- # cache-domains
-
- hotplug script 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
- The configuration file (`/etc/cache-domains.json`) 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_domains` 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_domains` 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": "server1",
- "blizzard": "server1",
- "origin": "server1",
- "steam": "server2",
- "wsus": "server3",
- "xboxlive": "server3"
- }
- }
- ```
-
- ## Configure/Cleanup
- `/usr/bin/cache-domains configure` will configure the local DNS (dnsmasq) to redirect the configured cache domains. `/usr/bin/cache-domains cleanup` will cleanup redirection. The hotplug script calls `/usr/bin/cache-domains configure` when the WAN interface is brought up.
-
- ## Testing
- After configuring with the above example configuration, running `nslookup lancache.steamcontent.com` would return `10.10.3.12`
