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 (required without --auth)",
        "zone_id": "zone id here (optional)",
        "default_name": "website name here (optional)"
}

The script has many useful featues:

• python3 dns_fetch.py -a -n -i which will return 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 will return all A records
• python3 dns_fetch.py -c will return all CNAME records
• python3 dns_fetch.py will print the raw json from cloudflare
• python3 dns_fetch.py -n will print all records corresponding to default_name
