This is it. After more than a decade I had to install a different E-mail/Collaboration server than Zimbra.

Carbonio from Zextras is a great tool and if it still have a loot to improve it’s ready to go in production and full fill most users needs to replace Zimbra as a popular E-mail server.

Don’t fool yourself, Carbonio is a lot different and have many extra components, but it’s core still is a Zimbra., meaning that most “zm” commands are available and also it’s 4 pillars mysql + openldap + postfix + jetty still are there. What Zextra did so far was add a new interface, libreoffice and a service networking solution called Consult to help to integrate it all. It’s a pretty damn good work.

After many test in controlled environment I finally migrated my first server to Carbonio and I took inspiration o a very handy tool done by Fábio Schidt called Z2Z to make this scripts to help migrate from Zimbra to Carbonio.

In the end I realized that processes were not so different and with just a few adjusts it could also be used to migrate from Zimbra to Carbonio and vice-versa, but also from Z2Z and Z2Z =)

You can download it here: Z2C

INSTALL

Z2C is a quite simple pair of scripts to export LDAP data from an origin Zimbra or Carbonio server and import it on a brand new Zimbra or Carbonio server. It’s goal is to migrate a

ccounts and help to dump and restore mailboxes from one server to another.

As simple as it is, there is no need for install anything. Just run the scripts:

1 – z2c.sh to export it all from the original server

2 – copy a Z2C folder to the new server

3 – fix it’s permission on the new server

4 – restore.sh to import it on the new server

Those steps will export users, aliases and lists from the one server and import it on the new one.

MAILBOXES

Once you have all domains, accounts, aliases and list imported on the new server it’s time to dump mailboxes on the original server, copy it to the new one and then retore it there

.

Z2C make it pretty easy for you, creating a full set of scripts:

script_export_FULL.sh   -> a list of zmmailbox commands to dump all mailboxes;

script_export_TRASH.sh  -> a list of zmmailbox commands to dump the Trash folder, because it’s not dumped on the regular command and some users can’t live without it’s Trash =)

script_import_FULL.sh   -> a list of zmmailbox commands to restore all mailboxes;

script_import_TRASH.sh  -> a list of zmmailbox commands to restore the Trash folder, because it’s not restored on the regular command and some users can’t live without it’s Trash =

)

script_import_quota.txt -> a list of zmprov commands to restore all accounts quotas if you need it;

users.txt               -> just a list of users to make it at hand in case you want to script anything #nerdfellings

PARALLEL

You may consider to install and run those scripts using parallel to make dumps and restores faster.

Those script are great but it may take quite a long time to run it if you have hundreds or thousands of accounts, so be able to run many at the same time in a non stop way it’s faster, by far.

Just take care to don’t do too many at the same time, your server may not be able to deal with the overload. We suggest you to use between 3 and 5 simultaneously dumps/restore, but

feel free to test it out.

This is how you use it:

Arm Holdings plc today announced that it has made a strategic investment, a minority stake in Raspberry Pi Ltd — the arm of Raspberry Pi responsible for the new Raspberry Pi 5 and past Raspberry Pi products. 

Arm's minority stake extends the long-term partnership between Arm and Raspberry Pi, which has seen Arm CPUs feature in all of the Raspberry Pi and Raspberry Pi Pico SoC. The partnership began way before the Raspberry Pi was available for sale, in 2008 — when the original board was still just a dream. Fast-forward to 2023 and we have a generation of learners who have taken their first steps with coding, science and electronics thanks to the Raspberry Pi.

“Arm and Raspberry Pi share a vision to make computing accessible for all, by lowering barriers to innovation so that anyone, anywhere can learn, experience and create new IoT solutions,” said Paul Williamson, SVP and GM, Internet of Things Line of Business, Arm. 

“With the rapid growth of edge and endpoint AI applications, platforms like those from Raspberry Pi, built on Arm, are critical to driving the adoption of high-performance IoT devices globally by enabling developers to innovate faster and more easily. This strategic investment is further proof of our continued commitment to the developer community, and to our partnership with Raspberry Pi.”

