Publish content

Ossia mettere a disposizione(in share) del contenuto(files, directories --cartelle--). Dato che bittorent è parecchio conosciuto faccio dei paralleli per capire meglio somiglianze differenze.

A differenza di bittorent

In order to share files with other GNUnet users, the files  must  first be  made  available to GNUnet.  GNUnet does not automatically share all files from a certain directory.  In fact, even  files  that  are  downloaded are not automatically shared.

Il concetto del pseudonimo o namespace--Protezione per lo spam

gnunet-pseudonym  is  a tool for managing pseudonyms and namespaces. A pseudonym is the persona that controls a namespace.   As  such,  it  is identical  to  a public-private RSA key pair. A namespace is a collection of files that have been signed by the  corresponding private  RSA key. A  namespace  is  typically associated with a nickname and other metadata.

Namespaces are an important tool for providing assurances about content integrity  and authenticity in GNUnet.  Since all of the content in the namespace must have been provided by the same entity, users can form an opinion about that entity and learn to search (or avoid) certain namespaces.

gnunet-pseudonym can be used to list all of the  pseudonyms  that  were created  locally, to create new pseudonyms, to delete existing pseudonyms (the namespace will continue to exist, but it will  be  impossible to  add  additional data to it) and to list all of the namespaces (with their meta-data) known to the local user.  By default, gnunet-pseudonym lists all pseudonyms that were discovered so far.

Creating  a  new pseudonym requires using the -C option together with a nickname that is to be used  for  the  namespace.   Nicknames  must  be unique  for  each  user, global uniqueness is desireable but not necessary.  If two namespaces in GNUnet use the  same nickname  all  GNUnet tools  will  display  the nickname together with a number which ensures that the name becomes locally unique to  avoid  ambiguity.   Additional options can be passed together with the -C option to provide additional meta-data that describes the namespace.   Possible  meta-data  includes the  'realname' of the person controlling the namespace, a description,the mime-type for content in the namespace (useful if the namespace is dedicated to some  specific type of content) and contact information. One important piece of meta-data that can be specified is  the  identifier  of  a  document root, that is the name of a file in the namespace that is a portal to the rest of the content.  This is  useful  to  help users  find  this root in the absence of conventions.  Note that all of this meta-data is optional and should never be trusted blindly.

As mentioned before, by  default,  gnunet-pseudonym simply lists the meta-data available for other namespaces.  Namespaces can be discovered whenever the  peer  obtains  the  namespace advertisement. Namespace advertisements  can  be found using ordinary keyword-based searches (by default gnunet-pseudonym publishes the  namespace  advertisement  under the keyword 'namespace', but the -k option can be used to specify other keywords) and under the 'empty' identifier of the respective  namespace (using a namespace-search if the namespace ID is already known).

Since keywords can be spammed (any user can add any content  under  any keyword),  GNUnet supports namespaces.  A namespace is a subset of the search space into which only the holder of a certain pseudonym  can  add content.   Any  GNUnet  user  can create any number of pseudonyms using gnunet-pseudonym. Pseudonyms are stored in the user's GNUnet directory. While  pseudonyms  are locally identified with an arbitrary string that the user selects when the pseudonym is created, the namespace is  globally  known  only  under  the  hash of the public key of the pseudonym.Since only the owner of the pseudonym can add content to the namespace, it  is impossible for other users to pollute the namespace. gnunet-publish automatically publish the top-directory (or the only file if only one file is specified) into the namespace if a pseudonym is specified.

It  is  possible to update content in GNUnet if that content was placed and obtained from a particular namespace.  Updates  are  only  possible for  content  in namespaces since this is the only way to assure that a malicious party can not supply counterfeited  updates.   Note that  an update  with  GNUnet  does not make the old content unavailable, GNUnet merely allows the publisher to point users to more recent versions. You can  use  the  -N option to specify the future identifier of an update. When using this option, a GNUnet client that finds  the  current  (-t) identifier  will automatically begin a search for the update (-N) identifier.  If you later publish an update under the (-N) identifier, both results will be given to the user.


Per favorire la privacy
1. Come per i bittorent privati(non pubblici come quelli che si trovano in siti di indexing tipo Pirate Bay) qui una volta pubblicato il contenuto la controparte per trovarlo deve sapere(gli dobbiamo dare) la keyword(il corrispondente dare mano mano il file .torrent --privato appunto--) per usare gnunet-search se no non può trovarlo e scaricarlo. Altrimenti dovrebbe tirare a indovinare compito alquanto difficile

2. A differenza di bittorent una volta fatto stop al demone il file non è più disponibile. In bitttorent come si sa una volta fatto un seed  completo dalla sorgente essa potrebbe smettere a fare seed perchè ormai il file è nello swarm

In primis creiamo un pseudonimo che identificherà univocamente tutto ciò che pubblichiamo

Codice:

$ gnunet-pseudonym -C harrykar

faccio una verifica per vedre se davvero si è creato il local namespace(-o sta per --only-local)

Codice:

$ gnunet-pseudonym -o
harrykar (35P51F70DED1M47BAHAN0ETJ77TSM6HEIC7QIRI2UVHFRCQN7KEQTOVUROKTJ0OO83G22RE7G6B5T33J366EEVLETSJVA9VGN2E75C8)

Mentre per ricerca e download si trova qualcosa in Google (dalle release precedenti) per il share di files per la release 0.9 il cmd è stato cambiato da gnunet-insert a gnunet-publish quindi diamo un' occhiata al suo man.

