# $ Mikrotik RouterOS update script for CloudFlare $ # | |
# ================================================== # | |
# # | |
# - You need a CloudFlare account & api key (look under settings), # | |
# a zone and A record in it # | |
# - All variables in first section are obvious, except CFid, # | |
# To obtain CFzoneid use following command in any unix shell: # | |
# curl -X GET "https://api.cloudflare.com/client/v4/accounts" -H "X-Auth-Email: YOUR_EMAIL" -H "X-Auth-Key: YOUR_API_KEY" -H "Content-Type: application/json" | python -mjson.tool | |
# To obtain CFid use following command in any unix shell: # | |
# curl -X GET "https://api.cloudflare.com/client/v4/zones/YOUR_ZONE_ID/dns_records" -H "X-Auth-Email: YOUR_EMAIL" -H "X-Auth-Key: YOUR_API_KEY" -H "Content-Type: application/json" | python -mjson.tool | |
# - Enable CFDebug if needed - it'll print some info to logs # | |
# - Put script under /system scripts giving "read" policy access. # | |
# For 6.29 and older "test" policy is also needed. # | |
# - Add script to /system scheduler using it's name in "on-event" # | |
# - Requires at least RouterOS 6.44beta75 for multiple header support # | |
