Maia Mailguard: GUI d’amavisd-new (PHP+perl)

A tavés d’un article de la Linux Journald he trobat una eina que em canviarà la vida a nivell del correu brossa, una passada:

The Maia Mailguard project began its life as a simple Web front end for amavisd-new, designed to let users
adjust their content filter settings and manage their quarantines from a convenient interface. The project
proved quite popular with ISPs, Web-mail providers and companies offering off-site content filtering,
however, and the needs of these larger-scale clients soon developed Maia Mailguard into something much more
sophisticated.

Maia Mailguard is a complete spam and virus management system, consisting of PHP, SQL and Perl scripts, a
MySQL or PostgreSQL database and, of course, amavisd-new, SpamAssassin and supported virus scanners. Arrays
of content filters can be managed from a single Maia interface, all sharing the same SQL database. Designed
to make content filtering, quarantine management and spam reporting easier, Maia Mailguard is in many ways a
new kind of tool for mail users.

Ja ens comencen a taladrar amb les històries de duro sobre la 3G

LUFS: ex ftpfs, sshfs, etc

LUFS
is enabling you to mount into your file hierarchy a remote computer’s file
system, which is accessible by various means (ftp, ssh, etc.). Then, the access
to the remote files will be completely network transparent. In other words,
you’ll be able to read/modify remote files as if they were local, watch
movies/listen to MP3s from FTP/SSH/Gnutella servers without copying them
locally.

The reason for the
userspace stuff: there are operations only suited for userspace
(cryptography for example) and implementing them in kernel would be
bloat.

The reason for the kernel
stuff: I think it’s important to keep the file system access point at
the lowest level in order to allow all the applications to use it.
Consider KDE: it implements its own virtual file system, a great one,
but only KDE applications can take advantage of it. So does GNOME, MC
and others. Suddenly we have lots of overlapping userspace file
system implementations, a real waste…

Communication between the
kernel module and the daemon is done through UNIX domain sockets.
This makes LUFS best suited for networked file systems, where this
indirection overhead (userspace <-> kernel <-> userspace)
is small compared to the speed penalty due to the network itself.

LUFS can be regarded as
doing the same job as the VFS (virtual file system switch) in the
kernel: it is a switch, distributing the file system calls to its
supported file systems. With a big difference: LUFS file systems are
implemented in userspace. This would be a drawback for local file
systems where the access speed is important, but proves to be a huge
advantage for networked file systems where the userland
flexibility is most important.

This flexibility allowed
for implementation of SSHFS for example, in a pretty straightforward
manner, using the already existing openssh
infrastructure. Lots of other “exotic” file systems are in the
planning phase: socketfs, httpfs, webdavfs, freenetfs, etc. Just
imagine mounting a freenet file system and accessing all the goodies
as they were local…
