* Fix the catch-all resolution again.Guilhem Moulin2015-06-071
| | | | | | | | | | | | | | | | | | | | We introduce a limitation on the domain-aliases: they can't have children (e.g., lists or users) any longer. The whole alias resolution, including catch-alls and domain aliases, is now done in 'virtual_alias_maps'. We stop the resolution by returning a dummy alias A -> A for mailboxes, before trying the catch-all maps. We're still using transport_maps for lists. If it turns out to be a bottleneck due to the high-latency coming from LDAP maps, (and the fact that there is a single qmgr(8) daemon), we could rewrite lists to a dummy subdomain and use a static transport_maps instead: virtual_alias_maps: mylist@example.org -> mylist#example.org@mlmmj.localhost.localdomain transport_maps: mlmmj.localhost.localdomain mlmmj:

| | | | | | | | | Right now the list server cannot be hosted with a MX, due to bug 51: http://mlmmj.org/bugs/bug.php?id=51 Web archive can be compiled with MHonArc, but the web server configuration is not there yet.

* Fix catchall resolution.Guilhem Moulin2015-06-071
| | | | | | | | It has to be performed last, to give a chance to be accepted as a regular mailbox. We introduce a new, dedicated, smtpd daemon whose only purpose is to resolve catch-alls.

* Configure NTP.Guilhem Moulin2015-06-075
| | | | | | We use a "master" NTP server, which synchronizes against stratum 1 servers (hence is a stratum 2 itself); all other clients synchronize to this master server through IPSec.

* Share master.cf accross all Postfix instances.Guilhem Moulin2015-06-073
| | | | | | And use main.cf's 'master_service_disable' setting to deactivate each service that's useless for a given instance. (Hence solve conflict when trying to listen twice on the same port, for instance.)
* Use a dedicated SMTP port for samhain.Guilhem Moulin2015-06-074
| | | | | | | It's unfortunate that samhain cannot use the sendmail binary, and wants to use a inet socket instead. We use a custom port to avoid conflicts with the usual SMTP port the MX:es need to listen on. See also: /usr/share/doc/samhain/TODO.Debian

* Optimize LDAP modifications.Guilhem Moulin2015-06-071
| | | | | | | For non-indexed attributes, do not ask the LDAP server to modify values in the symmetric difference of A (the entry found in the directory) and B (the target). That is, we replace A by B only when they are disjoint; otherwise we remove values in A-B and add those in B-A.

| | | | | To be clearer, and to follow the recommendation of the FSF, we include a full header rather than a single sentence.

* Replace the 'syslog' facility (5) by 'user' (1).Guilhem Moulin2015-06-072
| | | | | 'syslog' is meant for the messages generated internally by syslogd, whereas 'user' is for user-level messages.

* Be more specific regarding the protocol in use for IPSec policies.Guilhem Moulin2015-06-073
| | | | We use ESP only, so other protocols shouldn't be ACCEPTed.
* Don't start daemons when there is a triggered handler.Guilhem Moulin2015-06-074
| | | | This is pointless since the service will be restarted anyway.
* Flush pending handlers between each include.Guilhem Moulin2015-06-076
| | | | | | | | | In particular, run 'apt-get update' right after configured APT, and restart daemon right after configured them. The advantage being that if ansible crashes in some "task", the earlier would already be restarted if neeeded. (This may not happen in the next run since the configuration should already be up to date.)

* Prohibit binding against the IP reserved for IPSec.Guilhem Moulin2015-06-073
| | | | | | | | | Packets originating from our (non-routable) $ipsec are marked; there is no xfrm lookup (i.e., no matching IPSec association), the packet will retain its mark and be null routed later on, thanks to ip rule add fwmark "$secmark" table 666 priority 666 ip route add blackhole default table 666
* Prefer maching on policy rather than marks.Guilhem Moulin2015-06-072
| | | | Also, use ESP tunnel mode instead of transport mode.
* Preserve canonical the order of IP tables.Guilhem Moulin2015-06-071
| | | | I.e., as packets are treated along the way: mangle -> nat -> filter.

* Use a dedicated, non-routable, IPv4 for IPSec.Guilhem Moulin2015-06-076
| | | | | | | At the each IPSec end-point the traffic is DNAT'ed to / MASQUERADE'd from our dedicated IP after ESP decapsulation. Also, some IP tables ensure that alien (not coming from / going to the tunnel end-point) is dropped.
* Major refactoring of the firewall.Guilhem Moulin2015-06-072
| | | | | | | | | | Also, added some options: -f force: no confirmation asked -c check: check (dry-run) mode -v verbose: see the difference between old and new ruleset -4 IPv4 only -6 IPv6 only
* Don't save dynamic rules.Guilhem Moulin2015-06-073
| | | | | These rules are automatically included by third-party servers such as strongSwan or fail2ban.
* Use a dedicated 'fail2ban' chain for fail2ban.Guilhem Moulin2015-06-072
| | | | So it doesn't mess with the high-priority rules regarding IPSec.
* Add a 'check' switch to the firewall.Guilhem Moulin2015-06-072
| | | | | update-firewall.sh -c does not update the firewall, but returns a non-zero value iff. running it without the switch would modify it.
* Configure the (basic) logging policy.Guilhem Moulin2015-06-075
