I propose that the default 600s/10minute find time is a better test duration for this ban. The altered 120s findtime sounds reasonable until you consider that attackers can simply throttle to 3 attempts per minute and never be banned.
The remaining non default jail settings of maxretry = 7 and bantime = 3600 I believe are good.
Seems like ownCloud 8.1.1 now doesn't play nice with trusted_domains. Whatever is put in ahead of time gets reset to an array containing 'localhost' only, probably because we invoke autoconfiguration from the command line where it doesn't know the hostname it's being accessed from. We now set this value after running autoconfig.
This has the added benefit of also fixing the problem that if PRIMARY_HOSTNAME changes, trusted_domains wasn't updated. Now it is. Fixes#503.
See #514.
Nginx should be connecting over the local interface, not to the IP the resolver gives it. Elsewhere in this file proxy_pass uses 127.0.0.1 as it should.
Work-around for ownCloud 8.1.1 upgrade bug and tweaking munin's setup.
v0.13a (August 23, 2015)
------------------------
Note: v0.13 (no 'a', August 19, 2015) was pulled immediately due to an ownCloud bug that prevented upgrades. v0.13a works around that problem.
Mail:
* Outbound mail headers (the Recieved: header) are tweaked to possibly improve deliverability.
* Some MIME messages would hang Roundcube due to a missing package.
* The users permitted to send as an alias can now be different from where an alias forwards to.
DNS:
* The secondary nameservers option in the control panel now accepts more than one nameserver and a special xfr:IP format to specify zone-transfer-only IP addresses.
* A TLSA record is added for HTTPS for DNSSEC-aware clients that support it.
System:
* Backups can now be turned off, or stored in Amazon S3, through new control panel options.
* Munin was not working on machines confused about their hostname and had lots of errors related to PANGO, NTP peers and network interfaces that were not up.
* ownCloud updated to version 8.1.1 (with upgrade work-around), its memcached caching enabled.
* When upgrading, network checks like blocked port 25 are now skipped.
* Tweaks to the intrusion detection rules for IMAP.
* Mail-in-a-Box's setup is a lot quieter, hiding lots of irrelevant messages.
Control panel:
* SSL certificate checks were failing on OVH/OpenVZ servers due to missing /dev/stdin.
* Improve the sort order of the domains in the status checks.
* Some links in the control panel were only working in Chrome.
* let munin choose what it wants to monitor, it may need an update periodically
* deactivate monitoring of NTP peers (this makes no sense)
* deactivate monitoring of network interfaces that aren't up (also makes no sense)
* we get errors in munin-node.log if we don't create /var/lib/munin-node/plugin-state/
The antispam-plugin configuration is not ignoring deleted email (mail sent to a trash folder). This causes a big problem because if someone decides to "clean up" their Spam folder by deleting all of the emails, then sa-learn --ham is run on what is usually correctly caught spam messages. This causes big problems with the accuracy of the bayes scoring! It should really only be learning ham if someone drags the email to a non-Trash folder.
I ran "sa-learn --dbpath /home/user-data/mail/spamassassin --dump magic" before these changes and saw the nham counter increment with every message deleted from Spam. With this new config sa-learn --ham is not run when email is deleted from Spam so the bayes database is not incorrectly trained.
