NethServer 7 "Bruschetta" Server-Oriented Linux OS to Support Nextcloud 10

TuxMachines - Tue, 2016-09-13 10:57

Softpedia was informed by Alessio Fattorini from the CentOS-based NethServer Linux operating system about the availability of the second Beta development milestone of the upcoming NethServer 7 release.

The first Beta of NethServer 7 "Bruschetta" was released on July 13, 2016, so it took the developers exactly two months to push a new Beta out the door for early adopters and public beta testers who either want to help them fix bugs and polish existing features, or just get an early taste of what's coming in the server-oriented distribution.

Being fully in sync with the CentOS 7 Linux repositories, NethServer 7 Beta 2 is here today, September 12, 2016, to add support for the Nextcloud 10 self-hosting cloud server platform, support for implementing advanced static routes with specific selection of metric and device, as well as to force a default gateway. It also adds a brand new bandwidth monitoring module called BandwidthD, along with a POP3 connector module.

The Best Linux Desktop for Work

TuxMachines - Tue, 2016-09-13 10:55

Wait, you doubt that there’s a best Linux desktop for work? Yes I know some users do. A lot of folks out there still believe you need a proprietary operating system to get work done.

But speaking as a user who uses various Linux distros everyday to get work done, I can tell you that for most people it's a matter of preference. Sure, there are legacy software exceptions to this rule. However between the move to the "cloud" and new Linux compatible applications popping up all the time, I've found Linux is great for getting work done.

In this article, I'll look at some of the most popular desktop Linux distros for getting work done, along with some software recommendations to make using Linux a smoother process overall.

Let's Encrypt Aiming to Encrypt the Web

Two critical bugs and more malicious apps make for a bad week for Android

LXer - Tue, 2016-09-13 09:08
The vulnerabilities, which are similar in severity to the Stagefright family of bugs disclosed last year, have been fixed in updates Google began distributing Tuesday. A large percentage of Android phones, however, aren't eligible to receive the fixes. Even those that do qualify don't receive them immediately (the September updates are currently not available as over-the-air downloads for either of the Nexus 5X devices in my household). That gives attackers crude blueprints for exploiting vulnerabilities that remain unpatched on millions of devices.

I can't be the first person to try this with LVM.

Reddit - Tue, 2016-09-13 07:08

The Logical Volume Manager can create virtual block devices that refer to specific parts of other block devices, right? I got curious what happens if you were to create a virtual block device that refers to itself. So I decided to give it a try.

First, I did ls -l /dev/dm* to find the highest-numbered LVM device; dm-2 was the last one, with major:minor 254:2. I figured that the next one would most likely be 254:3. I typed dmsetup create circular, meaning to create a virtual block device with the identifier circular. I entered 0 1 linear 254:3 0 for the table.

What happened was kind of interesting. I hit Ctrl+D to tell it I was done inputting, but nothing happened. I tried pressing it a few more times, still nothing. So I hit Ctrl+C to exit and did it again. This time Ctrl+D worked, but it gave me a "device or resource busy" error.

Apparently one of those times the command actually did complete successfully, however. Because I soon noticed my system freeze completely, with the mouse cursor not working. A while later I noticed the cursor moved a little bit, so I knew the system wasn't completely frozen. I hit Ctrl+Alt+F1 to switch to a TTY so I could figure out what was going on. The screen turned black, but the login prompt didn't appear. Shortly after, I noticed a blinking light on my laptop. It was the caps lock light. Kernel panic, I'm guessing a stack overflow.

I rebooted and looked at /var/log/syslog. There was no mention of a kernel panic (I looked it up and apparently these aren't logged because writing to the file system in that situation would be risky) but I did see a line saying that "'devices/virtual/block/dm-3' is taking a long time", and a few lines higher I saw the unnecessarily-evil-sounding "Out of memory: kill process 12164 (firefox) score 10 or sacrifice child". (The message was from a daemon, so I can't say I'm surprised.)

Has anyone else ever tried this, or am I the first?

EDIT: Just came across this message. Looks like someone else had tried the same thing via a similar method.

Is indirect SSH possible?

Reddit - Tue, 2016-09-13 04:46

Here's my situation: I'm living in student housing, and the network isolates all my devices - they can't communicate with one another at all. The ISP charges £50 for the privilege of being able to connect your devices together, which is more than I'm willing to pay. Use of a NAT is forbidden under their terms of service, the greedy swines.

I have a (Debian) Raspberry Pi which doesn't need to be directly connected to my (Arch) PC, but it definitely DOES need to be SSH-able. Clearly I can't directly access it - even ping requests are filtered. So what I've imagined is a system in which my commands go to a remote server which I CAN access, the RasPi polls this server and executes what I typed, then it sends back its response and that is polled and displayed by my PC. Convoluted, but it gets around the problem.

Now I could easily make something like this if I just want to execute commands, but I want the full console interface, with the ability to run interactive programs like vim. Is this at all possible, or am I completely mad?
