The one-liner:

dd if=/dev/zero bs=1G count=10 | gzip -c > 10GB.gz

This is brilliant.

    Setting a random SSH port and limiting it to 3/min saw failed login attempts fall by 99% and jailed IPs fall to 0.

      I’ve found great success using a hardened ssh config with a limited set of supported Cyphers/MACs/KexAlgorithms. Nothing ever gets far enough to even trigger fail2ban. Then of course it’s key only login from there.
