- firewall.php: auto-detect server IPs (loopback, all interface IPs,
private /24 subnets) for Fail2Ban ignoreip; f2b-ignoreip-list/add/
remove/reset actions; write to jail.local directly (www-data owns it);
f2b_set_ignoreip() reloads fail2ban after every change
- auth.php: log failed logins to /var/log/novacpx/access.log in format
fail2ban filters expect — "FAILED LOGIN from <IP> [portal]"
- deploy/fail2ban/: filter.d conf files for all 4 NovaCPX jails
- install.sh: auto-detect local IPs → ignoreip in jail.local; install
filter files; create access.log (www-data:www-data 664)
- admin.js: Fail2Ban Whitelist section in firewall page — chip list with
add/remove/reset; loopback shown with lock icon and non-removable
