Root cause of these and others is an ongoing DDoS of RuleQA, coming mostly from Huawei Cloud IPs hitting ruleqa.cgi with stupid queries. Possibly AI crawlers. There were some 'Require not ip' entries in the .htaccess for the worst offenders, but doing that at the HTTP level was still too rough on the machine, so I've inserted the lot at the top of the INPUT chain in iptables. I have also reduced the TCP close/fin/time wait times to clear out dead sessions faster.

Both of these are ephemeral changes which will go away at reboot, which is fine as they are easy to redo if we still need them after the next reboot, i.e. if the bots have given up.

Load avg. is now below 1.0.
