Better performance on P2P platformsSOCKS5 vs HTTP proxyShould you use SOCKS5 with a VPN? Should you use a free proxy? What is SOCKS5 proxy? SOCKS5 is the latest and most up-to-date SOCKS protocol. It is an improved version of SOCKS, an internet protocol that routes packets between a server and a client using a proxy server. SOCKS5 has enhanced security and offers three types of authentication methods: Null authentication – No authentication required to connect to a proxy;Username/password authentication – You need to provide login details to connect to a proxy;GSS-API authentication – Both you and the server use authentication methods at the operating system level to verify your does it work? Your traffic is routed through a proxy server that generates an arbitrary IP address before you reach your destination. Technically speaking, SOCKS5 (the latest version) uses proxy servers to form User Datagram Protocol (UDP) or Transmission Control Protocol (TCP) connections through arbitrary IP your IP is 1. 1. 1 and your traffic is routed through a SOCKS Proxy with the IP 2. 2. 2, the destination server (the website) will think that the request came from the latter. The website cannot see your original IP address. This helps you hide your location, but it doesn’t mean that your traffic is secure. Contrary to Virtual Private Networks (VPNs), proxies do not encrypt your traffic – it’s still out in the open and anyone can snoop on what you are is no such thing as an 100% anonymous SOCKS5 proxy server, because it’s impossible to be truly anonymous online. You can get close to it by being aware of what you do online, what services and security tools you use and how it all impacts your privacy. But no single proxy, VPN, or encrypted messaging app will make you ’s little chance you’ll be able to use streaming services that are not available in your country by connecting through a proxy. However, if you only want to change your virtual location and bypass simple geo-blocks, you can find a SOCKS5 proxy list online and try your luck. Check our brief video about SOCKS5 a SOCKS5 proxy better than a VPN? SOCKS5 is not as secure or as fast as a VPN. It’s easy to confuse a SOCKS5 proxy with a VPN, but there are curcial differences. Like most proxies, SOCKS5 won’t encrypt your data, and will lower internet speed and reover, SOCKS is quite detectable, so it most likely won’t get you around national firewalls. Due to this fact you need to enhance its security with a VPN. A good VPN, on the other hand, will encrypt your data as it travels from your device to the VPN server, ensuring that nobody can view it at any point on its journey. With a service like NordVPN, you can still get around internet restrictions and protect your IP address, but you’ll do so with genuine privacy and lightning fast internet speeds. Upgrade your privacy with high-quality VPN CKS5 proxy servers benefitsHere are 4 strong reasons to use SOCKS proxies:1. Gets you around internet blocksSince proxy servers act as relays between your device and the internet, they can easily help you bypass internet blocks. For example, if your IP was blacklisted by a certain website (or you use a VPN and its servers IPs were blacklisted) you can route your traffic through a SOCKS5 proxy and so bypass this block. However, it won’t help you to circumvent national firewalls in the way that a VPN will, as most of them use deep packet inspection (DPI). This means that your traffic is blocked by your ISP and before it reaches the website. Faster and more reliable connectionUnlike its predecessors, which only used TCP protocol, SOCKS5 proxy servers can use UDP protocol, ensuring a reliable connection and efficient TCP internet protocol forms a connection between a client and a server, making sure that all the packets arrive from one side to the other. It requires fitting the content into a fixed format so that it can be transferred easily. UDP, on the other hand, doesn’t focus on whether all packets from the client or server reach the other side and whether they are transferred in the same order. UDP doesn’t waste time converting data packets into a stream of fixed packets. Therefore, with these UDP at hand, SOCKS5 can offer faster speeds and a reliable connection. 3. Fewer errors and improved overall performanceMany other proxies rewrite data packet headers. Because of this, there’s a high chance of misrouting or mislabelling that data. SOCKS5 proxy servers do not rewrite data packet headers, so there is a lower chance for errors. Since there are far fewer errors, the performance automatically improves. However, this comes at a cost of your privacy and security as packet headers contain your personal information and can be easily identified. 