Como actualizar Appliance

If you are running our Debian-based appliances and have enabled automatic updates, the appliance will update to 3.4.0 overnight.

If you wish to upgrade your Debian-based appliance manually, log in as root and type the following command:

upgrade-canit-appliance

If that command is not found, then your existing appliance version is too old. In that case, type the following commands:

apt-get update
export UCF_FORCE_CONFFOLD=1
apt-get dist-upgrade -y -o DPkg::Options::=--force-confold

Novedades 3.4.0

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hello,

I'm pleased to announce the immediate availability of CanIt, CanIt-PRO and CanIt-Domain-PRO version 3.4.0. The software may be downloaded from

Here's a summary of the major changes:

o MAJOR NEW FEATURE: The old "Access Rights" page is gone. In its place
are far more flexible "Permissions" pages. These allow fine-grained control
over permissions on a per-user and per-group basis. The database upgrade
code should migrate the old Access Rights to the new Permissions accurately.

o MAJOR IMPROVEMENT (CanIt-PRO and Domain-PRO only): Hit-and-Run (also
known as "Greylisting") can be enabled on a per-stream basis. However,
greylisting is now always done after the DATA phase of SMTP.

o MAJOR CHANGE (CanIt-PRO and Domain-PRO only): The old "Stream Redirection"
concept is gone. In its place we have "Stream Inheritance". This is
more flexible and simplifies the code a lot. The database upgrade code
will migrate Redirection to Inheritance.

o PERFORMANCE IMPROVEMENT: A new caching scheme has reduced the number
of database queries per e-mail substantially, sometimes by more than
50%.

o POLICY CHANGE: We have removed support for a shared Bayes database in
CanIt-PRO. It complicated the code very much and never really worked
well.

o INCOMPATIBILITY: CanIt now requires PostgreSQL 7.3 or newer. It will
NO LONGER WORK with PostgreSQL 7.2.x or older!

In addition, there are many other bug fixes, performance improvements and new features -- see the full release notes for details. Because this release includes major changes to permissions and redirection/inheritance, we encourage you to do a test upgrade on a non-production server first, just to ensure that permissions and inheritance behave the way you expect.
Although the upgrade process tries its best to keep the same semantics as before, it might not be possible in all cases.

Novedades 3.4.3

Release Notes for CanIt-3.4.3: 2007-03-26

o NEW ARCHITECTURE: We now have RPM packages for Red Hat Enterprise Linux 5

o BUG FIX: The VACUUM and database backup cron jobs would fail on password-
protected databases. They now work correctly.

o BUG FIX: When Bayes votes were acted upon, CanIt forgot to record the
vote in the Bayes signature table (although it did correctly update the
Bayes statistics.) The vote is now properly recorded.

o BUG FIX (CanIt-PRO and higher only): The Web interface and Perl code
disagreed about the default value for "Permit use of auto-whitelisting".
They are now in agreement.

o BUG FIX: The cron script would sometimes fail to find required Perl modules
on Solaris, and the locking mechanism would fail on Solaris, Both of
these problems have been fixed.

o BUG FIX: When switching streams after doing an Advanced Query, the
query would be forgotten. It is now correctly remembered.

o BUG FIX (CanIt only): Some PHP pages such as Bayes Settings would fail
to render on Standard CanIt. This has been fixed.

o BUG FIX: The host IP in the Report pages did not link to a proper WHOIS
query URL. This has been fixed.
