meshname

Special-use naming system for self-organized IPv6 mesh networks. Implements Meshname protocol.

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
  1. Generate the default config for your host
./meshnamed -genconf 200:6fc8:9220:f400:5cc2:305a:4ac6:967e -subdomain meshname | tee /tmp/meshnamed.conf
  1. Run the daemon
./meshnamed -useconffile /tmp/meshnamed.conf
  1. Optionally, set configuration flags
./meshnamed -listenaddr [::1]:53535 -debug -useconffile /tmp/meshnamed.conf
  1. See list of all configuration flags
./meshnamed -help

Add new DNS records to configuration file and restart the daemon to apply settings. A record can be of any valid string form parsed by miekg/dns.

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 for two domain zones:

{
        "Domain":"aiag7sesed2aaxgcgbnevruwpy",
        "Records": [
                "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."
        ]
}
{
        "Domain":"amag7sesed2aaaaaaaaaaaaaau",
        "Records":[
                "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.
