vpn – Does the Load Balancing of Multiple WAN Connections Improve Anonymity?

I would like to understand the pros and cons of balancing outgoing connections for anonymity.

Scenario 1: My Router (ip A)> VPN Router (ip B)> VPN Router (ip C)> Web Host

Scenario 2: My Router (ip A)> 3 Load Balanced VPN Client Connections (ips B C D)> 3 Separate Connections Leaving VPN Routers (ips E F G)> Web Host

Continuing my sorry curiosity,
What happens if senario 2 to corresponds to 3 connections to the same VPN server but the VPN IP addresses or source to the web host are obviously different.

A problem that I identified is that of senario 2: you have a bigger fingerprint / connection pattern, which is a problem. Visit obscure sites compared to popular sites.

This is assuming the user accepts latency and authentication issues or SSL, etc.

The nginx reverse proxy is slow, it has 499 points when load tests are in progress and its throughput is high upstream_connect_time

We are testing one of our application servers using Gatling by sending around 150 req / s. When we load test by calling the application server directly, everything works fine, but when we call via nginx, which acts as reverse proxy, there is a lot of waiting time (60s) at Gatling .

When looking at the nginx logs, we found cases where upstream_connect_time would be – & # 39;

{"log": "" 20 / Mar / 2019: 08: 26: 16 +0000  "client = 172.30.14.21 method = POST request = " POST / API / shopping / log HTTP / 1.1  "request_length = 5672 status = 499 bytes_sent = 0 body_byt
es_sent = 0 referrer = - user_agent =  "Mozilla / 5.0 (Windows NT 10.0; Win64; x64) AppleWebKit / 537.36 (KHTML, like Gecko) Chrome / 71.0.3578.98 Safari / 537.36 " upstream_addr = 172
.30.106.47: 80 upstream_status = - request_time = 60.000 upstream_response_time = - upstream_connect_time = - upstream_header_time = -  n "," stream ":" stdout "," time ":" 2019-03-20T08:
26: 16.593007324Z "}

or in some cases, upstream_connect_time goes to 31s

{"log": "" 20 / Mar / 2019: 08: 26: 00 +0000  "client = 172.30.14.21 method = POST request = " POST / API / shopping / log HTTP / 1.1  "request_length = 5672 status = 200 bytes_sent = 280 body_bytes_sent = 12 referrer = - user_agent =  "Mozilla / 5.0 (Windows NT 10.0; Win64; x64) AppleWebKit / 537.36 (KHTML, like Gecko) Chrome / 71.0.3578.98 Safari / 537.36 " upstream_addr = 172.30 .106.47: 80 upstream_status = 200 request_time = 31.154 upstream_response_time = 31.154 upstream_connect_time = 31.080 upstream_header_time = 31.154  n "," stream ":" stdout "," time ":" 2019-03-20T08: 26: 00: 35.356.3536Z "

So we imagine that this could be related to connections to an upstream server. We tried to activate Keepalive but that does not help. When we were trying to reduce the number of workers to 512, we got an error saying that "the link between the workers was not enough". Below you will find our nginx.conf file. What could be the problem here?

magento2 – The shipping methods of Magento 2 do not load in the 10th

I have a problem with the fact that the shipping methods do not only load at checkout in IE 10, but that all shipping methods of browsers load but only in IE 10. Shipping methods do not load, but once if I refresh the page, they load and they only occur in production mode only, but not in developer mode. Can we deal with this kind problem, help us. We use the work coming from one page to the checkout.

Unable to load the .csv R file on my new laptop

I am faced with a strange problem with R when loading a .csv file. Until last week, I was working on a mission in R after loading a .csv file with a value of over a million records.
I received a new laptop from the company and installed R as well as the following packages
library (dplyr)
library (lubricate)
library (hms)
library (stringr)
library (tidyr)
library (ggplot2)
library (gridExtra)
library (tidyverse)
library (chron)
library (corrplot)
library (rio)
library (data.table)
library (openxlsx)
library (readr)

But surprisingly, I am unable to execute the read.csv command to read the csv file. I use the following commands after giving the setwd command and got the errors shown below.

consumer_data <- read.csv ("ConsumerElectronics.csv", fileEncoding = "UTF-8-BOM")

Error in read.table (file = file, header = header, sep = sep, quote = quote ,:
no lines available as input

consumer_data <- read.csv ("ConsumerElectronics.csv", stringsAsFactors = "FALSE")
Error in read.table (file = file, header = header, sep = sep, quote = quote ,:
no lines available as input

I do not know what's causing this problem. Previously, I did not have this problem at all. Did I forget to install a package to read a csv file?
I want the code above to work. Do not provide any other solution, as this code worked previously and read the .csv file where it was stored.

Thank you.
Pavan.

.htaccess – Load other files (outside public_html) under index.php

I wanted to load every page under index.php with a simple index.php? do = login

For example when the link index.php? do = login or / S & # 39; identify / is open, the file login.php is charged (from the outside public_html), and everything is done under index.php instead of having a separate php file in public_html for each action!

