Zentyal 5.0

Building servers is Linux’s forte but deploying and configuring a server is an involved process. This is where distributions (distros) like Zentyal help save time and simplify the process with its point-and-click interface for rolling out network services.

With an intuitive graphical interface to aid the setup, you can have a working server in a fraction of the time it would take to set one up manually. The distro has a low barrier to entry and an impressive list of supported servers.

Zentyal 5.0 is based on the latest Ubuntu LTS 16.04 server release. Just like a regular incremental release, besides a newer base, it also features the latest versions of several essential components, such as the Samba server and the SOGo groupware server.

In addition to the core components and repositories (repos), Zentyal also borrows Ubuntu’s installer. After installation, Zentyal boots to a minimal graphical desktop. However, you can install it on a headless server and configure it from a browser-based interface which you can access from any computer on the same network as the Zentyal server.

When you access the browser-based administration interface for the first time, you’ll be taken through a brief installation process to help install and set up the various components of the server as per your requirements. You can safely skip this installation at this point and configure the components at a later stage.

Zentyal isn’t an all-purpose server and bills itself as a server for small businesses. This means that you can use a Zentyal installation as a domain and directory server for filtering email, scanning for viruses, managing printers, deploying webmail, VPNs and other core infrastructure services – such as DNS and DHCP – and for issuing and managing secure certificates.

Limited scope

Once installed, you can configure these services from the comfort of the web interface. Zentyal has a polished user interface and its components are nicely integrated, so you can configure the available components either individually or as a collective using the Server roles option. Surprisingly, the distro doesn’t offer an option to install and configure a web server, but you can set up Apache from its Ubuntu repos, although you’ll have to configure it the old-fashioned way, using the command-line.

While it isn’t too complex to set up, Zentyal offers plenty of options if you need some hand-holding. The project has a detailed wiki that’s got all the information you need to use and set up the distro. There are also active forum boards which are rife with tips and tricks from other users. Besides the freely available Development edition, Zentyal also offers a commercial edition for larger setups which you can test drive for 30 days.

Final verdict

If you are looking for a point and click server deployment, Zentyal isn’t the only game in town. Moreover, compared to some of its peers Zentyal offers the least number of server options. Its contemporaries, namely ClearOS and NethServer, provide just about all types of server and network services.

Apart from everything you get with Zentyal, these alternative distros let you deploy the usual LAMP, mail, FTP, file and print services. They also have additional provision to roll out web and mail proxies, chat servers, time servers and even a fax server.

We’d advise you to compare all three options before choosing one. That said, if Zentyal’s comparatively limited options are enough to serve your needs, then there’s no reason to look elsewhere.

The Legend of Zelda Breath of the Wild review

It’s been six years and two consoles since the last major home console Zelda game, Skyward Sword, and fans have understandably been getting a little antsy about getting their hands on Breath of the Wild. Originally slated as a Wii U exclusive, it’s been delayed enough to become a launch title for the Nintendo Switch (though there’s still a Wii U version too, for non-early adopters). With the rest of the launch lineup looking a bit sparse, it’s probably fair to say that most of Nintendo’s early Switch hopes are hanging on Zelda: so can it bear the weight?

Read next: Our Nintendo Switch hands-on

We’ve thrown ourselves headlong into the Switch version of the game to put it through its paces, and are happy to report that based on the first five hours or so of gameplay, we think there’s a lot to be happy about – and we’ve barely scratched the surface.

The Legend of Zelda: Breath of the Wild price & pre-orders

There are several pre-order options already available for The Legend of Zelda: Breath of the Wild in the UK.

Breath of the Wild will be a Switch launch title, and that will be the preferred platform for a lot of fans. You can pre-order it from Amazon for £48/$60, which is the best price we can find. Argos is offering it for £49.99, while Zavvi and Game are charging much more – £57.99 and £59.99 respectively.

There’s also a Special Edition version of the game for European players. This includes the game, a soundtrack CD, and a Master Sword figurine, but sadly it’s currently sold out everywhere, so you’ll want to try the second-hand market after launch for that – eBay will almost certainly have a few!

While you might expect the Wii U version to sell for slightly cheaper, right now it’s almost exactly the same – £48/$60 at Amazon, £49.85 at ShopTo, and £49.99 at Zavvi. Wii U owners won’t have access to any special edition versions of the game though.

