# meshname
<img src="https://raw.githubusercontent.com/zhoreeq/meshname/master/img/logo-medium.png">
A universal naming system for all IPv6-based mesh networks, including CJDNS and Yggdrasil.
Implements the [Meshname protocol](https://github.com/zhoreeq/meshname/blob/master/protocol.md).
## F.A.Q.
- Q: *Is it like a decentralized DNS thing?*
- A: Yeah, sort of. With it you can host your own meshname domains and resolve domains of others.
- Q: *Meshname domains are ugly.*
- A: Yes, if you want decentralization, you either have ugly names or a blockchain. Meshname has ugly names, but it works at least!
## How to install and use
Minimum go version 1.12 is required.
1) Get the source code and compile
```
git clone https://github.com/zhoreeq/meshname.git
cd meshname
make
```
2) Generate the default config for your host
```
./meshnamed -genconf 200:6fc8:9220:f400:5cc2:305a:4ac6:967e -subdomain meshname | tee /tmp/meshnamed.conf
```
3) Run the daemon
```
./meshnamed -useconffile /tmp/meshnamed.conf
```
4) Optionally, set configuration flags
```
./meshnamed -listenaddr [::1]:53535 -debug -useconffile /tmp/meshnamed.conf
```
5) See the list of all configuration flags
```
./meshnamed -help
```
Add custom DNS records to the configuration file and restart the daemon to apply settings.
A DNS record can be of any valid string form parsed by [miekg/dns#NewRR](https://godoc.org/github.com/miekg/dns#NewRR) function (see example configuration file below).
## systemd unit
Look for `meshnamed.service` in the source directory for a systemd unit file.
## Example configuration file
In this example, meshnamed is configured as authoritative server for two domain zones:
{
"aiag7sesed2aaxgcgbnevruwpy": [
"aiag7sesed2aaxgcgbnevruwpy.meshname. AAAA 200:6fc8:9220:f400:5cc2:305a:4ac6:967e",
"_xmpp-client._tcp.aiag7sesed2aaxgcgbnevruwpy.meshname. SRV 5 0 5222 xmpp.aiag7sesed2aaxgcgbnevruwpy.meshname",
"_xmpp-server._tcp.aiag7sesed2aaxgcgbnevruwpy.meshname. SRV 5 0 5269 xmpp.aiag7sesed2aaxgcgbnevruwpy.meshname",
"xmpp.aiag7sesed2aaxgcgbnevruwpy.meshname. AAAA 300:6fc8:9220:f400::1",
"forum.aiag7sesed2aaxgcgbnevruwpy.meshname. CNAME amag7sesed2aaaaaaaaaaaaaau.meshname."
],
"amag7sesed2aaaaaaaaaaaaaau": [
"amag7sesed2aaaaaaaaaaaaaau.meshname. AAAA 300:6fc8:9220:f400::5"
]
}
## Configure dnsmasq as a primary DNS resolver with "meshname." support
`/etc/dnsmasq.conf`
port=53
domain-needed
bogus-priv
server=/meshname/::1#53535
server=8.8.8.8
## Using meshnamed as a standalone DNS server
Set the flag to listen on all interfaces and a standard DNS server port
./meshnamed -listenaddr [::]:53 -useconffile /tmp/meshnamed.conf
Run as root and allow incoming connections to port 53/UDP in firewall settings.
## Custom top level domains (TLD) and subnet filtering
meshnamed can be configured to resolve custom TLDs.
To run meshnamed for TLD `.newmesh` with addresses in `fd00::/8`
set a flag `-networks newmesh=fd00::/8`.
By default, in addition to `.meshname` it also resolves `.ygg` for IPv6 addresses in
`200::/7` subnet and `.cjd` for `fc00::/8`.
Requests are filtered by subnet validation. Request is ignored if a decoded
IPv6 address doesn't match the specified subnet for a TLD.
