# DDDNS
A dynamic DNS system using libp2p. Uses a rendezvous point in the DHT to find the target peer.
The public IP of the node is obtained from the multiaddress array provided from libp2p, or from third party services as a fallback.
Each node in the network has an ID in the base32 form of it's public key, such as:
`baareie5g66lu3ney2e4qfs2x3webynbaeoojkjxnd6dm36daas5k73vba`
When running as a daemon, it can act as a DNS proxy, resolving domains with the "dddns" TLD, with the form:
`baareie5g66lu3ney2e4qfs2x3webynbaeoojkjxnd6dm36daas5k73vba.dddns`
and forwarding the rest to an upstream DNS server.
## Build
To build:
`go build ./cmd/dddns/dddns.go`
With docker compose:
`docker-compose build`
## Usage
```
NAME:
dddns - A dynamic and distributed DNS system.
USAGE:
dddns [global options] command [command options] [arguments...]
VERSION:
0.1
COMMANDS:
help, h Shows a list of commands or help for one command
client:
client Starts DDDNS in client mode
daemon:
daemon Starts DDDNS in daemon mode
GLOBAL OPTIONS:
--bootstrap-node value The address a of bootstrap node. DDDNS will connect for peer discovery via DHT. Will use IPFS ones by default
--datadir value Path to store the data. (default: "/home/vdo/.dddns")
--port value Port used to listening and respond requests. (default: 44453)
--protid value The ID of the protocol. (default: "/dddns/1.0.0")
--loglevel value Log level of the output [debug,info,warn,error] (default: "info")
--help, -h show help
--version, -v print the version
```
To run as a daemon:
`./dddns daemon [--dnsenable]`
To run as client:
`./dddns client --pubkey baareie5g66lu3ney2e4qfs2x3webynbaeoojkjxnd6dm36daas5k73vba`
If you are running the deamon locally, it can act as a proxy adding the following line at the top of `/etc/resolv.conf` :
`nameserver 127.0.0.1`
then, you should be able to resolve .dddns hosts like the example:
```
$ dig @localhost baareie5g66lu3ney2e4qfs2x3webynbaeoojkjxnd6dm36daas5k73vba.dddns +short
108.61.209.8
```
## Notes
In order to run the nameserver daemon a normal user, you need to add capabilities to bind the DNS port (53):
`sudo setcap CAP_NET_BIND_SERVICE=+eip dddns`
## To-Do
- [ ] Tests!
- [ ] IPv6 support
- [ ] Improve forwarding (only A now)
- [ ] Use a simple PubSub system, like [subpub](https://gitlab.com/vocdoni/go-dvote/-/blob/master/subpub/subpub.go)
- [ ] Add [cache](https://github.com/patrickmn/go-cache) for faster resolution
- [ ] Add a wrapper script to use alternative resolution [(bubblewrap)](https://wiki.archlinux.org/index.php/Bubblewrap)
