There are senior members on the forums who serve as Moderators. 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.

Default Writing Java client.. how should I implement query/query hits?

I am trying to write my GNUTella client using Java.

I wrote the code to find the first node on the network, then sent to it the "CONNECT GNUTELLA/0.6" message.

The servent correctly says "200 OK", and then.. how can I perform a search query?

At this point I got:
* the IP and port of the servent I am connected to
* its input and output streams.

The RFC says
The message header is 23 bytes divided into the following fields.

Bytes: Description:
0-15 Message ID/GUID (Globally Unique ID)
16 Payload Type
17 TTL (Time To Live)
18 Hops
19-22 Payload Length
A Query message has the following fields:

Bytes: Description:
0-1 Minimum Speed. The minimum speed (in kb/second) of servents
that should respond to this message. A servent receiving a
Query message with a Minimum Speed field of n kb/s SHOULD
only respond with a Query Hit if it is able to communicate at
a speed >= n kb/s.

2- Search Criteria. This field is terminated by a NUL (0x00). [...]
The Search Criteria is text, and it has never been specified which
charset that text was encoded with. Therefore, servents MUST assume
it is pure ASCII only.
so I built byte by byte the message giving a search criteria like "madonna" or stgh like that.

Finally I printed the bytes array to the output stream connected with the servent, but:

* if I read the servent reply on the input stream I got unuseful information about the servent.. nothing like the query hits

* if I create a ServerSocket bound to port 6346, this socket hungs on listening an never recieves anything

So.. what shall I do to get the query hits?

Thanks in advance

I am also working with the protocol and trying to write my own client, but mine will be in Perl. I ran into a problem that sounded similar to yours.

I would send:


They would send:

GNUTELLA/0.6 200 (...)

And from what I was reading on all the documentation I could find about the protcol, it said that you should now be connected and able to send/receive ping/pong/query/queryhits.

But when I attempted to do any of this and read from the socket for my response, I would find (like you said) useful (text) information about my server. I would then eventually be disconnected from the server in less than a minute.

What I found out from (after hours of searching) an alternative document, that the handshake actually goes like:


GNUTELLA/0.6 200 (...)\r\n
(optional server specifics)\r\n

GNUTELLA/0.6 200\r\n

And now, at this point you are offically connected, and we remain so indefinatly. And from what the documents say, you should now be able to send and receive ping/pong/query/queryhits.

I am not actually trying to work with sending a query at the moment, instead I am trying to understand how to send a ping.

This is where I become lost again. The protocol documentation that I have found is ver unclear about the specifics for sending communications at this point.

I hope the information I have shared will atleast help you get properly connected to the network. But as for the problem of sending a query, (or ping in my case) I do not know what to tell you.

Best of luck,