Per testarlo ho fatto il publish di 2 file che si possono anche scaricare quando ho il server gnunet on

-k: impostazione keywords per la ricerca del file nella rete gnunet

Per più informazioni:

Codice:

$ man gnunet-publish

Gui

1. In primis creiamo un pseudonimo che identificherà tutto cio che pubblichiamo
Ctrl-N o File sharing > Create pseudonym: nel mio caso harrykar(guarda shot  Screenshot-Publish content on GNUnet.png )

2. Poi Ctrl-A o File sharing > Publish : possiamo pubblicare un file o una dir di files:Nella dialog window di scelta file una volta scelto il file/dir click su ok in basso a dx

3. sulla window "publish content on gnunet" scegliamo il file e ckick su edit.Adesso possiamo associare al file dei metadati e delle keywords. Una volta che abbiamo finito click su ok in basso a dx(guarda shot Screenshot-Screenshot.png.png)
Riguardo la sezione Options in basso a dx(che in primis si potrebbero lasciare i valori di default):

Priority, Expiration Year:   that priority is just for the local datastore, it means nothing until your datastore is full and it has to find something to erase. Same with the expiration, when inserting something new with priority P and the datastore is full, it will first erase anything that's expired, then it will start erasing things of priority < P, if that fails (everything in the datastore is current and more important) then the insert fails.

Notice:That priority has nothing to do with priority defined as the amount of trust that the sender node S is willing to risk for his request in the "Excess-based economic model for resource allocation in P2P networks" paper

Anonymity
in theory: anonymity controls the ratio between your own traffic and the traffic you route
In other words, it's how much cover traffic you'll wait for until sending a response to a request for this file. That is, if you want to send 100 bytes with anonymity 5, you have to wait until you have 400 bytes of other people's traffic to route - then you will be able to send your 100 bytes along with it

in practice: anonymity == 0 means that non-anonymous routing is used. anonymity != 0 means that anonymous routing is used.(that is the state of gnunet implementation)

Index file
Localmente(al peer) le informazioni circa il contenuto e metadati vengono immagazzinate in un DBase (mysql, sqLite3, postgres). Anzichè il contenuto(file/dir) vero e proprio è più efficiente immagazzinare un puntatore al acontenuto. Per default Index file è spuntato


4. click su execute e il file viene pubblicato

gnunet-unindex

(sostituisce gnunet-delete nelle rel. precedenti)

Dopo aver pubblicato un file(Attenzione non funziona per le directory. Se abbiamo pubblicato una directory dobbiamo fare unindex ogni singolo file ivi contenuto) se dopo vogliamo "toglierlo dalla circolazione" e se il file è stato indicizzato(anzichè propriamente immagazinato) nel DB gnunet-unindex è il commando che interessa dare.

By default, GNUnet indexes a file instead of copying it. This is much more efficient, but requries the file to stay unaltered at the location where it was when it was indexed. If you intend to move, delete or alter a file, consider using the option -n which will force GNUnet to make a copy of the file in the database. Since it is much less efficient, this is strongly discouraged for large files. When GNUnet indexes a file (default), GNUnet does not create an additional encrypted copy of the file but just computes a summary (or index) of the file. That summary is approximately two percent of the size of the original file and is stored in GNUnet's database.

Whenever a request for a part of an indexed file reaches GNUnet, this part is encrypted on-demand and send out. There is no need for an additional encrypted copy of the file to stay anywhere on the drive. This is very different from other systems, such as Freenet where each file that is put online must be in Freenet's database in encrypted format, doubling the space requirements if the user wants to preseve a directly accessible copy in plaintext.

Thus indexing should be used for all files where the user will keep using this file (at the location given to gnunet-publish) and does not want to retrieve it back from GNUnet each time.
The option -n may be used if the user fears that the file might be found on his drive (assuming the computer comes under the control of an adversary). When used with the -n flag, the user has a much better chance of denying knowledge of the existence of the file, even if it is still (encrypted) on the drive and the adversary is able to crack the encryption (e.g. by guessing the keyword).

@LRN from #gnunet
Anyway, the point of GNUnet is NOT to hide your IP-address from everyone, but to make an adversary unable to determine whether a piece of data originated from your node or from somewhere else.THAT is what anonymity is about(and there's also deniability)

Subject:    Re: [Help-gnunet] HowTo for gnunet-stats?

At this point(Sun, 30 Nov 2003 14:57:12 -0500), most gnunet-stats numbers
are interesting for developers that look at a particular aspect of the system
only.  While end-users may find it useful for poking around, gnunet-stats is not
really targeted towards them.