4. Better performance on P2P platformsSOCKS5 is faster than other proxies because it transfers smaller data packets. Therefore, it offers faster download speeds, which is why many users use it to connect to P2P sharing websites and CKS5 vs HTTP proxyUnlike HTTP proxies, which can only interpret and work with HTTP and HTTPS webpages, SOCKS5 proxies can work with any proxies are high-level proxies usually designed for a specific protocol. While this means you get better connection speeds, they’re not nearly as flexible and secure as SOCKS proxies. SOCKS proxies are low-level proxies that can handle any program or protocol and any traffic without you use SOCKS5 with a VPN? The main difference between proxies and VPNs is that VPNs encrypt your traffic and proxies don’t. VPNs provide more stable connections while proxy connections drop more are few reasons to use both together, so your best bet is to choose the right tool for the job. Fortunately, NordVPN’s servers also support SOCKS5 connections. For full instructions on how to use SOCKS5 proxy on different platforms, visit our tutorial page. Should you use a free proxy? Because of their low overhead, proxy services aren’t expensive to run, but they still come with costs. Therefore, free proxies, like free VPNs, should be avoided. Here’s why:Poor performance. Free proxies will have less support personnel and may have less configuration options or slower infrastructure. All of this can make them slower and less secure. They might also reduce their speeds or turn off features in an effort to make you a paying ivacy issues. If you’re not paying for the service, you aren’t the customer. Free proxies can monitor user traffic and sell that data to third parties or serve ads. This means replacing ads on websites you love (thereby cutting into their revenue) or introducing new ads that weren’t there best bet is a premium proxy service, which will offer the best speeds, support, and security. Fortunately, when you buy NordVPN, you can also use some of our servers as SOCKS5 proxies. With all of our other features, you can easily switch between maximum security, maximum speed, or the best of both secure and flexible service offers tons of options, including SOCKS5.

SOCKS Proxy Primer: What Is SOCKs5 and Why Should You …

co-authored by Darshan S. Mulimath, Megha B. Sasidhar, and Ashiq Khader
In computer networks, a proxy or proxy server is a computer that sits between you and the server. It acts as a gateway between a local network and a large-scale network, such as the internet.
A proxy server works by intercepting connections between sender and receiver. All incoming data enters through one port and is forwarded to the rest of the network via another port.
Aside from traffic forwarding, proxy servers provide security by hiding the actual IP address of a server. They also have caching mechanisms that store requested resources to improve performance. A proxy server can encrypt your data so it is unreadable in transit and block access to certain webpages based on IP address.
Now that we have a general sense of how a proxy works, let’s zoom in on a specific type of proxy — SOCKS — and, specifically, the SOCKs5 variant.
What Is a SOCKS Proxy?
SOCKS, which stands for Socket Secure, is a network protocol that facilitates communication with servers through a firewall by routing network traffic to the actual server on behalf of a client. SOCKS is designed to route any type of traffic generated by any protocol or program.
A SOCKS proxy server creates a Transmission Control Protocol (TCP) connection to another server behind the firewall on the client’s behalf, then exchanges network packets between the client and the actual server. The SOCKS proxy server doesn’t interpret the network traffic between client and server in any way; it is often used because clients are behind a firewall and are not permitted to establish TCP connections to outside servers unless they do it through the SOCKS proxy server. Therefore, a SOCKS proxy relays a user’s TCP and User Datagram Protocol (UDP) session over firewall.
SOCKS is a layer 5 protocol, and it doesn’t care about anything below that layer in the Open Systems Interconnection (OSI) model — meaning you can’t use it to tunnel protocols operating below layer 5. This includes things such as ping, Address Resolution Protocol (ARP), etc. From a security perspective, it won’t allow an attacker to perform scans using tools such as Nmap if they are scanning based on half-open connections because it works at layer 5.
