What You Need to Know About Private Proxies
Proxies serve several significant purposes, whether you want to go through SEO rankings in bulk, as a social media marketer, an online business owner, or a torrent user. And since proxies allow users to perform several tasks that are otherwise impossible, they are becoming quite popular these days. When you use proxies, you can bypass some restrictions like those on censorship and the geographical ones. Nevertheless, it may be quite challenging to choose one exactly for your needs with the plethora of private proxies providers available on the web.
If you want a great value, 24/7 support, and highly anonymous for your money, choose EzProxies as you will have the chance to use the company’s servers as an intermediary. It will be highly impossible for a website to tell you are using a proxy because Ezproxies utilizes its advanced technology.
What is a Private Proxy?
The type of proxy server that one person can exclusively use at a time is a private proxy. As it makes it untraceable, this proxy server will hide your IP address. Thus, your IP address will become masked if you are using a private proxy. Your local ISP will mask your IP address.
How the Private Proxy Works
You will figure out that you’re the only one using the proxy through authentication. A private proxy provider that will provide you with the authentication system as part of their services for their private proxies is essential before you buy a private proxy. Two ways of private proxy authentication include:
Whitelist IP Authentication
Whitelist IP authentication is an essential part of IP authentication. There is an IP address assigned to you when you purchase a proxy from a private proxy provider. You can use this IP for authentication as you have authorized access to proxies through this process.
Password and Username Authentication
Username and password is another method of authentication. As most internet users use this method, it is quite common. And because all that is required is to provide your login details, which are username and password, the process is quite easy.
Compared to the username and password method, the proxy is indeed the simplest, even though you can’t call it less secured. There are benefits and challenges with this method. You can only have access to the proxy from the Whitelist IP alone since you will have to use your private proxy provider to whitelist your IP address.
Types of Private Proxies
Private proxies are the type of proxy server that one person uses at a time. There are several types of private proxies, and you will have mobile IP proxies, private residential IP proxies, and private dedicated IP proxies. Because of their lesser chances of being tracked, these proxies are the best to use. It is quite essential to determine the type that you will apply according to your needs before you buy a private proxy.
Increase file descriptors in CentOS
To increase the amount of files descriptors in CentOS follow this tutorial. We hope this is useful, for some reason it is difficult to find a complete guide for this on the web. This guide will work in most versions of CentOS and Fedora
In this guide we will be raising the open file descriptor limit from 1024 to 65535.
Edit the following file:
|
1 |
/etc/sysctl.conf |
You will need to add the following line to the bottom of this file:
|
1 |
fs.file-max = 512000 |
Save and exit the file.
At the prompt type the following:
|
1 |
sysctl -p |
This will implement the settings.
Now we will edit the following file:
|
1 |
/etc/security/limits.conf |
Add the following line to the bottom of the file:
|
1 |
* - nofile 65535 |
Save and exit.
Type the following command.
Do this as root. This is to be sure that there are no errors:
|
1 |
ulimit -n 65535 |
Double check by typing ‘ulimit -n’. If the response is ‘65535’ everything is good and you are all set.
How to Configure iOS to use a Proxy
When you are configuring iOS to use a proxy server, you need to make sure that your proxy server is linked to every network that you access. In this article, we are going to show you how to configure iOS to use a proxy so that you don’t have anything to worry about.
PLEASE READ THE INSTRUCTIONS IN THE WELCOME EMAIL. YOU WILL NEED TO AUTHENTICATE YOUR IP ADDRESS FIRST.
How to Configure iOS to use a Proxy
1. Go to your “Settings.”
On your iPhone or iPad, open your “Settings.”
2. Click on “Wi-Fi.”
When you reach your Wi-Fi page, you should make sure that you are connected to the network that you want your proxy server to work with. If you are not, you should connect before going any further.
3. Click on the network that you wish to access. Scroll down until you reach the “HTTP Proxy” setting.
After clicking on the network that you wish to access, you will reach a page that is full of technical-looking information. This usually includes things like “DNS” and “Search Domains.” Scroll down the page until you reach the “HTTP Proxy” section.
4. Under “HTTP Proxy” click either “Manual” or “Auto.”
When you are configuring iOS to use a proxy, you need to decide whether you are going to be connecting manually or automatically. If you choose to connect automatically, your iPhone or iPad will automatically configure your settings for you. You will still have to enter your automatic proxy configuration script.
5. When setting up a “Manual” proxy server, make sure that you input all of your details properly.
If you click “Manual,” you will have to input your proxy server address and your port code. We would recommend checking these details twice so that you don’t have any issues. If you click the “Authentication” button, you will be prompted to input your username and password.
6. Add your proxy server to all of your networks.
Once you have added your proxy server details to one of your networks, you will have to add your proxy server details to any others that you want to access. We would recommend doing this all at once so that you don’t miss any.
7. Check that your proxy server is working.
Checking whether or not your proxy server is working on an iPhone or an iPad is really easy. If you go to Safari when it isn’t working, you will be met by a message that tells you that your server cannot be found. You’ll also encounter a similar message over in the App Store. If this happens, we would recommend fixing your proxy settings immediately so that you can access the internet.
