* Move /etc/ssl/private/dhparams.pem to /etc/ssl/dhparams.pem and make it public.Guilhem Moulin2016-05-181
| | | | | | | | | | Ideally we we should also increase the Diffie-Hellman group size from 2048-bit to 3072-bit, as per ENISA 2014 report. https://www.enisa.europa.eu/publications/algorithms-key-size-and-parameters-report-2014 But we postpone that for now until we are reasonably certain that older client won't be left out.

* genkeypair: use install(1) for atomic file creation with permission mode.Guilhem Moulin2015-10-282
|
* Use a single LDAP connection per Munin round to collect slapd statistics.Guilhem Moulin2015-06-112
| | | | Using multigraphs instead.
* slapd monitoring.Guilhem Moulin2015-06-101
| | | | | We don't use the provided 'slapd_' Munin plugin because it doesn't support SASL binds.
* Configure munin nodes & master.Guilhem Moulin2015-06-107
| | | | | Interhost communications are protected by stunnel4. The graphs are only visible on the master itself, and content is generated by Fast CGI.
* firewall: allow 127.0.0.1/8 on lo.Guilhem Moulin2015-06-071

* genkeypair.sh: Merge privkey and pubkey for identical filekeys.Guilhem Moulin2015-06-071
| | | | Also, set ‘subjectKeyIdentifier = hash’ in the CSR.
* logjam mitigation.Guilhem Moulin2015-06-072

* Key usage 'keyCertSign' is required for self-signed certificates.Guilhem Moulin2015-06-071
|
* 'default_days' in openssl.cnf doesn't work, use -days instead.Guilhem Moulin2015-06-071
|
* Add ability to add custom OrganizationalUnits in genkeypair.Guilhem Moulin2015-06-071
| | | | Also, it's now possible to reuse an existing private key (with -f).
* Add ability to chmod, chown and set the key usage in genkeypair.Guilhem Moulin2015-06-071
|
* Install amavisd-new on the outgoing SMTP proxy.Guilhem Moulin2015-06-071
| | | | For DKIM signing and virus checking.
* Make genkeypair.sh able to display TXT record for DKIM signatures.Guilhem Moulin2015-06-071
|
* Add support for CSR and subjectAltName in genkeypair.sh.Guilhem Moulin2015-06-071

* Don't require a PKI for IPSec.Guilhem Moulin2015-06-071
| | | | | | | | | | | Instead, generate a server certificate for each host (on the machine itself). Then fetch all these certs locally, and copy them over to each IPSec peer. That requires more certs to be stored on each machines (n vs 2), but it can be done automatically, and is easier to deploy. Note: When adding a new machine to the inventory, one needs to run the playbook on that machine (to generate the cert and fetch it locally) first, then on all other machines.
* Replace mktemp's deprecated -t option by --tmpdir.Guilhem Moulin2015-06-071
| | | | | But not in the installer, as busybox's implementation of mktemp didn't deprecate -t/-p.

* Reformulate the headers showing the license.Guilhem Moulin2015-06-071
| | | | | To be clearer, and to follow the recommendation of the FSF, we include a full header rather than a single sentence.
* wibbleGuilhem Moulin2015-06-071
| | | | | Replaced [ -n "$string" ] with [ "$string" ], and [ -z "$string" ] with [ ! "$string" ].
* Replace the 'syslog' facility (5) by 'user' (1).Guilhem Moulin2015-06-071
| | | | | 'syslog' is meant for the messages generated internally by syslogd, whereas 'user' is for user-level messages.
* wibbleGuilhem Moulin2015-06-071
|
* Be more specific regarding the protocol in use for IPSec policies.Guilhem Moulin2015-06-071
| | | | We use ESP only, so other protocols shouldn't be ACCEPTed.
* Prohibit binding against the IP reserved for IPSec.Guilhem Moulin2015-06-071
| | | | | | | | | 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 Moulin2015-06-071
| | | | 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 Moulin2015-06-071
| | | | | | | 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 Moulin2015-06-071
| | | | | | | | | | 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 Moulin2015-06-071
| | | | | These rules are automatically included by third-party servers such as strongSwan or fail2ban.
* Use a dedicated 'fail2ban' chain for fail2ban.Guilhem Moulin2015-06-071
| | | | So it doesn't mess with the high-priority rules regarding IPSec.
* Add a 'check' switch to the firewall.Guilhem Moulin2015-06-071
| | | | | 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 v4 and v6 iptable rulesets.Guilhem Moulin2015-06-071