Since SOCKS sits at layer 5, between SSL (layer 7) and TCP/UDP (layer 4), it can handle several request types, including HTTP, HTTPS, POP3, SMTP and FTP. As a result, SOCKS can be used for email, web browsing, peer-to-peer sharing, file transfers and more.
Other proxies built for specific protocols at layer 7, such as an HTTP proxy that is used to interpret and forward HTTP or HTTPS traffic between client and server, are often referred to as application proxies.
There are only two versions: SOCKS4 and SOCKs5. The main differences between SOCKs5 and SOCKS4 are:
SOCKS4 doesn’t support authentication, while SOCKs5 supports a variety of authentication methods; and
SOCKS4 doesn’t support UDP proxies, while SOCKs5 does.
A SOCKs5 proxy is more secure because it establishes a full TCP connection with authentication and uses the Secure Shell (SSH) encrypted tunneling method to relay the traffic.
Why You Should Adopt SOCKs5
Below are four key benefits to using a SOCKs5 proxy with SSH tunneling.
1. Access Back-End Services Behind a Firewall
Usually, a cluster is hosted in the cloud behind a firewall to minimize potential security vulnerabilities. There are two ways to access any backend services that are running inside a cluster, and each has its limitations:
Expose backend services to public (and accept the associated security risk); or
Whitelist the client or user’s IP to allow traffic to backend services (this is not the right solution for when a user’s IP changes, however).
A SOCKs5 proxy with dynamic port forwarding using SSH can be an alternative to the two undesirable options above. An administrator or developer could access any backend services within a cluster that is hosted in the cloud behind a firewall for debugging, monitoring and administrating from a public network without exposing the backend service ports or whitelisting specific IPs.
Let’s look at a use case. For security reasons, the administration or monitoring application APIs or web user interface (UI) ports for monitoring Hadoop cluster are closed by default when hosted on the cloud. To access these APIs or web UIs, you can use SSH dynamic port forwarding to master or edge a node cluster, since the master node will have a public IP and run SSH services by default, which is exposed so the user can connect from outside.
For another example, say you’re working with a virtual private cloud (VPC). You can deploy a bastion host to securely access remote instances within a VPC by limiting their access to the outside world. You can access the bastion host from the outside world, and only port 22 (SSH) is opened. Using SSH dynamic port forwarding (SOCKs5 proxy), you can access the remote instances that are running in the VPC.
2. No Special Setup Required
SOCKs5 doesn’t require special setup, as long as you have SSH access to either the Edge node or gateway of a cluster. Therefore, users such as administrators and developers can access back-end resources behind the firewall using an SSH tunnel without requiring a virtual private network (VPN).
3. No Third-Party Public or Free Proxy Server in Your Deployments
Since a SOCKs5 proxy routes all kinds of TCP and UDP traffic to their respective service through SSH tunneling, no layer 7 application-related special proxies are required for each service to route application requests.
4. Fewer Errors, Better Performance
Unlike other application proxies, SOCKs5 does not rewrite data packets. It just relays the traffic between devices. Therefore, it is less prone to errors, and performance increases automatically.
How Does SOCKs5 Work in Practice?
Any CISO wouldn’t jump at the chance to embrace the benefits listed above. But what does a SOCKs5 proxy look like in the context of an enterprise security strategy? Where do security leaders begin when implementing SOCKs5 in their environment? Below are some key steps to help you get started.
Setting Up a SOCKs5 Proxy Connection
To SOCKSify an IT environment, the client application must have the capacity to support the SOCKs5 protocol. The syntax below is based on the SSH client on Linux; it shows how to create a SOCKs5 proxy server running on your local computer and then authenticate to the Edge node of a cluster or gateway hosted on cloud that routes traffic to the servers inside the cluster:
$ ssh -D 30001 [email protected] -C -f -N (password: xyz; or
$ ssh -i /path/to/private_key -D 30001 [email protected] -C -f -N
The above command starts the SOCKs5 server and binds to port 30001, then connects to Edge Node, Master Node or Gateway Node over the SSH tunnel hosted on the cloud.