How to Use a Proxy With Firefox
Setting up a proxy in Mozilla Firefox can be a little bit difficult if you’ve never set up a proxy before. This article will teach you how to use a proxy with Firefox in just a few easy steps.
BE SURE TO READ THE INSTRUCTIONS IN THE WELCOME EMAIL.
YOU WILL NEED TO AUTHENTICATE YOUR IP ADDRESS BEFORE YOUR PROXIES WILL WORK.
1. Click on the Mozilla Firefox menu – the icon with three lines in the top right corner.
When you open your Mozilla Firefox browser, click on the menu button at the top right-hand corner of your screen. This should be situated just beneath the close button.
2. Click on the “Options” button with the cog.
A small grid of menu options with icons will open. Click the “Options” button at the bottom of the menu. This button has a cog just above it.
3. On the left side, you’ll see a series of different icons. Click on the icon that says “Advanced.”
A new window will open with a series of different icons down the left side. You need to click on the “Advanced” button, a button with a witch hat icon.
4. Click on the button that says “Network.”
At the top of the “Advanced” page, there are a few different buttons in a row. Click on the button in the middle that says, “Network.”
5. Underneath the “Connection” heading, click on the “Settings” button so that you can configure how Mozilla Firefox connects to the Internet.
When you click “Settings,” you will be able to configure your proxies so that they work with Mozilla Firefox.
6. When your “Connection Settings” open, you’ll be presented with four different options. Click on the one that says “Manual proxy configuration.”
Once your “Connection Settings” pop-up opens, you will have to change it from whatever it is on to “Manual proxy configuration.” This will enable you to connect Mozilla Firefox to whichever proxy you would like to use.
7. Enter the details for your proxy server.
If you know the details for your proxy server, you will have to enter them now. Make sure that you double-check that you have all of the details right.
8. Double-check that your proxy server is working.
Using an IP checking website, check that your IP address is displaying the way that you want it to be displaying. If your proxy server is working, your proxy server’s IP address is the one that you will see.
Bash script to block a list of IP addresses using IPTABLES
In this article we show an example of a script that when run will block a list of IP addresses using IPTABLES. This is intended for complete beginners, so I have made sure to write everything out from start to finish. Please let me know if I have missed anything.
Occasionally we will need to block an IP address from one of our servers. Doing this from the command line using IPTABLES is a simple task. What happens though when you have more than one IP that needs blocked, or maybe even 100 IPs that you need to blocked? The answer is to use this Bash script!
Create a text file using your favorite editor. I prefer to use vi, so I would type the following.
|
1 2 |
cd ~ vi block |
This will create a file named ‘block’ in your root directory. Once vi opens the file hit ‘i’ to enter ‘insert’ mode in vi and paste the following script:
|
1 2 3 4 5 6 7 8 9 10 11 |
for i in `cat /root/ips|grep -v "#"` do ADDR=$i /sbin/iptables -t filter -I INPUT -s $ADDR -j DROP /sbin/iptables -t filter -I OUTPUT -s $ADDR -j DROP /sbin/iptables -t filter -I FORWARD -s $ADDR -j DROP /sbin/iptables -t filter -I INPUT -d $ADDR -j REJECT /sbin/iptables -t filter -I OUTPUT -d $ADDR -j REJECT /sbin/iptables -t filter -I FORWARD -d $ADDR -j REJECT echo "Block ALL INPUT from " $ADDR " net DROPPED." done |
Once you paste this hit your ‘esc’ key to exit ‘insert’ mode in vi, and then type ‘:wq’ to save the file and exit vi.
Notice on line one of the script the letters ‘ips’. This will be the name of the file that you will create with the IPs that you want blocked. Type the following:
|
1 2 |
cd ~ vi ips |
This will open vi again and create a file named ‘ips’. Type ‘i’ to enter ‘insert’ mode and on each line enter an IP address that you want blocked from your system. So something like this:
|
1 2 3 4 5 |
123.123.123.2 123.123.123.3 123.123.123.4 123.123.123.5 123.123.123.6 |
You can even block entire subnets like this:
|
1 2 |
123.123.123.0/24 123.123.125.0/24 |
Once you have completed entering the IPs that you want to block hit ‘esc’ and then ‘:wq’ to save and quit. You now need to execute the script. You will need to change the file permissions to ‘774’ to do this. Type the following:
|
1 |
chmod 774 block |
This will change the file permission to allow you to execute the file. Now run the script file. To do this type:
|
1 |
./block |
Your script will now run and all of the IPs that you entered in the ‘ips’ file will be blocked from accessing your system!
List all IP addresses available on a linux server
This article deals with Linux based systems.
While working with a server with many IP addresses you may need to list all of the IP addresses on the server. Most commands may give you more information than you may need. To get a list of only the IP addresses use the following command:
|
1 |
ifconfig | awk -F "[: ]+" '/inet addr:/ { if ($4 != "127.0.0.1") print $4 }' |
The IP address available on the server will be displayed in a list like this:
192.168.1.2
192.168.1.3
192.168.1.4
192.168.1.5
192.168.1.6
192.168.1.7
192.168.1.8
192.168.1.9
192.168.1.10
etc…
I have found that this makes it easier to cut and paste into a text file and then later add the IPs to a database.
