automatically hold up your post, if you do not see your post, do not post again, it will be dealt with by a moderator within a reasonable time. Authors of multiple copies of same post may be dealt with by moderators within their discrete judgment at the time which may result in warning or infraction points, depending on severity as adjudged by the moderators online. 10. Posts should have descriptive topics. Vague titles such as "Help!", "Why?", and the like may not get enough attention to the contents. 11. Do not divulge anyone's personal information in the forum, not even your own. This includes e-mail addresses, IP addresses, age, house address, and any other distinguishing information. Don´t use eMail addresses in your nick. Reiterating, do not post your email address in posts. This is for your own protection. 12. Signatures may be used as long as they are not offensive or sexually explicit or used for commercial advertising. Commercial weblinks cannot be used under any circumstances and will result in an immediate ban. 13. Dual accounts are not allowed. Cannot explain this more simply. Attempts to set up dual accounts will most likely result in a banning of all forum accounts. 14. Video links may only be posted after you have a tally of two forum posts. Video link posting with less than a 2 post tally are considered as spam. Video link posting with less than a 2 post tally are considered as spam. 15. Failure to show that you have read the forum rules may result in forum rules breach infraction points or warnings awarded against you which may later total up to an automatic temporary or permanent ban. Supplying system details is a prerequisite in most cases, particularly with connection or installation issues. Violation of any of these rules will bring consequences, determined on a case-by-case basis. Thank You! Thanks for taking the time to read these forum guidelines. We hope your visit is helpful and mutually beneficial to the entire community. |

C++ sample??? Hello, I'm an experienced C++ developer, but very new in developing internet applications. Now I have to develop a small Gnutella-client (for just to become familiar with the gnutella protocol) in C++. It's just a little private project to learn how P2P works. Does anybody know some C++ sample code which I can refer for a startup? Thanks Wolli |

Here's a very nice Gnutella program one in C - you should easily get samples there: - gtk-gnutella - The Graphical Unix Gnutella Client Also there's Shareaza in C++, but that one's a multinetwork and the last time I checked its Gnutella implementation wasn't that advanced (bad track record) and it's Windows only: - Shareaza - Bringing P2P Together Did you already read Gnutella for Users - Gnufu and GDF - LimeWire ?

Gtk-Gnutella also offers nice API-Docs in which you can look at the source: gtk-gnutella: gtk-gnutella

Was schicke ich denn nun..... Uuups, I wrote this mail in german language. Sorry! See english translation below ------------------------------------------------------------ Hallo, zunächst schon mal vielen Dank für eure bisherigen Infos, die haben schon ein wenig geholfen. Das eigentliche binäre Gnutella-Protokoll kriege ich - hoffe ich - gut in den Griff. Probleme bereitet mir die Verbindungsaufnahme zu einem anderen Servent. Ausgehend von einer gültigen Tcp-Verbindung zu einem Servent möchte ich mich nun mit diesem verbinden. Dazu fand ich in einem Buch folgende Informationen, was ich schicken muß: Quote:
Was genau schicke ich jetzt zu dem Servent? z.B. einen String der Form "CONNECT/0610.11.33.2:4222........" (ist wahrscheinlich Blödsinn) oder ein binäres Datenpaket wenn ja in welchem Format.... Vielen Dank das ihr einem P2P-Neuling helft. Wolli ------------------------------------------------------------ english Version: Hello, thanks to all for your information, they really helps. I believe I will not have problems with the binary gnutella protocol. But I have serious problems to connect to another servant. Assuming I have a valid TCP-Connection to a servant I want to connect to it. I found the follwing information in a book: Quote:
What excactly have I to send to the Servent? a formatted string like: "CONNECT/0610.11.33.2:4222........" (I think it's nonsense) or a binary package, but if so what's the format of this....??? Thanks again for your assistance to a P2P newcomer... Wolli Last edited by graytornWW; September 30th, 2009 at 02:13 AM. |

Falls du http wirklich selbst implementieren willst (brauchst du auch für den Download später noch, daher bietet sich eine Bibliothek an): RFC 2616 (rfc2616) - Hypertext Transfer Protocol -- HTTP/1.1 Tipp: installier' dir ein Gnutella-Programm wie Phex oder gtk-gnutella und sniff die Verbindung. Oder schau einfach, was das andere Programm schickt, wenn es sich mit dir verbinden will. - Phex - Home - gtk-gnutella - The Graphical Unix Gnutella Client Viele Erfolg! PS: Ein Gnutella-Programm zu schreiben bedeutet mehrere Personen-Jahre Arbeit, daher könnte es deutlich effizienter sein, einfach bei einem etablierten Programm mitzumachen, nachdem du die Grundlagen beherrscht. PPS: Damn, this should have been in english... sorry to all english speaking members

Also, solltest du wirklich bei der Gnutella-Programmierung einsteigen wollen, werden wir dich gerne als Entwickler aufnehmen, denn wie bereits gesagt, unsere Gnutella-Implementierung ist - gelinde gesagt - sehr einfach, und wir wuerden uns wirklich freuen, wenn sich jemand die Muehe macht, hier und da ein paar Verbesserungen vorzunehmen. Fuer Fragen steht unser Entwicklungsteam auch zur Verfuegung (Englisch oder Russisch ). Den Quellcode kann man uebrigens wie bei allen OpenSource Programmen einfach von SourceForge.net herunterladen. Ich nehme mir mal die Freiheit, auf unser Wiki zu verlinken, wo eine Seite mit Dingen, die bei der Kompilierung von Shareaza zu beachten sind, aufgefuehrt wird: SourceForge.net: Developers - shareaza BTW, Phex und gtk-gnutella sind uebrigens sehr gute Programme, was ihre Implementierung dieses Netzwerkes angeht (Ich moechte ja nicht nur Werbung fuer eine Seite machen ). EDIT: Hier kannst du nachsehen, wie Shareaza mit dem gnutella-Netzwerk (und allen anderen Netzwerken) umgeht: https://sourceforge.net/apps/mediawi...wShareazaWorks ------- To keep it short for those who don't know German: I've told him the Shareaza community would welcome him as a Gnutella dev (as we really need one, there we all agree^^) and reply to questions if he needs further information. I've also posted a wiki link on how to compile Shareaza. My PS states that Phex and gtk-gnutella are good programs, too. EDIT: expl about how Shareaza deals with its different networks: https://sourceforge.net/apps/mediawi...wShareazaWorks

(I remember seeing it a few months/years back, but I didn't spot it on the website and my package manager doesn't have Shareaza)

I just want to inform myself about the gnutella network a little bit. I'm very interested in this topic, and probably I will join a running project in the future.... The actual state of my little "gnutella client" (I called it "tifofi") is: A simple Qt-application wich is able to connect to multiple servent. I can trace the connections, and a list view shows me the files the servents provide to the network. But there is no download functionality at the moment. Ii takes 3 days to write this well documented c++ code, probably a base for more..... Quote:
but at the moment I stop the development at this point... let's see what the future brings...... Wolli |

http:// IP:PORT/uri-res/N2R?urn:sha1:SHA1_HASH_IN_BASE32_UPPERCASE Since you should already know the sha1 hashes of the files of others, this would make your client functional at once PS: Which two free projects do you work on? PPS: Congratulation!