The options used in the above command do the following:
D 30001 tells SSH to create a SOCKs5 server on port 30001 on the client computer.
C compresses data before sending.
N means “Do not execute a remote command. ” This is useful for simply forwarding ports (protocol version 2 only).
F requests SSH to go to the background just before command execution.
Accessing the Endpoints Using the SOCKs5 Protocol
Once a SOCKs5 proxy is created, configure your clients to access the internal services of the cluster. To keep it simple, we use a command line URL (cURL) that supports the SOCKs5 protocol. Other methods such as using a web browser require some additional setup and configurations.
The below cURL command shows how to access one of the HTTPS application endpoints listening on port 8000 behind a firewall using the SOCKs5 proxy over the SSH tunnel created above:
curl -x socks5hlocalhost:30001 -v -k -X GET EdgeNodeSSHserverIP:8000
The above cURL tool connects to port 30001 on localhost. Upon receiving a HTTP GET request on port 30001 from the cURL, the SSH client sends the same request via SSH tunnel to the SSH server.
The remote SSH server handles the request and passes the request to a back-end service listening at port 8000. The response is sent back to the client over the same SSH tunnel to the client’s SOCKs5 proxy. The proxy relays the response to the cURL, which displays the response.
Once you have created a SOCKs5 proxy using the SSH dynamic port forwarding method, you can also use the netcat utility to test the TCP connection. As shown below, a TCP connection test is made for back-end services listening at port 8443 with the SOCKs5 proxy:
ncat –proxy 127. 0. 1:30001 –proxy-type socks5 EdgeNodeSSHserverIP 8443 -nv
In Summary
A SOCKs5 proxy is a lightweight, general-purpose proxy that sits at layer 5 of the OSI model and uses a tunneling method. It supports various types of traffic generated by protocols, such as HTTP, SMTP and FTP. SOCKs5 is faster than a VPN and easy to use. Since the proxy uses a tunneling method, public cloud users can access resources behind the firewall using SOCKs5 over a secured tunnel such as SSH.
Breaking Down Differences Between SOCKS vs HTTP Proxy

Breaking Down Differences Between SOCKS vs HTTP Proxy

What Is a Proxy Server
Proxy servers are a great tool to help you access any websites or page using your browser.
Your identity remains hidden. For instance, if you want to access data from a company abroad, all you have to do is use a proxy server to conduct this action.
If the website only allows users from their country access, the proxy server will hide your location and pretend that you are residing from that particular company’s residence. No one will have a clue that you, sitting in India, are accessing companies’ data from abroad.
You can conduct this action easily when you have the right proxy servers in your hand. The finest two are called HTTPS proxy and SOCKS proxy.
These two are the most common, but their features are different. To help you decide which proxy is best suited for you, we are going to list out the difference using simpler terminology.

What Are HTTPS Proxies?
When you search in your web browser, you have found many links that start with “. ” When you see this, you must understand that the web page is using an HTTP protocol to function.
Http proxies function via a client and server model. For instance, being the client, you will type in the web browser to access some information. Your HTTP protocol will send the request for your access in the form of a URL link. The server on the other end will respond to that link along with the information you requested back to you. The resource you receive will also be in HTTP format.
In HTTP, you can conduct safer actions with the help of multiple proxy servers available in the market today. The HTTP proxy will function just the way it did above but with a proxy server; it will be easier to safeguard your identity.
Having understood what proxies are, let’s move towards the next popular proxy.
What Is a SOCKS Proxy?
Lightproxies states “SOCKS is a type of internet protocol that sends network packets from the server to the client and vice versa via a proxy server. ’’
A SOCKS proxy, which is referred to as Socket Secure, manages information online with the use of a proxy server.