Use a proxy with PHP and CURL
Here is a simple script to use a proxy in PHP with CURL.
This is an example if you are using IP authentication with the proxies:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
$proxy_ip = '123.123.123.123'; //proxy IP here $proxy_port = 3128; //proxy port that you use with the proxies $url = 'http://google.com'; //URL to get $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HEADER, 0); // no headers in the output curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // output to variable curl_setopt($ch, CURLOPT_PROXYPORT, $proxy_port); curl_setopt($ch, CURLOPT_PROXYTYPE, 'HTTP'); curl_setopt($ch, CURLOPT_PROXY, $proxy_ip); $data = curl_exec($ch); curl_close($ch); echo $data; |
If you are using the proxies with username/password authentication use the following code:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
$loginpassw = 'login:password'; //your proxy login and password here $proxy_ip = '123.123.123.123'; //proxy IP here $proxy_port = 8080; //proxy port that you use with the proxies $url = 'http://google.com'; //URL to get $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HEADER, 0); // no headers in the output curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // output to variable curl_setopt($ch, CURLOPT_PROXYPORT, $proxy_port); curl_setopt($ch, CURLOPT_PROXYTYPE, 'HTTP'); curl_setopt($ch, CURLOPT_PROXY, $proxy_ip); curl_setopt($ch, CURLOPT_PROXYUSERPWD, $loginpassw); $data = curl_exec($ch); curl_close($ch); echo $data; |
The Functions Of A Proxy Server
A private proxy server is basically a combination of single or multiple software and hardware that are designed in a way to provide certain networking facilities to customers. It could also be considered to be a software or hardware which provides services or some system which runs a server operating system.
Therefore a private proxy server could also be referred as to firewall mechanism which is present as a substitute of IP Address, for a protected host network, which has a temporary addresses for all kind of the information that is passing through. Decision are made by it whether to authenticate a certain client or user IP Address, to permit the network access and to establish connections on behalf of users, with some remote computer.
It is basically a computer which acts as an intermediary or interface in order to make connections between 2 or more computers, having varying protocols & that are present at different remote location over web.
When a user (computer) attempts to connect to another user to look for any resources such as files, web pages, connections, etc available on their database, it is the proxy server that evaluates if such connection is permitted according to the existing settings on the remote computer. When the private proxy server authenticates that these conditions are met, it then makes the request on behalf of the user and establishes the connection.
Proxy servers can respond to client or user, can also make modification of their requests, or respond to client’s request without making any contact with server. This is done by usage of the cached similar responses that are present at the remote server which are being requested from resources.
The other functions include:
1. Time is reduced to access certain resources.
2. For evaluation or auditing process, a log is served in order to give data on web.
3. Parental control or security gets over ride by it.
4. Regionally restricted resources are also accessible.
5. Due to security or anonymous browsing, clients are retained under cover.
6. Unauthorized site or unwanted stuff is blocked.
7. It also scans and filters the malware before making the delivery of requested resources.
8. It blocks some outgoing data, by serving as a scan. It is done for protected files.
Though, it acts as an intermediary, who basically do acts on behalf of more than 2 clients or users, proxy server may also be placed between clients, or at the destination servers that are present on web, in order to serve its functions.
Why should one buy a private proxy?
When one browses over the internet, they usually come across a great number of internet issues, some of these internet issues includes the installation of malicious software, which are commonly known as malwares. The question often arises what is malware? Malware can usually be said to be a computer virus. Malware includes every kind of virus in which includes Trojans, spywares, worms, root kits etc.
When one browses over the internet they may come across all such different types of malicious software, and normally a computer’s firewall is not able to stop all such malware. However if you want to protect yourself from such virus or other kind of intruding software that might risk your personal security, than one should go with buying a private proxy. A private proxy allows you to browse safely over the internet; as such proxy hides your IP address from different websites and servers that you visit which allows you to be absolutely safe from such viruses and intruding software.
When you plan to buy a private proxy for yourself or for your home then you would definitely have a great number of options to choose from, as most of the proxy selling websites allow you to select different kinds of package plan for your proxy. So you can select the one that’s fits you best and fulfills all your needs and requirements.
Most of the people try to go with free proxy sites, as they find it much more convenient for themselves to use such proxy rather than buying their own personal private proxy. However going with the website that allows you to use free proxy is really not a good idea, as such sites monitors all your moves and have a close on you. If these websites are operated by hackers than they will surely add some kind of spyware or adware into your PC which may trouble you in terms of future perspectives and is definitely not good when it comes to your personal security.
The other thing that these site might do that they might start sending you a bulk of spam mails, as they would save your user id, which they usually sell to product advertisement companies. Mark my words there is no such thing as “Free”, if someone is providing you with such “free” service than they will surely make money from you in some way or the other way. So it’s a good idea to buy a private proxy rather going with such free services.
