Run a relay
We currently only support running relays using the CLI version. Relays should be run on machines with public IP addresses.
Relays and clients nodes use the same earendil
executable. The defining difference is in their config file: relay configs have a relay_config
section that specifies identity_file
(to store the relay's long-term identity) and in_routes
(where and how to accept incoming connections), while client configs do not.
To run a relay, save this config file into a file named relay-cfg.yaml
. Be sure to replace "/your/path/` with an appropriate path:
# neighbors, same as in client config
out_routes:
example-relay-free:
connect: 62.210.93.59:12345
fingerprint: 4b7a641b77c2d6ceb8b3fecec2b2978dfe81ae045ed9a25ed78b828009c4967a
obfs:
sosistab3: "randomly-generated-cookie-lala-doodoo"
price_config:
inbound_price: 0
inbound_debt_limit: 0
outbound_max_price: 0
outbound_min_debt_limit: 0
# relay-only settings
relay_config:
# replace with a writable path for storing identity secret
identity_file: /your/path/earendil-relay-id.secret
in_routes:
main_udp:
obfs:
# random seed for obfsudp cookie. Generate your own with `earendil generate-seed`
sosistab3: <your_random_seed>
# port where this in-route listens
listen: 0.0.0.0:19999
# price, debt limit etc. for this in-route
price_config:
inbound_price: 0
inbound_debt_limit: 0
outbound_max_price: 0
outbound_min_debt_limit: 0
You can learn about paying and getting paid on the Earendil network, as well as the price_config
here.
Start the earendil
daemon using this relay config:
earendil daemon --config relay-cfg.yaml
While the earendil
daemon is running, obtain your relay's contact information for other nodes to connect with you as a neighbor with the control command my-routes
:
earendil control my-routes
The output should look like:
main_udp:
connect: <YOUR_IP>:19999
fingerprint: 57a407e50c1f4d0cdfb16332f6a836b27cc3409941fa26d85bc2b1eca604e536
obfs:
sosistab3: <your_random_seed>
price_config:
inbound_price: 0
inbound_debt_limit: 0
outbound_max_price: 0
outbound_min_debt_limit: 0
Replace <YOUR_IP>
with your server's public IP address. Other nodes (both clients and relays) can simply paste this block into the out_routes
section of their config file to add your relay as a neighbor.
To serve users in regions with internet censorship, you should avoid posting your relay's contact information publicly. Instead, distribute it in a way that reaches legitimate users but not censors--your relay will be blacklisted if the censor learns its IP address!
