Google Kubernetes Engine nodes do not have a package manager to install debug tools. You need to use `toolbox` for thatEasily mount a Google Cloud Storage bucket in a Linux file system using gcsfuse and use it as if a local disk attachedIf you are trying to setup your Raspberry Pi ( Running Raspbian ) without a
monitor, you might be in for a surprise.
Well, the new Raspbian versions do not have SSH enabled by default, and for good
Most people who setup a RaspberryPi do not even change the default password and
they connect it to the internet.
And these RaspberryPis become part of a botnet in no time.
Anyways, let's see how to enable SSH.
Enable SSH in Raspbian
1. Prepare the SD card with Raspbian
2. ConnectWhen it comes to Docker containers, even a simple task can be pretty confusing,
like the cron jobs.
I know it was confusing for me at least. And I had to spent a lot of time
scratching my head because my cron job just won't start.
Before we dive into how to setup the cron daemon to work with Docker containers,
let's look into a problem I ran into AFTER setting up the cron in Docker, in
Kubernetes running on Google Container Engine. This will be particulary helpful
to those who managedToday I updated the Docker daemon on my Mac ( Running macOS Sierra ) and after
that, I just could not push any images to Google Container Registry. It fails
with the following message
➜ gcloud docker -- push asia.gcr.io/my-project/my-image
ERROR: Docker CLI operation failed:
Error response from daemon: login attempt to https://appengine.gcr.io/v2/ failed with status: 404 Not Found
ERROR: (gcloud.docker) Docker login failed.
Luckily, the fix was simple enough.
Click on the Docker icon >> PrIt is evident that you don't need an introduction to Docker, WordPress or Nginx.
So there is no point whatsoever in blabbering about each of these technologies,
let's just jump right into the matter.
In this article, we will be looking into how you can setup a WordPress site in a
Docker container that will be using Nginx along with php7-fpm.
What's included in this Dockerfile?
The Docker image you create using the following Dockerfile will have the

* Nginx (latest aIf you just started out with Golang, you'd find it a bit difficult to handle
logging with the default pacakge log
Don't get me wrong, it's powerful and all, but for a beginner, you have to do a
lot of stuff manually. For example,
it doesn't have log levels like Info, Warning, Debug, Error by default. You have
to add them manually.
If you come from a language like Python (like me), you would find it a bit
different. Anyway, logrus to the rescue.
Logrus [https://github.com/sirupsen/logrus] is a I am gonna make it short and simple. This issue is something I have seen on so
many Debian 7 servers.
It goes like this. You're trying to list your iptables rules and you're seeing
[email protected]~# iptables -L
WARNING: Could not open 'kernel/net/netfilter/x_tables.ko': No such file or directory
FATAL: Could not open 'kernel/net/ipv4/netfilter/ip_tables.ko': No such file or directory

with you an easter egg hidden in the Linux reboot() system call.
From man page of reboot
int reboot(int magic, int magic2, int cmd, void *arg);
The reboot() call reboots the system, or enables/disables the reboot
keystroke (abbreviated CAD, since the default is Ctrl-Alt-Delete; it
can be changed using loadkeys(1)).
This systSetting up OpenVPN on your own server can be real pain in the a**. I know a lot
of you would agree with me there.
Today, I'll show you guys how to setup OpenVPN and manage users without any
hiccups. I don't think this can get any easier. Enter Pritunl. You install a few
packages and you're done. You have a fully functional VPN server with a web
interface where you can manage your users, servers, organizations etc.
What is Pritunl?
Pritunl is a distributed enterprise vpn server built using the OLet's keep it short and simple. You have a problem with Wpscan on your Kali
Linux machine and you need to fix this thing and get to work.
So, yeah. This is how the problem looks like.
When you try to run wpscan, it says "cannot load such file --
nokogiri/nokogiri". It basically means that a ruby gem that is required by
wpscan is not installed. This probably happened after an update.
[email protected]:~# wpscan --help
[ERROR] cannot load such file -- nokogiri/nokogiri
Anyway, the fix is quite simple.Why SSH Tunnel?
Consider the situation you are in a network you don't trust, like a coffee
house. You never know who is snooping around the network for any kind of
information they can collect. Or you are in a corporate network where the
service you need is disabled in the network level, like spotify, or even steam.
To make it worse, you do not have access to a VPN either. What do you do? Well,
if you have an SSH account in a remote server, that could serve you well in this
