Example of Full Mesh Typology. #205

Closed ndo360 closed 4 years ago

ndo360 commented 4 years ago

Greetings!

I am presently struggling on figuring out how to configure a full mesh typology with FreeLAN. All the examples provided, at least from what I have seen, have suggested more of a 'Client / Server' approach. What am I missing, and how can I configure a full mesh. Could someone kindly provide an example between three nodes?

Cheers, Noah C. Cline

Hello! freelan supports Peer-to-Peer connect (not torrent connection) which means, useful data can go from one white ip to another.

One of the peers , the one with White IP maybe need as a point of metadata exchange for Dynamic contacts. Dynamic Contact needed if your client machines behind NAT.

But as a whole freelan supports Hybrid topology. There were sort of Metatada server (https://github.com/freelan-developers/freelan-server) in freelan1.1 but they removed it due to license issues. I hope Developers of Freelan will revive it

Thanks for the reply, please forgive my ignorance, but does this mean that a full mesh network isn't possible?

The reason I ask is the site says it should be supported, and the diagram it shows gives the impression that there wouldn't be a single point of failure.

The ports can be forwarded for all clients if that resolves NAT problems, just trying to make sure I understand. Apologies for my ignorance on this, first time trying to do something involving this program.

P.S. White IP... Is that the one that starts the network? Has connection to the internet with ports forwarded?

Also, apoligies if I have misused the term 'full mesh'. I was trying to ask how to create the P2P network that doesn't have a single point of failure.

freelan can make full-mesh for data traffic WITHOUT port forwarding. I've tested this part. However you need a server for meta-data.

In my installation I had:

I need network backup, and freelan was a perfect solution. 👍 backups were flowing at speed 40-50 mbits between clients. One of clients was a storage.

richman1000000 commented 4 years ago

unfortunately freelan doesn't support distributed hash table (DHT)

ndo360 commented 4 years ago

So there would always be a single point of failure then? As I presume meta-data must be resolved for the network to function.

richman1000000 commented 4 years ago

not exactly. Any peer with WhiteIP can accept meta-data request and forward them, thus anyone with WhiteIP can become a server. This is done manually currently (you have to posted you IP info somewhere) But DHT just automates this part, I think.

ndo360 commented 4 years ago

Could FreeLAN support multiple 'White IPs?' (Tinc has a similar system, but the mesh keeps track of the hosts and can tell who is portforwarxed and able to transfer meta-data.)

richman1000000 commented 4 years ago

yes, it is

ndo360 commented 4 years ago

Could you write an example where this is possible?

ndo360 commented 4 years ago

Okay after reading the config file more closely, I noticed that there is a method to get users contact information. (You have to use certificates, accept contacts, and the sort.)

My one question now is the 'dynamic_contact_file' by default is empty. If it's empty, will a list of contacts still be compiled, if not how would I specify a file? Cheers!
