scusate l'ot ragazzi (chiamo in primis @Dr. Gori), qualcuno di voi è iscitto su pc-facile?

No
Cos'è, un forum generalista sui pc?

No
Cos'è, un forum generalista sui pc?

PC, telefonia e informatica in generale. Ci sono utenti veramente moooooolto preparati che mi hanno aiutato a risolvere diversi problemi.
Chiedevo perché una settimana fa mi son loggato per modificare le mie impostazioni, ma non riesco più ad accedere. Ho mandato decine di mail, ma nessuno risponde. Sono iscritto da 15 anni. Boh.

Pgp web of trust

  

The key needs to be verified. If you trust that someone's public key does in fact belong to that individual and they are in your keyring you can use your private key to sign your correspondent's public key and validate it.

So you are Bob and you trust that Alice's public key does in fact belong to Alice, so you sign it with your private key. So Alice's key is trusted to you. Also any keys that Alice trusts, say someone called Chris will be in your web of trust also. So you can also trust Chris, because Alice does. So Chris’s key will be certified with a trusted signature.

Now if Alice trusts that your key does belong to you then she can validate your public key with by signing it with her private key, therefore your key will now be included in that same web of trust.

a procedure was given to validate your correspondents' public keys: a correspondent's key is validated by personally checking his key's fingerprint and then signing his public key with your private key. By personally checking the fingerprint you can be sure that the key really does belong to him, and since you have signed they key, you can be sure to detect any tampering with it in the future. Unfortunately, this procedure is awkward when either you must validate a large number of keys or communicate with people whom you do not know personally.

GnuPG addresses this problem with a mechanism popularly known as the web of trust. In the web of trust model, responsibility for validating public keys is delegated to people you trust. For example, suppose

Alice has signed Blake's key, and

Blake has signed Chloe's key and Dharma's key.

If Alice trusts Blake to properly validate keys that he signs, then Alice can infer that Chloe's and Dharma's keys are valid without having to personally check them. She simply uses her validated copy of Blake's public key to check that Blake's signatures on Chloe's and Dharma's are good. In general, assuming that Alice fully trusts everybody to properly validate keys they sign, then any key signed by a valid key is also considered valid. The root is Alice's key, which is axiomatically assumed to be valid. Trust in a key's owner

In practice trust is subjective. For example, Blake's key is valid to Alice since she signed it, but she may not trust Blake to properly validate keys that he signs. In that case, she would not take Chloe's and Dharma's key as valid based on Blake's signatures alone. The web of trust model accounts for this by associating with each public key on your keyring an indication of how much you trust the key's owner.

There are four trust levels.

unknown

Nothing is known about the owner's judgement in key signing. Keys on your public keyring that you do not own initially have this trust level.

none

The owner is known to improperly sign other keys.

marginal

The owner understands the implications of key signing and properly validates keys before signing them.

full

The owner has an excellent understanding of key signing, and his signature on a key would be as good as your own.

A key's trust level is something that you alone assign to the key, and it is considered private information. It is not packaged with the key when it is exported; it is even stored separately from your keyrings in a separate database. The GnuPG key editor may be used to adjust your trust in a key's owner.

Controllare i componenti della scheda madre

Lo strumento che bisogna possedere e saper usare per riparare la scheda madre di un computer è il tester. Come prima cosa effettuate un'analisi visiva, per verificare se qualche componente è bruciato. Se siete fortunati e la scheda madre non parte per questo motivo, allora sarà sufficiente dissaldare il componente bruciato e sostituirlo con uno nuovo. In caso contrario, è necessario controllare i singoli componenti, per assicurarsi che siano correttamente saldati, infatti un componente dissaldato potrebbe aver causato l'anomalia e quindi i problemi riscontrati nella scheda madre. Se anche dopo questa verifica non avrete riscontrato anomalie, procedete nel controllo della batteria del CMOS: alcune "motherboard" non partono se questa è scarica.
