- DNS-Caching
- ===========
- User experience may be greatly improved when dns is accelerated. Also it
- seems like a good idea to keep the number if packages being exchanged
- between node and gateway as small as possible. In order to do this, a
- dns-cache may be used on a node. The dnsmasq instance listening on port
- 53 in the node will be re-configured to answer requests, use a list of
- upstream servers and a specific cache size if the below options are
- added to site.conf All settings are optional, though if no dns server is
- set, the configuration will not be altered by gluon-core.
- Besides caching dns requests from clients, the next_node-addresses are set to
- resolve to a configurable name that may optionally be placed in next_node.name.
- ::
- dns = {
- cacheentries = 5000,
- servers = { '2001:db8::1', },
- },
-
- next_node = {
- name = 'nextnode',
- ip6 = '2001:db8:8::1',
- ip4 = '198.51.100.1',
- }
- The cache will be initialized during startup. Each cache entry will use roughly
- 90 Bytes of main memory.
