Linode DNS Provider

This is a drop-in provider for apnscp to enable DNS support for accounts that use Linode. This provider is built into apnscp.

Configuring

EditDomain -c dns,provider=linode -c dns,key=abcdef1234567890 domain.com

Where the key is created within Linode. See Linode: API Key for information.

Setting as default

Linode may be configured as the default provider for all sites using the dns.default-provider Scope. When adding a site in Nexus or AddDomain the key will be replaced with "DEFAULT". This is substituted automatically on account creation.

In a multi-user environment, Keyring usage is necessary to protect users from accessing the password. When setting this value using the dns.default-provider-key in 3.2.42+, this value is automatically encoded as a Keyring value. Automatic wrapping as a Keyring object may be altered by changing [auth] => keyring_provider_types.

cpcmd scope:set dns.default-provider linode
# Note, this method is insecure prior to 3.2.42, see below!
cpcmd scope:set dns.default-provider-key 'abcdef1234567890'

::: warning Note that it is not safe to set this value directly in config.ini as a server-wide default in untrusted multiuser environments. A user with panel access can retrieve your key common_get_service_value dns key or even using Javascript in the panel, apnscp.cmd('common_get_service_value',['dns','key'], {async: false}).

Implicit Keyring encoding masks the actual value using a server secret. :::

Components

Module- overrides Dns_Module behavior
Validator- service validator, checks input with AddDomain/EditDomain helpers

Minimal module methods

All module methods can be overwritten. The following are the bare minimum that are overwritten for this DNS provider to work:

atomicUpdate() attempts a record modification, which must retain the original record if it fails
zoneAxfr() returns all DNS records
add_record() add a DNS record
remove_record() removes a DNS record
get_hosting_nameservers() returns nameservers for the DNS provider
add_zone_backend() creates DNS zone
remove_zone_backend() removes a DNS zone
