      TID: Mystic BBS 1.12 A49       MSGID: 2:250/5 71729cb9       REPLY: 1:266/625 78a8d8fb       TZUTC: 0100       On 01 Jul 2024, Scott Street said the following...                SS> So the basic flow of this process.        SS> 1) MIS decides to block a given IP because it violates the connection        SS> attempt rules set in the individual server configuration table.        SS> 2) MIS executes the "IP Blocked" event, which adds the IP to the list        SS> 3) Every 5 mins, the cron job runs and adds all the queued IPs to the        SS> iptables input filter, and after the new list of IPs have been added,        SS> makes them persistent across restarts with netfilter-persistent.        SS>         SS> You can track the activity of this process using your system log -        SS> journalctl for me, I'm on Debian 12 (bookworm).         SS>         SS> I hope you find this useful, especially those of you running some        SS> flavor of Linux.

Then you have iptables       blocking you out and you won't be able to get back in =)              Can you modify that to only block on the ports you have for telnet/ssh to the       BBS (assuming SSH to the bbs is different to SSH to the cli).              ...
