Re: issue with connecting two local peers

[gogo gogo]

Could you either document the second method or can you give me the instruction to do it manually please?

There are two ways of doing this in gnunet.

The first is to do it manually, by starting two peers with different configurations and having them connect.

But the proper way to do testing would be to use the (new) testing API.

Alas, there is no usable documentation for either right now.

If you wish to start multiple peers on one machine, you probably need to adjust the configuration more.

 

• If things are still the same as when I last worked with this (and IIRC), some things are _outside_ GNUNET_HOME. There are some sockets … somewhere (I think under /tmp? Not sure where.). So, GNUnet might be getting confused from this.
• Maybe wait a few seconds after doing ‘gnunet-arm […] -s’, instead of the &&. Maybe the TCP or UDP transports haven’t choosen a port yet? I’m not sure this is how it works though – not familiar with this, this is speculation.
• I’m not sure if UDP ports are choosen automatically. If they aren’t, then there might be some kind of port conflic. In case of UDP (unidirectional), then the peers would be unable to verify each others existence.
• Even if they are choosen automatically, this automation probably had NAT-punching in mind, not this.
• For an isolated network, I think you also need to tell GNUnet to bind to ‘localhost’ instead of everything.

 

It would be nice to have official documentation on setting up this kind isolated one-machine, multiple peers network. It seems quite convenient for safely testing things out. (Though for full isolation, a ‘unix’ transport would be needed.)
