What CIDs can I provide?

I want to see what CIDs am I storing and what CIDs can I provide?

And I am aware of the DHT concept and how IPFS uses DHT.
So I want to see my local DHT.

Let’s say I get a request for a specific CID that I can provide info about. So where is this info stored? I want to see this info.

Can someone please help me with this.

Thanks alot I appreciate it!

If you want the list of blocks you’re storing, ipfs refs local will list them.

If you want the list of provider records you’re hosting, go-ipfs doesn’t provide command to access this information. You’d have to write some code.

Yes I want to see what CIDs I am storing.
Like I want to see what CIDs can my node provide.

I am willing to write some code.
Can you please help me out with that or atleast provide some pointers or directions to guide me.

Thank you.

Yes I want to see what CIDs I am storing.
Like I want to see what CIDs can my node provide.

Please be more specific.

  1. Data you have: Are you wondering which blocks (pieces of data) your node will provide over bitswap?
  2. Data you know about: Which pieces of content your node will help others find (provider records).

The provider logic lives in:

You’ll need to query the datastore for everything that starts with /providers/. See feat: .GetAllProviders func by daviddias · Pull Request #493 · libp2p/go-libp2p-kad-dht · GitHub for a past attempt at this.

Unfortunately, you’ll mostly be on your own here.

  1. Data you have: Are you wondering which blocks (pieces of data) your node will provide over bitswap?

I believe this can be done via this command: ipfs refs local
Is that correct?

  1. Data you know about: Which pieces of content your node will help others find (provider records).

Yes this is what I am looking for.
You know how each node has a table where they store information about CIDs and other peers, that is what I want to see.
For example: there is a specific CID that my node is storing, and then your node requests for that specific CID, and then my node will provide it.
So I want to see where is my node storing that CID along with other CIDs.
Does that make it clearer for you?

Thanks alot for your help I really appreciate it.

Yes. Those DHT links I posted should get you started there.