The Legend of Zelda: Breath of the Wild hands-on review

While Skyward Sword was mostly well received, it also felt a bit tired. It was the latest in a long line of games closely aping the successful format of the N64’s Ocarina of Time, and things were beginning to feel a bit stale. Nintendo was clearly listening, and Breath of the Wild feels like nothing more than a response to that criticism. Instead of a slow tutorial, you’re thrown straight into the world and told to fend for yourself. Instead of picking up a specific item that you use to solve puzzles in each dungeon, you get a range of powers right at the beginning of the game and have to figure out which to use when. And, perhaps most importantly, instead of a rigidly structured set of environments, you’re thrown into a massive open world that you can explore with almost total freedom.

To anyone who played A Link Between Worlds on the 3DS, some of these changes will feel familiar. That game also allowed you to tackle dungeons in any order, and gave you access to almost every item early on, but Breath of the Wild pushes things even further. For one thing, your puzzle-solving tools are no longer tied to specific items like the Hookshot or Bombs. Instead , they’re split between your normal weapons and the Runes – a selection of abilities on the Sheikah Slate, a small tablet-esque device that Link discovers at the beginning of the game.

Some of the Runes will be familiar, such as bombs, which now come in both sphere and cube variants and are detonated remotely, rather than on a timer. Others are more novel. Magnesis lets you pick up and move metal objects from a distance, Cryonis lets you create pillars of ice on top of water, and Stasis lets you freeze specific objects in time and imbue them with kinetic energy while they’re frozen – whack a boulder a couple of times while it’s frozen, and after Stasis wears off it’ll go flying away.

Other Zelda staples have now been folded into the main weapon system. You can equip a variety of melee weapons, shields, bows, and arrows, and as you play you’ll regularly switch up your gear. Instead of being limited to simple swords, you can equip sledgehammers, spears, boomerangs, and even a mop as your melee weapon – and can swap between them on the fly. They can also all be thrown at enemies, though obviously only a boomerang is likely to come back afterwards. Each weapon, shield, and bow has both a strength rating and a durability, so there’s a constant push-pull between wanting to equip your best (and coolest looking) gear and wanting to save it from eventually breaking. You can also equip, upgrade, and dye various bits of clothing, which also come with their own stats and special effects.

Still, as much as all the game’s systems have changed, most of the basic mechanics have stayed the same. Combat feels instantly familiar, encouraging you to lock onto enemies, guard with your shield, and strike when they’re vulnerable. There are a few alterations even here though. For one, a successful dodge or backflip now lets you perform a slo-mo flurry of attacks for maximum damage, which is a welcome flourish. The introduction of different melee weapon types, including two-handed ones, also shifts the dynamic – Zelda has had varied melee weapons before, but has never encouraged you to use them so often, and players will want to experiment to find their preferred fighting styles and weapons. Oh, and you can no longer lock on with the bow, so you’d better start practicing your aim.

It’s a welcome point of familiarity as you go about exploring this brave new (open) world of Zelda. Thankfully, the game gives you a gentle introduction through the opening Plateau area, which will take most players two or three hours to complete. This is where you’ll learn the main mechanics and systems, collect the Runes across four mini-dungeons called Shrines (more on those later), and eventually earn the Paraglider, which you’ll need to survive the drop from the edge and make it out into the wider world.

From there, it’s up to you. The game will point you in a specific direction to follow the main questline, but you can completely ignore that and strike off wherever you like. The map is broken into 15 main areas (counting the initial Plateau), each of which is uncharted until you scale the tower at its centre – someone at Nintendo has clearly been paying attention to Ubisoft’s open world titles. Over the course of the first five hours or so we managed to visit an additional two areas beyond the initial Plateau – though they are far from completed, and we’ve barely dented the main story. Simply put, the game and world both feel absolutely massive, and we can easily believe that Breath of the Wild is up there with Final Fantasy XV and The Witcher 3 when it comes to mammoth runtimes.

There’s plenty of stuff to do along the way too. The world is littered with side quests that you can pick up from any of the NPCs dotted around the world. Then there are the Shrines, small dungeons that contain either puzzles, platforming challenges, or combat trials, and reward you with Spirit Orbs – they’re essentially Pieces of Heart, except that once you collect four you can trade them in for a boost to either your health or your stamina, which you use for climbing, sprinting, and swimming. You can also try and track down hidden Koroks littered around the world, search for hidden chests and items, and compete in a variety of mini-games and challenges. That’s not even mentioning the expansive cooking system, which sees you hunting and foraging for ingredients, which can be combined to make meals and elixirs to restore health and provide a few other buffs and status effects.

