Miscellaneous scripts for system admin

cfddnsv6.sh

This script updates CloudFlare IPv6 DNS records with your current IP address, as pulled from the interface directly. Best use case is having an ISP who arbitrarily changes your prefix. For safety, we do not create records, we only update records that match the hostname in the zone, so you must log in to CloudFlare and create your records first! Right now we run this from cron--- at reboot and every so often after. This example runs it at reboot and every half hour, adjust to taste.

@reboot /usr/local/bin/cfddnsv6.sh >/dev/null 2>&1

QUICK INSTALL:

sudo wget -O /usr/local/bin/cfddnsv6.sh https://raw.githubusercontent.com/Point808/debuntu-toolkit/master/cfddnsv6.sh; sudo chmod +x /usr/local/bin/cfddnsv6.sh

cleanup.sh

Quick and dirty script to clear disk space (log files, apt cache, etc etc) - useful if creating a machine template.
