roles/common: minor configuration of Debian 13 SSH

Tweak some of the new OpenSSH per-source penalty settings on Debian 13. For now only adjusting the source network masks and reusing the list of IPs to exempt from fail2ban. These being built in makes them easier to use, but I think I will end up sticking with fail2ban for the heavy lifting because it per- sists across restarts of the daemon, whereas OpenSSH's doesn't. I will monitor OpenSSH on Debian 13 to see how to best use it along side fail2ban.
roles/common: use 127.0.0.0/8 for fail2ban ignoreip

Alan Orth	d51f8fefaa	roles/common: minor configuration of Debian 13 SSH Tweak some of the new OpenSSH per-source penalty settings on Debian 13. For now only adjusting the source network masks and reusing the list of IPs to exempt from fail2ban. These being built in makes them easier to use, but I think I will end up sticking with fail2ban for the heavy lifting because it per- sists across restarts of the daemon, whereas OpenSSH's doesn't. I will monitor OpenSSH on Debian 13 to see how to best use it along side fail2ban.	2025-09-23 10:33:24 +03:00
Alan Orth	9ff6e19135	roles/common: use 127.0.0.0/8 for fail2ban ignoreip We can re-use our fail2ban ignoreip setting for Debian 13's OpenSSH PerSourcePenaltyExemptList, but OpenSSH is more strict with regards to masks not being applied to the host portion. I had never noticed that fail2ban's default was applying the mask on the host portion!	2025-09-23 10:33:23 +03:00

Alan Orth	00558c7dea	roles/common: re-work fail2ban and nftables Re-work the fail2ban and nftables interaction. Use systemd's PartOf to indicate that fail2ban is part of the nftables service, which tells systemd to propogate stop/start signals to it. Then we tell the firehol update script to restart nftables instead of reload. The different between restart and reload is meaningless for nftables but we want systemd to propagate the stop/start signals to fail2ban.	2025-07-08 10:39:17 +03:00
Alan Orth	c927186837	roles/common: adjust update-firehol-nftables.service This service does not actually depend on nftables, at least not in the systemd sense of dependency.

Alan Orth	cb79f7ef70	roles/common: minor change to firehol update script They include bogons like 127.0.0.1 that should not be routed on the public Internet, but this blocks local applications we proxy to.	2025-01-28 09:14:48 +03:00
Alan Orth	bb14f05d2a	roles/common: use Ansible timezone module No need to use a command for that. The module does it better because it doesn't register a change unless the timezone changes.	2025-01-27 23:11:56 +03:00

Alan Orth	7a9a24ef5d	roles/common: rework fail2ban again Actually, we do want to run fail2ban on all hosts because the sshd monitoring via systemd is nice. At the very least it reduces spam from failed logins in our systemd journal.	2023-08-23 22:15:24 +03:00
Alan Orth	067adcd9f5	roles/common: rework fail2ban tasks We can only run fail2ban when we have logs to monitor. When a host is running Caddy we don't have logs, so fail2ban doesn't have any- thing to monitor out of the box. For now I will restrict the task to hosts running nginx.	2023-08-23 21:59:28 +03:00