The game is beautiful, and it’s a real treat to see Hyrule brought into the world of HD. The landscape is awash with colour during the day, and foreboding and ominous by night. In our playtime we’ve seen lush forests, sparse fields, and frozen mountaintops, and we’re sure there’s more over the horizon left to find. Hyrule is packed with animals and enemies brought to life with fluid, vivid animations – if you can tear your eyes away from the landscape. We have had some very occasional framerate stutters when using some of the visually complex Runes like Magnesis, but otherwise performance is smooth, either docked or in handheld mode. As for controls, we’ve tried it with both the Joy-Con and the Pro Controller (sold separately), and much prefer the latter – it’s a more comfortable size, while the Joy-Con button configuration feels slightly squished in a game like this.

There’s a comprehensive map to go along with the huge world, which allows you to set a load of different stamps and markers to help you remember enemies, chests, shrines, and secrets that you want to go back for later on. Trying to walk across the map would take… well, bloody ages, but in fine old Zelda tradition you can get yourself a horse to speed things up. You won’t be given one though – instead you’ll have to catch a wild horse, break it in, and register it at a stable. You can name horses, and keep up to five at a time, each with their own stats, from speed to temperament – we have no doubt there’ll be some players devoting hours to finding the perfect steed.

Read next: Switch vs PS4

If there’s any criticism we can level at Breath of the Wild, it’s that occasionally it almost feels too expansive. There’s so much to do, and so many options at any given time, that the game feels overwhelming, and you can be a bit paralysed by choice at times, or spend hours wandering around before realising that you haven’t really achieved anything at all. Still, most of the side quests feel purposeful and engaging, and you never feel like you’re just being stuck spending time on filler. The less completionist among us can ignore most the side stuff and dive straight into the main story – it’s even theoretically possible to go straight to kill Ganon after you exit the starting area, but we’d guess that it wouldn’t end very well for you. Still, the Zelda speedrunning community is going to love it.

Zenimax Seeks To Block Sales Of Oculus Rift, Gear VR

Most anyone would be ecstatic if they were on the receiving end of a $500 million judgment, but evidently, cash isn’t enough for Zenimax. Reuters reported that ZeniMax is seeking to block sales of all products that rely on ZeniMax’s code. The company filed for a permanent injunction against Oculus in the same court that presided over the lawsuit.

If granted, the injunction against Oculus would put a stop to sales of the Oculus Rift VR HMD and Samsung’s Gear VR. ZeniMax purports that Oculus distributed the code in question to developers, too, which could put some VR games at risk.

At the beginning of February, the first major battle between ZeniMax and Oculus came to a bitter end. In 2014, shortly after Facebook acquired Oculus, ZeniMax famously filed a lawsuit against Oculus and its parent company. ZeniMax argued that Oculus had misappropriated trade secrets regarding VR technology and breached a non-disclosure agreement.

After three years of waiting, the trial between the two companies began in January, and it didn’t go well for Oculus. After three weeks of arguments, the jury deliberated throughout the final weekend of January and delivered a severe blow to Oculus on February 1.

The Jury cleared Oculus of the misappropriation charges but sided with ZeniMax over the non-disclosure agreement. The courts awarded ZeniMax $500 million and ordered Oculus to pay $300 million of that. The rest of the funds will come from the pockets of Palmer Luckey and Brendan Iribe.

Days after the judgment, John Carmack responded to the situation with a post on his Facebook page in which he expressed his displeasure with the outcome. He argued that the methods used by ZeniMax’s expert were questionable, and he insinuated that the prosecution used vague terms to help sway the narrative.

Oculus, of course, isn’t satisfied with the outcome and intends to continue fighting the judgment. Following the court’s ruling, Oculus said it would file an appeal.

We reached out to ZeniMax for a comment but have yet to receive a response. We also spoke with Oculus, which had this to say about the situation:

ZeniMax’s motion does not change the fact that the verdict was legally flawed and factually unwarranted.  We look forward to filing our own motion to set aside the jury’s verdict and, if necessary, filing an appeal that will allow us to put this litigation behind us.

Evidently, Oculus isn’t ready to go down without a fight, but there’s more at stake here for the VR industry in general; the loss of a major player this early could be a major setback for the entire market.