“Arm technology has always been central to the platforms we create, and this investment is an important milestone in our longstanding partnership,” said Eben Upton, CEO, Raspberry Pi. 

“Using Arm technology as the foundation of our current and future products offers us access to the compute performance, energy efficiency and extensive software ecosystem we need, as we continue to remove barriers to entry for everyone, from students and enthusiasts, to professional developers deploying commercial IoT systems at scale.”

The Raspberry Pi range of single board computers has grown in power since the initial 2012 board was released with a single-core Arm CPU running at 700 MHz. The recent Raspberry Pi 5 is based around an Arm Cortex-A76 64-bit CPU running at 2.4 GHz, performing approximately 2-3 times better than the Raspberry Pi 4. 

Arm's minority stake in Raspberry Pi Ltd also shows a firm commitment to the continuation of Arm CPUs in future Raspberry Pis. With the rise of RISC-V CPUs in devices ranging from $9 to hundreds of dollars it is clear to see that we will not be seeing a RISC-V based Raspberry Pi for the foreseeable future.

In recent years, WhatsApp has become the go-to messaging app for many people around the world. However, along with its popularity, WhatsApp has also become a hub for spam and marketing messages. This was one of the reasons why millions of people switched from traditional SMS messaging to WhatsApp. Unfortunately, the sophistication of scams on WhatsApp is evolving, and users are facing new challenges.

This is the first switch review in a new series. We found this new 4-port 2.5GbE and 2-port SFP+ 10GbE switches on Amazon for under $69 and decided to give it a try. It feels a bit like the YuanLey YS25-0402 is trying to take over the role of the cheap Netgear switch in the 2.5GbE space. While this is far from the $20 4-port 1GbE switch, it offers 7.5x the switching capacity at around 3.5x the price. Best of all, it is fanless.

In an X post on Thursday, Musk also named some of the feature’s traits. Audio and video calls will work on iOS, Android, Mac, and PC, and no phone number will be needed. Musk also called X “the effective global address book.”

In terms of AI startups, Cerebras has been our front-runner to make it to the next stage for years. Now, it seems to have exited a gaggle of startups scaling its giant wafer scale engine to AI supercomputer scale (for revenue.) At Hot Chips 2023, the company is detailing the new cluster that it plans to use to dwarf what NVIDIA is building.

Devoid of emotions, machines impartially serve humanity, don’t they? Regrettably, as products of human creation, computers reflect our ingenuity and imperfections all the same.

Envision a scenario where decision-making is entrusted to machines, and robotic entities are tasked with determining matters like granting loans and diagnosing diseases. The promise lies in the potential to eradicate biases. Yet, the reality paints a different picture, where these non-sentient machines pass judgments with a severity reminiscent of high school days.

Setting aside the ethical and environmental concerns around AI and those of autonomous drones for a minute, we can marvel at this latest feat: an AI-controlled drone system that beat three professional drone pilots in a series of head-to-head races, winning more often than not.

Swift is the name of the autonomous system, which outmaneuvered the world-champion human pilots in 15 of the 25 races, on a track full of sweeping turns and screeching pivots designed by a professional drone-racing pilot.

Proof-of-concept exploit code has been publicly released for vulnerabilities in Juniper SRX firewalls that, when chained, can allow unauthenticated attackers to gain remote code execution in Juniper's JunOS on unpatched devices.

Juniper disclosed four medium-severity bugs in its EX switches and SRX firewalls and released security patches two weeks ago.

The security flaws were found in the PHP-based J-Web interface that admins can use to manage and configure Juniper devices on their networks.

The leak of the LockBit 3.0 ransomware builder last year has led to threat actors abusing the tool to spawn new variants.

Russian cybersecurity company Kaspersky said it detected a ransomware intrusion that deployed a version of LockBit but with a markedly different ransom demand procedure.

"The attacker behind this incident decided to use a different ransom note with a headline related to a previously unknown group, called NATIONAL HAZARD AGENCY," security researchers Eduardo Ovalle and Francesco Figurelli said.
