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.
|
|
|
|
| |
Other abreviations are upper case.

(For now, only LMTP and IMAP processes, without replication.)

(Hence the SyncProv overlay.)
|
|
|
|
|
|
|
|
|
|
|

A 'suffix=' parameter has been added to choose the database to configure
the overlay for.
The ability to delete overlays would be desirable, but sadly there is no
cleane way to remove/replace overlays, short of stopping slapd and
digging into the slapd.d directory:

As of 2.9.6 (2.10), at least. See bug #730848.

This is because the UNIX domain socket to connect to when performing
LDAP lookups needs to be in the chroot.
Also, don't open a INET socket unless we're a Sync Provider.

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.)

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.

"username=postfix,cn=peercred,cn=external,cn=auth" is replaced by
"gidNumber=106+uidNumber=102,cn=peercred,cn=external,cn=auth" where 102
is postfix's UID and 106 its primary GID (looked up from /etc/passwd).

I.e., put 'sudo=True' in ansible.cfg.

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.

Since indices are specified in the database LDIF.

It's not happy with non-ASCII characters in comments, unless the
encoding is made explicit…

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

A.k.a "IDENTIFIED WITH ...". The plugin is automatically loaded on first
use.

Sadly as of MySQL 5.5, the "ALTER USER" command does not allow changing
the Authentication Plugin, so we have to manually manipulate
`mysql.user` (and FLUSH PRIVILEGES) instead. See also

From ref origin/release1.4.0, commit
2a58c2bbe33236ccfdde9fe7466d8a65956f21a5
|
|

|
| |
We use a dedicated instance for each role: MDA, MTA out, MX, etc.
|
|
|
|
|
| |
${distro_codename} doesn't work properly there, so we put stable and/or
oldstable instead.
|
|
|
|
|
| |
Replaced [ -n "$string" ] with [ "$string" ], and [ -z "$string" ] with
[ ! "$string" ].

'syslog' is meant for the messages generated internally by syslogd,
whereas 'user' is for user-level messages.

We use ESP only, so other protocols shouldn't be ACCEPTed.
|
|

This is pointless since the service will be restarted anyway.
|
|
|
|
|
|
|
|
|
| |
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.)

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
|
|
|
|
| |
Also, use ESP tunnel mode instead of transport mode.
|
|
|
|
| |
I.e., as packets are treated along the way: mangle -> nat -> filter.
|
| |
|
|
|
|
|
|
|
| |
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.

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
|
|
|
|
|
| |
These rules are automatically included by third-party servers such as
strongSwan or fail2ban.
|
|
|
|
| |
So it doesn't mess with the high-priority rules regarding IPSec.

update-firewall.sh -c does not update the firewall, but returns a
non-zero value iff. running it without the switch would modify it.
