# This a replacement Aikhjarto/block_badips.sh, using https://www.abuseipdb.com/ since badips.com seems to be offline :(
# This script downloads a list of IPs known for brute force attacking.
# The fetched IPs get blocked with iptables with the special comment "BADIP". This script only
# modifies iptables rules with that comment. This measure makes it well compatible with other firewall
# scripts like the SUSEFirewall.
# The iptables rules are updated every time this script is executed. Additionally this script is
# quiet on stdout, which makes it well suited for being executed as a cronjob.

This will autoconnect and disconnect mullvad on macOS based on white- and blacklisted wifi SSIDs

Make local binary directory if not existent:

mkdir -p ~/.local/bin

Get the script and make it executable:

wget -O ~/.local/bin/mullvad-wifi-connect-on-demand https://gist.githubusercontent.com/n-stone/d0388cfc3229435ff315a473d76686e6/raw/mullvad-wifi-connect-on-demand
chmod +x ~/.local/bin/mullvad-wifi-connect-on-demand

Keep custom Proxmox LXC template up to date

This script fully clones LXC 999 (Debian Based Container) to the storage named SSD-Storage starts it and installs updates. Afterwards it will dump a Backup to the storage named NAS mounted in /mnt/pve/NAS and copies it with a meaningfull name in the local template cache.

Every Sunday this script will archive a copy of the template and name it with the current date, the last 4 archived images will be kept.

If you want to reuse this script edit the storages, e.g. if you only have the local storage replace SSD-Storage and NAS with local, also replace /mnt/pve/NAS/dump/ with /var/lib/vz/. Also be sure to that ID 9876 is not taken and your custom template is ID 999, or replace the ID's accordingly.
