Scripts

General useful scripts (mostly for Linux)

dns_fetch.py


This lovely python script allows you to fetch ip address form cloudflare dns records. Useful for remote servers with dynamic ips. You can define the env file "dns_resolv_env.json" as follows:

{
        "auth_key": "key here",
        "zone_id": "zone id here",
        "default_name": "website name here"
}

Notes


  • The env file itself is optional but the script will require you to pass your auth key with --auth "key here"
  • If no zone id is provided the script will fetch and print from ALL zones on your cloudflare account.
  • If default_name is not specified by either file or via -n "name", filtering will be ignored

Usage Examples


  • python3 dns_fetch.py -a -n -i
    • Returns only the ip address of the A record corresponding to default_name.
      • This can be used in bash commands: ssh username@$(python3 dns_fetch.py -a -n -i)
  • python3 dns_fetch.py -a
    • Returns all A records
  • python3 dns_fetch.py -c
    • Returns all CNAME records
  • python3 dns_fetch.py
    • Prints the raw json from cloudflare
  • python3 dns_fetch.py -n
    • Prints all records corresponding to default_name
