Simple DDNS utility with Alibaba Cloud (Aliyun) SDK

1. Create .ddns_config file in home directory, with following content:

{
	"access_key_id" : "<AccessKey ID>",
	"access_key_secret" : "<AccessKey Secret>",
	"connect_timeout" : 1500,
	"read_timeout" : 4000,
	"domain_name" : "ddns4.domain.com,ipv4.domain.com",
	"domain_name_v6" : "ddns6.domain.com,ipv6.domain.com",
	"query_ipv4" : "https://api.ipify.org",
	"query_ipv6" : "https://api6.ipify.org"
}

• access_key_id: Aliyun AccessKey ID
• access_key_secret: Aliyun AccessKey Secret
• connect_timeout (optional): Aliyun SDK connection timeout in ms
• read_timeout (optional): Aliyun SDK read timeout in ms
• domain_name: Domain name to update A record
• query_ipv4: URL to query current public IPv4 address, this URL should return IPv4 plain text!!!
• domain_name_v6: (optional) Domain name to update AAAA record
• query_ipv6: (optional if domain_name_v6 does not exist) URL to query current public IPv6 address, this URL should return IPv6 plain text, and it should only have AAAA domain record!!!

2. Simply run this to check and update domain record if needed:

$ aliddns
Old IPv4:     (ddns4.domain.com)[1.2.3.4]
Current IPv4: (ddns4.domain.com)[1.1.1.1]
Updated:      (ddns4.domain.com)[1.1.1.1]
Old IPv4:     (ipv4.domain.com)[1.1.1.1]
Current IPv4: (ipv4.domain.com)[1.1.1.1]
Skipped:      (ipv4.domain.com)[1.1.1.1]
Old IPv6:     (ddns6.domain.com)[a55a:a55a:a55a:a55a:a55a:a55a:a55a:1]
Current IPv6: (ddns6.domain.com)[a55a:a55a:a55a:a55a:a55a:a55a:a55a:a55a]
Updated:      (ddns6.domain.com)[a55a:a55a:a55a:a55a:a55a:a55a:a55a:a55a]
Old IPv6:     (ipv6.domain.com)[a55a:a55a:a55a:a55a:a55a:a55a:a55a:a55a]
Current IPv6: (ipv6.domain.com)[a55a:a55a:a55a:a55a:a55a:a55a:a55a:a55a]
Skipped:      (ipv6.domain.com)[a55a:a55a:a55a:a55a:a55a:a55a:a55a:a55a]
