# cache-domains
|
||
|
|
|
||
|
|
Service to dynamically configure the local DNS (dnsmasq) to redirect game content servers to a LAN cache. Definitive list dynamically obtained from https://github.com/uklans/cache-domains.
|
||
|
|
|
||
|
|
## Configuration
|
||
|
|
Configuration file follows the same [syntax as the upsteam file](https://github.com/uklans/cache-domains/blob/master/scripts/config.example.json). The key for each `cache_domain` member matches the name of one of the `.txt` files in the [upstream root directory](https://github.com/uklans/cache-domains/blob/master/), except for the `default` key which matches the all the unreferenced `.txt` files. The value of each `cache_domain` member maps to one of the keys of the `ips` members, Thus mapping a cached domain to a list of IP addresses/LAN cache server.

|
|
|
||
|
|
```json
|
||
|
|
{
|
||
|
|
"ips": {
|
||
|
|
"server1": ["10.10.3.10", "10.10.3.11"],
|
||
|
|
"server2": "10.10.3.12",
|
||
|
|
"server3": "10.10.3.13"
|
||
|
|
},
|
||
|
|
"cache_domains": {
|
||
|
|
"default": "server2",
|
||
|
|
"blizzard": "server1",
|
||
|
|
"origin": "server1",
|
||
|
|
"steam": "server1",
|
||
|
|
"wsus": "server3",
|
||
|
|
"xboxlive": "server3"
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## Startup/Shutdown
|
||
|
|
On start the local DNS (dnsmasq) will be configured to redirect the configured cache domains and on stop the redirection will be removed.
|
||
|
|
|
||
|
|
## Testing
|
||
|
|
With the above configuration set and the service running `nslookup swcdn.apple.com` would return `10.10.3.12`
