twitter bootstrap – 4 bucket elements do not respond

enter the description of the image hereI have 4 bucket elements coded with bootstrap and a php loop in wordpress. I want the 4 bucket elements to appear in a row for the desktop and be reduced to columns on mobile. This is the only way for me to make them appear in a row on the desk. However, I can not reduce them using multimedia queries, such as flex-direction: column.


'posts_per_page' => '4',


$blogposts = new WP_Query($args);





centos – NGINX does not respond to queries behind NAT

Warning: I am a beginner to NGINX. I used apache2 but under CentOS, I am not used to how it is configured and I also want to try NGINX since its most recent and most modern version.

I have a simple VM solution running on VMWare. All virtual machines run CentOS 7 with selinux disabled.

Virtual Machine # 1 is the gateway. It has two network cards, eth0 – internal network, eth1 – wan.
This virtual machine has also configured iptables. I have basic rules that basically allow all the traffic, but block some unwanted ones. There are also NAT rules for forwarding these desired requests for the HTTP port and the HTTP port to the internal virtual machine as follows:

-A PREROUTING -p tcp -m tcp -i eth1 --dport 80 -j DNAT --to-destination
-A PREROUTING -p tcp -m tcp -i eth1 --dport 443 -j DNAT --to-destination
-A PREROUTING -p tcp -m tcp -i eth1 --dport 3306 -j DNAT --to-destination
-A PREROUTING -p tcp -m tcp -i eth1 --dport 993 -j DNAT --to-destination
-A PREROUTING -p tcp -m tcp -i eth1 --dport 25 -j DNAT --to-destination
-A PREROUTING -p tcp -m tcp -i eth1 --dport 465 -j DNAT --to-destination
-A PREROUTING -p tcp -m tcp -i eth1 --dport 587 -j DNAT --to-destination

VM # 2 is the web server. It runs NGINX. It has the default configuration:

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/;

include /usr/share/nginx/modules/*.conf;

events {
    worker_connections 1024;

http {
    log_format  main  '$remote_addr - $remote_user ($time_local) "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 2048;

    include             /etc/nginx/mime.types;
    default_type        application/octet-stream;

    include /etc/nginx/conf.d/*.conf;

    include /etc/nginx/sites-enabled/*.conf;
    server_names_hash_bucket_size 64;

    server {
        listen       80 default_server;
        listen       (::):80 default_server;
        server_name  _;
        root         /usr/share/nginx/html;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;

        location / {

        error_page 404 /404.html;
            location = /40x.html {

        error_page 500 502 503 504 /50x.html;
            location = /50x.html {


Now, when I loop from the gateway, I get:

curl: (7) Failed connect to; No route to host

but ping works like a charm.

Likewise, when you try the external IP WAN, the connection is refused.

I am very confused at this point and I do not know what I should try and test next. When I add NAT for ssh, I can access it without problem. But these HTTP / s requests do not work. Is this a problem with NGINX? Do I have to do something else with the firewall so that the NGINX server can answer queries outside of the virtual machine?

Thank you!

The TCP server does not respond to the directly connected Ethernet client

I have a TCP server in NODE RED that listens to port 12020 (PC1). I have a computer connected directly via the interface (PC2).

PC1 has an IP mask
PC2 has an IP mask

PC1 receives a TCP SYNC packet from PC2 but never responds.
However, if I have a WiFi PC3 and a WiFi PC1 via the router, the PC3 client is properly connected to the PC1 server on port 12020.

(Note not even ping one to the other)

Would it be a firewall problem?
Could it be that the server listens only to port 12020 and the IP address of the WiFi interface?

Reset the board? Process System does not respond AND no keyboard

I have a Samsung Note 4 under Android 6.0.1. After installing the "Guidebook" application, I started to frequently receive the message "The system is not responding". If I restart, I get it immediately at startup. If I say "ok" to end it, the phone is a little usable, but not very. In particular, I can not bring up a keyboard when I try to enter something in a text field, regardless of the context.

My default keyboard is Swype which I would like not to lose because it is no longer available, but if I have to go to GBoard or something, I will survive.

As my internal storage space was already insufficient, I removed several applications and files, including Guidebook. I am now at just under 30GB used on 32.

I have tried to install GBoard in the hope of running a keyboard. I did this by logging into Google Play on my laptop and requesting installation, but my phone has not yet downloaded / installed it (several hours later). It's hard to use Google Play on my phone without a keyboard. It hangs in all the tabs under "My apps and my games".

So … I'm almost sure I need to reset the phone at the factory and I wonder how to lose as little as possible. I have an external SD card installed and a lot of photos and application data stored on it. The photos are saved on Google Images, but I do not know if they are in full resolution. I copy them to USB on my laptop. I do not know what else I might want / need to back up manually. Can I save the application data? The phone is still semi-usable, but I do not seem to be able to use Google Play to install apps. Maybe I could put something next. The phone is not rooted and I do not really want to do it because it really goes beyond my area of ​​expertise.

2 major question:

1) Is there anything I should try before doing a factory reset?

2) If / when I reset the factory settings, do I have to remove the SD card first? If I do, will it be readable by the phone once it has been reset? What will happen if I leave it in?

Please let me know if there is any additional information you need and I will try to provide you with it. Thank you!

domain name system – the BIND 9 master does not respond with an extra section

We are running BIND ISDN BIND 9.14.3 64-bit on a Windows Server 2008 R2 behind NAT. This is the master server. There are three externalized slave servers (I do not know which DNS software is running). Slave servers return an extra section, even for out-of-box records, but not the BIND master.

The options in named.conf are:

options {

directory "c:  named";
listening port 5353 {; };
listen-on-v6 {none; };
allow-query {any; };
pid file "etc";
recursion no;
text in masterfile format;
rrset-order {class IN type ANY name "*" cyclic order; };
minimal answers no;
supplement-from-auth yes;
supplement-from-cache yes;


Using dig to query the master server does not return an additional section:

I do not know what other configuration needs to be done in the BIND named.conf file to get answers with an extra section.

Thank you for your help.

Cordially. does not respond to Copyright DMCA.

I am an AWS client and run a content website.

Someone else started copying my website and as soon as I publish a content, it basically tears up the content, images and everything else.

At this point, they have the exact replica of my content on their website.

Their website is hosted on OVH and DNS is managed via CloudFlare.

I've bypassed the CloudFlare team and they've told me that the server is run by OVH and that they can not do anything for my problem.

Since 3 or 4 days, I contact the team of, but it does not answer any complaint for abuse. OVH is becoming a haven for all the abusers in the world.

The website in question that copies the content is Prohint (dot) com. The original website in question is Reapon (dot) com.

I do not think about contacting the upstream supplier. Can someone tell me what to do next and who should I contact?

Since DNS is managed through CloudFlare, I can not find the primary IP address or contact anyone else in this regard.

Why does haproxy respond with a 403 using path_beg?

backend letsencrypt-backend

The above generates a 403 if I loop curl -vk

What is strange, there is no Deny rules as far as I can see? Other pages work well (without the well known / acme-challenge / prefix).