Intel Pentium G4620 And G4560 Review: Now With Hyper-Threading

Enthusiasts and casual users alike have suffered from the slow trickle of CPU innovation over the last several years. Each new generation brings smaller improvements, and lately, stagnant pricing. Intel’s 14nm Kaby Lake architecture, which marks the company’s transition to an extended tick-tock-tock cadence, sets the stage for even less excitement from each generation. We appreciate faster transistors that provide higher clock rates, along with Intel’s improved media capabilities, but the rewarmed Skylake design won’t inspire anyone with a fairly modern PC to upgrade.

Although the high-end processors give us little to talk about, Intel’s recent realignment of the Core i3 and Pentium families are a bit more newsworthy. First, the company launched an unlocked Core i3-7350K, and though it doesn’t offer the value we expect from an i3, it is a fun chip for tuners.

Intel also infused the Kaby Lake-based Pentiums with 100-200 MHz of extra frequency. More important, they now enjoy the benefit of Hyper-Threading technology. In the past, Hyper-Threading was a key differentiator between the Core i3 and Pentium CPUs, but the dual-core chip’s ability to operate on four threads simultaneously could put today’s Pentiums on-par with some of yesterday’s low-end Core i3s. Hyper-Threading can boost performance up to 30%, and though we usually see ~20% gains in applications optimized for parallelization (mileage varies, of course), this move also opens the door to games that require four threads.  

Kaby Lake Pentiums still include 3MB of last-level cache shared across the die, which is another differentiating feature compared to the 4MB-equipped Core i3s. Thankfully, the Pentiums do include a heat sink, which will help value-seekers keep costs down.

The 51W Pentium G4620 is the family’s highest-end model. Its 3.7 GHz base frequency is only 100 MHz higher than the previous-gen G4520. As with all Pentiums, Turbo Boost is not supported. The chip does feature HD Graphics 630, though, and the Gen 9.5 graphics architecture provides fixed-function hardware for HEVC 10-bit decode/encode, VP9 8/10-bit decode, and VP9 8-bit encode. The G4620 offers promising performance, but its $93 price tag comes uncomfortably close to the Core i3 series. 

The 54W Pentium G4650 appears to offer better value with its 3.5 GHz base clock rate and $64 price tag. That’s 31% less money for a 200 MHz sacrifice. The G4560 even challenges low-end Core i3 CPUs. Although it operates at a lower frequency than the 3.9 GHz Kaby Lake i3-7100 and 3.7 GHz Skylake i3-6100, it retails for $53 less. The Pentium G4560 drops you back to HD Graphics 610 with a lower 1050 GHz turbo clock rate, but most Tom’s Hardware readers will probably pair the Pentium with a mainstream add-in graphics card. 

Intel did make a few adjustments to prevent the Pentiums from plundering sales of its own more expensive models. The company nixed support for AVX/AVX2 instructions and TSX-NI, though we don’t expect those omissions to hurt low-cost gaming machines much. It also trimmed Optane support, which is one of the few reasons to upgrade to a 200-series motherboard. We don’t know what price Intel’s Optane caching will command when it comes to market later this year, but we’re fairly confident that the technology won’t be aimed at entry-level machines. Although the H270 and B250 platform controller hubs offer more connectivity than their predecessors due to increased HSIO lane allocations, if you don’t need those features, low-cost 100-series motherboards are plenty attractive (and less expensive).

Some games benefit more from high clock rates more than any other specification, and most titles played on a mainstream gaming system will be graphics-bound before a CPU bottleneck rears its ugly head. Either one of the Pentiums we’re reviewing complement low-cost motherboards and sub-$200 graphics cards for reasonable 1080p performance. But at the price points we’re talking about, we want to really optimize for value. Let’s see if the G4620’s slightly higher clock rate is worth the big premium.

Cloudflare bug data leak exposed

Private messages exchanged on dating sites, hotel bookings and frames from adult videos were among the data inadvertently exposed by a bug discovered in the Cloudflare network.

The firm protects websites by routing their traffic through its own network, filtering out hack attacks.

It has 4 million clients, including banks, governments and shopping sites.

Customers wouldn’t necessarily know which of the online services they use run on Cloudflare as it is not visible.

The bug came to light while Cloudflare was migrating from older to newer software between 13 – 18 February.

