Two-node Networking

Assuming the network topology of the two nodes is as follows

flowchart LR

subgraph Node A IP 22.1.1.1
nodea[EasyTier\n10.144.144.1]
end

subgraph Node B
nodeb[EasyTier\n10.144.144.2]
end

nodea <-----> nodeb

1. Execute on Node A:

   sudo easytier-core --ipv4 10.144.144.1
   

   Successful execution of the command will print the following.

   $ easytier-core --ipv4 10.144.144.1
   Starting easytier with config:
   ############### TOML ##############
   
   instance_name = "default"
   instance_id = "7294d13c-d119-49ae-a5f7-8c3a912538d7"
   ipv4 = "10.144.144.1"
   listeners = [
       "tcp://0.0.0.0:11010",
       "udp://0.0.0.0:11010",
       "wg://0.0.0.0:11011",
   ]
   peer = []
   rpc_portal = "127.0.0.1:15888"
   
   [network_identity]
   network_name = "default"
   network_secret = ""
   
   [flags]
   default_protocol = "tcp"
   enable_encryption = true
   enable_ipv6 = true
   
   -----------------------------------
   xxxx-xx-xx xx:xx:xx: tun device ready. dev: tun0
   xxxx-xx-xx xx:xx:xx: new listener added. listener: tcp://0.0.0.0:11010
   xxxx-xx-xx xx:xx:xx: new listener added. listener: udp://0.0.0.0:11010
   

2. Execute on Node B

   sudo easytier-core --ipv4 10.144.144.2 --peers udp://22.1.1.1:11010
   

3. Test Connectivity

   The two nodes should connect successfully and be able to communicate within the virtual subnet

   ping 10.144.144.2
   

   Use easytier-cli to view node information in the subnet

   easytier-cli peer
   

   ipv4	hostname	cost	lat_ms	loss_rate	rx_bytes	tx_bytes	tunnel_proto	nat_type	id
   10.144.144.1	abc-dec	1	3.452	0	17.33kB	20.42kB	udp	FullCone	390879727

   Use easytier-cli to view routing information in the subnet

   easytier-cli route
   

   ipv4	hostname	proxy_cidrs	next_hop_ipv4	next_hop_hostname	next_hop_lat	cost
   10.144.144.1	abc-dec		DIRECT		3.646	1

   Use easytier-cli to view local node info.