Over here, the SOCKS proxy uses its SOCKS protocol. Unlike proxies, SOCKS proxies are more dependable when compared to.
As you now have a brief understanding of what the above two proxies’ functionality, we can jump to the crucial part of choosing which proxy would be ideal for you.
Difference Between SOCKS and HTTP Proxies
1. Functionality
HTTPS Proxy
SOCKS
Functions using protocol and is vital for those users you use it for the purpose of retrieving information via a web browser
Doesn’t use a proxy and is considered to be a lower level proxy since it is used for general purposes mostly
HTTPS proxies use only HTTP protocol, which means their functionality depends on what they follow. Since they conduct the action of retrieving information via the web browser, they are best suited for users who would use it for the same purpose.
Unlike, SOCKS functions a little differently. It doesn’t function using an HTTP protocol. This doesn’t restrict it from allowing users to view information online. Ideally, SOCKS is used for more general-purposes and is considered to be a lower level proxy.
This, however, isn’t a disadvantage because they are not liable to a particular set of network protocols, thus giving their users the flexibility to utilize this proxy anywhere.
2. Security
High chances of your data being viewed during the process
Low chances of your data being viewed since SOCKS can’t read data
The whole agenda of using a proxy is to remain safe and covered while accessing information online. As mentioned earlier, proxy servers are a great medium to safeguard your online activities.
The best part is that SOCKS proxies utilize it hence ensuring a good security weight when compared to HTTP proxies.
With HTTP proxies, there are chances of your data being viewed and recorded during the client-server proxies taking place. If this happens you remain at high risk. With SOCKS proxy this issue cannot occur since the proxy isn’t able to read the data.
But if you continue to use an HTTP proxy, you can remain safeguarded online by establishing a tunnel connection. The tunnel functions as a wall where it makes your activities online harder to be traced and leaves you more safe and secure to continue functioning.
3. Speed
Offers private and public proxy, depends on the choice ( Public proxy- slow)
Generic server, speed is fast
HTTPs proxies offer you 2 types of proxies to invest in when it comes to speed, Private and Public proxies.
With private proxies, you can single-handedly manage your online activities without any hassle. With public proxies, it is the opposite. Since the users are high, the speed gets affected where the internet will take a long time to even help you access a web page you want to see.
With SOCKS proxy being a general one, it is simple and quicker with its speed. It reduces the need for any code to be applied and hence it is ideal to transfer or download data from online.
Also ensure that apart from these proxies, you also need to search for well-established proxy companies that offer this service because, with the servers they offer, the internet and bandwidth speed can also help you function better for all your online activities.
4. Connecting with Tools
HTTPS proxy
Connects with any tool
Connects to limited tools
Either of these two proxies must be able to connect with the tools that you use.
HTTP proxy servers mostly connect with all tools, but with SOCKS proxy you might not be able to connect too as many devices when compared to HTTPS. Hence, it is essential that you keep track of which tools you utilize the most and then decide which proxy you want to apply.
The best way you can do this is by researching the various proxy servers available in the market.
It has various options to choose from and also has a dedicated section for SOCKS proxy users where you can benefit many of the advantages they offer under it. Also, you can keep track of the tools that are a fit for HTTPS and SOCKS proxy so that you can easily decide which one you can use.
The Bottom Line
As new technology arises, online platforms become much easier to crack. Viewing information and tapping crucial data for the wrong purpose have all urged companies to take strict measures in all their online activities.
With the differences mentioned above, for users who highly depend on downloading and transferring huge amounts of data, SOCKS would be the ideal one for you. For those who want to download a smaller amount of data, you can opt for the HTTPS proxy.
When it comes to choosing your proxy server to ensure that you invest in a brand that keeps three things in mind:
Keeps you anonymous.
Secures your online activities without any hassle or risks.
Has a good internet speed option.