Chief operating officer John Graham-Cumming said it was likely that in the last week, around 120,000 web pages per day may have contained some unencrypted private data, along with other junk text, along the bottom.

He told the BBC there was no evidence yet that the data had been used maliciously.

“I can’t tell you it’s zero probability that nobody saw something and did something mischievous,” he said.

“I am not changing any of my passwords. I think the probability that somebody saw something is so low it’s not something I am concerned about.”

‘Ancient software’

Mr Graham-Cumming has written a blog about what went wrong and how Cloudflare fixed it.

“Unfortunately, it was the ancient piece of software that contained a latent security problem and that problem only showed up as we were in the process of migrating away from it,” he wrote.

The firm, whose strapline is “make the internet work the way it should”, has also been working with the major search engines to get the data scrubbed from their caches – snapshots taken of pages at various times.

It was discovered by Google engineer Tavis Ormandy, who compared it to the 2014 Heartbleed bug.

“We keep finding more sensitive data that we need to clean up,” he wrote in a log of the discovery.

“The examples we’re finding are so bad, I cancelled some weekend plans to go into the office on Sunday to help build some tools to clean up.”

Dodged bullet

Cybersecurity expert Prof Alan Woodward said the bug had been caused by “a few lines of errant code”.

“When you consider the millions of lines of code that are protecting us out there on the web, it makes you realise that there are bound to be other problems likely to be waiting to be found,” he said.

“It’s too soon to tell exactly what damage may have been done, but because of the way in which this was found the chances of individuals being compromised is relatively small.

“What it shows, bigly, is that we may have just dodged a bullet.”

How to easily keep your cloud files private with Rclone

When cloud storage services first came on the scene, personal data security wasn’t a common feature. Even now, as concern over data privacy has grown, many cloud storage services don’t encrypt the user’s data by default. It’s largely up to the user to take the initiative and enable settings that ensure files are encrypted and private, which can be tedious. Believe it or not, a little command-line program called Rclone simplifies things. It’s available for Linux and other open-source OSes, as well as Windows and OS X.

There are several ways to encrypt your data before you send it to the cloud, but if you simply want to back up or sync your data while keeping it private, Rclone has you covered. Rclone is a bit like the command-line tool rsync, a staple for developers and other advanced users. However, Rclone is designed to work with established cloud services, no need to set up rsync services on remote machines. Rclone can work with Google Drive, Amazon S3, Dropbox, Google Cloud Storage, Amazon Drive, Microsoft One Drive, Hubic, and Backblaze B2, just to name a few.

Setting up RcloneAlex Campbell

Even though Rclone is a command-line tool, setup is easy with the guided menus.


To start using Rclone, you have to set up remotes, meaning profiles for cloud destinations. Once you have Rclone installed using your Linux distribution’s package manager, you can start setting up Rclone. Type the command rclone config to access a simple guided setup process that’s quite easy to follow.

Rclone requests access to Google DriveAlex Campbell

Upon setting up my Google Drive account, Rclone popped open a browser window to ask for access. No need to copy and paste API keys.

The first step is setting up an unencrypted remote. As you can see in my example above, I connected Rclone to my Google Drive account, then named the remote “gdrive.” The configuration automatically opened a browser window in order for me to grant access to my Google account. From there, the configuration application will prompt the user for the path that the user wants to sync. If you’re using a bucket service (like Amazon S3 or Backblaze B2), be sure to enter the name of the bucket you want to use.

Once the initial setup is done, it’s time to set up the encrypted remote, again with rclone config. Encrypted remotes piggyback on remotes that have already been set up. When choosing the type of remote to set up in the configuration program, choose the encrypted remote option (5) Encrypt/Decrypt a remote “crypt.” You’ll be prompted for the name of the remote to piggyback on (in my case gdrive), as well as a name you want to give the encrypted remote.

Setting up an encrypted remote with RcloneAlex Campbell

Setting up an encrypted remote with Rclone.

You’ll also be prompted for passwords and a salt to use to encrypt your files. If you don’t want to bother with creating a super-secret-secure passphrase, you can allow the program to generate a random passphrase and salt for you. You an even ask Rclone to encrypt the names of files and folders so you don’t leak metadata from you filenames.

Once you have the two remotes set up, you’re off to the races.

Sync those files

There are a few ways you can use Rclone to push and pull data to and from the cloud. Unlike its cousin rsync, Rclone won’t do a bidirectional sync (yet). That means choosing a sync method that works best for you.