That's what I've already tried, do I do it well? (I'm not sure that what I'm doing has security flaws, please kindly advise him)

index.php

<? php

// path to the application (outside public_html)
define (& # 39; FILESPATH & # 39 ;, APP. & # 39; .. / application / actions / & # 39;);

// default file
$ file_name = & # 39; home_page & # 39 ;;

// for example. index.php? do = login
if (isset ($ _GET['do'])) {
$ filename = rtrim ($ _GET['do'], & # 39;)
}

// Set the file path
$ fpath = FILESPATH. "{$ file_name} .php";

// Make sure the user has valid characters
if (preg_match (& # 39; / ^[A-Za-z0-9_]+ $ / $, $ Filename) !! == 1 OR! file_exists ($ fpath)) {
// Fault
require_once (& # 39; 404.php & # 39;)
die();
}

// load the file do =
require_once ($ fpath);

// Nothing comes over in index.php

login.php

<? php

// Load the template file header
require_once (& # 39; header_template.php & # 39;);


//
// What happens in login.php
// Like checking if the user name has valid characters, then search it with pdo in the database,
// password_verify (), etc ...
//


// After finishing the above things, load the HTML template connection.
require_once (& # 39; login_template.php & # 39;);

// Load the model footer
require_once (& # 39; footer_template.php & # 39;);

.htaccess

Running with site.com/login/ etc. instead of site.com?do=login


    
    
    
    RewriteEngine On
RewriteCond% {REQUEST_FILENAME}! -D
RewriteCond% {REQUEST_FILENAME}! -F
RewriteRule ^ ((? S). *) $ Index.php? Do = $ 1 [QSA,L]

unit – Webgl page segment size increases with each page load, then hangs

I get an instant problem or sometimes not enough memory when I reload my web page. I have a project webgl which is empty (just a camera + light), developed in unity3d. I recharge it and profile its memory.
enter the description of the image here

As you can see, its load is 1.2 MB first, then 1281 MB second, from 1574 to 2160, then a crash. I am amzed why is this happening?

The IndexedDB file system is another source of memory-related problems.
used by Unity. Whenever you cache a set of assets or use
methods related to file systems, they are stored in a virtual file system
supported by IndexedDB.

What you may not know is that this virtual file system is loaded
persistent in memory when you start your Unity application.
This means that if you use the default Unity caching mechanism
for asset sets, you add the size of all these sets to
the memory needs for your game even if they are not
charge.

but the problem is that I have not yet loaded this version.

javascript – Load the script after inserting the block

I've created a plug-in map block that works more or less, but I can not figure out how to load the map script when / after inserting the block. If I reload the page after inserting / saving, or if I load the public view, the map script loads as expected (since I've been queuing scripts and styles via PHP ). Normally I attach the script to a sort of DOM event, but I realize that Gutenberg / React handles things differently.

So my questions are:

  • How to load a script (remote or online) immediately after inserting my block?
  • How to set the properties of a block in a distant script that has been queued via PHP (that is, using props.setAttributes (), which is not available for scripts located outside of my block record)?

This is my first try at Gutenberg / React, but here's what I'm working on right now. I may miss some fundamentals.

php – Is it a good practice to load controllers

I am new to PHP and I mostly learn,

Is it a good practice to load controllers in PHP? (for a small and light application)

Does it have vulnerabilities? or is it good and can I pass writing my controllers?

<? php

// path to the application (outside public_html)
define ('APP', '../ application /');
// controllers
define (& # 39; CONTROLLER & # 39 ;, APP. & # 39; controller & & 39;);

// default controller
$ controller = & # 39;

// Check if the page is set (for example, index.php? Page = login)
if (isset ($ _GET['page']))
{
// Get the name of the controller and delete possible / from the end
$ controller = rtrim ($ _GET['page'], & # 39;)
}

// Set the controller path
$ file = CONTROLLER. "{$ controller} .php";

// control page
if (preg_match (& # 39; / ^[A-Za-z0-9_]+ $ / $, $ Controller)! == 1 OR! file_exists ($ path))
{
// Fault
require_once (& # 39; 404.php & # 39;)
die();
}

// load the necessary material
require_once (APP. & # 39; system.php & # 39;);

// load the controller
require_once ($ path);

// Nothing comes over in index.php

P. This is the bare bone with some extra stuff removed

P.S.S. I'm not trying to use MVC, just a way to load pages safely under index.php

Network – Load Balancing Performance: Sophos vs. Cyberoam

The results CR35iNG – 10.6.4 MR-1 and Sophos XG135 (SFOS 17.5.3 MR-3) are side by side and the load balancing comparison results are presented below:

Load balancing test with Sophos help
Load balancing test with Sophos help

Load balancing test with Cyberoam
Load balancing test with Cyberoam

I've already set the round robin method on Sophos:

define the wan-load-balancing weighted-round-robin routing

Both UTM are sitting next to each other and I just replaced my nic gateway to test them. There are 4 modems, 100 Mbps DL / 10 Mbps UL each. As you can see, Sophos is still slower than Cyberoam. What could be the problem with Sophos here?
